Executive Summary

The purpose of this report is to provide information to several stakeholders and to satisfy the regulatory

requirements of the Safe Drinking Water Act (SDWA) including the Drinking Water Quality Management

Standard (DWQMS), and regulatory reporting required under O.Reg. 170/03 (Section 11 and Schedule

22). The report is a compilation of information that helps to demonstrate the ongoing provision of a

safe, consistent supply of high quality drinking water to customers located within the City of Guelph and

the Gazer Mooney Subdivision (located in the Township of Guelph/Eramosa).

Water Services is a municipally-owned and operated water utility established in 1879. The Guelph

Drinking Water System (Guelph DWS) is a Class IV Water Distribution and Supply Subsystem and is

composed of water supply and treatment facilities and a water distribution system. The Gazer Mooney

Subdivision Distribution System (Gazer Mooney SDS) is a Class I distribution system supplied with water

from the Guelph Drinking Water System.

Both the Guelph DWS and the Gazer Mooney SDS are required to comply with the Safe Drinking Water

Act (SDWA) and Regulations as well as requirements contained in Permits to Take Water (PTTW),

Municipal Drinking Water Licences (MDWL), and Drinking Water Works Permits (DWWP). Having met the

quality management system requirements of the SDWA, Guelph Water Services is an accredited

Operating Authority with an up-to-date Operational Plan (OP). The OP is available upon request from

Guelph Water Services.

The source of Guelph’s drinking water is a series of 21 operational groundwater wells and a shallow

groundwater collector system; this system consists primarily of true groundwater sources, with some

“groundwater under the direct influence of surface water with effective filtration” (GUDI-WEF) sources

(i.e. Carter Well field, Arkell 1 and the Glen Collectors).

The City has approximately 41,653 fully metered water service connections, 542 kilometres of

underground watermains, and a population of approximately 126,250 within the City of Guelph. The

Gazer Mooney Subdivision has approximately 70 fully metered water service connections, 2 kilometres

of underground watermains, and an approximate population of 200.

There were no incidents of non-compliance (described in Section A of this report) associated with the

Guelph DWS and Gazer Mooney SDS in 2014. As the Operating Authority for both systems, Guelph

Water Services is annually inspected by the Ontario Ministry of the Environment and Climate Change

(MOECC) for compliance with regulatory requirements. The results of the 2014 Ministry of the

Environment and Climate Change (MOECC) Annual Inspection Report for the Guelph DWS and Gazer

Mooney SDS are still pending.

From Jan. 1 to Dec. 31, 2014, Guelph Water Services reported three Adverse Water Quality Incidents

(AWQIs) in the Guelph Drinking Water System: one of the incidents involved the detection of Total

Coliform at a well site above regulatory limits; the next incident was related to sodium results above the

reporting threshold, but within the aesthetic objective; and the last incident was related to temporary

UV disinfection system failure. There was one AWQI in the Gazer Mooney Subdivision Distribution

System related to sodium results above the reporting threshold, but within the aesthetic objective. In

conjunction with Wellington-Dufferin-Guelph Public Health and the MOECC, all appropriate corrective

actions and reporting were completed.

Water Services’ risk assessment updates, emergency response testing, internal and external audits help

facilitate continual improvement of processes and systems through the implementation of corrective

actions.

The water system is operated to meet daily, seasonal, and other operational demands (fire demands)

with various combinations of supplies in operation at any given time. From Jan. 01 to Dec. 31, 2014, a

total of 16,594,145 cubic metres (16.6 billion litres) of water was treated and pumped to the system.

The average daily water demand was 45,463 cubic metres (45.5 million litres). The highest daily use of

water occurred on Jun. 17, when 52,614 cubic metres (52.6 million litres) of water was pumped. The

minimum day production of water was 32,644 cubic metres (32.6 million litres) and occurred on Dec.

26, 2014.

All water provided to the Guelph Drinking Water System and the Gazer Mooney Subdivision Distribution

System was treated with sodium hypochlorite (for chlorine disinfection) with some sources also using

ultraviolet disinfection (UV). All supplied water was tested and met all regulatory standards.

City Guelph Water Services maintained the drinking water system in a fit state of repair and followed

best industry practices during the repair and maintenance of the system.

Details of ongoing and emerging water quality, supply, and distribution initiatives are outlined in Section

J of this report and include successful programs related to: water conservation, source water protection,

and lead reduction. Water Services continues to implement recommendations of the Water Conservation

and Efficiency Strategy, awaits MOECC approval of its policies to manage significant drinking water

threats through the proposed Grand River Source Protection Plan, continues to invest in the Arkell

Springs Forest Stewardship Project (to protect the Arkell Wellfield’s source water quality), and is

successfully implementing its extensive Lead Reduction Plan in accordance with the regulatory relief

provisions of the SDWA. The Lead Reduction Plan is partially grant-funded, and from Jan. 1 to Dec. 31,

2014, there were 11 full or partial replacements of lead service water lines.

Water Services’ Operational Testing and Adaptive Management Plan continues to assess the aquifer in

the area of the Arkell Wellfield and pumping conditions to determine a sustainable capacity with respect

to environmental conditions in the area. Infrastructure review occurs regularly between Engineering and

Water Services to optimize priority projects and minimize common costs. Work related to the Water

Supply Master Plan update is ongoing.

The City maintained a robust backflow prevention program overseeing 2,652 properties with 6,149

backflow prevention devices installed. There were no reported backflow incidents.

The City has completed this Annual & Summary Report to satisfy the regulatory requirements of the

Safe Drinking Water Act, O.Reg 170/03 (Section 11 and Schedule 22). For more information please

Systems Overview


The mission of the City of Guelph’s Water Services department (“Water Services”) is to provide customers

and the community with a safe, consistent supply of high quality drinking water while meeting, exceeding,

and continually improving on legal, operational, and quality management system requirements.

Water Services provides and promotes reliable, cost-effective systems for the safe production and delivery

of consistently high quality water.

Water Services is a municipally-owned and operated water utility established in 1879. The Guelph

Drinking Water System is a Class IV Water Distribution and Supply Subsystem and is composed of water

supply and treatment facilities and a water distribution system. From Jan. 1 to Dec. 31, 2014, thirty-five

water operators and staff were certified to operate and maintain the water systems.

Water Services maintains full scope accreditation to the Drinking Water Quality Management Standard

after a successful on-site audit in June 2014 conducted by a third-party accreditation body. This full

accreditation satisfies part of the requirements under the Municipal Drinking Water Licensing Program.

The distribution system (including watermains, valves, fire hydrants, services, and meters) serves a

population of approximately 126,250 within the City of Guelph. All new system components meet NSF 611

requirements or approved equivalents and are installed and maintained in accordance with approved

industry standards. The system is fully metered.

The Guelph Drinking Water System distribution system is comprised of the following infrastructure:

- 6.38 kilometres of 900-1,050 mm diameter water supply aqueduct;

- five underground storage reservoirs with a combined approximate capacity of 48,000 cubic metres

(48 million litres);

- three water towers with a combined approximate capacity of 11,200 cubic metres (11.2 million

litres);

- approximately 542 kilometres of buried watermain with a diameter < 900 mm;

- approximately 4,062 watermain valves;

- approximately 2,698 fire hydrants; and

- approximately 41,653 water services and water meters.

The source of Guelph’s drinking water is a series of 21 operational groundwater wells and a shallow

groundwater collector system; this system consists primarily of true groundwater sources, with some

“groundwater under the direct influence of surface water with effective filtration” (GUDI-WEF) sources (i.e.

Carter Well field, Arkell 1 and the Glen Collectors). The Guelph Drinking Water System uses 12 per cent

1 NSF/ANSI Standard 61: Drinking Water System Components -- Health Effects


Page 4 of 77

Sodium Hypochlorite (that is NSF 602 certified) for primary disinfection at 10 locations and for multi-

barrier primary disinfection at three locations. At three locations, ultraviolet light is also applied as part of

multi-barrier primary disinfection. At two locations, NSF 60-certified sodium silicate is used for aesthetic

purposes to sequester dissolved iron and manganese. In total, Water Services operates and maintains 31

facilities for water. These facilities perform the following functions: sources, supply, treatment, storage or

transfer.

The replacement cost of the entire system (excluding Gazer Mooney Subdivision Distribution System) is

estimated to be $541.5 million or approximately $4,400 per capita. The majority of Guelph Drinking Water

System operations are funded directly from the sale of water, with minor additional funding through

government grant programs. Property taxes are not used to fund operation or maintenance of the system.

From Jan. 01 to Dec. 31, 2014, a total of 16,594,145 cubic metres (16.6 billion litres) of water was

treated and pumped to the system. The average daily water demand was 45,463 cubic metres (45.5

million litres). The highest daily use of water occurred on June 17, when 52,614 cubic metres (52.6 million

litres) of water was pumped. The minimum day production of water was 32,644 cubic metres (32.6 million

litres) and occurred on Dec. 26, 2014.

From Jan. 1 to Dec. 31, 2014, all regulatory microbiological and chemical quality samples were taken by

certified operators and tests performed by accredited, licensed laboratories on water samples collected

throughout the drinking water system. These tests include both regulatory and operational testing – in

most cases only regulatory reporting is included in this report. In all cases, the drinking water supplied to

all customers was confirmed safe and the water was of higher quality than all Ontario and Canadian

health-related guidelines.

The Guelph Drinking Water System is defined as a large residential system operated under the regulatory

requirements of the Safe Drinking Water Act and the Ontario Water Resources Act (accessed at

http://www.e-laws.gov.on.ca). The Guelph Drinking Water System operated under Municipal Drinking

Water Licence (MDWL) 017-101 (issue number 5 and 6) and the Drinking Water Works Permit (DWWP)

017-201 (issue number 3, 4, and 5).

The MDWL and the DWWP describe system-specific requirements that are supplementary to provincial

regulations and act as licences for water supply and distribution operations. These documents outline

specific conditions and requirements regarding operation, maintenance and upgrades that are required by

the system and are considered regulatory in nature. These documents are available by request for viewing

at 29 Waterworks Place, Guelph.

The Gazer Mooney Subdivision Distribution System is a Class 1 Distribution Subsystem that serves

approximately 200 people, and is owned by the Township of Guelph/Eramosa. The system is operated by

Water Services by a legal agreement that was last signed by representatives of the City of Guelph and the

Township of Guelph/Eramosa on July 30, 2009. The terms of the agreement apply until May 31, 2019. All

of the water for the Gazer Mooney Subdivision Distribution System is supplied from the Guelph Drinking

Water System. All water is treated to provincial standards in the Guelph Drinking Water System and no

further treatment chemicals are added to the Gazer Mooney Subdivision Distribution System.

All new distribution infrastructure components meet NSF 61 requirements or approved equivalents and are

installed and maintained in accordance with approved industry standards. The system is fully metered.

The Gazer Mooney Subdivision Distribution System is comprised of the following infrastructure:

- approximately two kilometres of buried watermain with a diameter < 900 mm;

- approximately six watermain valves;

- approximately six fire hydrants; and

- approximately 72 water services and water meters.

The cost of construction of the Gazer Mooney Subdivision Distribution System was listed as $197,933 in

1980.

The Gazer Mooney Subdivision Distribution System is considered a small residential system and is

operated under the regulatory requirements of the Safe Drinking Water Act and the Ontario Water

Resources Act which may be found at http://www.e-laws.gov.on.ca.

The Gazer Mooney Subdivision Distribution System operated under Municipal Drinking Water Licence No.

104-103 (issue number 1), and Drinking Water Works Permit No. 104-203 (issue number 1). These

documents are available by request for viewing at 29 Waterworks Place, Guelph and at Township of

Guelph/Eramosa, 8348 Wellington Rd. 124, Rockwood.

Summary Water Services Report

a) Incidents of Regulatory Non-Compliance

This section describes all incidents of non-compliance (excluding those defined as “Adverse Water Quality

Incidents” (AWQI) reported in Section B of this report).


There were no incidents of non-compliance associated with the Guelph Drinking Water System in 2014

(Jan. 01 to Dec. 31).

The results of the 2014 Ministry of the Environment and Climate Change (MOECC) Annual Inspection

Report for the Guelph DWS and Gazer Mooney SDS are still pending.


There were no incidents of non-compliance associated with the Gazer Mooney Subdivision Distribution

System in 2014 (Jan. 01 to Dec. 31).

The results of the 2014 Ministry of the Environment and Climate Change (MOECC) Annual Inspection

Report for the Guelph DWS and Gazer Mooney SDS are still pending.

b) Adverse Water Quality Incidents

This section describes all “Adverse Water Quality Incidents” (AWQI). This term refers to any unusual test

result from treated water that does not meet a provincial water quality standard, or situation where

disinfection of the water may be compromised. An adverse water quality incident indicates that on at least

one occasion and at a certain instance in time, a water quality standard was not met. On average, the

Guelph Drinking Water System processes four to five AWQI’s annually.

The process of water quality sampling and testing can result in false positive results for contaminants;

these results can be caused by contaminated sampling containers and equipment, sampling technique,

sample handling and transportation, and sample analysis. In almost all cases, mandatory follow-up

sampling and analysis confirms that contaminants are not present in the water provided to customers.

Please note: Any residential tap lead sample results collected as per the Regulatory Lead Sampling

Program above 10 µg/L are tracked and reported separately to the Public Health Unit, the Ministry of the

Environment and Climate Change (MOECC) and the customer, and will be addressed as per the City’s Lead

Reduction Plan. The Regulatory Lead Sampling program has been replaced with the Lead Reduction Plan

(LRP) – see Section J for more information.


From Jan. 1 – Dec. 31, there were three adverse water quality incidents (AWQI’s #115902, #116157,

#120786) and a summary of these is included in Table 1: Summary of Guelph Drinking Water System

Adverse Water Quality Incidents.

c) Deviations from Critical Control Point (CCP) Limits and Response Actions

This section describes any deviation from essential steps or points in the drinking water system at which

control can be applied to prevent or eliminate a drinking water hazard or to reduce it to an acceptable

level. These essential steps or points in the system are known as critical control points (CCP). The CCPs

are used to identify control measures that are in place to address hazards and hazardous events. These

CCPs are in part stipulated by regulation and in part derived through risk assessment of the Drinking

Water System.

Water Services’ Critical Control Points include:

- primary disinfection,

- secondary disinfection, and

- backflow prevention.

Additional information (e.g. critical control limits and response actions) is included in Appendix “A” in the

“Summary of Critical Control Points and Critical Control Limits”.

Deviations from the CCPs are reported to both the Owners and Top Management, and are summarized in

the tables included in Section B of this report. There was one confirmed deviation from CCP Limits in 2014

(described in Table 1 as AWQI #120786).

d) The Efficacy of the Risk Assessment Process

This section confirms the occurrence of reviews of the risk assessment process to determine the

effectiveness of the process in identifying and appropriately assessing the risk of hazardous events and

hazards, and in identifying the appropriate control measures, critical control points (CCPs) and related

critical control limits (CCLs).

The annual risk assessment review described in “QMS 07 Risk Assessment” was conducted by Water

Services’ Continuous Improvement Team Members on Feb. 12, 2014, subsequently approved at a

Management Review Meeting on Apr. 11, 2014 and presented in Table 3 (in summary format) within this

report.

e) Internal and Third-Party Audit Results

This section describes any of the audit outcomes identified to date that require follow-up actions.

6 Risk Ratings are based on the risk calculation (likelihood rating x consequence rating), as included in the "QMS 08 Risk Assessment

Outcome" document: "Low" risk: 1 to 5; "Moderate" risk: 6 to 11; "High" risk: 12 or higher

7 Cells with GREEN highlights indicate that Water Services has determined there are sufficient control measures to adequately

control the risks. Items highlighted in YELLOW and RED indicate risk areas that are not sufficiently addressed through existing

control measures, and require additional work. + - Improvement being made

Internal auditing and third-party auditing is performed to fulfill the mandatory requirements of the

Drinking Water Quality Management Standard (DWQMS). The internal audit is completed using trained

internal staff. The purpose of audits is to evaluate the level of conformance of Water Services to the

DWQMS. Audits identify both conformance and non-conformance with the Standard as well as

opportunities for improvement.

The 2014 internal process audits were completed on May 15 to 23, 2014. Internal audit findings are

related to QMS orientation training updates for current and any new staff (QMS 04). Various opportunities

for improvement suggested by staff were also noted in the internal audit report. The next scheduled

internal audit will take place in January 2015 so that there is a separation between annual internal and

external audits. The month of December will be targeted in the future as the new annual internal audit

period. This will also allow proper time for following up on corrective actions and opportunities for

improvement. It will also present the opportunity to verify effectiveness of actions taken to address

findings between internal and external audits.

The 2014 third-party external on-site audit was completed on Jun. 10 to Jun. 12, 2014. There were no

nonconformities identified during this audit. Noted opportunities for improvement by the auditor were

related to improving the following processes: communications (QMS 12); and tracking improvement items

(QMS 21). These opportunities for improvement will be followed-up on by the auditor at the next on-site

audit in Jun. 9-11, 2015.

f) Results of Emergency Response Testing

Emergency response testing is regularly completed as a component covered by the Water Services’

Quality Management System (QMS) to ensure that Water Services maintains a reasonable readiness to

deal with emergencies. The ability to deal with emergencies is critical in demonstrating that Water

Services has taken a diligent approach to operating the Guelph Drinking Water System.

Feedback from this testing and from actual events is gathered during debriefing sessions and

improvement items are incorporated into the Water Services Emergency Plan and /or daily operations.

During the winter of 2014, Guelph experienced seventy-six frozen services (with sixty temporary lines

installed), the greatest number in one season since 1993. Typically, there are six frozen service lines in a

winter season. For each frozen service event, immediate actions were taken by staff to prevent any

further complications. Water Services staff continue to work on closing corrective actions initiated from

debriefing sessions related to Winter 2014’s frozen services and ice storm events that occurred in 2013.

Table 4 includes the dates of Completed Emergency Response Tests for the past three years.

g) Operational Performance and Statistics

The following section describes Operational performance statistics within Water Services that includes:

− 2014 Totalized Pumpages as per the Municipal Drinking Water Licence and Permits to Take Water;

− 2014 Instantaneous Flows as per Permit to Take Water requirements;

− Water Production and Population;

− 2014 Collector Flows; and

− Other Operational Performance Data.

2014 Totalized Pumpages and Instantaneous Flows (Jan. 01 to Dec. 31).

The Safe Drinking Water Act (SDWA) and the Ontario Water Resources Act (OWRA) each require that

operating authorities record and report both water takings as governed by Permits to Take Water

(PTTWs), and water being supplied to the City of Guelph.

Summaries of total water pumped, instantaneous flows and capacity (flows and volumes compared to

rated capacities) by the City of Guelph can be found in Appendix “C” – Total Water Pumped and

Instantaneous Flows.

8 “Water Shortage” and “Damage to Main Supply...” hazardous events are being deferred until the lessons learned and corrective

actions from the 2013 and 2014 events are adequately addressed.

2014 Totalized Pumpages (Jan. 01 to Dec. 31).

Figure 3 below depicts the water pumpage rate in cubic metres per day (m3/day) that is averaged each

week.

Figure 3: 2014 Totalized Pumpages (Jan. 01 to Dec. 31)

Water Services processed 16,594,145 cubic metres (16.6 billion litres) of water to the distribution system

in 2014 (Jan. 01 to Dec. 31). This represents 2.4 per cent more water being supplied to the distribution

system in 2014 as compared to the same time period in 2013 and 0.5 per cent more water than in 2012.

The average daily water demand was 45,463 cubic metres (45.5 million litres). The maximum day

production of water in 2014 was 52,614 cubic metres (52.6 million litres) and occurred on Jun. 17, 2014.

The minimum day production of water in the same time period was 32,644 cubic metres (32.6 million

litres) and occurred on Dec. 26, 2014.

Possible explanations for water use changes include: economic conditions (“an economic downturn”),

seasonal variations (sufficient precipitation that is conducive to lower outside water use), conservation

program outreach and education, and water loss associated with infrastructure demand due in part to the

harsh winter (frozen services and watermain breaks).

Collector Flows

The Arkell Spring Grounds Collectors (“Collectors”), one of Guelph’s many water sources, consist of a

gravity-fed under-drain system that collects shallow overburden groundwater. This system has been in

use since the early 1900s and can represent as much as 40 per cent of the total city-wide daily water

production. When the output of this source is reduced, Water Services is required to make up the

difference from other water supplies. Throughout the year, the production from this water supply varies

from an approximate low of 4,000 cubic metres (4 million litres) up to an approximate high of 20,000

cubic metres (20 million litres) per day.

The Collectors can also be used as a measurable index of the state of the environment (i.e. very dry to

very wet as they respond to rainfall and other environmental conditions). The volume of water that the

Collectors produce is one of the benchmarks used in the decision-making process to determine the

appropriate level for the City’s outside water use program.

Seasonally, between April 15th and November 15th, the City has a PTTW (permit to take water) that allows

water to be pumped from the Eramosa River to a pond and trench-based “Recharge System”. In the

Recharge System, the river water is filtered in-situ through the ground and approximately 50 per cent of

the flow is captured in the Glen Collector System. It should be noted that the Recharge System has not

been utilized from 2011 through 2014 in order to accommodate the Arkell OTP/AMP (Operational Testing

Plan / Adaptive Management Plan) which is a condition of the Arkell Well Field PTTW (Permit to Take

Water).

The productivity of the Collectors can also be used as a predictive tool. If the production volume from the

Collectors is low, then it can be assumed that other water supplies would be needed to make up the

difference. This may alter how regular maintenance is performed as well as the urgency with which repairs

are made to supplies that unexpectedly go off-line as they may be needed to supplement overall

production for the City when the Collector System is unable to produce a sufficient supply.

The Collectors have produced 3,076,164 cubic metres (3.0 billion litres) of water in 2014 (Jan. 01 to Dec.

31). This represents 13.6 per cent more water as compared to the same time period in 2013 and 42.7 per

cent more water than in 2012.

Note: This information should not be used in isolation as a predictive tool.

For a visual representation, please refer to Figure 5: 2014 Glen Collector Volumes (Jan. 01 to Dec. 31):

2014 Glen Collector Volumes (Jan. 01 to Dec. 31).

Figure 5 below depicts the Glen Collector flow rate in cubic metres per day (m3/day) that is averaged each

week.

h) Raw and Treated Water Quality – Guelph Drinking Water System

This section describes the water quality monitoring, both regulatory and operational, that has been

completed in 2014 (Jan. 01 to Dec. 31).


Page 20 of 77

Water Quality Review – Guelph Drinking Water System

Under the Safe Drinking Water Act (SDWA), municipalities are required to monitor both the raw and

treated quality of the source water supplied. This monitoring is performed for both regulatory compliance

and due diligence and is expected to identify any changes within the treated water as well as in raw

source waters.

A note about all tables included in this section:

1. All regulated chemical parameters where values above the lab’s MDL (minimum detection limit)

have been detected in the City of Guelph’s treated water sources are underlined indicating a

hyperlink to an Excel Workbook in Guelph’s electronic document management system (EDMS).

Note: EDMS is available for internal use only. The workbook contains a definition of the parameter

and an Excel worksheet for each treated source where the parameter has been detected with

values for all sample results from Jan. 01, 2007 to Dec. 31, 2014. This database is used to closely

track the instances of the identified chemical parameters and therefore provide time for planning /

budgeting if treatment or an alternative supply is eventually required due to the presence of a

given parameter. The database is updated semi-annually.

2. Tabulated values are from best available information at the time of table creation. While the values

above satisfy the regulatory minimum regulatory requirements, Water Services performs many

additional operational tests not listed in this report.

3. All acronyms and initialisms included in tables are described in Appendix “E” – Index of Terms,

Acronyms and Initialisms.

The following section summarizes daily Distribution free chlorine residual test results required by O. Reg.

170/03 Schedule 7-2 where “secondary disinfection” is provided for the period of Jan. 01 to Dec. 31,

2014. The Verney Tower sample point is used to represent the water quality provided by the Zone One

distribution system pressure zone and the Speedvale Tower sample point represents the water quality

provided by Zone Two for the purposes of the regulation. Please note that the City of Guelph takes

additional “operational” daily Distribution samples and tests for free chlorine residual in order to better

monitor the free residual in the Distribution System and respond accordingly. There was no instance of an

adverse result in 2014 (Jan. 01 to Dec. 31):

Treated Water Quality Statistics – O. Reg. 170/03 Schedule 6-5 - “Continuous Monitoring”

Results Summary

Water Services utilises over twenty regulatory and operational continuous monitoring devices to measure

water quality. Each regulatory device has controls associated with it such that in the event that the device

detects that a measured value is outside the acceptable parameters for that location, the device causes an

alarm to be sent to an operator for immediate response (24 hours per day seven days per week) and

either automatically shuts down the station or activates a second alarm for immediate operator response.

Both the minimum allowable levels (if applicable) and the target values for Water Services regulatory

continuous monitoring devices are listed below. The target values represent a safety margin to help

ensure that regulatory requirements are satisfied at all times. Please note that with the exception of the

values reported in the AWQI section of this report if applicable (Section B), continuous monitoring values

all fell within acceptable regulatory standards in 2014 (Jan. 01 to Dec. 31).

Treated Water Quality Statistics – O. Reg. 170/03 Schedule 13-6 and 13-7, “Three Month”

Sampling Results Summary

In 2014, all operational Treated Sources were sampled and analyzed for Schedule 13-6 and 13-7

parameters as per O. Reg. 170/03.

Regulation 170/03, Schedule 13-6 requires a minimum of one distribution sample taken from the

Distribution System where THM’s (trihalomethanes) are most likely to develop (locations with high

retention times). Water Services uses Speedvale Tower and Clair Tower for this purpose in the Guelph

Drinking Water System. The Maximum Allowable Concentration (MAC) for THM’s is 0.1 mg/L. However, for

this parameter the MAC uses a running annual average of quarterly samples.

The results of the running average value for THM’s for all related Distribution System samples in 2014

(Jan. 01 to Dec. 31) is below the ½ MAC (half of the maximum allowable concentration).

All operational Treated Sources were sampled and analyzed for Nitrates and Nitrites as per Regulation

170/03, Schedule 13-7. There was no instance of an adverse result in 2014. Raw sampling results are also

shown in Table 13 (ODWQS do not apply to these values).

In 2013, all operational “Treated Sources” were sampled and analyzed for Schedule 23 parameters as per

O. Reg. 170/03. All of the City of Guelph’s treated ground water sources are on a three year sampling

schedule. F.M. Woods’ Station is the exception and is sampled on the annual surface water schedule due

to the fact that three of the eight sources that supply F.M. Woods are GUDI-WEF sources (the Carter Well

field, Arkell 1 and the Arkell Glen Collectors).

The results of the Schedule 23 inorganic parameter analysis in 2013 were all under the ½ MAC (half of the

maximum allowable concentration) and the majority were under the laboratory’s MDL (minimum detection

level). Please refer to the section entitled “O. Reg. 170/03 Schedule 23 Results Summary” included in

Appendix “B” for more information.

The next scheduled “Three Year” Schedule 23 sampling event takes place in the third quarter of 2016.

The results of the Annual Schedule 23 inorganic parameter analysis in 2014 for F.M. Woods’ Station were

all under the ½ MAC (half of the maximum allowable concentration) and the majority were under the

laboratory’s MDL (minimum detection level).

reference.

In 2013, all “Treated Sources” were sampled and analyzed for Schedule 24 parameters as per O. Reg.

170/03. All of the City of Guelph’s treated ground water sources are on a three year sampling schedule.

F.M. Woods’ Station is the exception and is sampled on the annual surface water schedule due to the fact

that three of the eight sources that supply F.M. Woods’ are GUDI-WEF sources (the Carter Well field,

Arkell 1 and the Glen Collectors).

The results of the Schedule 24 organic parameter analysis in 2013 were all under the ½ MAC (half of the

maximum allowable concentration) and the majority were under the laboratory’s MDL (minimum detection

level). Please refer to the section entitled “O. Reg. 170/03 Schedule 24 Results Summary” included in

Appendix “B” for more information.

It should be noted that values for TCE (trichloroethylene) at Membro and Emma have on occasion, crested

the ½ MAC value of 0.0025 mg/L and as a result Water Services has moved to an “Increased Frequency

Sampling Plan” as required by Regulation 170/03 - 13-5 which requires that sampling for this parameter

be sampled every “three months” until two consecutive sample results are below the ½ MAC value. As a

precautionary measure, Water Services samples both raw and treated sources on a monthly schedule at

Membro and Water. All other sources, both raw and treated, are sampled annually (minimally) for VOC’s

(Volatile Organic Carbons) through a “Guelph VOC Scan” in order to better track parameters such as TCE

via more data. Currently, TCE is above the MDL but below the ½ MAC at Membro, Water Street, Park and

Paisley* POE.

*The TCE at Paisley POE can be attributed to Emma, Membro, Water Street and Park feed water via the

Paisley Reservoir low zone fill line as VOC analysis from 2007 to the present on Paisley raw water shows

values below the lab’s MDL (minimum detection level) for all parameters.

The next scheduled “Three Year” Schedule 24 sampling event takes place in 2016.

The results of the Annual Schedule 24 organic parameter analysis in 2014 for F.M. Woods’ Station were all

under the ½ MAC (half of the maximum allowable concentration) and the laboratory’s MDL (minimum

detection level).

reference.

In 2014, all operational “Treated Sources” were sampled and analyzed for the Schedule 13-9 Fluoride

parameter as per O. Reg. 170/03. In 2014, Fluoride (naturally present) was detected at all treated

sources; the analytical results were all under the MAC (maximum allowable concentration). The values in

Table 17 reflect the 2014, Schedule 13-9 sampling regime. Sodium, however, is sampled on a more

frequent basis (annually) than the Schedule 13-8 requirement. Due to the fact that at every treated

source with the exception of F.M. Woods (currently), sodium levels are above the lower reportable limit of

20 mg/L. The increased frequency of sampling provides more data in order to better establish sodium

value trends. Sodium results for 2014 can be referenced in “

inquiries from Water Services staff and consultants in terms of treatment upgrades et cetera.

Please note that Schedule 23 parameters are also part of the “Annual General Chemistry Sampling

Regime” and therefore the values in the “General Chemistry Results Summary” section in Appendix “B”

include a repetition of the relevant data from the Schedule 23 Table. The “General Chemistry Results

Summary” lists the total number of samples analyzed for these parameters in 2014.

In 2014, all operational “Treated Sources” were sampled and analyzed for general chemistry parameters.

Please refer to the “General Chemistry Results Summary” in Appendix “B” for the full list of parameters.

i) Treated Water Quality – Gazer Mooney Subdivision Distribution System

This section describes the Regulatory water quality monitoring that has been collected in the Gazer

Mooney Subdivision Distribution System in 2014 (Jan. 01 to Dec. 31, 2014). For regulatory sampling

schedules that do not occur in 2014 related to the Gazer Mooney System, the most recent historical data

is listed.

16 Where supplies contain naturally occurring fluoride at levels higher than 1.5 mg/L but less than 2.4 mg/L, the Ministry of Health

and Long Term Care recommends an approach through local boards of health to raise public and professional awareness to control

excessive exposure to fluoride from other sources.

Water Quality Review - Gazer Mooney Subdivision Distribution System

Under the Safe Drinking Water Act (SDWA), municipalities are required to monitor both the raw and

treated quality of the source water supplied. This monitoring is performed for both regulatory compliance

and due diligence and is expected to identify any changes within the treated water as well as in the raw

source waters.

A note about all tables included in this section:

1. All regulated chemical parameters where values above the lab’s MDL (minimum detection limit)

have been detected in the City of Guelph’s treated water sources are underlined indicating a

hyperlink to an Excel Workbook in Guelph’s EDMS (electronic document management system).

Note: EDMS is available for internal use only. The workbook contains a definition of the parameter,

an Excel worksheet for each treated source where the parameter has been detected with values for

all sample results from Jan. 01, 2007 to Dec. 31, 2014. This database is used to closely track the

instances of the identified chemical parameters and therefore provide time for planning / budgeting

if treatment or an alternative supply is eventually required due to the presence of a given

parameter. The database is updated quarterly.

2. Tabulated values are from best available information at the time of table creation. While the values

above satisfy the regulatory minimum regulatory requirements, Water Services performs many

additional operational tests not listed in this report.

3. All acronyms and initialisms included in tables are described in Appendix “E” – Index of Terms,

Acronyms and Initialisms.

The following section summarizes daily Distribution free chlorine residual test results required by O. Reg.

170/03 Schedule 7-2 for the period of Jan. 01 to Dec. 31, 2014. There was no instance of an adverse

Treated Water Quality Statistics – O. Reg. 170/03 Schedule 13-6, “Three Month” Sampling

Results Summary

In 2014, Gazer Mooney Subdivision Distribution System was sampled and analyzed for Schedule 13-6

parameters as per O. Reg. 170/03:

Regulation 170/03, Schedule 13-6 requires a minimum of one distribution sample taken from the

Distribution System where THM’s (trihalomethanes) are most likely to develop (points with high retention

times). The MAC for THM’s is 0.1 mg/L. However, for this parameter the MAC uses a running annual

average of quarterly samples.

The results of the running average for the Gazer Mooney Subdivision Distribution System samples in 2014

(Jan. 01 to Dec. 31) is below the ½ MAC (maximum allowable concentration).

j) Status of Ongoing and Emerging Water Quality, Supply and Distribution

Initiatives

This includes summaries and updates related to the implementation of the:

- Water Conservation and Efficiency Strategy & Water Supply Master Plan;

- Source Water Protection Plan; and

- Lead Reduction Plan.

Water Conservation and Efficiency Strategy & Water Supply Master Plan Updates

Water Services continues to implement recommendations of the 2009 Water Conservation and Efficiency

Strategy. The Water Conservation team produces an annual report on The Water Conservation & Efficiency

Program, and the last update, “2014 Annual Progress Report” is included in Appendix “D”. Below is a

summary of 2014 aspects of the Water Supply Master Plan that were implemented between Jan. 1 to

December 31, 2014 to support sustainable water resources management:

- The City of Guelph celebrated Canada Water Week with the second annual H2O GO Festival, a large

scale engaging celebration of water. Collaborating with community partners, H2O GO welcomed the

contributions of local businesses, community organizations, experts, performers and families. The

event attracted over 400 participants of all ages to City Hall for water-themed presentations, live

performances of music and dance, interactive exhibits, games about water and artistic children’s

activities. In addition to these initiatives, nine local water-themed public events were hosted

throughout the City during the month of March in support of Canada Water Week and World Water

Day. The festival was held on the same day as and within walking distance of two other

sustainability themed events, Guelph Environment Leadership’s EcoMarket and Transition Guelph’s

Resilience Festival. At all events, participants were encouraged to attend neighbouring events,






Page 33 of 77

thereby creating a festive spirit in the downtown core that achieved the goal of engaging the public

in learning about water in Guelph. In addition to these events, Water Services launched a week-

long social media engagement campaign about water protection, conservation and enjoyment

featuring items on the importance of the Grand River watershed to this region in accordance with

the week’s theme of “Watersheds 101”. Also part of Canada Water Week, the Guelph Public Library

and Guelph Water Services Department partnered to host ‘Water Wednesdays’ at two local library

branches. These events offered water-themed educational programming for all ages, including

interactive games and activities designed to inform local youth of Guelph’s water sources, steps

taken to treat our community’s drinking water, and the importance of conservation and protection

of our precious water resources.

- On June 9th, 2014, approximately 800 students from Guelph elementary schools participated in

H2Awesome, a day-long event celebrating water conservation and the importance of water in our

daily lives. The event featured well-known water advocates Alex and Tyler from The Water

Brothers, the TVO eco-adventure documentary series. Also key to the event was a variety of 17

different curriculum linked workshops on various themes, including arts, science, and technology,

enabling students to pick their own specific learning venue. The event was a successful

collaborative partnership project with the City of Guelph, Wellington Water Watchers, the Upper

Grand District School Board, and the University of Guelph.

- Review of City’s Outside Water Use By-law was completed in March 2014 with Guelph City Council’s

endorsement of the revised Outside Water Use By-law and associated program amendments.

Terms of the revised by-law came into effect on April 1, 2014. For more information on the revised

by-law and by-law review process please visit guelph.ca/owureview.

- Tender for the construction of the integration of rainwater harvesting within Guelph Transit’s bus

wash was completed in June 2014 with construction of process completed on October 8, 2014.

Through the integration and use of harvested rainwater for the final rinse phase of this process,

potable water and chemical wash needs are anticipated to be reduced by 40 per cent per bus. This

project is made possible through funding provided by the Province of Ontario’s Showcasing Water

Innovation Program.

- Field implementation of six district metered areas (DMAs) continued throughout early 2014 as part

of the City’s Leak Detection Program. These works, supported by the Province’s Showcasing Water

Innovation Program, will allow the City to proactively monitor and respond to leakage at the time

of leak occurrence in defined DMA locations, as well as retain on a ongoing basis water loss savings

previously reclaimed. In building upon these innovative works, detailed hydraulic modelling and

prioritization of an additional 21 DMAs was initiated in January of 2014 with these additional DMAs

to be implemented over the next 4 year period (2015-2018).

- Annual Leak Detection Program launched in August 2014 including sounding and correlation of all

metallic watermains within the City’s distribution system, encompassing 287km of linear

infrastructure. This study concluded in October 2014 with 3 watermain breaks of significance

identified through the study. Water savings following remediation of this infrastructure is

anticipated to be approximately 1,024 m3/day based on field water loss estimates.

http://www.guelph.ca/owureview


Page 34 of 77

- Operation and optimization of existing conservation programs continued (e.g. Residential Rebate

Programs, Blue Built Home, ICI Capacity Buyback Program), equalling 230 m3/day in collective

demand reductions in 2014.

Source Water Protection Plan

This section includes summaries on Guelph’s Source Water Protection Program initiatives and

ongoing work related to preparation for implementation.

The Lake Erie Source Protection Committee submitted the Proposed Grand River Source Protection Plan

to the Ministry of the Environment and Climate Change (MOECC) for review and approval. This Plan

includes a number of proposed policies to manage significant drinking water threats (identified in the

Assessment Report) for the City of Guelph. The MOECC is presently reviewing Source Protection Plans

that have been submitted from across the province. The Lake Erie Source Protection Committee

anticipates that the Grand River Source Protection Plan will be approved by the Minister in 2016.

Currently, City staff are working on: the development of education and outreach materials for

stakeholders, development of guidelines for the preparation of risk management plans, and working

with internal City of Guelph departments to ensure conformance with the proposed policies in the

Source Protection Plan. The City is also assessing the data management and information needs that

will be required to administer the program once the Source Protection Plan is approved.

For more information on Guelph’s Source Water Protection Program visit: guelph.ca/sourcewater

Arkell Springs Forest Stewardship Project

The Arkell Spring Grounds cover an area of 804 acres. The area is comprised of old and new forested

areas, which makes it necessary for monitoring, maintenance and new planting plans. The objective of the

Arkell Springs Forest Stewardship Project is to manage past plantings and prevent losses while monitoring

general forest health. Delicate forest stands require continued maintenance and observation to ensure the

prevention of any unnecessary and undesired losses.

Since 2007, the Community Environmental Leadership Program (CELP), on a volunteer basis has planted

16,500 trees on 18 acres, and Bartram Woodlands (on-site contractor) has planted 21,200 trees on

another 16 acres. In addition, funding was secured through the Ontario Ministry of Natural Resources’ 50

Million Tree Program—part of the United Nations Billion Tree Campaign. The Ontario portion of the fund is

committed to planting 50 million trees by 2025. This funding allowed the City to plant 5,245 seedlings in

fields adjacent to Watson Road.

The many benefits of the Arkell Springs Forest Stewardship Project include the creation of a diverse and

functioning forest cover, maintenance and re-generation of older forested areas on the property,

protection and recharge of underground aquifers, prevention of undesirable surface water runoff and

flooding into local waterways, and regulation of the flow of water.

The characteristically strong organic matter component of soils within a forest allows for added infiltration

and precipitation to recharge the underlying aquifer. The filtration ability of a forest system results in

additional methods to filter water.


Page 35 of 77

This multiple barrier approach results in the highest possible quality of water to supply Guelph’s drinking

water system. Forest systems also extend the longevity of the existing snow pack by stabilizing the

temperature of the ground and limiting the evaporative impact of the sun. This ensures water resources

are re-absorbed into the underlying aquifer where they are needed rather than contributing to damaging

runoff and flooding.

Lead Reduction Plan

The City submitted a Lead Reduction Plan (LRP) to the MOECC in April 2011 as a result of two rounds of

legislated lead sampling indicating that more than ten percent of residential samples taken exceeded the

ODWQS of 10 μg/L. The LRP was submitted in lieu of a Corrosion Control Plan (as outlined in O.Reg

170/03 Sched. 15) after evaluation of both chemical corrosion control and physical replacement, as well

as extensive consultation with the MOECC, and Wellington-Dufferin-Guelph Public Health. The MOECC

formally approved the City of Guelph’s LRP and application for full regulatory relief from the lead sampling

requirements of Schedule 15.1 on March 21, 2012.

In January 2014, based on the success of the program, the City formally requested an amendment to the

City’s Drinking Water Licence to remove the references to the regulatory requirements and reporting

associated with the City’s lead program. Lead service line replacements have permanently reduced the

number of homes exceeding the ODWQS for lead to below the Schedule 15.1 regulations. Regulatory relief

from Schedule 15.1 (in its entirety) in exchange for the continued operational programs outlined in the

LRP, was granted in Schedule D of the City’s Municipal Drinking Water Licence issue number 6.

This section provides a summary of the aspects of the LRP.

The following table presents summary results for lead sampling in the Guelph Drinking Water System as

per our Lead Reduction Plan for the period of Jan. 1 to Dec. 31, 2014:

Lead Sampling

Lead sampling is conducted to identify the presence of lead service lines (LSL) and to monitor lead levels

following a LSL replacement. For the period of Jan. 1 to Dec. 31, 2014, 89 Lead Verification samples were

taken. Of these sample results, 6.7% were above 5 µg/L indicating presence of a lead service line. Of all

verification samples, 5.6% also exceeded the ODWQS of 10 µg/L. Lead samples are collected before and

after a LSL replacement has been undertaken. There were 18 resamples collected in order to monitor lead

levels post-replacement. Based on sample results to date, regulatory compliance is expected at individual

sites that have undergone a full LSL replacement or where there is no lead remaining in the service line.

Lead Service Line Replacements

There were 11 Lead Service Line (LSL) replacements undertaken in the City between Jan. 1 to Dec. 31,

2014. These replacements include the following situations: i) Full LSL Replacement where both the City-

and private-side of the LSL is replaced, ii) Partial LSL Replacement where only the City-side of the service

is replaced and connected back to lead or a non-lead material on the private-side, and iii) Private LSL

Replacement where the private-side of the service is replaced and the City-side is known to be copper.

The next table presents a summary of all LSL replacements in the Guelph Drinking Water system for 2014

up to Dec. 31.

22 The LSL Replacement Grant Program provides eligible property owners funding to off-set the cost of replacing an LSL on private

property.

23LSLs are replaced when discovered during planned street reconstruction activities.


Page 37 of 77

Privately Owned Lead Service Line Replacements

Since 2010, the City initiated has been providing two financial incentive programs to encourage

replacement of privately-owned LSL by reducing the financial burden to property owners. The grants cover

70 to 100 percent of the LSL replacement cost for homeowners. The Private Lead Water Service

Replacement Grant Program provides funding to homeowners to replace a confirmed privately owned LSL

where the City-owned water service line is confirmed to be copper (i.e., City-side LSL was previously

replaced). The Full Lead Water Service Replacement Grant Program provides funding to homeowners to

replace a confirmed privately owned LSL in tandem with City-owned LSL replacement. From 2010 to Dec.

31, 2014, 185 privately owned lead service lines were replaced through the grant programs.

Yearly Total 60 63 30 21 8

Grand Total to date - - - - 185

Targeted outreach regarding the Grant Programs is directed at all properties with known or suspected

privately-owned LSLs. The main barriers to privately owned LSL replacement for homeowners include

financial costs, disruption to property, and people who are unconcerned about the health risks of lead in

drinking water. Direct communications continued to be been tailored to address these barriers.

Encouraging replacement of privately-owned LSL by rental properties was identified as a significant

challenge for the Grant Programs. The City is not able to provide grant funding to commercial entities due

to the “bonusing” restrictions of the Municipal Act. In April 2012, changes were made to the Grant

Programs to allow rental properties that are not owned by a commercial enterprise (including property

management enterprises) to apply for a grant in accordance to the Municipal Act. Targeted communication

to property owners regarding this change has successfully increased uptake in the Grant Programs.

Correspondence with the MOECC regarding the finalization of the updated Municipal Drinking Water

Licence and Drinking Water Works Permit took place over June and July, 2014. Final documents were

issued in August (MDWL) and September (DWWP) and expire in 2019.

Operational Testing Plan and Adaptive Management Plan (OTP / AMP)

The purpose of the OTP / AMP is to carry-out a detailed assessment of both the Arkell area aquifer and

pumping conditions related to the aquifer to determine a sustainable capacity with respect to

environmental considerations in the area. It is anticipated that the OTP / AMP will take place over

approximately three years. Additional details may be obtained by contacting Water Services. Annual

monitoring reports providing reporting on monitoring results for the previous year were provided in early

2012 and early 2013. As a result of two years of monitoring, Water Services requested an increase to the

Arkell Bedrock Wellfield Permit to Take Water which was granted by the MOE in October 2013. Water

Services is continuing to assess the sustainability of the bedrock water taking at the higher pumping rates

with the intention of modifying the monitoring requirements within the permit. Additional monitoring and

data collection / assessment is ongoing, and further extensive monitoring is being performed at Arkell Well

#15 to confirm its source water characteristic classification as groundwater.

GUDI (Groundwater Under the Direct Influence of surface water) Terms of Reference are under

review and may result in classification changes to source waters. The GUDI Terms of Reference are

expected in 2016.

Carter Monitoring Program

The Permit to Take Water for Carter Well requires that the Carter Wells be operated at increased levels in

conjunction with monitoring in the Torrence Creek Subwatershed. The purpose of the monitoring is to

attempt to quantify impacts within this subwatershed.

Water Supply Master Plan

Council unanimously voted to approve an update to the City’s 2007 Water Supply Master Plan on July

28th, 2014. This update forecasts and makes plans for water use and access to a safe and sustainable

water supply for our growing community—residential, industrial and commercial—over the next 25 years.

The Water Supply Master Plan update process involved extensive public consultation, input from a

Community Liaison Community, and feedback from agency representatives and local municipalities. The

update process also included a 30–day review period during which interested parties were invited to

provide comments and ask questions.

Conservation and demand management remain the key options for meeting our current and future water

supply needs, with new groundwater supplies from existing, offline wells, test wells and new wells inside

the city limits also helping to meet future needs. Other recommendations and options include

improvements to the water planning and approval process, a by-law to restrict new private groundwater

supply wells within the City limits, and a possible future treatment plant for a surface water supply from

Guelph Lake.

n) The Results of Infrastructure Review

The review of infrastructure requirements is achieved by reviewing the needs of existing infrastructure and

of new infrastructure requirements. This review is carried out for the infrastructure needs of distribution

and supply & facilities.

Distribution Infrastructure Needs

On a regular basis (at monthly meetings), Guelph’s Engineering and Water Services review the condition

of supply and distribution infrastructure and review: inventory, age, CAPS (capital asset prioritization

system), criticality, soil type and diameter. From this evaluation, Engineering and Water Services develop

a list of priority projects that also considers the priorities of wastewater and road reconstruction projects

so that these projects can share the costs of excavation and rehabilitation. The priority list is updated

(with considerations included) and presented in Annual Operating Budget and the Tri-Annual Capital

Budget processes. New linear infrastructure reviews are primarily driven by Engineering Services.

Annual summaries of road reconstruction, sewer and watermain projects are identified on an

infrastructure map that is released early spring each year.

An Asset Update Report was prepared in 2012 to rate sustainability for various infrastructure programs

across the City. Water Services’ sustainability rating is A-.

Supply & Facilities Infrastructure Needs

On July 28th, Guelph City Council unanimously approved the Water Supply Master Plan update (linked to

news and document on Guelph.ca). The Master Servicing Study is another infrastructure plan that is

updated every five years and is used to identify new and replacement infrastructure priorities to include in

the budgeting process. The development of a Facility Master Plan is also in progress, along with new

initiatives related to property planning for expansions of facilities or to implement new facilities, as

required. The Owner (Council, CAO and Deputy CAO) is updated regarding any deficiencies or gaps.

Backflow Prevention Program

Preservation of drinking water quality within Guelph’s infrastructure is supported by the City of Guelph’s

Building Services and Guelph’s Backflow Prevention Regulations (“By-law”, Number (2008) – 18660). As

per the By-law, “Backflow” means the flowing back of or reversal of the normal direction of flow of water.

The By-law requires that no connections are made to the City’s water supply without the installation of a

backflow prevention device to isolate premises, sources, and zones to prevent cross-connections in every

building or structure where a City water supply or other potable water supply exists.

On a regular basis, Building Services provides the following “Backflow Report” included in the table below

that tracks the number of letters sent out regarding annual testing and re-surveying requirements of the

By-law.

The City of Guelph has a total of 2,652 properties (2,574 active and 78 inactive properties) that have a

total of 6,149 backflow prevention devices installed. Of the total, 1,860 buildings have premise isolation

and 944 buildings are without premise isolation (e.g. residential irrigation systems, plaza facility – plaza

Table 33: Improvement Actions Summary

OFI # Suggestion Title Improvement Action Description

14-01 New SCADA Operator duties The new SCADA Operator role was created to improve efficiencies in data

review. Supply Operators will be rotated into this position on a monthly basis.

14-02 Improvements to Supply’s 2014

Work Orders

Supply facilities are now task-based so that these designations remain the same

from year to year and the type of work is designated with the Work Order #.

Maintenance work orders now have four subcategories: emergency, urgent,

corrective and preventive. New tasks include Water Quality Monitoring for

SCADA Operator and for Non-Compliance Investigative Sampling. Operator-

based Operations Maintenance is a new work order added.

14-03

Installation of Pressure Reducing

Valve at Paisley Well for

Queensdale Subdivision isolation

Installed a Pressure Reducing Valve at Paisley Well so that the Queensdale

Subdivision could be isolated to allow for a watermain repair on a transmission

main.

14-04 Improved Snow Clearing at

Arkell with McKenzie Bros.

Contacted McKenzie Brothers to assist with large amount of snow clearing at

Arkell Spring Grounds.

14-05 Improved Meter Inventory

Tracking

A new sign-out program exists for improved tracking of the meter inventory.

The name, date and meter serial number is tracked; and meter installation

sheets are now submitted through the Water Distribution Technician.

14-06

Returned Speedvale Tower PLC

and heater to station power and

replaced unreliable UPS

The Speedvale Tower PLC and heater was returned to station power to prevent

communications to fail repeatedly. The unreliable UPS was also replaced in the

PLC cabinet.

14-07 Improved “Source and

Distribution Sampling Procedure”

The “Source and Distribution Sampling Procedure” was improved to include

three new elements: 1. Nitrile gloves while handling sample bottles and during

the sampling process; 2. Place the necessary empty sample bottles for the

sampling event (including a few extra) in plastic re-sealable zipper storage bags

within an appropriately sized cooler; 3. When a station POE Booster Pump must

be started prior to sampling, allow to run for a minimum of one hour before a

sample(s) is taken.

14-08 Improved University Setpoints

Since University’s contribution to overall volume and pressure is more relevant

at night, University’s fill and draw time cycles will be run in reverse at night.

This will help optimise the low zone performance overnight and keep Burke’s

station off.

14-09 Distribution Map Book in PDF

The Water Distribution Technician has created (in PDF) an electronically

searchable distribution map book. A new grid now exists so that all pages are

the same scale and at a scale that is easier to read than the previous books. On

the first page (of 195 pages) is the index map. Clicking on a grid on this page

will take you to that map page. In the bottom-right corner of each map page, is

a link to the “Index Map” on the first page.

14-10 Increased response to “Frozen

Services”

With the increase in frozen services this past winter (due to extreme cold

leading to deeper than average frost depth), staff spent considerable time

investigating frozen services, thawing service lines or installing temporary water

services where possible. A web page dedicated to answering frequently asked

questions was also developed.

14-11

New logsheet in Facility

Logbooks to document quarterly

verifications of facility

colorimeters.

A new logsheet exists in the Facility Logbooks to document the quarterly

verification of facility colorimeters. The Water Services Master Logbook has a

similar section for Operators’ Colorimeter reference checks – these checks are

performed by the owners of the individual Colorimeters. Entries for three

http://guelph.ca/living/environment/water/drinking-water/frozen-water-service/


Page 50 of 77


quarters are provided for in the Logbook and the fourth quarter is covered by

the Annual Calibration schedule.

14-12

Paisley Well Operations &

Maintenance Manual clarification

re: pump run combinations; and

SCADA logic also updated.

Clarified the maximum number of Pumps/Combinations at Paisley Well so as not

to exceed the power draw that trips the 400 amp breaker that feeds all of the

Booster Pumps (1, 2, 3, 4, 5, 6 and 7) and the Well Pump; as well as the

maximum number of Pumps/Combinations with the Well Pump off. Also, the

auto logic was updated in SCADA so that when running Vertical Turbine Pumps

in Auto, duty pump 4 will no longer start – in order to meet electrical code legal

requirements.

14-13 Clarification of Well Minimum

Pumping Levels

Operations and Maintenance Manual sections that refer to the MPLs (Minimum

Pumping Levels) at a given site have been replaced by the Operators to reflect

the standard ‘3 metres above pump inlet’.

There are some Logbooks where the MPL is referenced on each page of the

‘Weekly P.M. Data Sheet’ – the Logbook electronic files were updated to reflect

the changes.

14-14

Various upgrades towards

possibility for Zone 2 “Closed

Pressure System”

Various upgrades towards implementation of the Zone 2 “Closed Pressure

System” includes installation of new equipment; diesel generators’ automatic

transfer switches wired and tested; training; pressure monitoring through

installation of data loggers at hydrants; and replacement of valves at Robertson

Booster Station inlet and point-of-entry. A draft control narrative for Paisley and

Robertson under a Zone 2 Closed Pressure System is also proposed.

14-15 Larger network cabinet

implemented

In order to accommodate growing computer & networking needs, the IT

department removed the main network cabinet from the Library to a new larger

network cabinet in the SCADA server room.

14-16 eRIS SCADA upgrade to new 1.2

release

New features in the 1.2 release are:

Upgraded Data Query tag selection interface

Upgraded Data Query Charts with new selection features and zoom

capabilities

Upgraded Calculation interface with easier user ability

New eRIS support forum with embedded access in eRIS

14-17 Manual Booster Operation on

Station Re-start Checklist

The ‘Manual Booster Operation Re-start Checklist’ was created to cover all the

compliance procedures and necessary documentation required to bring a Facility

back on-line after the following:

1. Post Auto Low Chlorine Shutdown Condition.

2. Facility off-line resulting in non-representative values @ Analyzer

14-18 Water Meter Testing Pilot Installed a meter testing station at Water Services for a demonstration project

that the metering group is developing.

14-19 Expansion of the Rainwater

Harvesting Rebate Program

The Rainwater Harvesting Rebate Program now offers two different rebates:

1) Seasonal outdoor system: Install an approved rainwater harvesting

seasonal tank and receive a one–time rebate of $0.10/litre of tank storage

(to a maximum of $400); or

2) All–season indoor/outdoor system: Install an approved all–season

rainwater harvesting system and receive a $2,000 rebate.

14-20 Improved process for Operator

comments regarding alarms

The SCADA Operator now completes the twice daily eRIS Facility Trend

Reviews; and alarm comments can be limited to “reportable” or “non-

reportable” with an indication as to where more information can be found.

14-21 Increased Emma’s VOC

Sampling Schedule to Quarterly

In response to Emma reaching ½ MAC (half of maximum allowable

concentration) for VOC’s, the related sampling schedule has been increased to

quarterly.

14-22

Updated Supply Processes using

manufacturer instructions to

include new MDWL UV

requirements.

Updated Supply Processes using manufacturer instructions, to include new

requirement in the Municipal Drinking Water Licence (MDWL) related to tracking

UV lamp hours so that “…continuous pass-through UV dose is maintained

throughout the lifetime of the UV lamps…” Trojan recommends UV sensor

verification on a monthly basis and re-calibration of the reference sensor every


Page 51 of 77


three years (however, more stringent requirement of annually is required by the

MDWL).

14-23 New Security System at all

Water Services Sites

New security system is implemented to keep buildings, equipment and water

supply and treatment system safe. By-law will be able to monitor the cameras

remotely 24/7 as they already do for many other satellite sites throughout the

City to help keep us secure and aware of intruders. Certain staff will also be

able to monitor our cameras from here ourselves. Camera recording usage and

data retention time will remain consistent with City policy.

14-24 Arkell Well Houses Inspected

and Repaired for Safety Issues

Found snakes’ points of entry at Arkell Well Houses (e.g. #1, #6, #15) and

repaired (filled with foam) to prevent re-entry.

14-25 Chemical-resistant (e.g. Viton)

gaskets, o-rings, etc. installed

Outlet four-bolt flanges plumbed in sodium hypochlorite storage tanks leaked

when the gaskets (that were evidently not chemical-resistant) broke down. The

leaking gaskets were replaced with a chemical resistant product (e.g. Viton) to

prevent future leaks. Future replacements of gaskets and o-rings will be of a

chemical-resistant nature (e.g. Viton) when they’re interacting with chemicals.

14-26

Numbered fire extinguishers to

better track monthly fire

extinguisher inspections

All fire extinguishers now have a numbered identifier. Floor plans are updated

with the location of each numbered extinguisher. The information is also

organized with extinguisher numbers by building location to facilitate inspection.

14-27 Paisley monitoring screen

updates

Paisley screen updated to show inlet valves Local/Remote status on the main

screen. Also cleaned up some font sizes.

14-28

Zone 2 closed pressure system

tested & work instructions

developed

Tested new equipment and programming associated with the ‘Zone 2 Closed

Pressure System’. The two testing periods (one evening and one weekend)

confirmed that Zone 2 could be successfully run as a closed pressure system.

14-29 Verney Tower cable restraint

system inspection

Unistrut performed the inspection of the cable restraint system at Verney

Tower.

q) New or Other Business

This section provides an update on new or other items of business beyond the scope of this report.

r) Next Meeting Dates

The next Management Review Meetings scheduled to review the updated Annual & Summary Water

Services Reports are scheduled for September 2015 and January 2016.

Appendix “C” – Total Water Pumped and Instantaneous Flows

Note on Capacity:

Capacity is calculated by comparing the average pumped or flow value against the MDWL allowable

volume or PTTW flow. Capacity is representative of the conditions of pumping for that year which may be

influenced by other testing programs, maintenance or special operational conditions. Additionally, the

actual capacity of the source may not be achievable with current infrastructure. Optimization efforts are

included as a component of the Water Supply Master Plan with the intent to match the actual capacity of

the water source with the appropriate infrastructure.

Appendix “D” – Water Conservation & Efficiency Program – 2014 Annual

Progress Report (updated annually)

Background:

The City of Guelph strives to be a leader in water conservation and efficiency. As one of Canada’s largest

communities reliant on a finite groundwater source, our ability to reclaim precious water capacity through

conservation initiatives offers numerous benefits to our community and local ecosystem.

In 2006 City Council endorsed the Water Supply Master Plan (WSMP). This detailed Master Plan evaluated

the water demand associated with projected growth over a 50 year planning horizon, as well as alternative

sources of new water supply. Water conservation was identified as the most cost-effective and

immediately available source of new water supply and was ranked as the top priority. The WSMP included

three reduction targets based on 2006 daily water production volumes:

Reduction of 10 per cent (5,300 m3/day) in average day water use by 2010;

Reduction of 15 per cent (7,950 m3/day) in average day water use by 2017; and

Reduction of 20 per cent (10,600 m3/day) in average day water use by 2025

Both the 2007 Community Energy Initiative and the 2007 Council Strategic Plan set sustainability

performance goals of using “less water and energy per capita than any comparable Canadian city.” These

goals continue to guide our current water conservation activities and bring greater emphasis to the

relationship between water supply and energy demand.

To achieve these targets, staff initiated the Water Conservation and Efficiency Strategy (WCES) Update in

February of 2008. This award winning, 10-year strategy was endorsed by Council in May 2009 and

identifies the preferred program, policy and resource recommendations to achieve a further reduction of

8,773 m3/day by 2019, as well as to achieve the aggressive reduction targets of the Water Supply Master

Plan, Water and Wastewater Master Servicing Study, Wastewater Treatment Master Plan, Community

Energy Initiative, and Council's Strategic Plan.

Since Council’s approval of the 2006 Water Supply Master Plan, 7,116 m3/day of average day

water/wastewater capacity has been reclaimed as a result of the City’s Water Conservation Program,

allowing the City to delay the need for close to $35.6 million in additional water and wastewater

infrastructure with an investment of approximately $8.6 million in water conservation programming.

In addition, since 2001 when the City’s Outside Water Use Program was first implemented, the community

has reduced our annual peak day water use (i.e. the highest daily demand for water each year) by over

21,200 m3/day, thus reducing infrastructure required to meet peak demand which is experienced on only

a few days each year.

Furthermore, water conservation has led to a reduction in the amount of electricity and water treatment

chemicals used to treat and convey water and wastewater. This results in an annual operational savings of

over $470,000 per year, creating a significant financial benefit to our rate payers. As a result of such

efforts, the City’s water and wastewater rates remain much lower (within the 50th percentile) than that of

many comparable Ontario and local municipalities.

2014 Progress Overview

The following sections provide an overview of Water Conservation and Efficiency Program activities

undertaken in 2014. For more information on individual programs or initiatives please visit:

guelph.ca/ourstoconserve.

1. Leak Detection Program

The City’s leak detection program aims to reduce the amount of water lost between the time of

production and end delivery to customers. In 2014 the program included the evaluation of 287 km

of the City’s linear watermain infrastructure through use of sounding and correlation technologies.

In total 3 watermain breaks of significance and number of distribution maintenance

recommendations were identified through the study with approximately 1024 m3/day in water

production capacity anticipated to be reclaimed as a result of remediation of watermain breaks

discovered.

The 2014 Leak Detection Program also included the continued introduction of district metered areas

(DMA) within six separate locations of the Guelph water distribution system as well as ongoing

monitoring of the City’s first DMA in the Woodland Glen neighbourhood on Stone Rd West. Through

employment of this industry best practice for water loss management, a permanent underground

flow meter(s) and chamber(s) are installed in parallel with isolation of an area of the water

distribution system to allow water use in this area to be monitored through a single or multiple

metered watermain feed, on a continuous basis. This approach to water loss mitigation will allow

staff to define the normal profile of efficient water delivery for defined areas of the water

distribution system and provide a baseline to evaluate future demands against, so to assess the

occurrence of potential leakage within the area. As an innovative feature of the City’s field

implementation of DMAs, field information from each flow meter will be transmitted via cellular

network to the City’s SCADA system where information will be logged and flows assessed versus

established control limits to define the occurrence of previously unknown leaks in areas of the

distribution system. This approach to water loss management is anticipated to allow for the

proactive response to distribution system leaks and support the retention of water savings already

reclaimed from prior leakage restoration.

Resources for implementation of DMAs in 2014, and associated water and energy distribution

optimization activities, were graciously provided by the Province of Ontario’s Showcasing Water

Innovation Program. In recognition of benefits offered through this proactive water loss

management approach, Guelph Water Services will be working to implement an additional 21 DMAs

over the period of 2015 to 2018 with funding provided through local development charges and local

user rates, with the intent of reclaiming 1.5 MLD (approximately 3.3 per cent on 2015 daily system

input volume) in water servicing capacity by 2019.

2. Residential Water Conservation Rebate Programs

During 2014, a total number of 2,086 rebate applications were processed via the City’s residential

rebate programs. The majority of rebates claimed continue to be based in the City’s Royal Flush

Toilet Rebate and Smart Wash Clothes Washer Rebate Programs, with a limited amount through


Page 68 of 77

the Home Humidifier Rebate Program. In total, approximately 230 m3/day of reclaimed water

savings is anticipated as a result of residential rebate program participation in 2014.

Further to routine promotion of the City’s water conservation retrofit programs, Water Services also

initiated customized engagement of the local business sectors in 2014 to increase awareness of

program resources and potential water use efficiencies specific to the sector. This included a multi-

residential marketing campaign for building owners comparing individual building unit water

consumption to multi–residential sector averages, as well as anticipated utility savings and return

on investment for buildings pursuing mass retrofit of inefficient toilets. Staff also initiated an

engagement campaign of local restaurants promoting efficiency opportunities to reduce operational

costs while enhancing the experience of patrons. Staff plan to further build upon these engagement

campaigns in 2015 as well as seek other ways to customize engagement to defined sectors

possessing water saving opportunities.

For more information on the City’s Water Conservation Rebate Programs please visit

guelph.ca/rebates.

3. Institutional, Commercial and Industrial (ICI) Water Capacity Buyback Program

Since introduction of the ICI Water Capacity Buyback Program in 2007, the City has reclaimed over

1,500 m3 per day in water/wastewater servicing capacity, while assisting local business to reduce

their environmental footprint and ongoing operational costs. This program offers financial

assistance to local business for the completion of detailed water efficiency process audits and

incentives towards capital retrofits which reduce water demand.

From 2007 through 2010, several of the City’s top water users had participated in this program,

but participation amongst business possessing a smaller water use footprint had been limited due

to investment required to undertake process audits and uncertainties of financial efficiencies to be

realized as result of participation. In recognition of these challenges, Water Services’ ICI Water

Efficiency Specialist continued work in 2014 to engage and support all members of the Guelph

business community. This resource offers the local business community engineering services in

conducting detailed preliminary water use audits with the intent of realizing potential efficiencies

and limiting financial risk to business due to program participation.

Through this program resource, five detailed facility audits were completed in 2014. Furthermore,

2014 also saw the benefit of relationships built through the tenure of the program with local

businesses returning to the program to seek support to implement further site–based efficiencies

and inform process decisions. This included water efficiency capital retrofits implemented by the

University of Guelph and Blount Canada accounting for a total of 227 m3/day in observed water use

reduction.

4. Civic Facility Water Efficiency Upgrades

With the objective of leading by example through the City’s own operations, work in support of City

operational improvements continued throughout 2014.

Most notably, construction of a rainwater harvesting system to supplement the final wash phase of

Guelph Transit’s Bus Wash was completed on October 8, 2014. Since implementation,


Page 69 of 77

approximately 110 m3 of City water has been offset with rainwater, and installation of high-

efficiency nozzles has decreased bus wash water consumption by an estimated 456 m3/year. By

offset of this final wash phase, it is hoped that wash water and chemical use can be reduced by 40

per cent – a savings of approximately $7,000 per year to the Transit Utility. This project was made

possible thanks to funding provided by the Province of Ontario’s Showcasing Water Innovation

Program.

Further to the above, detailed water use audits of sixteen of the City’s highest water-using facilities

were initiated in 2014 as part of preliminary works for update of the City’s 2009 Water

Conservation and Efficiency Strategy. These works and small scale facility technology efficiency

trials are currently ongoing at this time with a report summarizing findings and estimated potential

savings anticipated for release in Q2 2015.

5. eMERGE Home Visit and Audit Service Program Update

eMERGE Guelph is an innovative collaboration between the City of Guelph, Guelph Hydro Electric

Systems Inc., Union Gas, Transition Guelph, Elora Environment Centre, and other local partners.

Building on the success of the Efficient Home Visit pilot program that ended in March 2012, the

eMERGE–led home visit service has expanded into a unique collaboration to help homeowners

achieve energy, water and waste reductions while enhancing transportation and food choices, and

inspiring green renovations in and around the home. The focus is on empowering citizens,

connecting neighbourhoods and transforming community toward a net zero environmental impact

in energy, carbon, water and waste.

The eMERGE Guelph Efficient Home Visit service continued with great success in 2014. This service

offers a free 45–minute home audit by trained advisors, a complimentary retrofit of common home

water use fixtures (such as water efficient showerheads and faucet aerators), and the development

of a household–specific action plan, providing information to residents on how to further reduce

home resource use and directing homeowners to further resources and tools to assist with the

implementation of recommended improvements.

This program, recommended through the Council approved 2009 Water Conservation and Efficiency

Strategy, is available to all residential households in the City of Guelph with utility servicing from

Guelph Hydro Electric System Inc., Union Gas and the City; the program has a base goal of

completing 900 home audits by December 31, 2015. For more information please visit

6. Blue Built Home Water Efficiency Standards and Rebate Program

Endorsed by City Council in November 2010, the Blue Built Home Water Efficiency Standards and

Rebate Program is a voluntary construction standard designed to outperform the plumbing and

water–using fixture requirements of the Ontario Building Code. This certification program for new

homes uses an approved set of high-quality home fixtures and appliances designed and third-party

tested to save water and reduce water and wastewater utility bills by 15 to 62 per cent. Blue Built

Homes are certified according to three water efficiency standards—Bronze, Silver or Gold—and

provide home buyers with a one-time rebate on their investment.


Page 70 of 77

Since launch of the program, a total of 29 new homes have been certified (27 Bronze, two Silver).

Of these, one Blue Built Bronze home, constructed by Habitat for Humanity was certified in year,

with construction of additional 22 Blue Built Homes initiating by TerraView Homes in mid-2014.

To evaluate the impact of this building standard, water use datalogging at each Blue Built Home

took place through the use of radio–read flexible axis water meters. This data logging wrapped up

in May of 2013, after the majority of the homes were monitored for one full year. The evaluation of

water use in Blue Built Home Bronze homes, completed in 2014, has demonstrated an average

savings of 33.56 m3/year for a family of three persons compared to a standard home built

according to the 1996 Ontario Building Code (191.2 m3/year).

In 2014 work began to incorporate the Blue Built Home program into Planning Services processes.

In September 2014 planners began informing builders and developers of the program during their

pre-consultation meetings. Steps are being taken to incorporate the Blue Built Home program into

the Planning group’s pre-consultation document, and Sustainability Check-list.

7. Youth Education

The City’s curriculum based, Grade 2 and Grade 8 in–class water conservation programming

continues to be a popular resource for local educators in both the Upper Grand District School

Board (UGDSB) and the Wellington Catholic District School Board (WCDSB), encompassing 52

interactive school presentations to 2,512 students conducted in 2014. Overall since the inception of

this water conservation educational initiative four years ago, the City has provided a total of 214

school presentations to over 7,000 students.

Furthermore, in partnership with the Grand River Conservation Authority’s Guelph Lake Nature

Centre, a total of 758 local Grades 7, 8 and high school students, as well as volunteers,

participated in guided educational tours of the City’s Water Services facility in 2014. These

interactive tours lead students through the processes involved in supplying, treating, and

distributing the City’s drinking water, as well as educating participants about the importance of

water conservation and source water protection as an essential part of ensuring the sustainability

of our City’s water resources.

Beyond City–led programming, Water Services is proud to be an ongoing partner, sponsor and

contributor to the Waterloo Wellington Children’s Groundwater Festival. This long–standing festival

celebrated its 19th year 2014. The Festival annually educates more than 4,000 grade two through

five Guelph, Wellington County and Region of Waterloo students. Since 1996, over 80,000 students

have participated in the Festival which features fun and interactive activities designed to inform

students of the importance of water protection and conservation in their daily lives. In partnership

with the Upper Grand District and Wellington Catholic School Boards, staff have worked to increase

local awareness and participation in this Festival with upwards of 800 Guelph–based students now

participating in the event on an annual basis.

8. Canada Water Week

Canada Water Week, a national, week-long celebration of water, is held annually during the third

week of March to coincide with World Water Day on March 22. In 2014, Canada Water Week was

held March 16th to 22nd with the theme: “Watersheds 101.”

2014 marked the City’s third year of participation in Canada Water Week programming with a

number of activities offered locally including a speaker’s event, March’s Water Wednesdays family

education programming at a variety of library locations throughout the City, a school art project,

and the second H2O Go! Festival at City Hall. The second annual H2O Go! Festival, a one-day event

to celebrate water, attracted over 400 participants again this year. In total, this successful event

featured workshops, information sessions, community booths, performances by local artists and

interactive children’s activities celebrating the protection, conservation and stewardship of our

precious water resources.

9. Peak Season Water Demand Management

Reduction of peak season water demands continue to be a primary objective of the City’s Water

Conservation programming. The ability to reduce variations in seasonal water use limits impacts on

our finite groundwater supply during times of environmental stress and creates operational

efficiencies by reducing capital and operational investment to service our community for only a few

days a year. Since 2002, the City’s Outside Water Use Program has helped to manage peak season

water use via regulatory controls with complementary programs, such as Healthy Landscapes,

working to proactively manage potential peak demands by assisting residents and local businesses

in establishing low outdoor water use environments.

Following 2013, a season of above average precipitation and consistent river levels within the

watershed, the City’s Outside Water Use Program remained at Level 0 Blue throughout 2014 due

significant seasonal precipitation, low temperatures, stable water flows throughout the watershed,

and overall community compliance with program terms.

In response to stakeholder concerns received through implementation of Level 2 Red water use

restrictions during the prolonged drought periods of 2012, Water Services initiated a review of the

Outside Water By-law in January 2013. This multi-phase project, designed in accordance with the

City’s Community Engagement Framework, engaged residents and local stakeholders in an

interactive dialogue on potential changes to the program and by-law. In concert with this public by-

law review process, staff also initiated an internal, multi-departmental Municipal Drought Response

Working Group to evaluate corporate peak season water use and to define protocols for response of

municipal operations during low water conditions.

In February 2014 Guelph City Council approved the revised Outside Water Use By-law. The revised

By-law and associated program changes came into effect on April 1, 2014. Following the

implementation of the revised By-law, new road sign info graphics were created, emphasizing the

permissions and restrictions for the most common outside water uses during the current program

level: lawn, garden and tree watering, and at–home car washing. Furthermore, based on

recommendations of the review, staff had worked to amend the City’s Rainwater Harvesting Rebate

http://www.canadawaterweek.ca/


Page 72 of 77

Program to create an individual program stream for seasonal rainwater harvesting systems, which

was launched to the public on May 1, 2015. More information on this new program resource can be

found at www.guelph.ca/rainwater.

In working to proactively manage peak season demand, the Healthy Landscapes Program offered

various public resources throughout 2014. The annual Healthy Landscapes Workshop/Seminar

Series featured numerous free talks on time–of–year appropriate outdoor water conservation topics

including water efficient landscape design, plant selection, and proactive maintenance best

practices to manage the impact of drought and common turf pests.

In addition, a Water Services’ Open House, rain barrel truckload sale, and plant sale was organized

in May of 2014 with over 500 rain barrels sold as part of the one day event. Rain barrels offer

homeowners the benefit of capturing free volumes of water for outside use but also assist in

managing stormwater impacts on private property. The sale of rain barrels are a net zero service to

the City as the barrels are sold at the bulk rate attained through an annual rain barrel tender

process.

Further to the above, the Healthy Landscapes assessment program continues to be a popular

resource with 252 visits completed in 2014. This service offers a complementary site–based

consultation aiming to educate residents on garden design and maintenance practices to

significantly curb outdoor demand at their home. Water efficiency studies completed in other

Ontario communities have shown a net result of 74 litres per day per household during peak

season as a result of similar water efficiency–based landscape consultant services.

10. Water Conservation Web Portal

In alignment with open government objectives of Council’s 2012 Strategic Plan, Water Services

initiated discussions in early 2014 with the University of Guelph Research Shop regarding

opportunities to increase customer accessibility to personal water use data and create associated

engagement platforms to direct customer conservation opportunities based on known customer

attributes. Based on the these discussions, a project was initiated with the University of Guelph

School of Computer Science to develop a Water Conservation Web Portal which would draw upon

personal household consumption information, following account holder approval, to form

customized customer engagement reporting and links to supporting City resources as merited by

household resource utilization and other data inputs provided by the customer. Development of this

tool is currently ongoing at this time with release tentatively scheduled for late 2015.

11. Template Assisted Crystallization Performance Study

With high levels of naturally occurring hardness in the City’s groundwater source, the use of

residential ion exchange water softener technologies is quite common amongst Guelph households,

measured to be present in approximately 77 per cent of local households as part of a 2009

residential call survey. With significant annual water use and wastewater stream salt loadings

associated with the ongoing operation of these systems, Guelph Water Services in partnership with

the Region of Waterloo continue to research ion exchange technology improvements and non-ion

http://www.guelph.ca/rainwater


Page 73 of 77

exchange technology alternatives in support regional Source Water Protection commitments and

respective local water demand reduction targets.

A recent study commissioned by the US WaterReuse Research Foundation (WRRF) evaluating

alternatives to domestic ion-exchange water softeners identified viable potential in the template

assisted crystallization or TAC as an alternative to ion exchange water softening. This relatively

new technology converts calcium and magnesium (hardness) into microscopic crystals that will stay

suspended in water without forming scale on pipes and appliances. The TAC unit, certified by The

German Technical Association for Gas and Water (DVGW), reduced scale by over 90 per cent

during the WRRF study, which is comparable to ion exchange water softening. Unlike ion exchange

softeners, the TAC units require no water for backwash, and no salt.

With limited availability and uptake within the Canadian marketplace to date, the Region and City

initiated a multi-phased study in 2014 to better understand the extent of practice, appropriateness

and limitations of TAC so to inform future community education and related programming. Study

activities in 2014 included completion of a detailed TAC market assessment, engagement of early

adopters of the TAC technology and development of a performance testing protocol in consultation

with industry experts and stakeholders. As part of the next phase of the project it is planned that

field testing of a number of TAC technologies will be performed in a controlled environment to

assess performance of these technologies versus the severe hard water sources seen locally.

Following completion of the testing and analysis of results attained, it is planned that a final report

for the study will be released in late 2015/early 2016 for public reference.

Water Reduction Target Progress

In 2006 City Council endorsed the Water Supply Master Plan (WSMP). This detailed Master Plan evaluated

the water demand associated with projected growth over a 50 year planning horizon, as well as alternative

sources of new water supply. Water conservation was identified as the most cost-effective and

immediately available source of new water supply and was ranked as the number one priority. The WSMP

included three reduction targets based on 2006 daily water production volumes:

Reduction of 10 per cent (5,300 m3/day) in average day water use by 2010;

Reduction of 15 per cent (7,950 m3/day) in average day water use by 2017; and

Reduction of 20 per cent (10,600 m3/day) in average day water use by 2025

As of December 31, 2013, annual average day water production has decreased by 5,923 m3/day (14 per

cent) since 2006, with an estimated direct savings of 7,116 m3/day attributed to community participation

in the City’s Water Conservation Programs. This observed reduction to date places the City in a

competitive position to reach its 2017 water reduction target. Further to the information above, Figure 7

below shares estimated water savings to date versus the annual conservation program reduction targets

of the City’s 2009 Water Conservation Strategy:

Figure 7: Water Conservation and Efficiency Strategy Update:

Estimated Annual Savings vs. Program Reduction Targets

In July of 2014 Guelph City Council endorsed the Water Supply Master Plan Update. Through update of

this Master Plan, water capacity reclaimed through Water Conservation and Efficiency continued to be a

top priority in achieving a sustainable and cost effective community water supply. Through the evaluation

of the feasibility and value of multiple Water Conservation Program Scenarios the final Master Plan

recommended the City’s demand reduction target be revised to achieve an addition 9,150m3 per average

day of supply capacity by 2038, the planning period of the City’s Official Plan. With reference to this new

time based goal guiding the City’s Water Efficiency Program, it is now necessary that Guelph Water

Services revise its 2009 Water Conservation and Efficiency Strategy to identify preferred program

resources for the next planning period of 2016 to 2020. Update of this strategy will initiate in January of

2015 with further information on this strategy and opportunities for public involvement to be made

available at www.guelph.ca/ourstoconserve.
