1 Introduction

Saint Mary is a parish located in the northeast section of Jamaica. With a population of

121,353, it is one of Jamaica's smallest parishes, located in the county of Middlesex. Its

chief town and capital is Port Maria, located on the coast.

St. Mary is located at latitude 18°09'N, longitude 77°03'W. It is bordered by Portland in the east, St. Ann in the west, and parts of St. Catherine and St. Andrew in the south.

The parish covers an area of 610 km², making it Jamaica's fifth smallest parish. The terrain is mountainous, rising up to almost 4000 feet at the highest point, but there are no distinctive mountain ranges. The climate is varied, like most parishes on the island. The eastern section of the parish has shale rock and an intricate surface draining pattern, while the western section is limestone with predominantly underground rivers.

There are three main rivers in Saint Mary, the Rio Nuevo, Wag Water River and White River.

National Water Commission (NWC) produces some 180 million gallons (0.82 million cubic

metres (MCM)) of water per month in St. Mary (included is the import from St Ann Bogue

of 41 million gallons (0.19 M C M)) from eighteen (18) surface sources. The average billed

consumption by volume is approximately 55 million gallons per month which translates to

an average non-revenue water (NRW) of 125 million gallons per month i.e. 65% of

production. This unacceptable high level of NRW has had a negative impact on the level of

service provided to our valued customers of the parish and on its financial performance of

NWC.

NWC now provides water to some 81.6% of the population in St. Mary, which is an

improvement over that in 2001 when the level of coverage was 60%. The reliability of

service to those who are served by NWC is estimated to average 18.4 hours per day.

A Water Supply Parish Plan (WSPP) has been prepared for the parish and is presented in

this document. The WSPP for the parish will involve an expenditure of $10,119.07 Bn over

the next twenty years in carrying out a number of water supply rehabilitation and upgrading

works. A substantial portion of the proposed works is aimed at addressing the unacceptable

high level of NRW through mains replacement in our distribution systems of aged,

encrusted and undersized water supply infrastructure and improvement in water supply

pressure & flow management. The plan is to increase water supply coverage for the parish to

86% of the parish population by end 2030 and service reliability to 22.5 hours per day

during the corresponding period.

2 Existing Water Supply System

2.1 Water Resource

Surface Water

100% of the water abstracted in the parish is obtained from surface sources. The following

are the main surface sources in the parish:

Iterboreale Spring

Pottinger Spring

Sand Hill Spring

White River

2.2 Water Supply Systems

The combined reliable yield from these surface sources are 6 mgd. The output from these

sources range from 5 mgd during the dry period and increases to 6.5 mgd during the wet

period.

The water supply network throughout the parish dates back to the 1950’s. These aged

infrastructure are now undersized due to the expansions of developments within the parish,

these challenges have contributed to unacceptable level of service there. Information on the

water supply network is summarized in table 2.1 below.

3 NON-REVENUE WATER LEVELS

Set out in figure 3.1 is the annual water balance for St. Mary. This was derived from the

water balance which was prepared for each of the water supply systems in the parish. The

water balances are based on flow measurements that were conducted at sections of the water

supply network and examinations of customer and records.

NWC water production facilities provide approximately 10.15 M cubic meters of water per

year to the water supply network in St. Mary i.e. 2,232 M gallons per year. Physical losses

amount to 6.4 M cubic meters (1,407 M gallons) per year. This represents 63.05% of the

amount produced.

Revenue water in the parish is only 3.43 M cubic meters which is only 33.8% of the water

produced.

It would be noted that 8,760 M cubic meters of water is attributed to unauthorized

consumption (i.e. 0.000863% of production). This is largely due to illegal connections to

some of the cross country transmission pipelines to obtain water for informal settlements (eg

Annotto Bay).

4.1 Parish Population

General

In 2001 the population in St. Mary was 120,389, which was a 0.05% increase over the 119,790 in

1991. Based on an annual population growth rate of 0.025%, it is estimated that the population

in the parish in 2010 is 121,353 persons.

There were 24077 households in 2001 of which 14,446 had piped water (61%). There are now

19,800 customer accounts of which some 17622 are domestic accounts. Based on this

information, it is estimated there was a 20% increase in the number of dwellings with piped

since 2001, an average annual increase of 2%. It is estimated that 81.6% of the population of the

parish now has piped water population data for systems.

Demand Centres

The enumeration districts (EDs) that were used in the 2001 population census was used to

establish priority areas that will be targeted to be provided with water supply. EDs with

7


population densities in excess of 150 persons per square kilometres were grouped to form these

demand centres.

TYPES OF DATA

As far as possible, each demand centre (DC) is linked to a water supply system. It is related to a

water distribution system that now serves it or has the potential to serve by it.

Set out in table 4.1 is information showing the population in each DC, indicating estimates for

2010, 2015, 2030.

The current water supply situation in St .Mary is that, overall, there is deficit of water in the

parish to meet the water requirement, even with the existing technical losses (leaks, tank

overflows, etc). The average daily water production in the parish is 6.8 million gallons; the

average day water consumption (domestic, commercial, institutional, etc), which is based

on 82% supply coverage, is estimated to be 1.9 million gallons and the technical water

losses is estimated to be 1.85 million gallons per day. Based on average water

consumption, there is an estimated deficit of some 0.4 million gallons per day.

Water Supply Improvement Plans

4.1 Set Up and Detailed Audit of the St. Mary Water Supply System

The level of NRW in the parish is unacceptably high. As shown in the sections above, the

overall NRW.

In order to proceed with the audit of the network and to obtain reliable and accurate

information on users and consumption, the following activities is required to be implemented

within the Parish during the Audit Phase:

Technical Area:

• Network survey to define and locate pipes (material and size) & fittings (valves, PRV, fire hydrants) to draw up the network inventory. Then all the information gathered on

11


site will be transferred in Geographic Information System (GIS) following the NWC specifications.

• Investigation of all the NWC facilities (production facilities, reservoirs and pumping stations). All defects and anomalies detected and remedial works for repairs and/or upgrading have must be clearly stated for every facility.

• Flow & pressure measurements as well as level measurement of reservoirs at production facilities, on the trunk mains and various off-takes.

• Leak detection campaign on the entire network and mapping of leaks detected to further decide for pipe section replacement.

• Establishment and set-up of network models complying with the network operation and measurements carried out.

• Network partition into District Metering Area (DMA) to monitor flows and NRW control with definition of equipment (valves and bulk meters) to be installed.

• Setting-up of pressure management program including evaluation of existing pressure zones and Pressure Reducing Valves (PRV) and definition new pressure areas with location for new equipment.

Commercial Area:

• “Door to Door” Consumer survey audits to ascertain specific elements of the water supply among the residential & commercial users: to locate the NWC users (mapping under GIS), to check the status and condition of water meters installed on site, to gather other relevant information regarding the supply and to find out illegal connections.

• CS analysis to check the reliability and accuracy of the NWC database, to analyze trends of consumption and users and to establish the initial billable consumption.

• Consumption profiles measuring campaign to analyze the apparent losses engendered by the customer metering policies and thereof to optimize the invoicing /revenues of NWC by defining new metering policies for domestic and commercial users.

• Specific investigation on site to check the discrepancies between the CS database and the field, mainly for the temporary and permanent disconnected accounts as well as for the accounts with zero/low consumption.

4.2 Cost of Audit

The total cost to undertake the proposed set up and audit of the St. Elizabeth water supply

system is $92M. A breakdown is provided in the table below.

4.3 Expected Benefits

The detailed audit of the St. Mary Water Supply system will provide information that will

be used to help in defining detailed NRW reduction intervention activities. The results of

the audit will be used to target the most critical sections of the parish water supply system

that require attention and assist in scheduling of the required works.

The information will be used to populate the asset database for the parish which will form

a critical part of the asset management system (AMS) that will be established for St.

Elizabeth. A fully functional AMS will be a valuable operational tool that can be used to

sustain the benefits that will be derived from the various projects and activities that are set

out in this document.

5.0 Water Supply Improvement Plans

Introduction

It is planned to undertake a number of water supply improvement works in St. Mary to address

supply deficiencies and to improve overall operational efficiencies. The planned works will

focus on reducing the high level of technical losses (estimated to be in excess of 65% of

production), largely due to the aged water supply infrastructure; strengthening the transfer

capacities of critical water transmission mains, to enable transfer of water within and between

water supply systems and facilitating supply flexibility between water supply systems; and

water supply extensions to areas that are not now been served.

A comprehensive audit of the water supply systems in parish will be undertaken early stages

in order to identify optimal steps that should be taken to deliver early gains in the reduction of

13


NRW. This will include establishing district metered areas (DMAs) and setting up monitoring

systems.
