Sanitary Sewer Overflow Response Planning

II-1 City of Sausalito


SECTION II -- INTRODUCTION

This section addresses Sanitary Sewer Overflow Response Planning (Section II of the Order) for the City of

Sausalito.

REQUIREMENTS OF THE EPA AMENDED ORDER FOR COMPLIANCE

In compliance with the EPA Order, Section II, the City submitted a Sanitary Sewer Overflow Response

Plan (“SSORP), including Record Keeping, Public Notification, and Regulatory Agency Notification and

Reporting (the “Plan”), to the EPA on October 15, 2008 and immediately commenced and has continued

implementation of the Plan. In January 2014, the City updated its Sewer System Management Plan and

Overflow Emergency Response Plan (“OERP”) and integrated the SSORP into the OERP.

In May 2013, the City developed a Sanitary Sewer Overflow and Backup Response Plan (also known as

Emergency Response Plan or ERP) that discusses the City’s guidelines in responding to, relieving, cleaning

and decontaminating sanitary sewer overflows and backups that occur as a result of lift station

malfunctions within the City’s service area.

In 2016, the City completed a biennial SSMP Audit, and in 2018 the City is completing a comprehensive

update to the SSMP document.

In conjunction with SSO Response Planning, during the period from October 1, 2016 through September

30, 2018, the City completed the following training:

knowledge and expertise through the implementation of the California Water Environment Association

(“CWEA”) certification program. All sewer system maintenance employees must apply for and pass the

CWEA Collection System Maintenance Grade I Certification within one year of being employed with the

City of Sausalito and maintain that certification as a minimum condition of continued employment.

As of September 30, 2018, two of the three City of Sausalito sewer system maintenance employees hold

CWEA Collection System Maintenance Grade I Certifications. The Sewer System Coordinator holds a

CWEA Collection System Maintenance Grade IV Certification.

Information about SSOs that occurred during the Reporting Period is presented in Section III.

SECTION III

Collection System Maintenance and Management

III-1 City of Sausalito


SECTION III -- INTRODUCTION

This section addresses Collection System Maintenance and Management activities conducted by the City

of Sausalito, including the following sub-sections:

Sewer System Cleaning and Root Control Program

Maintenance Management System

Pump Station Reliability Certification

III.A. SEWER SYSTEM CLEANING AND ROOT CONTROL PROGRAM

The EPA Order, Section III.A.2 includes the following requirements:

III. COLLECTION SYSTEM MAINTENANCE AND MANAGEMENT

A. Sewer System Cleaning and Root Control Program:

2. By October 15 of each year, (SMCSD, TCSD, and) the City of Sausalito shall each

submit annual reports to EPA documenting the activities of each agency’s sewer cleaning

and root control program during the previous annual cycle. The annual reports shall

include the number of miles of pipe cleaned as part of the routine and “hot spot” cleaning

programs and miles of pipe treated by each method used for controlling roots. (SMCSD,

TCSD, and) the City of Sausalito shall include a description of the success of the sewer

cleaning and root control program at preventing blockages and sewage overflows as well

as any changes to be made to the program to further reduce spills.

ROUTINE SEWER SYSTEM CLEANING

During the Reporting Period, the City has maintained a routine cleaning program, exceeding the

guidelines set forth by the Order. Sewer cleaning is performed using the City’s mobile combination sewer

cleaning vehicle (hydroflushing with vacuum) and by machine rodding. The City’s Sewer Spill Reduction

Action Plan (SSRAP, October 2008) presented the City’s cleaning program at the time, which followed a 3-

year cleaning cycle. Since this time, the City has moved to a 12-month cleaning program, which is shown

in Figure 3-1.

Table 3-1 on the following page shows cleaning that was completed during the Reporting Period, as

reported in the City’s Quarterly EPA Reports. This table lists a total of 58.6 miles of pipe cleaned, which

accounts for multiple cleanings for the pipes that are on the City’s hot spot list.

The City does not use chemical root control methods. Therefore, all root control was addressed through

the physical root removal processes conducted during the cleaning program. The number of miles of

pipes involving root control is included in the 58.6 miles of system pipelines cleaned during the Reporting

Period.

(234% of system pipe length)

Three SSOs from the City system occurred during the two-year Reporting Period. One 650-gallon SSO

occurred in 2016-2017 and two SSOs with a combined volume of 770 gallons occurred in 2017-2018. All

but 20 gallons of flow reached surface waters.

Table 3-2 summarizes the SSOs from the public, City-maintained wastewater collection system during the

Reporting Period, as well as those from prior reporting periods beginning with the period from October

1, 2013 through September 30, 2014.

Figure 3-2 illustrates the location and cause of SSOs during this Reporting Period. The SSO from 2016-

2017 was caused by a mudslide that occurred during a wet weather event. The first of the two SSOs in

2017-2018 was caused by structural failure, and the second SSO was caused by roots from a lateral wye

connection.

“HOT SPOT” SEWER CLEANING

The length of hot spots that were cleaned by the City is included in the 58.6 miles of pipe that were

cleaned during the 2-year Reporting Period. Hot spots are assigned in locations where pipe blockages and

SSOs have occurred due to root intrusion, grease build-up, or debris. Once identified, these locations are

placed on an accelerated cleaning schedule in order to prevent future SSO events. A number of critical

pipelines on the City’s hot spot list were cleaned on a 1-week, 3-month, or 6-month cycle. The remaining

hot spot pipelines are designated as requiring cleaning on a 12-month cycle.

Tables 3-3 and 3-4 summarize pipe cleaned on a hot spot schedule during the Reporting Period. Of the

system’s 632 pipes, the CMMS reports that 596 pipes were cleaned from October 1, 2016 through

September 30, 2017, and 589 pipes were cleaned from October 1, 2017 through September 30, 2018. Of

these assets, the CMMS reports that in 2016-2017, 464 pipes or 13.9 miles were cleaned at least two

times during the year. In 2017-2018, 504 pipes or 15.3 miles were cleaned at least two times. Figures 3-3

and 3-4 show the City’s maintenance hot spots for each reporting year.

III.B. MAINTENANCE MANAGEMENT SYSTEM

The City uses Nexgen software as its CMMS. The NexGen software stores asset data, cleaning schedules,

and maintenance results, and automates work order generation for routine maintenance. Asset

information and maintenance records are available in tabular and GIS map formats. Data can be

exported as a pdf or into an excel spreadsheet.

III.C. PUMP STATION RELIABILITY CERTIFICATION

The EPA Order, Section III.C.4 includes the following requirements:

III. COLLECTION SYSTEM MAINTENANCE AND MANAGEMENT

C. Pump Station Reliability Certification:

4. By October 15 of each year, (SMCSD, TCSD, and) the City of Sausalito each shall

submit an annual report to EPA documenting pump station and force main renovations,

and upgrades during the previous year and describing projects to be completed in the

coming annual cycle.

PUMP STATION AND FORCE MAIN RENOVATIONS AND UPGRADES

The City owns three pump stations within its service area; all pump stations are operated by SMCSD.

Pump stations were inspected, and their condition and recommended improvements summarized in the

SSRAP – Volume II that was submitted to the EPA as required by the Order.

The Anchor Street Pump Station is a submersible wet well station constructed in approximately 1953,

and upgraded in 1984. This pump station was identified as one of the City’s Priority 1 Sewer Replacement

projects. The station has two pumps that alternate as lead/lag, with one duty pump and one redundant

pump. The SSRAP – Volume II confirmed that the station has adequate capacity to pump peak dry

weather flow. Based on the capacity assurance studies discussed in Section V of this Annual Report, the

station also has adequate capacity to pump peak wet weather flow from the design flow event.

This Anchor Street Pump Station Reconstruction Project was completed during the 2013-14 Reporting

Period. This Project included construction of a wye and quick-connect to allow connection of a portable

pump as well as a plug-in for generator operations for added reliability. In conjunction with the project, a

new grease interceptor, packaged lift station, and approximately 900 lf forcemain were installed at the

Spinnaker restaurant, which is located upstream of the Anchor Street pump station.

Section III




The Gate 5 Pump Station is a submersible wet well station constructed in 1953 and completely

renovated in 2002. The Pump Station Reliability Certificate submitted by the City in April 2002 reports

that the station does not have sufficient firm capacity to convey peak dry weather flows, due to excessive

infiltration and inflow (I&I). The capacity assurance studies that are discussed further in Section V of this

Annual Report identified tidal flows as the primary source of inflow and infiltration (I&I) to this pump

station. These studies confirmed results from conductivity testing completed by the City in 2009 for the

Gate 5 area and summarized in the SSRAP - Volume II. The capacity assurance studies show that after

tidal infiltration is removed, the station should have sufficient capacity to pump peak dry weather flows

and peak wet weather flows from the design storm event.

In lieu of increasing the capacity of the Gate 5 pump station, the City initiated a project to reduce I&I in

subcatchment that is tributary to the station. The City took several years to address Gate 5 Road I&I for

two reasons. This project was initially made a lower priority than the updated Anchor Street pump

station design owing to the potential presence of industrially-contaminated soils and groundwater at the

Gate 5 project site, and the presence of asbestos-cement pipe in a portion of the gravity sewers to be

replaced. When the design phase was re-initiated, the design concept was changed to reduce the

potential cost associated with these conditions. The original design concept converted the gravity sewer

system to either a low pressure pumped system or vacuum sewer system, also take into account

expected future subsidence in the area filled over San Francisco Bay Mud in World War II in order to

construct the Marin Ship Naval Shipyard, combined with sea level rise. A pressurized (or vacuum) system

would be more likely to provide the needed level of service on a long-term basis, given the anticipated

elevation changes.

The cost of either of these options, however, further complicated project funding when compared with

the debt service and debt coverage feasible under the City's existing sewer rate structure. As a result, the

project was revised to include a conventional pipeline rehabilitation project with a shorter design life-

cycle. The project was designed and advertised for bid, but was not constructed due to the prohibitive

cost of construction. The project was again revised to include sealing of manholes and sealing off

openings where seawater was entering the system between the existing pipe and an existing liner.

Construction of this project was completed in early 2017. Following the completion of construction, the

City has observed reduced inflows to the Gate 5 Road pump station and a statistically-significant

reduction in the magnitude of tidal influence on flows in the vicinity of the project. Two reports to

Sausalito's City Council documented the early assessment of the effectiveness of the project2 3and City

Staff continue to utilize depth-of-flow monitoring data to confirm that there are sustained benefits from

the work. A public mainline replacement project along the Coloma alignment of the City's system there

was also subsequently constructed.

As part of the Gate 5 Road Pipeline Replacement Project, the City had planned to install a quick-connect

and valve on the existing 6-inch wye cleanout located in a vault northeast of the pump station. This

quick-connect installation was completed by SMCSD in 2013 and will enable a portable pump connection

if required.

The Whiskey Springs Pump Station is a dry pit non-submersible pump station constructed in 1971. The

pump station is operated by SMCSD. This pump station is described in the SSRAP Volume II as in good

condition. In the prior reporting period, the City purchased and installed a Cummins Power Generation

System (Model C150-D6RT) with Model QSB7-G3 USEPA Tier III compliant trailerable engine at the

station.

Based on the capacity assurance studies discussed in Section V of this Annual Report, the station does

not have adequate capacity to pump peak wet weather flow from the design flow event. In order to have

sufficient firm capacity to pump peak wet weather flows, both of the existing pumps must be upsized to

465 gpm.

During wet weather events, in order to provide sufficient capacity in the conveyance system downstream

of the Whiskey Springs pump station, SMCSD must divert upstream interceptor flow using the SMCSD

Scotty’s pump station. SMCSD has completed the design for a single pump station that combines

flows from the Whiskey Springs pump station with flows from the adjacent Scotty’s pump station.

The City’s share of this project is approximately$1.5 million and its City Council has been asked at its

October 30, 2018 meeting4 to enter into an agreement with the Sausalito-Marin City Sanitary District

to provide that amount as a firm fixed price for a project that will replace the City's pump station

and the District's wet-weather pump station across Coloma with one new station. The City is also

initiating a new rate study in order to develop a rate structure that builds the reserves needed to

continue to complete needed capital improvement projects in the future.

Collection System Assessments

IV-1 City of Sausalito


SECTION IV -- INTRODUCTION

This section addresses the inspection methods and findings of the sewer pipe condition assessments

conducted during the Reporting Period and the estimated miles of sewer pipe and number of

maintenance holes planned to be inspected during the next reporting period.

IV.A. SEWER PIPE MAINTENANCE HOLE INSPECTION AND CONDITION ASSESSMENT

The EPA Order, Section IV.A.3 includes the following requirements:

IV. COLLECTION SYSTEM ASSESSMENTS

A. Sewer Pipe and Maintenance Hole Inspection and Condition Assessment:

3. Beginning October 15, 2009, (SMCSD, TCSD, and) the City of Sausalito shall each

submit an annual progress report to EPA summarizing the inspection methods and

findings of the sewer pipe condition assessments conducted during the previous year and

the estimated miles of sewer pipe and number of maintenance holes planned to be

inspected during the current year.

COLLECTION SYSTEM INSPECTION METHODS

The City has historically inspected the collection system pipelines with its own crews and equipment, and

has supplemented these inspections using closed circuit television (“CCTV”) inspection contractors. For

sewer pipelines with maintenance holes located in readily accessible locations, CCTV data is collected

with the use of fully equipped CCTV vehicles. Each vehicle carries all of the inspection, video capture, and

recording equipment needed to televise a sewer pipe. Pan and tilt cameras are used to give the

inspectors increased flexibility in identifying and assessing the main infrastructure as well as the service

lateral connections. For mains with maintenance holes that are located in remote or difficult to access

areas, inspection contractors may utilize a portable push camera, capable of viewing, recording and

identifying defects located in the pipe. Upstream and downstream manholes are inspected concurrently

with associated pipes.

CONDITION ASSESSMENTS FOR CURRENT AND FUTURE REPORTING PERIODS

During the Reporting Period, the City conducted CCTV inspection on 4,562 feet of sewer pipelines. Figure

4-1 shows the locations of the 19 pipe segments that were inspected. All of these inspections occurred

between October 1, 2016 and September 30, 2017, and were conducted to locate existing structures and

laterals, inspect prior installations, and gather system data needed to plan pipe replacements. The City

plans to inspect approximately 2 miles of pipelines during the next reporting period.

IV.B. CAPACITY ASSESSMENT

The Order, Section IV.B.2 includes the following requirement:


B. Capacity Assessment:

2. By October 15, 2009, and each year thereafter, (SMCSD, TCSD, and) the City of

Sausalito each shall submit a report to EPA providing the results of collection system flow

monitoring, including the average dry weather flow and peak wet weather flow from its

collection system.

SECTION IV




The City’s dry and wet weather flows are measured by permanent meters that are located at two of the

SMCSD wastewater pump stations (Main Street and Locust Street pump stations).

SMCSD measures total flows in the regional conveyance system at the SMCSD Marin City pump station,

and then subtracts TCSD flows as measured at the TCSD Bell Lane pump station to quantify SMCSD flows.

A small part of the SMCSD Marin City collection system drains to the unmetered Highway Booster Pump

Station, which discharges to the SMCSD interceptor.

SMCSD then collects flow data at the Locust Street and Main Street pump stations, and subtracts

calculated SMCSD flows to obtain the City’s flow quantities. For average dry and wet weather flow data

for the Reporting Period, see the SMCSD annual EPA report


B. Capacity Assessment:

a) By October 15, 2010, (SMCSD, TCSD, and) the City of Sausalito each shall

complete an assessment and submit a report to EPA on collection system flows

and hydraulic capacity.

Although there is no reporting requirement for flow measurement in the current Annual Report, the

following information is repeated from prior Annual Reports for information and reference.

AREAS OF SIGNIFICANT INFLOW AND INFILTRATION

The City completed a flow monitoring program during 2008/09 that measured dry and wet weather flows

throughout the City’s collection system service area. The collected data were analyzed to identify areas,

sources, and quantities of significant I&I. The flow monitoring program was described in the Sewer Spill

Reduction Action Plan Report on Flow Monitoring, RMC, October 2009. Figure 2-2 from the Flow

Monitoring Report defines the monitored basins and is presented as Figure 4-2 in this Annual Report. The

I&I analysis was presented in further detail in Chapter 4 of the Capacity Assessment Plan, West Yost

Associates, October 2010.

DRY WEATHER I&I

Inflow and infiltration from groundwater and tidal flows were evaluated based on flow data collected

during the dry weather period from January 12 to January 18, 2009. During this period, three of the

eleven monitored basins included flow and flow patterns that exceeded the expected flow volumes and

patterns for base wastewater flows (BWF). For two of the basins, the infiltration included groundwater

infiltration (GWI) that included a tidal component. Tidal flows were derived by quantifying GWI with flow

patterns that followed tidal patterns for the San Francisco Bay.

Flows from Basin 1-E, monitored by Meter S-2, included groundwater and tidal components. The tidal

influence appeared only during periods of very high tide. Therefore, a lower tide period of January 26 to

30, 2009 was used to assess the BWF and GWI component, and higher dry weather flow periods used to

quantify tidal I&I.

Flows from Basin S-4B, monitored by Meter S-9, also included groundwater and tidal infiltration

components. It was difficult to identify periods of flow that were not influenced by tidal elevations.

Therefore, BWF for this basin was derived from water usage data.

SECTION IV




Flows from Basin S-1F, monitored by Meter S-3, included a minor groundwater infiltration component

and no apparent tidal component. Estimated GWI, including tidal infiltration, is summarized in Table 4-1.

WET WEATHER I&I

Wet weather I&I was evaluated based on flow data collected during two wet weather events: February

15 to 18, 2009 and February 22 to 24, 2009. During this period, all basins included varying levels of wet

weather I&I.

Peak hourly flows were compared to average dry weather flows to determine the wet weather peaking

factor for each basin. Wet weather peaking factors determined relative levels of stormwater inflow into

the basins, as shown in Table 4-2.

The high peaking factors are the result of substantial tidal infiltration into this basin and not the

result of stormwater inflow.

Total flow volumes were compared among basins using three different methods for evaluating I&I: flow

per acre; flow per inch-diameter-mile of pipe; and percent I&I. Results from all methods were compared

to determine the level of infiltration in each of the monitored basins. Infiltration analysis results for wet

weather period from February 15 to 18, 2009 are shown in Table 4-3. A similar analysis that was

completed for the following wet weather period from February 22 to 24, 2009 was presented in a prior

Annual Report.

SECTION IV




Model results, calibrated with previously collected flow monitoring information, did not match flows

within several sewer basins that were developed within the City’s service area. Basins S-2A, S-3B, S-4A,

and part of Basin S1-D flow directly to the SMCSD interceptor, and are located close to the San Francisco

Bay. The I&I analysis could not quantify extraneous flows from these basins. However, total Sausalito

flows as calculated by SMCSD for the flow monitoring period indicate that these basins received I&I. The

City plans additional flow monitoring within these and other basins to further refine information

regarding system-wide I&I. This information will also allow prioritization of sewersheds for increased

scrutiny of private infrastructure. The City Council has expressed willingness to consider adoption of

revisions to the City's sewer ordinance to grant additional authority to compel repairs to private facilities

when City standards are not complied with but the findings for a public nuisance cannot be made.

CAPACITY RESTRICTIONS

A hydraulic model was developed of the City’s main trunk sewers. The model was calibrated to dry and

wet weather flow as measured during the 2008/09 flow monitoring program. The system was then

evaluated for the ability to convey flows from the SMCSD design flow event.

The capacity analysis made several assumptions related to SMCSD. SMCSD is currently addressing

conveyance system capacity restrictions that might otherwise impact City flows. These assumptions are

discussed in the context of the capacity constraints listed below.

In order to maintain consistency with the capacity analysis conducted by SMCSD, the City’s capacity

analysis used the December 31, 2005 design flow event. SMCSD has analyzed historical flow and rainfall

events, and has determined that the storm of December 31, 2005 was an approximate 5-year frequency

event with respect to peak RDII flows in the system. Rainfall data for the event was collected at the

SMCSD Bell Lane Pump Station.

The capacity analysis identified four pipe locations and two pump stations within the City’s system that

have capacity constraints (surcharge) during the design flow event. The four pipeline locations are

described below. The two pump stations with capacity constraints are discussed in Section III.C. Pump

Station Reliability Certification.

Coloma Street pipeline between Olima Street and Bridgeway Blvd had flows that were 106 to

126 percent of full pipe capacity during the design wet weather flow event.

Nevada Street pipeline from Tomales Street to Bridgeway Boulevard had flows that were 119

to 133 percent of full pipe capacity during the design wet weather flow event.

Gate 5 Road pipeline from Coloma Way to Harbor Blvd had flows that were 124 to 129

percent of full pipe capacity during the design wet weather flow event.

Bridgeway Boulevard pipeline between Turney and Locust Street had one segment that was

107 percent of full pipe capacity during the design wet weather flow event. This pipe

segment is directly upstream of the SMCSD Locust Street pump station. During the flow

monitoring program, meters located in manholes at 210300 (Meter S-4) and 220101 (Meter

S-5) surcharged, in a flow event that was less than the design wet weather storm. It is

possible that capacity restrictions at the SMCSD Locust Street pump station resulted in these

surcharge locations.

The observed surcharge conditions may be related to a high level of I&I in this location that

could not be quantified based on the basin-wide flow monitoring program conducted in

2008/2009. A focused flow monitoring program will better define contributions from I&I to

localized flows upstream of the Locust Street pump station. In addition, the SMCSD has

completed improvements to the Locust Street pump station since the basin-wide flow

monitoring program conducted in 2008/2009.

IMPACTS OF THE CITY’S FLOWS ON THE SMCSD SYSTEM

The City’s capacity analysis identified surcharging but no overflows during the design wet weather flow

event, with the exception of flows in the Gate 5 Road area. The capacity analysis identified significant

inflow in the Gate 5 Road area, where, as a result of high, fluctuating groundwater, the pipes receive high

levels of tidal infiltration. In the past, this issue was partially addressed through pipe lining. However,

after lining, infiltration continued to enter through leaking manholes and through the annular space

between the pipe and liner. In 2017, the City completed construction of a project that sealed manholes

and sealed the annular space between host pipe and pipe liner. As a result, I&I is measurably lower

within the basin, and the City estimates that pumped flows from the Gate 5 Road pump station have

decreased during peak flow events (generally during high tides) significantly. The City and the Sausalito-

Marin City Sanitary District continue to accumulate and analyze both pump station run time and depth of

flow in collection system data to confirm that a sustained reduction in I&I has occurred. An analysis after

SECTION IV




approximately one year5 indicated a reduction in peak dry weather, high-tide flows to the pump station

of 40%.

Capacity Assurance

V-1 City of Sausalito


SECTION V -- INTRODUCTION

This section describes the improvements that were identified in the condition and capacity assessments

completed in Section IV. The section describes the effects, if any, that existing capacity limitations and

future upgrades may have on the SMCSD conveyance and treatment systems. The plan is designed to

simulate spills from the collection system during design wet weather flows.

REQUIREMENTS FOR THE EPA AMENDED ORDER FOR COMPLIANCE

V.B. CAPACITY ASSURANCE PLAN

The EPA Order, Section V.B includes the following requirements.

V. CAPACITY ASSURANCE

B. Capacity Assurance Plan:

1. By October 15, 2010, (SMCSD, TCSD, and) the City of Sausalito shall propose and

schedule improvements identified in the condition and capacity assessments completed in

Paragraph IV. The plan(s) shall consider the effects that existing capacity limitations and

future upgrades may have on the SMCSD WWTP and its other contributing collection

systems. The plan(s) should be sufficient to eliminate spills from the collection systems

and wastewater treatment plant during peak wet weather.

2. By October 15, 2013, (SMCSD, TCSD,) and the City of Sausalito shall complete the short-

term improvements identified pursuant to Paragraph V.A. The improvements shall

address preliminary I&I control, conveyance of peak flows, storage of peak flows, and

improvements to treatment plant capacity.

Four pipeline replacement projects and one pump station improvement project are proposed to provide

the system with sufficient capacity to convey peak flows from the design wet weather flow event. Project

descriptions are included below. More detailed project information and costs are presented in the City’s

Pipeline Rehabilitation and 10-Year Capital Improvement Plan, West Yost Associates, October 2010, (10-

Year CIP), which was included in Appendix E to the 2010 Annual Report. The City had originally planned

to obtain CWSRF funding for these projects, and to complete the projects within a five-year period.

However, the process to secure CWSRF funding for a single project (not on this list) took approximately 4

years. This funding schedule was not sufficient to allow the City to complete these projects as planned.

The City issued wastewater bonds in late 2014 and was able to realize a total of more than $6 million in

funds for capital improvements. On that basis, the City has completed one project, and plans to complete

the remaining capacity-related projects within three years assuming that capital resources are available.

Project 1 --Nevada Street Pipeline Replacement project. This 6-inch diameter pipeline is planned

to be removed and replaced between Tomales Street and Bridgeway Boulevard (Manhole Nos.

370400 to 370100). In order to convey design wet weather flows, the pipe segments require

upsizing by one pipe diameter. A smaller project, to eliminate eucalyptus root intrusion into a

short segment of public sewer main with a history of SSOs, was prioritized to occur before this

planned pipeline improvement.

Project 2 -- Coloma Street Pipeline Replacement project. This pipeline is currently 6-inches in

diameter near Olima Street, transitioning to 8-inches in diameter near Bridgeway. In order to

SECTION V

Capacity Assurance



convey design wet weather flows, the pipe segments require upsizing by one pipe diameter. The

project area also includes the Whiskey Springs Pump Station Capacity Improvement project,

which provides firm capacity to convey wet weather flows from the design flow event. Upgrade

of the Whiskey Springs pump station is included in the SMCSD Scotty’s Pump Station project,

which has reached approximately 65% completion in the design phase.

Project 3 -- Caledonia at Turney Street Pipeline Replacement project. This 12-inch diameter

pipeline will be removed and replaced between Turney and Locust Streets. (Manhole Nos.

210200 to 210001). This pipeline is currently 12-inches in diameter. In order to convey design

wet weather flows, the pipe segments require upsizing by one pipe diameter.

Gate 5 Road Pipeline Replacement project. Replacement of this 6-inch diameter pipeline from

Coloma Way to Harbor Blvd (Manhole Nos. 430107 to 430104), and on parts of Harbor Blvd, was

designed and bid. One bid was received that was significantly higher than the Engineer’s

estimate for the project. The project was amended to address the most critical sources of I&I by

relining manholes and sealing the annular space between existing carrier pipe and liner.

Construction of the amended project was completed in 2017.

Figure 5-1, modified from that originally submitted with the 2010 annual report, displays the locations of

these projects.

SECTION VI -- INTRODUCTION

This section documents sewer repair, rehabilitation and replacement activities completed during the

previous year and describes projects to be completed in the coming reporting period (Section VI.B of the

Order).

REQUIREMENTS FOR THE EPA AMENDED ORDER FOR COMPLIANCE

VI.A. SEWER REPAIR, REHABILITATION AND REPLACEMENT

The EPA Order, Section VI.A. includes the following requirements.

VI. INFRASTRUCTURAL RENEWAL

A. Sewer Repair, Rehabilitation, and Replacement:

By October 15, 2010, (SMCSD, TCSD, and) the City of Sausalito shall each submit a plan to

EPA for both short-term (repairs of acute defects to occur within one year of inspection

and assessment completed) and long-term repair, rehabilitation and replacement of

sewer pipes. The plan shall include a schedule and financial plan. The plan shall be

sufficient to: 1) ensure timely repair of sewer pipes in imminent danger of failure or

blockage; 2) ensure the long range sustainable rehabilitation or replacement of obsolete

assets; 3) improve system performance and reduce spills caused by pipe defects and

blockages from roots and debris; and 4) control inflow and infiltration as needed

pursuant to the Capacity Assurance Plan in Paragraph V.B. The plan shall include:

1. The length of pipe repaired, rehabilitated, or replaced during the last 20 years;

2. An estimate of the miles of sewer pipe to undergo emergency repair or

replacement each year;

3. An estimate of the miles of sewer pipe to be rehabilitated or replaced over the

next 10 years and identification of the pipe reaches to be rehabilitated or

replaced in the next 5 years;

4. A 10-year financial plan for short-term and long-term repair, rehabilitation, and

replacement of sewer pipes; and

5. A plan to address private lateral repair, rehabilitation replacement as needed

pursuant to the Capacity Assurance Plan in Paragraph V.B.

In 2009, the City established a 5-year CIP, and in 2010, completed a 10-year CIP to prioritize and schedule

future pipeline replacements. The CIP was reviewed in 2014 as part of the City’s Sewer Rate Study.

The projects that were identified in 2010 as being needed to address capacity constraints and other

critical rehabilitation needs are summarized in Table 6-1. Seven of the eleven proposed priority

improvements have been completed, are in construction, or are in the design phase.

In addition to these planned capital improvements, the City continues implementation of its lateral

replacement program, and also plans to replace lower laterals in conjunction with mainline pipeline

replacements.

VI.B. ANNUAL REPORT

The EPA Order, Section VI.B includes the following requirements.

VI. INFRASTRUCTURAL RENEWAL

B. Annual Report:

By October 15 of each year, (SMCSD, TCSD, and) the City of Sausalito shall each submit an

annual report to EPA documenting sewer repair, rehabilitation or replacement activities

completed in the previous year; describing projects to be completed in the coming annual

cycle; and providing an updated 10-year Capital Improvement Plan (CIP).

Sausalito is in various stages of implementation for many of the projects listed in Table 6-1. These

descriptions use the naming convention that was utilized in the 2009 CIP:

Priority 1a – Gate 5 Road Pipeline Replacement Project. This project was designed as a

conventional pipeline removal and replacement project with the intent of reducing tidal I&I.

The project was designed and advertised for bid. One bid was received that was significantly

higher than the engineer’s estimate, and significantly higher in terms of unit cost per foot of

pipe installed to be considered reasonable. Therefore, the project was revised to address the

most significant sources of I&I through manhole repairs and also sealing the annular space

between carrier pipe and impervious pipe liner. Construction was completed in 2017.

Performance monitoring continues to confirm whether sufficient I&I was removed to relieve

capacity needs at the Gate 5 Road pump station. Initial results are a 40% reduction in dry

weather peak (tidally-influenced) pump run times at Gate 5 Road pump station.

Priority 1b – Spinnaker Grease Interceptor, Pipeline, and Anchor Pump Station Rehabilitation

project. This project has been successfully completed.

Priority 1c – Prospect Avenue Sewer Replacement was intended to correct known pipeline

defects that contribute to I&I. The project was originally determined to be a priority for the

City because it would dovetail with a stairway replacement project that was grant funded.

The funding for the stairway project was cancelled, and the Prospect Avenue pipeline was

repaired through localized point repairs in lieu of replacement.

Priority 2b– Beach Main (including Valley to Main Pipeline Replacement) – Rehabilitation

Project. This project addresses pipelines that are partially or fully submerged in the San

Francisco Bay, and present a reliability concern to the City and the SMCSD. Preliminary

design and environmental planning were initiated in 2009. Significant permitting and project

implementation challenges have become apparent during this effort, delaying final design

and construction. The City is integrating this and several other longer-term projects into its

Sea Level Rise Vulnerability planning efforts. The funding available from the City’s sewer

ratepayers is inadequate to address all of the infrastructure needs in the area of this project.

Priority 3b – Woodward to Toyon Avenue Sewer Replacement was successfully completed

during a prior reporting period.

Whiskey Springs improvements have been combined with the Scotty’s pump station project

that is in process by SMCSD. The project design has been completed. The City’s portion of

remaining estimated design and construction costs is $1.5 million and the SMCSD has agreed

to lead that project through delivery for that firm, fixed price.

Sanitary Sewer Point Repairs. A total of 763 feet of sewers and 6,755 feet of private laterals

were replaced by the City; 121 laterals were installed by private contractors and inspected by

the City; 41 manholes were partially rehabilitated; 6 rodding or lamphole frames and lid were

replaced in kind or, in some cases, with a manhole; 1 grease interceptor was installed

privately and inspected by the City; and 4 sewer ejector pumps were maintained or replaced

privately and inspected by the City.

10-YEAR CAPITAL IMPROVEMENT PLAN

The City’s most recent 10-year Capital Improvement Plan is included as an attachment to the City’s Sewer

Rate Study that was completed in 2014. The study identified, and the City issued wastewater bonds for

over $5 million in improvements. The 10-year plan prioritizes needed improvements and distributes their

implementation to support continued planned expenditures of approximately $1,060,000 annually.

Annual Progress Reports

X-1 City of Sausalito


SECTION X -- INTRODUCTION

There are no reporting requirements for the current period for Sections VII and VIII of the Order. Also,

the Quarterly Report required by Section IX of the Order was submitted by the City separately. Section X

of this submittal includes the City’s updated wastewater collection system annual budget for the current

year as well as the cost of compliance with the Order (Section X of the Order).

REQUIREMENTS OF THE EPA AMENDED ORDER FOR COMPLIANCE

The EPA Order, Section X includes the following requirements:

X. ANNUAL PROGRESS REPORTS

…The annual progress reports shall also contain an updated wastewater collection

system annual budget for the current year and the cost of compliance with this Order.

The adopted capital and operating budget for the City's wastewater enterprise is presented in Appendix

A. The Fiscal Year 18-19 capital and operating budgets for the City’s Sewer Enterprise are $2.8 million

and $2.72 million in expenditures, respectively. These budgets includes funds required to fulfill the City’s

collection system operations and maintenance needs, including the requirements of the Order as well as

planned capital projects debt service. As of the date of this report, $1.5 million in bond funding remains

needs for capital expenditures as they arise. The full version of the current budget, as well as access to

prior year’s budgets, the City’s Fiscal Transparency Tool and other financial information is available on

The City, working with SMCSD and TCSD, continues to identify, evaluate, and implement necessary

improvements to facilities, operations, and maintenance of the wastewater collection system. The City

approved a new rate structure in July 2014, following a California Proposition 218 process, and

established updated rates in July 2015, in order to fund necessary capital and maintenance improvement

programs. The City is initiating a new rate study in 2018, to confirm and update the wastewater rate

structure.
