The Regional program is forecasted to complete six months after the approved completion date and the Local program is forecasted to complete thirty months after the approved completion date.

Program Key Updates:

The key updates for the Regional Water Enterprise Capital Improvement Program include:

 The Sunol Valley Water Treatment Plant - Ozone project received 3 construction bids with the lowest bid approximately 28% ($51M) over the engineer's estimate. A bid evaluation and review of recent water and wastewater projects in California was performed to better understand factors that may have contributed to the high bids. From the evaluation, the project team concluded that the increased cost over the engineer's estimate has been experienced on other similar recent projects in California. Thi s is likely due to at least the following three factors: (1) There is a small pool of qualified contractors that have the capacity to perform a project of this size, complexity, and duration. (2) On-going uncertainty in materials and equipment pricing and availability has resulted in increased pricing to cover perceived risk. (3) Complex retrofit projects on critical facilities that must remain operational are inherently risky to Contractors. After review, it was decided to recommend that the Commission approve award of the contract to the lowest bidder.

WECIP Quarterly Report Q3-FY2023-2024 (01/01/24 – 03/31/24)  The HTWTP Filter Underdrain Replacement construction was completed, and the filters were returned to Operations. During testing and commissioning, it was discovered that backwashing of the filter media was not efficient due to poor air distribution in the air scour piping. Orifice plates were installed in the air scour piping, but backwashing is still inefficient. The contractor is continuing to investigate solutions to improve backwashing efficiency.  For the Regional Groundwater Treatment Improv ement project, two firms submitted proposals in response to the Request for Proposals (RFP) to procure a consultant to assist with project planning and long-term implementation strategy for regional groundwater treatment. The project team is reviewing the proposals for minimum qualifications, assembling an independent panel to score the proposals, preparing scoring criteria, and preparing oral interview questions.

The proposals will be scored, and oral interviews held next quarter.  For the Sunol Valley Chloramination Facility project, the commission awarded the construction contract during the February 13th commission meeting.
 For the Crystal Springs Pipeline No. 2 Reach 5 Lining Replacement project, the 65% design is in progress. After additional consideration and further evaluation of the construction schedule, the valves to be used for safe pipeline entry will be purchased through this project's construction contract. Potholing work to confirm the pipeline alignment and utilities began this quarter. Outreach to property owners and local jurisdictions impacted by the project as well as CEQA review all continued.
 The Corrosion Control Phase 2 has 11 sites, which are currently in construction. Corrosion Control Phase 3 has 19 sites and is currently in planning phase.  The San Antonio Pump Station MCC Upgrades project notice to proceed is anticipated to be issued to the Contractor, in Mid-April.
 For the Turner Dam and Reservoir Improvements project, the project team completed the final draft Condition and Needs Assessment Report, and will finalize the report in the next quarter.  For Pilarcitos Dam Improvements project, the project team continued the development of the conceptual engineering report for two alternatives, which include the permanent reservoir restriction (Alternative 5) and full dam replacement (Alternative 1).  For San Andreas Dam Facility Improvements project, the project team completed Overall Dam Embankment Stability Report, and started the preparation of Alternative Analysis Report (AAR).
 For Merced Manor Reservoir Facilities project, the team is currently updating the engineering work plan and associated planning phase schedule and will be beginning the Alternatives Analysis Report in May 2024.
 For the Southern Skyline Blvd Ridge Trail Extension project, the construction contract notice- to-proceed (NTP) was issued on January 8, 2024. The contractor started construction on the trail alignment south of Route 92.
 For the SA-1 Service Road/Ingoing Road project, the construction notice-to-proceed (NTP) letter with effective date of March 4, 2024 was issued to the contractor. Site preparation for field construction commenced.

1. CAPITAL IMPROVEMENT PROGRAM DESCRIPTION
The San Francisco Public Utilities Commission (SFPUC) Water Enterprise manages a complex water supply system stretching from the Sierra Nevada to San Francisco and featuring a series of reservoirs, tunnels, pipelines, and treatment systems. Two unique features of this system stand out: the drinking water provided is among the highest quality in the world, and water deliveries are made to most customers without the use of power, by gravity flow, while generating power at the same time.

The SFPUC is the third largest municipal utility in California, serving 2.7 million residential, commercial, and industrial customers in the Bay Area. Approximately one-third of the delivered water goes to retail customers in San Francisco, while wholesale deliveries to 26 suburban agencies in Alameda, Santa Clara, and San Mateo counties comprise the other two-thirds.

The Regional Water System consists of water storage and treatment facilities; water transmission infrastructure; buildings and structures for fa cilities and employees; communications systems; and watersheds and Rights-of- Way (ROW) lands in San Mateo, Santa Clara, and Alameda Counties as well as western San Joaquin County. The Regional Water System also includes numerous assets in San Francisco that are operated in conjunction with the regional system. The Regional Water Enterprise Capital Improvement Program (Regional Water CIP) is part of the SFPUC’s 10-Year Capital Plan (10-Year CIP), a 10-year plan of proposed appropriations including planned projects to physically improve the assets within the Regional Water System. The 10-Year CIP is updated every two years (with minor modifications in the off years) and integrated with the SFPUC’s Financial Plan and rate- setting.

Biannual updates to the Regional Water CIP also account for post-Water System Improvement Program (post-WSIP) conditions, including deferred projects not in WSIP and new projects needed to continue meeting level of service goals and to maintain facilities in a state of good repair.

There are six (6) groupings of projects in the Regional Water Enterprise CIP. The categories are:
• Water Treatment
• Water Transmission
• Water Supply and Storage
• Watershed and Lands Management
• Communications and Monitoring
• Buildings and Grounds

Changes to the approved baseline program, including any changes to continuing projects’ scopes, schedules, and budgets, are proposed as part of the biannually updated 10- year CIP to be adopted by the SFPUC Commission and approved by San Francisco’s Mayor and Board of Supervisors. The proposed revisions to the program become the new baseline for new and continuing projects’ scopes, schedules, and budgets in the beginning of the new fiscal year following SFPUC Commission adoption.

2. CAPITAL IMPROVEMENT PROGRAM STATUS

This Quarterly Report presents the progress made on Regional Water projects between January 1, 2024 and March 31, 2024. This document serves as the third (3 rd) Quarterly Report in Fiscal Year 2023-2024 (FY24) published for the Water Enterprise Capital Improvement Program.

This quarterly report includes approved scopes, schedules, budgets for the Regional Water Enterprise CIP projects and the Local Water Enterprise CIP projects that were included in the Water Enterprise Capital Improvement Program according to th e 10-Year Capital Plan for FY2023-24 to FY2032-33, presented to and adopted by the Commission on February 14, 2023, under Resolution No. 23-0037.

The 10-Year Capital Plan for FY2023-24 to FY2032-33 serves as the new baseline for project scopes, schedules, and budgets starting as of the first quarter (Q1) of FY2023-24. The 2023 Approved Water Enterprise CIP is a subset of the Regional and Local Water Enterprise 10-Year CIP for FY2023-24 to FY2032-33 and includes individual projects over $5 million that were then currently active or intended to be active by July 1, 2023 at the time proposed to the Commission on February 14, 2023.

The 2023 Approved Regional Water Enterprise CIP (2023 Regional WECIP) has twenty-five (25) projects, all of which are in progress.

Figure 2.1 shows the total Current Approved Budget for the 25 Regional projects in each phase of the program as of March 31, 2024. The number of projects currently active in each phase is shown in parentheses.

7. PROJECT STATUS REPORT
10033123 - SVWTP Ozone (CUW27202)
Project Description: In
recent years, SFPUC’s Sunol Valley Water Treatment Plant (SVWTP) has experienced more frequent taste and odor (T&O) events from seasonal algal blooms than had occurred historically. This project’s objective is to install ozone treatment facilities as a long-term solution to control T&O events encountered in the raw water supply from both the San Antonio and Calaveras Reservoir sources. This project will improve the reliability to meet water quality goals especially during warm months and during Hetch Hetchy shutdowns.

Current Forecast 07/13/23 A 09/29/23 A 08/15/24 01/12/29 Progress and Status:

During the
reporting period, 3 bids were received with the
lowest bid approximately 28%, $51M, over the engineer's estimate. The project team performed a bid evaluation and concluded that the increased cost over the engineer's
estimate has been experienced on other similar recent
projects in California and is likely due to at least the following three factors: (1) There is a small pool of qualified contractors that have the capacity to perform a project of this size, complexity, and duration. (2) On-going uncertainty in
materials and equipment pricing and availability has resulted in increased pricing to cover perceived risk. (3) Complex retrofit projects on critical facilities that must remain operational are inherently risky to Contractors. After review, it was decided to recommend that the Commission approve
awarding the contract to the lowest responsive responsible bidder. An Agenda Item to award the contract was drafted. A letter seeking general plan conformity determination from Alameda County was submitted. The construction
management and engineering support services are being
evaluated to ensure proper resources are identified and available during construction.

Issues and Challenges:

The budget and schedule forecasts have been updated to
reflect the FY25-34 CIP since last quarterly report. The variance between the approved and forecast budget and
schedule is due to the bid evaluation process, updated
construction contract duration and the high construction contract bids. The construction Notice-to-Proceed is
forecasted to be delayed approximately 3 months due to the time to perform a bid evaluation on the higher-than-expected contract bids. The forecasted construction duration was increased 2 months to match the longer duration included in the contract documents. The project team is currently
developing new project schedule and budget forecasts and Existing Project Site
will report them during the next reporting period.

Contract Monitoring Division goals were issued. The Division 00 and 01 specifications were developed and updated by the project team.

Issues and Challenges:

The budget and schedule forecasts have been updated to
reflect the FY25-34 CIP since last quarterly report. The variance between the approved and forecast project budget and schedule is due to the addition of the Utility Water/Fire Protection System pump station scope. The pump station
design is being developed under SVWTP Ozone project,
while the construction work will be under the SVWTP Short Term Improvements project. The pump station design scope was identified late in the SVWTP Ozone project’s design phase and is lagging behind the Short Term Improvements design. The advertisement date for the SVWTP Short Term Improvements construction contract will consequently be delayed allowing incorporation of the pump station scope into the bid package.

10037350 - Regional Groundwater Treatment Improvement
Project
Description: The purpose of this project is to improve the performance of the Regional Groundwater Wells and treatment systems in the South Westside Basin for reliable use during dry years. In normal and wet years, the SFPUC will supply treated surface water to Daly City, San Bruno, and Cal Water to be used in place of their typical groundwater supply, thereby increasing the volume of groundwater in storage that can be pumped as supplemental water in dry years. This project will address emerging well water quality issues that require treatment, will provide additional reliability for treatment systems at the wells, and will evaluate the potential for a consolidated treatment facility (through Alternatives Analysis only).

If a centralized treatment alternative is selected, the estimated project cost could potentially be $250 million, which includes construction of approximately 14 miles of 8" to 24" diameter pipeline, a pump station, storage tanks, treatment facilities, and other ancillary facilities. This project will build auxiliary water treatment facilities as well as other enhancements to increase the reliability and efficiency for maintenance and operation of the well stations.

anticipated during the next quarter.

Issues and Challenges:

The budget and schedule forecasts have been updated to
reflect the FY25-34 CIP since last quarterly report. The variance between the approved and forecast project budget and schedule is due to additional time needed to procure materials during construction and the forecast cost will be increased due to the bids coming in over the engineer's estimate. The scope variance is due to the addition of the programmable logic controller which was previously included in a different project, as well as additional safety and code requirements to commission the Dechlorination Facility. In addition, a new carrier water source is being included to streamline the operation effort required for return to service operations before and after Hetch Hetchy system shutdowns due to the Treated Water Reservoir (TWR) currently
supplying the carrier water system. Currently, after 5 weeks of operation the TWR would be depleted, and a refill
operation would be required. The new carrier water source would be a direct source, which would allow the TWR to be able to feed the system in parallel.

10035029 - As-Needed Pipeline Repairs
Project
Description: Water Supply and Treatment Division's (WSTD) maintenance and inspection program inspects the regional pipeline system on an ongoing basis. However, when repairs are identified to be needed following inspections and when emergency repairs are needed, a contractor is not readily available to perform the repairs. This project will increase system reliability by reducing the duration and number of outages since a pre-qualified, as-needed contractor will be available to complete repairs immediately following inspections or in emergencies. This project will repair/replace regional pipeline segments that will be inspected over the next five years, in addition to any emergency repairs that may be needed.

The initial construction contract will be 3 years and combined with Project 10036840, BDPL1-4 Lining Repair to provide a sufficient guaranteed scope.

23 I. Regional WECIP Quarterly Report Q3-FY2023-2024 (01/01/24 - 03/31/24) 10036839 - BDPL4 PCCP Repair
Project Description: Historically,
when pre-stressed concrete cylinder pipe (PCCP) fails due to breaks in the spirally wound wire, the high-pressure failure can have catastrophic consequences. Some segments of the Regional Water System are constructed of PCCP. From recent inspections of Bay Division Pipeline No. 4 (BDPL4) Segment D, constructed of PCCP, a large number of wire breaks and circumferential cracks were found in the last 1.25 miles of pipeline that parallels Edgewood Road in Redwood City. In addition, several leaks have surfaced at circumferential cracks and where the pipeline transitions from PCCP to steel. Segments where wire breaks are concentrated will need to be repaired/replaced to prevent catastrophic failure and circumferential cracks and leaks will also be repaired. The first phase of this project will be to repair segments where there are high concentrations of wire breaks, wide circumferential cracks and active leaks. This first phase will include planning, design and construction of repairs. The second phase of the project will be to address the remaining

1.25 miles of pipeline, which includes planning, design and partial encumbrance of a construction contract. The project budget will be reevaluated following completion of the Alternatives Analysis for the second phase. The first construction contract will increase system reliability by rehabilitating approximately 650 feet of 84-inch diameter BDPL4 PCCP in Redwood City.

circumferential cracks, and active leaks.

Phase 2 will be to evaluate and address the wire breaks and circumferential cracks in the remaining 1.3 miles of BDPL4 PCCP. Phase 1: A Conceptual Engineering Report was
drafted assuming that replacing defective sections with welded steel pipe would be the preferred method for repairs.

However, the project team is continuing to analyze alternative methods of repair such as an internal Carbon Fiber
Reinforced Polymer (CFRP) repair due to the high estimated cost to replace with welded steel pipe. Phase 2: A Needs Assessment Report (NAR) was circulated for review, and
additional modeling was completed to address comments.

When the NAR is finalized, this phase 2 project will be placed on hold with planning scheduled to resume in 2026 in order to focus on Phase 1.

Issues and Challenges:

The schedule forecast has been updated to reflect the
FY25-34 CIP since last quarterly report. The variance
between the approved and forecast project schedule is due to splitting this project into two phases as discussed above.

Phase 2 planning will begin in 2026 and be completed in 2029.

37 I. Regional WECIP Quarterly Report Q3-FY2023-2024 (01/01/24 - 03/31/24) 10015128 - Millbrae Yard Laboratory and Shop Improvements Project Description: SFPUC
has determined that the existing Millbrae Administration Building must remain operational following a major earthquake, and therefore needs to be retrofitted or replaced to meet essential facility requirements.

SFPUC also wants to expand the existing Millbrae Administration Building to merge and house the Water Enterprise staff and equipment from the Rollins Road Facility. This project is necessary to provide Water Enterprise personnel a long term and sustainable campus, and allow the consolidation of work groups for increased staff efficiency. This project will also alleviate shortage of program space, increase efficiency of operations, improve employee working environment with improved heating, ventilation, and air conditioning, improve employee health and safety, and enhance site and building security. A recent planning study has identified several alternatives to meet the project goals. The selected alternative for the Millbrae Yard campus improvements will be implemented in three phases. Phase 1 includes a new laboratory office and new south shop building to alleviate Water Enterprise undersized and outdated workspaces and desire to relocate mission- critical functions to code-compliant structures. This project will provide additional space in the laboratory building by constructing two additional floors on top of it to accommodate the relocation of all personnel from Rollins Road Facility.

Phase 2 includes demolition of the existing Administration Building and construction of a new consolidated Administration Building adjacent to the new laboratory building to accommodate other Water Enterprise staff. Phase 3 includes new covered storage for materials and equipment. Only the scope of work for Phase 1 will be implemented under this project to meet near-term needs, minimize disruptions to operations, and allow gradual buildout of the master plan to stay within the 10-year CIP budget.

1. CAPITAL IMPROVEMENT PROGRAM DESCRIPTION
The San Francisco Public Utilities Commission (SFPUC) Water Enterprise manages a complex water supply system stretching from the Sierra to San Francisco and featuring a series of reservoirs, tunnels, pipelines, and treatment systems. Two unique features of this system stand out: the drinking water provided is among the highest quality in the world, and water deliveries are made to most customers without the use of power, by gravity flow, while generating power at the same time.

The Local Water System is located primarily within the City and County of San Francisco and consists of water storage and treatment facilities; water transmission and distribution infrastructure; buildings and structures for facilities and employees; communica tions systems; and various lands in the City and County of San Francisco. In addition, the Local Water System includes several other small retail systems in Alameda, Santa Clara and San Mateo Counties where the SFPUC directly retails water to various customers. Groundwater in San Francisco is under the jurisdiction of the SFPUC; the Westside Basin is the only viable aquifer for municipal use. Additionally, the Local Water System includes the Emergency Firefighting Water System (EFWS) used for fire suppression in San Francisco and developer-funded assets that have been conveyed to the SFPUC.

The Local Water Enterprise Capital Improvement Program (Local Water CIP) is a 10-year proposed appropriations plan of scheduled projects to physically improve the system assets and maintain level of service goals. This Local Water CIP is updated every two years (with minor modifications in the off years) and integrated with the SFPUC’s 10-year Financial Plan and rate-setting.

There are seven (7) groupings of projects in the Local Water CIP in addition to a separate set of programmatic projects used for feasibility planning, for future capital projects, and for implementation of permit compliance activities. The categories are:
• Local Water Supply
•Local Water Conveyance/Distribution
•Local Reservoirs and
Tanks Improvements
• Pump Station Improvements
• Automated Water Meter Reading
• Buildings and Grounds Improvements
•Emergency Firefightin
g Water System
Changes to the appro v
ed baseline program, including any changes to continuing projects’ scopes, schedules, and budgets, are proposed as part of the biannually updated 10- year CIP to be adopted by the SFPUC Commission and approved by San Francisco’s Mayor and Board of Supervisors. The proposed revisions to the program become the new baseline for new and continuing projects’ scopes, schedules, and budgets in the beginning of the new fiscal year following SFPUC Commission adoption. 1 II. Local WECIP Quarterly Report Q3-FY2023-2024 (01/01/24– 03/31/24)

2. CAPITAL IMPROVEMENT PROGRAM STATUS
This Quarterly Report presents the progress made on Local Water projects between January 1, 2024 and March 31, 2024. This document serves as the third (3rd) Quarterly Report in Fiscal Year 2023- 2024 (FY24) published for the Water Enterprise Capital Improvement Program.

The 2023 Approved Local Water Enterprise CIP (2023 Local WECIP) has thirteen (13) projects. No Local project is in “Not Initiated“ status.

Figure 2.1 shows the total Current Approved Budget for the Local projects in each phase of the program as of March 31, 2024. The number of projects currently active in each phase is shown in parentheses.

Figure 2.2 shows the number of Local projects in the following phases as of March 31, 2024: Pre- construction, Construction, and Post-construction.

Figure 2.3 summarizes the environmental review status of the Local projects as of March 31, 2024.

The Local Water Conveyance/Distribution System Program has an annual goal to replace or improve a target of 12 to 15 miles of water mains in San Francisco. Figure 2.4 shows the planned and actual miles of pipeline projects that have reached substantial completion since FY20. The forecast mileage for FY24 is 4.5 miles; which is reduced from the target of 15 miles due to a reduction in program budget for FY24.

Water main replacement projects with construction underway in the 3 rd quarter of FY24 include projects in the City streets of L-Taraval Segment B, Diamond Street, Laidley Street, Hampshire Street, Gold Mine Drive, and Joost Street. Water work under Construction Contract WD-2896 on Webster Street is anticipated to start in Q4 FY24. During this reporting period, Construction Contract WD-2720 which includes water, sewer, and paving work on Precita Avenue in the Bernal Heights residential district and Construction Contract WD-2891.A/PW-011 which includes water work on Cesar Chavez advertised with SFPUC Commission and award is anticipated for Q4 FY24.

Figure 2.5 shows the annual total program expenditure by fiscal year for the pipeline replacement program. The budget for FY24 is $51.9M with forecasted expenditures to be $43.2M. The difference between budget and forecast is attributed to encumbering funds for the entire construction contract value for multiple contracts and for several construction contracts that span 2 years or more.

7. PROJECT STATUS REPORT
10033816 - Potable Emergency Firefighting Water System
Project Description: This
project provides funding for the design and construction of about 2 to 3 miles of large diameter earthquake resistant pipeline to improve the fire water and potable supply reliability in the western area of San Francisco, particularly in the Sunset and Richmond Districts. This project is part of a larger effort to construct approximately 14 miles of the Potable Emergency Firefighting Water System (PEFWS), which also includes two planned pump stations. Current funding will fund the aforementioned 2 to 3 miles of pipeline and design work for a Lake Merced Pump Station. The pipeline will be designed as a potable AWSS pipeline, meaning it will convey low pressure potable water with connections to the distribution system during normal operations but can be isolated with motorized valves and operate under high pressure for firefighting after a major seismic event or emergency conditions by activating associated pumps. Funding is provided through FY 28-29. Additional funding will be provided by existing Earthquake Safety & Emergency Response (ESER) general obligation bond funds, with additional funding possibly approved in the March 2020 ESER referendum. $10M in funding was utilized for the Stern Grove Emergency Restoration Contract and is requested to be included back in FY 23-24 funding. The total Local Water funding commitment to this project is $55M with $12M carryover from FY 18-19 and FY19-20 budgets.

Project Description: Since
2000 the SFPUC has replaced the majority of the Town of Sunol pipeline system through the Town of Sunol Fire Suppression project, except for two segments. This project will complete the replacement of the last two segments of the system, by replacing sections of the pipeline that crosses the Arroyo de Laguna Creek (Creek Crossing) and under Highway 680.The upstream section of pipeline that feeds the Town of Sunol is exposed under the creek and in danger of failing under Highway 680. Pipeline failure at either location has significant consequences, since all fire and potable water in the Town of Sunol is dependent on the rehabilitation of this 12-inch diameter line. This project will reduce maintenance from pipe breaks and have less main flushing which may lower impact on operating expenses.

Progress and Status:

During this
reporting period, the project team continued to
make progress towards the bid advertisement package. Real Estate provided the offer package to the Sunol Glen School for the new easement. Coordination with Caltrans continued on a monthly basis to negotiate the impacts within the Arroyo de la Laguna Creek. Environmental permits have been
submitted and discussions with the agencies are ongoing.

There is a delay in completing the bid package, but it is anticipated to be issued for advertisement during the next quarter.

Issues and Challenges:

The budget and schedule forecasts have been updated to
reflect the FY25-34 CIP since last quarterly report. The variance between the approved and forecast project budget and schedule is due to additional coordination effort with Caltrans and environmental permitting. Although the
coordination will likely not take a full year, the project is constrained by performing work during the summer months since a portion of the work crosses the Sunol Glen School, which requires construction to be performed during summer break. There is also new requirement from permitting
agencies that the existing Town of Sunol Pipeline needs to be removed from the creek, which lead to higher escalation costs.

Hampshire Street, Gold Mine Drive, and Joost Street. Water work under Construction Contract WD-2896 on Webster
Street is anticipated to start in Q4 FY24. During this reporting period, Construction Contract WD-2720 which includes water, sewer, and paving work on Precita Avenue in the Bernal
Heights residential district and Construction Contract
WD-2891.A/PW-011 which includes water work on Cesar
Chavez were advertised with SFPUC Commission, and the
award is anticipated for Q4 FY24.

Issues and Challenges:

The budget and schedule forecasts have been updated to
reflect the FY25-34 CIP since last quarterly report. The variance between the approved and forecast project budget and schedule is due to the extended project schedule and providing additional funding for increased focus on the main replacement program due to an increase in main breaks
through the city.

Progress and Status:

The project includes two subprojects: Subproject 1 (A) Vista Grande Drainage Basin Improvement managed by Daly City; and Subproject 2 (B) Lake Merced Recycled Water Diversion - Phase 3. 1) Vista Grande Drainage Basin Improvement
Project (Contract A): SFPUC and Daly City have been in
negotiations with California Coastal Commission (CCC)
regarding draft permit conditions, as well as a request for onsite project mitigation on SFPUC property. Daly City
continues working to ensure project funding is in place and has received a $15M commitment from San Mateo County.

SFPUC staff prepared a final Draft Funding Memorandum of Agreement which is currently under final internal review. 2) Lake Merced Recycled Water Diversion (Contract B): This Phase of work has been delayed as a result of lack of staffing and significant delays for the Westside Recycled Water
Project that would impact availability of recycled water.

The budget and schedule forecasts have been updated to
reflect the FY25-34 CIP since last quarterly report. The variance between the approved and forecast project budget and schedule is due to abatement of past improper charges from Water System Improvement Program groundwater
projects, additional construction contribution to Daly City authorized by SFPUC and increases due to escalation
associated with project delays. The forecasted completion date is delayed as a result of Daly City's challenges with attaining funding and delays with permit approval.

Progress and Status:

This project
includes multiple construction contracts. (A)
Recycled Water Treatment Facility; (B) Pump Station and Reservoir; (C) Pipeline; (D) Irrigation System Retrofit.

Contract A: The majority of construction work at the treatment facility is complete. The re-design of the variable frequency drives (VFDs) was completed and proposed change orders
were issued in February 2024. Contract B: The Contractor continued addressing punch-list and contract closeout items.

The final service agreement and design was received from PG&E on March 12, 2024; the timeline for energization is still unknown. Contract C: is complete. Contract D: The PUC
completed negotiations with the Contractor on the project schedule and change order requests for past work and is moving forward with a final closeout change order. Cross- connection testing of the Golden Gate Park system was
completed, and the final report is being prepared. Contract E is no longer required as PG&E agreed to provide secondary power service to the Pump Station and Reservoir facility.

Issues and Challenges:

The budget and schedule forecasts have been updated to
reflect the FY25-34 CIP since last quarterly report. The scope, schedule and budget have changed primarily due to premature equipment failures at the Recycled Water
Treatment Facility. The VFDs for the reverse osmosis pumps and secondary effluent pumps failed due to environmental conditions and must be replaced; the associated heating, ventilation, and air conditioning (HVAC) systems must also be modified to lessen moisture in the building which led to the equipment failure. The lead time for the VFD equipment is forecasted to be at least eighteen months. In addition, the treatment facility will require an increase in the power capacity allocated to the Oceanside Plant through PG&E, Exterior of Buildings 580 and 581
which will incur an additional project cost. If this increased power is not available once the commissioning process is re- started, a large generator will need to be rented to complete the project. The schedule forecast is increased by only seven months because the schedule had been previously extended to accommodate the timeline for securing a new primary
power service for the Recycled Water Pump Station in
Golden Gate Park as required at that time by PG&E. Since the last CIP, PG&E agreed to provide secondary service to the facility.

During the quarter, the contractor completed the following:
installation of valve control vault roof curbing and access hatches; installation of control valve pipe supports; installation of control vault electrical conduits and control panels; and on- going installation of reservoir roof plywood associated with roof substructure.

The schedule forecast has been updated to reflect the
FY25-34 CIP since last quarterly report. The variance
between the approved and forecast project schedule is due the bypass that will be installed prior to the start of construction to allow for the reservoir to be taken out of service during the entire 24-month construction duration. In addition, there are on-going delays associated with
manufacturing defects of marine grade plywood being
installed for the reservoir roof substructure failure and Pacific Gas and Electric (PG&E) requiring a new service application and associated design due to a previous dispute related to rate tariff. SFPUC has requested that the Contractor
proceed with fabrication of remaining electrical equipment including adding a portable generator auxiliary power feed to the main panel to allow for temporary power connection for startup, testing, and contractor closeout , due to an
unknown service date from PG&E. These on-going delays are currently being evaluated by the project team and
might impact forecast schedule in the future.

Project Description: The City Distribution Division (CDD) tanks and reservoirs that were upgraded during the Water System Improvement Project (WSIP) are currently, or in the very near future, in need of replacement of their exterior coatings and/or roofing. The useful service life of most of these coatings is approximately ten years and many have begun to deteriorate in the last few years due to the harsh marine environment to which they are exposed. This project will provide the R&R funding necessary to maintain these coating and extend the useful service life of these critical assets.

There are three active
subprojects (Subproject A: University
Mound Reservoir North Basin Roof Coating, Subproject B:

Sutro Reservoir Roof Coating, and Subproject C: La Grande Tank Coating). In the future Subproject D for the Local Tank Coatings is planned to be initiated. During the reporting period, the project team continued with preparing the contract for University Mound North Basin roof coating work for
advertisement. A cost estimate to perform a condition
assessment of the interior and exterior coatings at the La Grande tank was previously received and evaluated. Project team is preparing a task order for condition assessment at La Grande Tank.

Issues and Challenges:

The budget and schedule forecasts have been updated to
reflect the FY25-34 CIP since last quarterly report. The variance between the approved and forecast project budget and schedule is due to the added scope to provide future tank and roof coating replacement for all the remaining Local Water tanks and reservoirs. Additional budget was added as a placeholder for this future work. Needs and condition assessments will be performed in the next several years to fully outline the scope, with a more refined cost estimate and schedule based on the priorities.

Project Description: This
project funds long term improvements to the Harding Park Pump Station to increase reliability and correct conditions that have led to the premature corrosion and failure of critical components. The current design places the pumping facility on top of the recycled water reservoir leading to high humidity levels within the facility. This project will seal the reservoir from the pump room, improve the HVAC system for humidity control, and relocate critical electrical panel and components out of the pump room. The project will also modify the current electrical feed to allow for the safe maintenance of the water pump electrical components while leaving the buildings lighting and auxiliary loads powered.

Over twenty projects have been identified to improve the performance and reliability of the Harry Tracy Water Treatment Plant (HTWTP). However, underdrains in two filters in a bank of six have failed since 2019 and replacement of the underdrains is being prioritized to restore the plant's treatment capacity and reliability. The remaining projects will be deferred to future CIP Planning. The scope of work includes the following: • Remove and dispose existing filter media and provide new filter media, • Procure and install new stainless steel filter underdrains for 6 filters, • Modify air distribution piping beneath filter underdrains, • Clean and recoat main air distribution piping, • Demolition work, and • Concrete work 10037350 Regional Groundwater Treatment Improvement
The purpose of this project is to improve the performance of the Regional Groundwater Wells and treatment systems in the South Westside Basin for reliable use during dry years. In normal and wet years, the SFPUC will supply treated surface water to Daly City, San Bruno, and Cal Water to be used in place of their typical groundwater supply, thereby increasing the volume of groundwater in storage that can be pumped as supplemental water in dry years. This project will address emerging well water quality issues that require treatment, will provide additional reliability for treatment systems at the wells, and will evaluate the potential for a consolidated treatment facility (through Alternatives Analysis only). If a centralized treatment alternative is selected, the estimated project cost could potentially be $250 million, which includes construction of approximately 14 miles of 8" to 24" diameter pipeline, a pump station, storage tanks, treatment facilities, and other ancillary facilities. This project will build auxiliary water treatment facilities as well as other enhancements to increase the reliability and efficiency for maintenance and operation of the well stations.

10034578 CSPL2 Reach 5 Lining Replacement
Crystal Springs Pipeline No. 2 (CSPL2) runs from Crystal Springs Pump Station to University Mound Reservoir. It delivers potable and emergency water supply to San Francisco and to several cities along the Peninsula. Reach 5 of CSPL2, 60" in diameter, from Millbrae Yard to Baden Pump Station (approximately

3.8 miles) in the cities of South San Francisco and San Bruno is over 80 years old and has extensive lining failures. This project would replace approximately 3.8 miles of coal tar lining with cement mortar lining (CML), upgrade 34 appurtenances to meet current standards, and improve access and shutdown flexibility for maintenance by installing 5 manway structures and one 60" diameter valve on CSPL2 and one 48" diameter valve on San Andreas Pipeline No. 1 (SAPL1) near Baden Pump Station. In addition, a recent corrosion investigation found a segment of the CSPL2 to be severely corroded across from the Baden Pump Station due to a gas pipeline crossing and will need to be replaced. Since the Sunset Supply Pipeline, San Andreas Pipeline No. 2, and San Andreas Pipeline No. 3, run parallel to the CSPL2 and are crossed by the gas pipeline, a corrosion investigation will be performed to determine if corrosion has occurred on these pipelines and if any repairs are needed. The scope of work includes the following: • Complete removal of coal tar lining • Installation of cement mortar lining • Installation of manway structures • Procurement and installation of isolation valves • Upgrade of appurtenances such as blow-offs, air release valves, etc. to meet current standards • Replacement of pipeline segments • Traffic control • Pavement restoration work 10035029 As-Needed Pipeline Repairs
Water Supply and Treatment Division's (WSTD) maintenance and inspection program inspects the regional pipeline system on an ongoing basis. However, when repairs are identified to be needed following inspections and when emergency repairs are needed, a contractor is not readily available to perform the repairs. This project will increase system reliability by reducing the duration and number of outages since a pre-qualified, as-needed contractor will be available to complete repairs immediately following inspections or in emergencies. This project will repair/replace regional pipeline segments that will be inspected over the next five years, in addition to any emergency repairs that may be needed. The initial construction contract will be 3 years and combined with Project 10036840, BDPL1-4 Lining Repair to provide a A3

10036839 BDPL4 PCCP Repair
Historically, when pre-stressed concrete cylinder pipe (PCCP) fails due to breaks in the spirally wound wire, the high-pressure failure can have catastrophic consequences. Some segments of the Regional Water System are constructed of PCCP. From recent inspections of Bay Division Pipeline No. 4 (BDPL4) Segment D, constructed of PCCP, a large number of wire breaks and circumferential cracks were found in the last

1.25 miles of pipeline that parallels Edgewood Road in Redwood City. In addition, several leaks have surfaced at circumferential cracks and where the pipeline transitions from PCCP to steel. Segments where wire breaks are concentrated will need to be repaired/replaced to prevent catastrophic failure and circumferential cracks and leaks will also be repaired. The first phase of this project will be to repair segments where there are high concentrations of wire breaks, wide circumferential cracks and active leaks.

This first phase will include planning, design and construction of repairs. The second phase of the project will be to address the remaining 1.25 miles of pipeline, which includes planning, design and partial encumbrance of a construction contract. The project budget will be reevaluated following completion of the Alternatives Analysis for the second phase. The first construction contract will increase system reliability by rehabilitating approximately 650 feet of 84-inch diameter BDPL4 PCCP in Redwood City and includes the following work: • Excavation, shoring, backfilling, and compaction • Demolition of PCCP • Replacement of approximately 530 feet of pipeline by open trench • Slip lining approximately 120 feet of pipeline • Protecting sensitive (wetland and creek) areas and utilities/infrastructure • Traffic control • Site/vegetation and paving restoration

SFPUC also wants to expand the existing Millbrae Administration Building to merge and house the Water Enterprise staff and equipment from the Rollins Road Facility. This project is necessary to provide Water Enterprise personnel a long term and sustainable campus, and allow the consolidation of work groups for increased staff efficiency. This project will also alleviate shortage of program space, increase efficiency of operations, improve employee working environment with improved heating, ventilation, and air conditioning, improve employee health and safety, and enhance site and building security. A recent planning study has identified several alternatives to meet the project goals. The selected alternative for the Millbrae Yard campus improvements will be implemented in three phases. Phase 1 includes a new laboratory office and new south shop building to alleviate Water Enterprise undersized and outdated workspaces and desire to relocate mission-critical functions to code-compliant structures. This project will provide additional space in the laboratory building by constructing two additional floors on top of it to accommodate the relocation of all personnel from Rollins Road Facility. Phase 2 includes demolition of the existing Administration Building and construction of a new consolidated Administration Building adjacent to the new laboratory building to accommodate other Water Enterprise staff. Phase 3 includes new covered storage for materials and equipment. Only the scope of work for Phase 1 will be implemented under this project to meet near-term needs, minimize disruptions to operations, and allow gradual buildout of the master plan to stay within the 10-year CIP budget. The Phase 1 scope includes construction of 68,095 square foot 3-story laboratory building and 12,800 square foot shop building, renovation of an existing 7,440 square foot warehouse, and site improvements such as driveways, hardscape, landscape, and parking (approximately 400 spaces).
10034825 Millbrae Security Upgrades
Millbrae Yard is currently vulnerable to unauthorized intrusion, trespassing, theft, vandalism and physical damage. Site concerns include lack of adequate fencing around the perimeter of the site, lack of electronic security measures to monitor and control access into the Administration Building during normal business hours and after hours, lack of video surveillance to monitor the secure areas within the fenced perimeter, and lack of a physical barrier separating access to the shops/yard areas from visitor parking. This project would address the security concerns and would enhance the overall physical and electronic security components of the Millbrae Yard.

APPENDIX A. PROJECT DESCRIPTION

WATER LOCAL
Water Transmission
10033816 Potable Emergency Firefighting Water System
This project provides funding for the design and construction of about 2 to 3 miles of large diameter earthquake resistant pipeline to improve the fire water and potable supply reliability in the western area of San Francisco, particularly in the Sunset and Richmond Districts. This project is part of a larger effort to construct approximately 14 miles of the Potable Emergency Firefighting Water System (PEFWS), which also includes two planned pump stations. Current funding will fund the aforementioned 2 to 3 miles of pipeline and design work for a Lake Merced Pump Station. The pipeline will be designed as a potable AWSS pipeline, meaning it will convey low pressure potable water with connections to the distribution system during normal operations but can be isolated with motorized valves and operate under high pressure for firefighting after a major seismic event or emergency conditions by activating associated pumps. Funding is provided through FY 28-29. Additional funding will be provided by existing Earthquake Safety & Emergency Response (ESER) general obligation bond funds, with additional funding possibly approved in the March 2020 ESER referendum. $10M in funding was utilized for the Stern Grove Emergency Restoration Contract and is requested to be included back in FY 23-24 funding. The total Local Water funding commitment to this project is $55M with $12M carryover from FY 18-19 and FY19-20 budgets. 10033818 Town of Sunol Pipeline
Since 2000 the SFPUC has replaced the majority of the Town of Sunol pipeline system through the Town of Sunol Fire Suppression project, except for two segments. This project will complete the replacement of the last two segments of the system, by replacing sections of the pipeline that crosses the Arroyo de Laguna Creek (Creek Crossing) and under Highway 680. The upstream section of pipeline that feeds both the potable line and fire suppression line to the Town of Sunol is exposed under the creek and in danger of failing under Highway 680. Pipeline failure at either location has significant consequences, since all fire and potable water in the Town of Sunol is dependent on the rehabilitation of this 12" line. This project will reduce maintenance from pipe breaks and have less main flushing which may lower impact on operating expenses. This project is broken up into two portions and the scope of work will include the following:

Creek Crossing: Replace approximately 550 feet of 12" diameter pipeline crossing Arroyo de Laguna Creek with 12" diameter Ductile Iron Pipe (DIP) class 53 - Open cut trench across the creek - New tie in points with gate valves - Creek restoration and tree removal in pipeline alignment and removal of existing Town of Sunol pipeline within the creek from bank to bank. Highway 680 Crossing: MOU agreement with Alameda County Transportation Commission (ACTC) to replace existing 12" diameter Town of Sunol pipelines under Highway 680 for $1.3M
19063 Local Water Conveyance/Distribution System
This long-term program funds management of linear assets in the potable water distribution system between transmission or storage and final customer service connection. Main Replacement Program:
replaces and renews feeder and distribution mains for the 1,230 miles of pipe distribution system.

Improvements include replacement, rehabilitation, relining, and cathodic protection of all pipe size categories to extend or renew pipeline useful life. Coordination with construction projects by other City agencies, especially SFPUC Sewer and DPW Paving, is emphasized to optimize efficiencies and minimize customer disruptions. In FY21-22, a new Joint Transit Project was created to provide separate funding for the main replacement project along major transit corridor including L-Taraval, Geary, and N-Judah, where street improvement projects by other agencies (CalTrans, SFMTA, SFCTA, DPW) and are more expensive to A9
APPENDICES Q3-FY2023-2024 (01/01/24 – 03/31/24)
implement due to their complexity, traffic and transit impacts, and multi-agency coordination. Phase A construction of the L Taraval Project is completed and Phase B construction is currently underway with a completion in FY24-25. Geary BRT Phase 2 (32nd Ave to Stanyan Street) is anticipated to start construction in FY24-25. The Joint Transit Project will provide separate project funding at a cost of $8.6M per mile. Additionally, In FY21-22 a new Better Market Street Project was created to provide separate funding for the water main replacement along the Market Street Corridor. Due to the concerns over construction impacts and overall project costs, design and initial funding for 0.5 miles is provided for FY23-24 and FY24-25 only. The budget will include the following: 1) replacement of distribution pipelines at $5.8M per mile; 2) replacement of 1 mile with seismically reliable pipelines at $8.6M per mile; and 3) Pipe relining at $4.3M per mile. The funding for FY23-24 and FY24-25 will provide funding for design and construction of 5.9 to 6.3 miles per year. The overall main replacement program will include design and construction funding for FY23-24 and FY24-25 of 7.5 to 9 miles per year when including the Joint Transit, Better Market Street Projects, and Potable Emergency Firefighting Water System. 10036916 Lead Component Service Program
In September 2016, the California State Legislature passed Senate Bill 1398 (SB 1398) requiring all public water systems to compile an inventory of known lead user service lines in use in its distribution system and identify areas that may have lead user service lines. In addition, SB 1398 requires public water systems to provide a timeline to the board for the replacement of user service lines whose content cannot be determined. This new CIP program funds the management of and replacement of a.) Unknown user service lines, and b.) Galvanized service lines with possible lead whips or appurtenances over a 10-year period: a.) Unknown user service lines: There are 10,912 unknown user service lines. CDD has field investigated 900 unknown user service lines distributed throughout the City and based upon a recommended statistical analysis, approximately 4% (36) of the 900 have been identified as galvanized. The new CIP program will continue the discovery of the remaining 10,012 service lines through consultant services over a 2-year period at a cost of approximately $1 million/year. In addition, the program estimates that approximately 15% (1,640) of the unknown service lines will need to be renewed; however, this figure may change depending on the results of the discovery process: $2.0M over 2 years to determine the service line material for unknown services, $24.6M over 10 years to renew approximately (15%) 1,640 services potentially found to have a galvanized service. Although only 4% of unknown services have currently been found to be galvanized, this new CIP program is projecting that conservatively 15% of unknown services will be renewed. b.) Galvanized service lines: There are 4,524 galvanized services with a potential lead whip or appurtenances. Currently, CDD has field inspected 200 galvanized services and 20% are galvanized with the remaining 80% consisting of another material. Based on this, the new CIP program will fund the continuation of field investigations as well as the service renewal of 30% (1,360) galvanized services over a 10-year period; $1.0M over 2 years to confirm the service line material for galvanized services; $20.4M over 10 years to renew 1,360 galvanized services. Although only 20% of galvanized services have been found to be galvanized, this new CIP program is projecting that conservatively 30% of the services will be found to actually be galvanized.

An addiitional $6.5M is added in FY23-24 for replacement of roof substructure including all wood joists and plywood sheating which were inspected during construction and found to be in need of replacement. 10037794 Reservoir Roof and Tank Coatings
The City Distribution Division (CDD) tanks and reservoirs that were upgraded during the Water System Improvement Project (WSIP) are currently, or in the very near future, in need of replacement of their exterior coatings and/or roofing. The useful service life of most of these coatings is approximately ten years and many have begun to deteriorate in the last few years due to the harsh marine environment to which they are exposed. This project will provide the R&R funding necessary to maintain these coating and extend the useful service life of these critical assets.

Pump Stations
10015231 Harding Park PS
This project funds long term improvements to the Harding Park Pump Station to increase reliability and correct conditions that have led to the premature corrosion and failure of critical components. The current design places the pumping facility on top of the recycled water reservoir leading to high humidity levels within the facility. This project will seal the reservoir from the pump room, improve the HVAC system for A11
APPENDICES Q3-FY2023-2024 (01/01/24 – 03/31/24)
humidity control, and relocate critical electrical panel and components out of the pump room. The project will also modify the current electrical feed to allow for the safe maintenance of the water pump electrical components while leaving the buildings lighting and auxiliary loads powered. In addition, the proprietary WaterTronics control panel is proposed to be replaced by a more standard PLC that can be modified by SFPUC if needed.

Buildings and Grounds
10037249 New CDD Headquarters
The City Distribution Division (CDD) Headquarters, currently located at 1990 Newcomb Avenue, San Francisco, was constructed in 1962. The majority of CDD's staff are located at Newcomb (approx. 260 people). Existing facilities include administrative offices, warehouse, shops, materials and equipment storage and vehicle fleet. CDD oversees the retail water distribution system with the City and County of San Francisco, responsible for the physical infrastructure of San Francisco's potable, auxiliary water system, groundwater, and recycled water systems.

Emergency Firefighting Water System
EFWS PL - EFWS Pipelines
The Emergency Firefighting Water System(EFWS) includes several methods of delivering water to suppress fires during emergency situations. EFWS is vital for protecting against the loss of life, homes, and businesses from fire following an earthquake and non-earthquake multiple-alarm fires. One EFWS component is a high-pressure fire-suppression water system, formerly known as Auxiliary Water Supply System (AWSS), which was originally built in the decade following the catastrophic 1906 San Francisco earthquake. It consists of a resilient 135-mile high-pressure pipeline network, a high elevation reservoir, two large capacity tanks, two high-pressure seawater pumping stations, and manifolds that allow fireboats to inject Bay water into the City’s pipelines. The Potable Emergency Firefighting Water System (PEFWS) will bring a seismically resilient high�pressure firefighting water system to the western neighborhoods of San Francisco, while also creating a seismically resilient pipeline that supplies drinking water to the west side during non�fire situations. The proposed overall project will install over 14 miles of seismically resilient pipelines in multiple phases as funding is provided. The system will be capable of providing water to the SFFD firefighters at the high pressure needed to combat large fires after a seismic event. The proposed pipelines will be fed by pump stations delivering 30,000 gallons per minute with services to the Richmond and Sunset Districts. Fireboat manifolds allow fire boats to pump seawater from the bay into the EFWS.

Existing fireboat manifolds at Fort Mason and Pier 33 ½ are located on piers of unknown condition and are likely susceptible to seismically induced failures. Rehabilitation of manifolds and connector pipelines is required at Fort Mason and Pier 33 ½ to provide adequate access for firefighters.

EFWS PS - EFWS Pump Station
The Emergency Firefighting Water System (EFWS) includes several methods of delivering water to suppress fires during emergency situations. EFWS is vital for protecting against the loss of life, homes, and businesses from fire following an earthquake and non-earthquake multiple-alarm fires.
