RE: Wastewater Enterprise Capital Improvement Programs
2nd Quarter/ Fiscal Year 2025-2026
Enclosed please find the Wastewater Enterprise Capital Improvement Programs (WWE CIP) Quarterly Report for the 2 nd Quarter (Q2) of Fiscal Year (FY) 2025-2026. The primary intent of this report is to provide the Commission, stakeholders, and the public a status summary of the Program for the period of October 1, 2025 to December 31, 2025.

As part of the mid-cycle budget update to the 10-Year Capital Plan for FY2025-26 to FY2034-35 that was adopted by the Commission on February 11, 2025, the Biosolids Digester Facilities Project’s (BDFP’s) budget was increased from $2,672.62M to $2,837.14M. The SSIP Phase 1 Approved budget has increased by $164.52 million due to
this change. The Current Approved Budget reflects the Commission approved FY2026 through FY2035 mid-cycle budget.

The Approved Budget for the R&R Collection Systems- Large Diameter Program was inadvertently overstated as $105.7M and the R&R Treatment Facilities was understated as $221.6M in the previous quarterly report. The correct Approved Budgets are $98.4M and $270.6M, respectively. This report reflects the correct value.

Quarterly Report Format Changes
In response to the U. S. Department of Justice’s requirement that all public documents be digitally accessible to individuals with disabilities by April 24, 2026, staff implemented the following revisions to the Wastewater Enterprise (W WE) Quarterly Reports, beginning with the Q2 FY2025-2026 report:
• Removed pie charts, schedule and cost bar charts, and photographs, and replaced with text and tables.
• Refreshed format to improve readability, consistency, and accessibility while

focusing on the program information that changes most meaningfully from quarter to quarter. The revisions also support a more efficient repeatable process for producing the report each quarter using standardized data sources. • Combined the reporting for the following WWE Programs: Sewer System Improvement (SSIP), Facilities and Infrastructure (F&I) and WWE R&R all WWE CIP projects, which is in alignment with SFPUC’s evolution towards a Rolling 10- year CIP approach.
• Removed the following tables: “Budget and Schedule Trend Summary”, “Project Performance Summary”, “Ongoing Construction”, “Project in Closeout”, and “Completed Projects.”
• Organized to cover all WWE Programs, and includes these overall sections: 1) Quarter in Review 2) Program Performance, 3) Project Status Report, and 4) Appendices.
• Added the following two tables:
o Table 1.1, “Project Milestones Achieved During Quarter” o Appendix B, “Approved Project Budget and Schedule”.

The report complies with emerging Americans with Disabilities Act (ADA) accessibility requirements for published documents.

Program Quarterly Report
Quarter 2, Fiscal Year 2025-2026, October 2025 - December 2025 About this report
The Wastewater Enterprise CIP Quarterly Report provides a consistent, transparent, and accessible snapshot of progress on major wastewater capital projects during the reporting quarter. Its purpose is to inform the SFPUC Commission, Finance stakeholders, and the public on how the program is performing against approved scope, budget, and schedule; highlight notable accomplishments and near-term priorities; and summarize key delivery considerations being actively managed.

This report has been updated to improve clarity, consistency, accessibility, and efficiency of production.

The revised format emphasizes information that meaningfully changes on a quarterly cadence and supports a repeatable publication process using standardized data sources.

To align with SFPUC’s evolving Rolling CIP approach, while maintaining consistency with the Commission-approved 10-year CIP, the quarterly report continues to present program-level performance using the adopted CIP baseline. The report narrative and highlights are oriented toward current delivery priorities and upcoming work, while ensuring that reported “Approved” totals remain directly traceable to the approved CIP.

As part of SFPUC’s normal two-year budgeting cycle, the Commission-adopted CIP baseline is refreshed to reflect the current program plan and reporting horizon. Using that updated baseline for quarterly reporting maintains clear alignment between the report and the adopted CIP and reinforces a Rolling CIP focus on active delivery and upcoming work, while preserving a consistent record of program performance.

For reliability and consistency, the report uses standardized definitions for terms such as project phase, approved budget, forecast, and expenditures to date. Where the same value appears in multiple places, it is sourced from the same underlying dataset and inserted through a repeatable process to minimize manual reconciliation.

This report is designed to be accessible to a broad audience, including readers using assistive technologies. Accessibility considerations include structured headings, readable tables, meaningful link text, and alternative text for images. Graphics and photos are included only when they improve understanding and can be maintained accessibly on a quarterly basis.

The Executive Summary provides a brief snapshot and selected highlights. The body of the report provides supporting detail organized by quarterly accomplishments, program performance, and project- level status summaries.
2 Ab out This Report | WWE-CIP Quarterly Report | Q2-FY2025-2026 (10/01/25–12/31/25) This report includes the following sections:
• Section 1 – Quarter in Review
• Section 2 – Program Performance
• Section 3 – Project Status Report
• Appendices
This Executive Summary provides a brief snapshot of Wastewater Enterprise capital program performance for the reporting quarter, including overall cost and schedule status, key accomplishments, and notable delivery considerations. Additional project details are provided in the following sections and in the Project Status Report.

How to read cost and schedule information
• Cost figures are typically shown in millions of dollars, and represent approved budgets, current forecasts, and actual expenditures to date for the reporting period. • Schedule information focuses on project phase, key milestones, and forecast completion dates. • Variance between approved, forecast, and actual values indicate where work is ahead of plan, on track, or requires additional management attention.

Data sources and timing
Unless otherwise noted, cost and schedule data are drawn from SFPUC’s financial and project management systems as of the end of the reporting period. Because some figures are rounded and certain project statuses may change after the data “as-of” date, the report should be used as a snapshot in time.
3 Executive Summary | WWE-CIP Quarterly Report | Q2-FY2025-2026 (10/01/25–12/31/25) Executive Summary
This Quarterly Report provides a summary update of the Wastewater Enterprise (WWE) Capital Programs that include capital as well as repair and replacement projects. The three WWE programs are: (1) the Sewer System Improvement Program (SSIP), (2) WWE Facilities and Infrastructure Program (F&I), and (3) the WWE Renewal and Replacement Program (R&R).

The SSIP is further divided into SSIP Phase 1 and Other SSIP because of program re-baselining and the evolution from a fixed program (SSIP Phase 1) to a “rolling” capital program. F&I projects are those capital projects outside of the original SSIP, because of type, location or timing of projects. The rolling CIP includes SSIP and F&I projects. R&R is an ongoing annual program that addresses deficiencies in the wastewater collection and treatment systems.

ES 1.1 Rolling 10-year CIP Cost and Schedule Snapshot
The following Tables provide a summary of the cost and schedule snapshot for the rolling capital projects. For this Quarterly Report, the schedule and cost forecasts for projects in the rolling CIP were updated to match the proposed schedules and costs in the upcoming FY27-FY36 10-year Capital Improvement Plan (CIP) that will be presented to the San Francisco Public Utilities Comm ission in February 2026. The forecasts reflect updated cost assumptions, updated cost and schedule estimates, and refined scopes of work for multiple projects in the rolling CIP, and project level details can be found in Section 2 of this report.

As part of the mid-cycle budget update to the 10-Year Capital Plan for FY2025-26 to FY2034-35 that was adopted by the Commission on February 11, 2025, the Biosolids Digester Facilities Project’s (BDFP’s) budget was increased from $2,672.62M to $2,837.14M. The SSIP Phase 1 Approved budget has increased by $164.52 million due to this change. In the tables below, the Current Approved Budget reflects the Commission approved FY2026 through FY2035 mid-cycle budget.

For this Quarterly Report, the schedule and cost forecasts for projects in the rolling CIP were updated to match the proposed schedules and costs in the upcoming FY27-FY36 10-year Capital Improvement Plan (CIP) that will be presented to the San Francisco Public Utilities Commission in February 2026.

10 Program Performance | WWE-CIP Quarterly Report | Q2-FY2025-2026 (10/01/25–12/31/25)

2. Program Performance
This section provides a high-level view of cost and schedule performance for the Wastewater Capital Program, using the Commission-adopted CIP baseline as the reference point. It summarizes approved budgets, current forecasts, and expenditures to date, along with key schedule indicators, to show how projects are progressing relative to planned delivery. Performance is presented in a way that supports quarterly oversight and highlights material changes and trends that inform near-term delivery focus.

As part of the mid-cycle budget update to the 10-Year Capital Plan for FY2025-26 to FY2034-35 that was adopted by the Commission on February 11, 2025, the Biosolids Digester Facilities Project’s (BDFP’s) budget was increased from $2,672.62M to $2,837.14M. The SSIP Phase 1 Approved budget has increased by $164.52 million due to this change.

Progress and Status:

Note regarding the Key Milestones table (above): It was determined that upgrades to the Distributed Control System (DCS) primarily involve computer hardware and software which do not fall within the definition of a "project" under the California Environmental Quality Act (CEQA) because there would be no physical change in the environment. The project delivery method for this project is Progressive Design-Build with pre-design and design components. Construction Notice-to-Proceed represents the start of fabrication manufacturing. DCS design at Oceanside Water Pollution Treatment Plant (OSP) was initiated this quarter. Meanwhile, new DCS network design in SEP is almost complete and is expected to finish in the next quarter. Manufacturing of DCS hardware and various related equipment onsite and coordination with the BDFP team continued this quarter. As part of the 10-Year CIP effort, it has been proposed to consolidate the scope of work of three other DCS capital projects into this project.

Issues and Challenges:

The variance in the project budget and schedule is the result of consolidating the scope of work that used to be covered under multiple DCS capital projects. This consolidation effort meanwhile resulted in the early closeout and budget reduction under the three other capital projects.

The original project also included relocation assistance associated with temporary displacements of existing lease-holders who occupy SFPUC's property above the C-Box Transport Storage Structure (Lot 031), as this space was needed for construction staging. Due to various challenges with implementing the original scope of work, the project team re-evaluated various potential alternatives. Based on the re- evaluation and additional hydraulic modeling work, a more cost-effective solution that involves a weir modification to the existing system was determined to provide significant improvements to the conveyance capacity. The scope of this project is now the implementation of this weir modification. After this project is completed, staff will observe the system performance and determine if additional work is needed and if a separate project would be recommended for initiation in the future.

At the end of the planning effort, the two projects will be completed through a separate wastewater capital project, the Large Diameter Sewer Rehabilitation and Condition Assessment. When this project is completed, approximately 4,350 feet of large-diameter sewers will be rehabilitated, with useful life extended by at least 50-years.
10002554 Richmond Transport Modeling
The project has been completed. Historically, geysering and blown manholes have been observed in the Richmond Transport/Storage Tunnel and upstream sewer system during large storms. Various hydraulic models were performed using InfoWorks and some physical improvements to the system have been made over the last 15 years. The hydraulic modeling performed could not account for air pockets or potential hydraulic bores in the system; therefore, WWE and DPW/Hydraulics agreed that consultant support was needed to provide numeric modeling that can stimulate the known situation and provide recommendations for capital improvements to address the system issues. This project included the review of two separate models: the InfoWorks Integrated Catchment Model of the San Francisco collection system, and a Transient Analysis Program model of the Richmond Transport/Storage Tunnel and associated sewers and amenities. Recommendations for improving the system and

22 Appendix A | WWE Quarterly Report | Q2-FY2025-2026 (10/01/25–12/31/25) addressing the identified issues were developed in a technical memorandum. Since the completion of the Technical Memo (TM), a new project was initiated to evaluate and determine which recommendations from the TM will be implemented through construction. 10002641 Collection System Condition Assessment
This project has been completed. There are over 80-miles of major sewers that have been in service for over 100-years. Using Collection System Asset Management Program (CSAMP) data, major sewers were prioritized by expanding the existing consequence of failure scores.

Using this method, staff identified approximately 13-miles (out of the 80-miles) of major sewers that were considered to be the most critical with an average age of 127-years. The project completed the condition assessment of approximately 10-miles of these critical large- diameter sewers. The project included condition assessment of large-diameter sewers at various locations throughout San Francisco and conducting the Needs Assessment effort for the Planning Phase. Upon completion of the condition assessment, the means and methods of rehabilitation or replacement will be determined and SSIP sewer improvement projects initiated.
10002689 Drumm and Jackson Streets Sewer System Improvement This project has been completed. Under this project, 800 linear-feet of the Drumm Street Box Sewer (between Commercial and Jackson Streets) and 200 linear-feet of the Jackson Street Box Sewer (between Drumm Street and the Embarcadero) was rehabilitated. Increasing the reliability of these major assets helps meet the NPDES permit requirement to maximize use of the collection system for storage and to maximize flows to the wastewater treatment plant.

Associated work for rehabilitation included performing necessary cleaning for trenchless rehabilitation, bypassing sewer flow by damming and piping through the existing box sewer and performing surface restoration. Coordination with WWE was conducted to ensure worker safety and prevent wet-weather impacts. CEQA approval and public outreach for the project were completed. The project included planning, environmental approval, design, and construction phases.
10002760 Cargo Way Sewer Box Odor Reduction
This project has been completed. This project will construct a new force main (flush line) that conveys secondary effluent from the existing Booster Pump Station to the existing 7-foot diameter sewer located on Cargo Way, near Mendell Street. The new force main will introduce approximately 1.5 million-gallon-per day (MGD) of flow back into the sewer system to minimize solids from settling to the bottom of the sewer; thereby, reducing odors from forming and escaping from the sewers into the atmosphere. In addition, mechanical, electrical, and instrumental controls will be installed inside the Booster Pump Station that would allow operation staff to turn on and off (or throttle) flows into this flush line. 10002767 Rutland Sewer Improvements
Project Completed. Under this project, the hydraulic capacity of the sewers in the project area increased to meet the SSIP Level of Service storm. The project consisted of multiple

23 Appendix A | WWE Quarterly Report | Q2-FY2025-2026 (10/01/25–12/31/25) improvements along Rutland Street (from Visitacion Avenue to Sunnydale Avenue) including replacing the existing sewer with a larger reinforced concrete pipe, constructing a wet weather diversion structure, and conveying water passing over a weir inside this underground structure during a large storm event through new piping and discharging into a deep wet weather tunnel (Sunnydale Sewer Tunnel). To minimize construction impacts to the community, this sewer work was constructed with the Visitacion Valley Green Nodes Project. 10029734 Land Reuse of 1801 Jerrold Avenue
This project includes the acquisition of this site for SFPUC both near-term and long-term use.

This 1.54-acre site is currently under the jurisdiction of the Department of Public Works. It was formerly used as an asphalt plant that has not been operational for many years. Acquisition of the site by the SFPUC would be beneficial because there are very few empty or underutilized sites around the SEP; and, after completion of any necessary planning and environmental review, this site can serve a variety of functions to support the SEP's short and long term efforts.

10041814 Griffith DW FM Rehab
This project involves condition assessment and rehabilitation of the Griffith dry weather force main. It is recommended that a complete CCTV inspection is performed as the 2017 inspection was only partially performed due to standing water in the pipeline. Although rehabilitation is a potential option and should be explored in Planning & Design, the project cost assumes an in-kind replacement of the entire length (640 LF) of existing dry weather force main.
10042116 Sunnydale PS & FM Improvements - Phase A
This project addresses the longer-term improvements to meet the Operational Reliability LOS goal (state of good repair) and should be coordinated with the preceding Sunnydale PS Safety Improvements project (PS-3). The scope of this project includes: 1. Renew protective coatings on the discharge piping, fittings, and valves excluding Manifold Room piping; 2. Thickness test on critical piping in manifold room to determine remaining useful life for discharge piping; 3.

Replace dewatering pumps and piping; 4. Replace lift pumps; 5. Evaluate remaining life for existing VFDs and compatibility with future pump replacement; 6. In conjunction with pump replacement, evaluate ways to mitigate grit issues (i.e., pump type, slurry pump with agitator);

7. Evaluate the need for flushing system, and then determine if assets should be replaced; 8.

Pumps are expected to reach the end of their useful lives around 2030 and will need replacement to maintain system reliability and 9. Perform detailed evaluation on the condition of the existing force main.
10002417 Hudson Ave Pump Station and Outfall Improvements Project Completed. This project involved working with other City departments as necessary to request two affected property owners to install sewer laterals from their properties to the sewer main on Innes Avenue. The project also involved working with other City departments to determine the feasibility and possibility of implementing a loan program or other financial assistance to the property owners for their construction of the lateral connection to the sewer main. After the affected properties have sewer lateral connections to the sewer main in place on Innes Avenue, the Hudson Avenue Pump Station and the 1-block of 8-inch easement sewer will be deactivated by plugging and capping the pipe with light weight concrete.

Coordination with SFPW will be required on sidewalk encroachment issues related to one of the affected properties. External outreach will also be needed to implement the solution, in coordination with SFPUC Communications. The project assumes that the property owners will hire and pay for their own contractor to install necessary pumps or laterals to make a connection to the sewer on Innes Avenue.

25 Appendix A | WWE Quarterly Report | Q2-FY2025-2026 (10/01/25–12/31/25) 10002419 Force Main Rehab at Embarcadero and Jackson Streets This project has been complete. The purpose of the project is to provide redundancy for critical facilities which helps meet the Wastewater Level of Service goal of providing a compliant, reliable, and flexible system that can respond to catastrophic events. This project consists of rehabilitating the remaining 240-feet of NSFM, which is most susceptible to failure, by installing a 28-inch outside diameter HDPE pipe into the existing 36-inch diameter steel force main. In addition, the project will include construction of a new valve vault and associated mechanical and electrical equipment, refurbishment of mechanical and electrical equipment inside an existing valve vault, and installation of a new electrical pedestal and control units aboveground. Together, the mechanical and electrical equipment will allow Wastewater Enterprise Operations operational redundancy to direct combined sewage flows to either the NSFM or to the NSCFM.
10026829 Cesar Chavez Pump Station
Project Completed. Under this project, stormwater and groundwater that collects under the Cesar Chavez freeway underpass within a bounded area will be conveyed to SEP. As this is not an all-weather pump station, WWE determined that this project is a lower priority than other all-weather pump stations. The remaining needs of the project may be added to the WWE R&R program list for consideration. After the NAR and the Draft AAR were completed, it was determined that this project is less critical than other dry-weather or all-weather pump station improvements. Therefore, this project completed the Draft AAR. 10002465 Marin Street Sewer Replacement
This project has been completed. The project will upsize the 24-inch diameter sewer (located between the intersection of 3rd Street and Marin Street and the Marin Street Outfall Structure) and associated sewers to handle the additional dry-weather flows projected from the tributary area. The wet-weather conveyance associated with this sewer system will also be evaluated but any identified scope for addressing wet-weather conveyance issues is not included in this project. Hydraulic studies of the watershed area will be performed to determine the hydraulic adequacy of the pipelines in the area based on expected flows from approved developments, as well as to confirm the necessary pipe size. The existing 24-inch diameter sewer in the vicinity of Marin Street, between Indiana Street and Marin Street CSD (located under southbound Highway 280) will also be upsized. The existing 24-inch diameter sewer on Marin Street, between 3rd street and Indiana Streets, will be replaced with a larger diameter sewer. 10002485 Griffith Pump Station Improvements
This project has been completed. The aging mechanical and electrical systems at Griffith Pump Station is refurbished and its expected service life is extended. The facility is modernized, which reduces energy use and future maintenance requirements. The scope of the project included replacing the dry weather pumps and rebuilding the wet weather pump, installing new sump pumps to maintain the existing capacity of 11.5 MGD and 120 MGD, new bar screens, two new bridge cranes in the manifold room and main pump area, and a new tamper-proof roof access ladder. The bar rack room crane is replaced with a new monorail

The project includes sidewalk and streetscape improvements; median and bicycle lane additions on Masonic Avenue; construction of a small park on the southwest corner of Geary Boulevard and Masonic Avenue; and incorporation of public art elements along this corridor. In conjunction with the SFPW Masonic Avenue Complete Streets Project, the Masonic Avenue Sewer Replacement Project includes rehabilitating/ realigning existing sewers as well as constructing new sewer

27 Appendix A | WWE Quarterly Report | Q2-FY2025-2026 (10/01/25–12/31/25) mains, manholes, side sewers and catch basins. The sewer scope includes approximately 4,700 linear feet of sewers ranging from 12-inch to 24-inch in diameter. 10002138 North Shore to Channel F M Drainage Improvement Project Completed. North Shore Force Main (NSFM) provides critical conveyance of combined sewage and stormwater flows as well as redundancy, which did not exist before this project. Approximately 2,750 LF of the 8,000 LF of this force main is located in The Embarcadero Roadway and was constructed of either steel pipe or ductile iron pipe (both are susceptible to corrosion). After emergency repairs in 2008, a project was initiated under the Wastewater Capital Improvement Program to construct a redundant force main (North Shore to Channel Force Main [NSCFM]), so the 2,750 LF of the existing NSFM may be taken out of service for complete repairs.
10041324 CHFM Inspection and Rehabilitation - Southern Portion The 66-inch diameter Channel Force Main (CHFM) conveys flows from Channel Pump Station (CHS) to the Southeast Water Pollution Control Plant (SEP). Limited evaluations performed on the CHFM have shown sections that are vulnerable to damage from major earthquake and long-term soil settlement. This force main cannot be taken out of service for a significant amount of time for maintenance, as it is always in service and limited shutdown time. This project allows for the internal inspection of approximately 2,600 LF of the southern portion of the force main to SEP, which is assumed to be performed by a multi-sensor remote operated vehicle (ROV). It is assumed that the ROV will be able to collect will include video camera, sonar, and lidar data capture equipment. Once the condition of the facility is evaluated, the design and construction for the required level of rehabilitation will be performed. The assumed rehabilitation budget assumed cured-in-place lining (CIPL) for the southern portion of the CHFM. The project has a positive impact on operations and helps ensure a critical conveyance facility is brought to a good state of repair and helps meet the Operational Reliability LOS.

30 Appendix A | WWE Quarterly Report | Q2-FY2025-2026 (10/01/25–12/31/25) survey of mains relative to property and easement boundaries; 3. Camera inspections of the mains; 4. A localized repair and main realignment; and 5. A high-level conceptual study of potential solutions. The project alternatives can include options such as drainage modifications within private parcels which would require close coordination with City Attorney's Office, Communications, DBI and the homeowners directly. This project covers only the planning activities, including preparation of the Needs Assessment Report (NAR), Alternatives Analysis Report, and Conceptual Engineering Report (CER). Subsequent work will be performed under the Pine Lake Easement Sewer Relocation – Phase B (Design and Construction) project.

CWWLID02 Islais Creek Green Infrastructure
This project will incorporate green stormwater management into an urban design to meet the neighborhood's needs and the stormwater performance goals for the Islais Creek watershed (i.e. manage the first 0.75 inch of rainfall for a 5-year, 3-hour storm event within the drainage management area). The project will also provide secondary benefits by creating new plazas that can serve as neighborhood gathering spaces, greening of the neighborhood by adding more vegetated areas within the right-of-way (ROW), and adding curb bulb-outs to enhance pedestrian and bicyclist safety. Additional work includes construction of bioretention and pervious concrete plazas, construction of permeable pavement parking strips, and developing parking spaces and traffic lane configurations based on recommendations from SFMTA & SF Planning.
10026813 Islais Creek Green Infrastructure (SPLIT)
This project has been completed. This project incorporated green stormwater management into an urban design to meet the neighborhood's needs and the stormwater performance goals for the Islais Creek watershed (i.e. manage the first 0.75 inch of rainfall for a 5-year, 3- hour storm event within the drainage management area). The project also provided secondary benefits by creating new plazas that can serve as neighborhood gathering spaces, greening of the neighborhood by adding more vegetated areas within the right-of-way (ROW), and adding curb bulb-outs to enhance pedestrian and bicyclist safety. Additional work included construction of 12 bioretention planters and a subsurface infiltration gallery. This project is also referred to as the "Mission and Valencia Streets Green Gateway".

CWWLID01 Cesar Chavez Green Infrastructure
The purpose of this streetscape and sewer improvement project, which focused on the segment between Guerrero Street and Hampshire Street, was to improve the safety, aesthetics, and infrastructure and transit efficiency of the corridor. This project also turned Cesar Chavez into a sustainable "green street" by increasing the number of street trees, implementing Low Impact Development (LID) practices, and installing stormwater planters to add green landscaping pockets and provide for stormwater management. The project widened the existing median to allow for many more street trees and landscaping; provided left turn pockets for turning vehicles; widened the sidewalk at the corners; and upgraded the street lighting along the corridor to LED to provide brighter, whiter light and reduce energy consumption. Permeable paving and bioretention were also integrated into the street design.

31 Appendix A | WWE Quarterly Report | Q2-FY2025-2026 (10/01/25–12/31/25) This strategy fuses infrastructure with urban design, allowing the streetscape to become part of the solution to drainage problems. This project has been completed. 10026805 Sunset Green Infrastructure
This project has been completed. The Sunset Boulevard Greenway project constructed a series of tiered bioretention rain gardens in the western stretch of landscaped parcels along 10 to 16 blocks stretching from Golden Gate Park to Lake Merced. The rain gardens manage stormwater runoff on the west side of Sunset Boulevard from the street, paths, and a portion of the landscaped parcel area. The project also incorporated a "Learning Lab" to supplement elementary school curriculum. This project is also referred to as "Sunset Boulevard Greenway."
10026806 North Shore Green Infrastructure
This project has been completed. This project routed stormwater to flow-through bioretention planters with surfaces set lower than the surrounding grade. During large storm events, ponded water at the surface of the planters reaches a maximum depth of 6 inches before it crests an overflow weir, either to a lower planter tier or to a concrete valley gutter running the length of the alley. To protect the adjacent building foundations, an impermeable waterproof liner was placed along the bottom and sides of the planters. New street surfacing and furnishings provide improved community space for local residents and visitors. This project is also referred to as "Chinatown Green Alley".
10026807 Lake Merced Green Infrastructure
This project has been completed. The project starts at the Ashton Avenue intersection and extends along eight blocks to the Lee Avenue intersection. Corner bulb-outs containing bioretention planters were installed on the downstream end of six of the blocks. On the remaining two blocks, roadside bioretention planters adjacent to the curb manage stormwater in lieu of corner bulb-out planters, which were infeasible due to driveway conflicts. The bioretention planters were sized to manage stormwater runoff from the sidewalk and use the minimal area needed in order to minimize the associated parking loss from the new bulb-outs.

Permeable pavement installed within the existing parking lanes on both sides of Holloway Avenue manages runoff from the roadway. This project is also referred to as the "Holloway Green Street".
10026808 Sunnydale Green Infrastructure
This project has been completed. This project included two green nodes in Sunnydale watershed; a mini plaza on Sunnydale Ave. and a rain garden at the eastern end of McLaren Park. These green nodes were designed to maximize the removal of street stormwater runoff from the combined sewer system. At the Sunnydale Avenue Mini-Plaza, bulb-outs containing bioretention planters were installed to remove stormwater while also providing traffic calming and pedestrian safety. At the Leland Avenue Rain Garden, terraced bioretention facilities were created to capture, store, and infiltrate runoff from the impervious roadway and an adjacent vegetated sloped area. Approximately one block of local sewer work on Rutland Street was

32 Appendix A | WWE Quarterly Report | Q2-FY2025-2026 (10/01/25–12/31/25) included into the construction contract to minimize construction impact; however, the project cost of that sewer improvement is accounted for separately. This project is also referred to as the "Visitacion Valley Green Nodes".
10026809 Richmond Green Infrastructure
This project has been completed. Specific work completed at El Camino Del Mar includes providing new pedestrian crosswalks, terraced rain gardens, subsurface infiltration galleries, soil stabilization techniques in selected locations, sewer main upsizing between Lands End Trailhead and manhole east of 32nd Avenue, and Americans with Disabilities Act compliant crosswalks. Specific work completed at Beach Terrace includes permeable pavement, rain garden bulb outs at the eastern & western ends of the permeable pavement, a flow-through rain garden, traditional (infiltrative) rain garden bulb-outs, improved catch basins, and a traditional rain garden. This project is also referred to as the "Baker Beach Green Street". 10026812 Channel Green Infrastructure
This project has been completed. This project is also referred to as the "Wiggle Neighborhood Green Corridor". The purpose of the Wiggle Neighborhood Green Corridor project is to implement low impact stormwater management along the Wiggle bike route between Duboce Street and Fell Street to reduce flooding and provide additional stormwater management benefits to the SSIP. Key features of this project include installation of bulb-outs on selected street corners, bioretention planters, and permeable pavement. 10042088 Citywide Green Infrastructure Implementation (New) Citywide Green Infrastructure Project Implementation funds the conceptual engineering, design, and construction of "implementation ready" green infrastructure (GI) projects within all eight (8) urban watersheds. This project, in conjunction with GI-01, Green Infrastructure Planning, will deliver 65 acres of drainage management area (DMA) managing 35 million gallons of stormwater each year, once complete. Although GI CIP has several candidate projects that will be planned before the start of the FY24/25 WWE CIP, SFPUC anticipates that the candidate project list will change over time to leverage new partnership projects. The $100M budget for this project is based upon an average project cost per acre managed of $1.5M over the 10-year period and GI performance objective of 65 acres. This average project cost is based off prior completed project costs, assuming efficiencies in project delivery and increases due to escalation. For accurate project accounting and controls, green infrastructure projects funded by Green Infrastructure Project Implementation will be listed and managed as separate capital projects in the CIP. The number of projects funded by this line item will vary each year based on partnership opportunities and project readiness. This project holds the total budget for Green Infrastructure Capital Projects, and funds the following project activities:

1. Project Management 2. Conceptual Design 3. Detailed Design 4. Project-based stakeholder outreach 5. Construction Management 6.

In addition to the stormwater performance metrics, the considerations that led to this project being selected as the preferred regional Green Infrastructure (GI) site in Cayuga include: Ideal location relative to surrounding flood risks; Positive synergy with providing a solution to historical flooding in the basement of the high school; Quantity and location of impervious area relative to irrigated open space; Supports level-of-service (LOS) by providing benefits to a disadvantaged community; Synergy with Balboa Park Area Plan by the San Francisco Planning Department. This Project involves regional stormwater collection from San Miguel Child Development Center, Civic Center Secondary School, James Denman Middle School, as well as the Balboa High School campus itself. 10015816 Urban Watershed Assessment and Planning Initiation This project has been completed. Many of the SSIP's proposed projects are focused on improvements to surface drainage and collection system management in San Francisco. The SSIP Urban Watershed Assessment Task evaluated and recommended alternatives that balance the use of grey (for example, pipelines) versus green infrastructure (for example, low impact design) for improvements to watershed surface drainage and collection system management. The SSIP utilized an integrated watershed management approach to investigate the health of the City's watershed and identify potential opportunities for stormwater capture, conveyance, detention and possible reuse to address issues of flooding as wells as combined sewage conveyance and storage. Project implementation required the hydrologic and hydraulic analysis of each of the eight drainage basins and included:
identification of various solutions to each basin's unique set of flooding challenges; evaluation of the social, economic and environmental values of alternatives that meet the level of service with a triple bottom line tool and the optimization and prioritization of projects for each basin.

The work addressed life cycle costs and detailed operation and maintenance requirements. 10015817 Urban Watershed Assessment and Planning
The UWA is the comprehensive watershed-based planning process developed to diagnose challenges and design solutions for the surface drainage and collection/conveyance portion of the City's sewer system. The UWA emphasizes holistic urban watershed-scale planning and the development of multiple-function solutions to sewer system challenges. These solutions are evaluated using a comprehensive Triple Bottom Line (TBL) tool that employs societal and environmental benefits and costs with the goal of delivering more holistic investment decisions. Project implementation will require the hydrologic and hydraulic analysis of each of the eight drainage basins and will include identification of various solutions to each basin's unique set of flooding and other challenges; evaluation of the social, economic and environmental values of alternatives using the TBL tool; optimization and prioritization of projects for each basin; and life cycle costs with detailed operation and maintenance requirements.

10029728 Advanced Rainfall Prediction - Part 1
This project includes planning, design, and environmental review for three new radar equipment stations to collect additional data. Although the installation of all three radar equipment stations is not proposed at this time, there is a regional project with other Bay Area agencies moving forward under a grant from the State. Needed coordination and site activities are accounted for in the project. Once all equipment stations are installed and running, the data will be provided in real-time to a new Advanced Quantitative Precipitation Information (AQPI) system, which would perform rainfall prediction modeling for short-term and long term precipitation forecasts, and deliver the resulting forecast to SFPUC automatically in real-time.

The AQPI system is expected to be delivered to SFPUC as a turnkey system, providing SFPUC operations staff with important tools to help inform their decisions. 10029729 Operational Decision System Phase 1
Project Completed. SFPUC desires a more consistent and transparent basis for making decisions that make best use of available data in an automated way. This project integrates available data in the collection system (levels, flows, pump status, etc.) with rainfall prediction data (from National Oceanic and Atmospheric Administration, or in the future improved through the Advanced Rainfall Prediction project). The real-time data will be coupled with WWE's collection system hydraulic model to project the likely impact of approaching storms and generate specific operational recommendations for managing flows. 10026811 17th and Folsom Wet Weather Storage
This project has been completed. The neighborhood surrounding 17th Street, 18th Street and Folsom Street has been experiencing flooding with over a foot of water on the streets, sidewalks and into their houses during rain events, resulting in property damages to the residents. The 17th and Folsom Wet Weather Storage project was originally intended to provide interim flood mitigation to the neighborhood while SSIP is working on identifying long- term solutions through capital improvement projects. The proposed interim flood mitigation alternatives consisted of a storage basin, pump station, and collection facilities to be built underneath the proposed future 17th & Folsom Park. However, the project was cancelled and defunded except for residual funds for ongoing response activities as directed by SFPUC management, including certain outreach activities related to flooding. 10026814 Flood Resilience Analysis (Planning Phase Only) This project has been completed. The Flood Resilience Analysis Project will focus on developing a framework for identifying multiple storm scenarios; quantifying risks and cost implications associated with mitigating flooding across the various storm scenarios; and defining the extent and scope of the City's responsibility, based on consequences of extreme

36 Appendix A | WWE Quarterly Report | Q2-FY2025-2026 (10/01/25–12/31/25) storms. To minimize flood risks citywide and meet SFPUC objectives, this project will also develop programs and policies beyond what the collection system can manage, and make recommendations on prioritization of structural, non-structural, and operational measures. 10026815 Flood Resilience - Early Projects (Planning Phase Only) This project has been completed. The City of San Francisco has experienced multiple significant storms in the last decade, which have led to flooding in various parts of the City.

While Flood Resilience Analysis is being conducted by SFPUC, early infrastructure projects are being planned at three critical areas (Cayuga, Wawona, and Folsom neighborhoods) subjected to high flood risk. This project focuses on planning and developing stormwater detention and conveyance concepts specific to each of the aforementioned critical neighborhoods.
10026817 Cayuga Ave Stormwater Detention Project
This project has been completed. The neighborhood surrounding the northeastern end of Cayuga Avenue has been susceptible to recurring flooding associated with moderate to heavy storms. Due to its low land topography, the area can experience up to a few feet of water on the streets and sidewalks during rain events. This project improved the stormwater detention by re-grading the I-280 embankment at the foot of Cayuga to create a low lying detention field.

This project provided surface detention of flows during flooding and included an overflow relief connection into the College Hill Tunnel as well and a retaining wall to support the roadway. 10026819 17th and Folsom Permanent Barriers
This project has been completed. SFPUC has purchased off-the-shelf plastic temporary flood barriers for 2015 and 2016 wet seasons. At locations where temporary plastic flood barriers were installed and proven effective in mitigating floods, SFPUC installed more durable custom aluminum or steel barriers before a permanent solution (Folsom Area Stormwater Improvement Project) can be implemented. The aluminum or steel barriers were installed during wet seasons and removed during dry seasons. The sidewalk was graded and outfitted with recessed and covered receptacles for mounting flood barrier poles. Interlocking aluminum logs were installed between the poles. The flood barrier system was custom built based on site-specific pole intervals, barrier height, and other characteristics. 10026820 Hydraulic and Drainage Sewer Improvements
This project includes awarding "As-Needed Construction Contracts" to implement small and non- specialty sewer improvement projects at critical flood prone neighborhoods. Examples of non- specialty, small infrastructure construction include improvement of drainage features, upsizing/expansion of sewer pipes, and surface grading modifications. Three preliminary projects (areas) were identified: Joost/Foerster Sewer Expansion, Urbano/Victoria Drainage Project, and Wawona Interim Drainage Project. Additional projects will be added as the needs arise.

37 Appendix A | WWE Quarterly Report | Q2-FY2025-2026 (10/01/25–12/31/25) 10040621 Floodwater Management Grant Assistance Program (Grant) The primary goal of the Grant Program is to encourage the implementation of site-specific floodproofing measures by providing grants to property owners to implement projects that improve flood resilience of their property. While the existing Grant Program has made multiple improvements to expand project types, increase funding caps, reduce financial burden, and improve the reimbursement structure, this project includes the development and implementation of further enhancements and expansion of the program. The Grant Program project scope includes: 1. Grant funds to be disbursed to property owners for the design and construction cost of approved floodproofing projects to improve flood resilience of property. 2.

Program development and administration support. 3. Program technical support to perform project eligibility and feasibility assessments. 4. Support for outreach to property owners. 10029733 Land Reuse of 1800 Jerrold Avenue
This project includes the acquisition of this site for possible near-term and long-term SFPUC use. This 6.04-acre site on Jerrold Avenue between Quint and Rankin, is adjacent to the Southeast Plant and is currently occupied by another city department, Fleet Management under the Office of Contract Administration. The site is used as a central shop for vehicle repairs. Acquisition of the site by the SFPUC would be beneficial because there are very few empty or underutilized sites around the SEP; and, after completion of any necessary planning and environmental review, this site can serve a variety of functions to support the SEP's short and long-term efforts.
10026824 SEP Oxygen Generation Plant
The Oxygen Generation Plant (SE01) involved installation of two packaged vacuum pressure swing absorption (V/PSA) oxygen generation systems to provide gaseous oxygen (GOX) supply.
10015808 SEP Existing Digester Roof Repairs
This project has been completed. As part of the SSIP, a new biosolids handling facility was built to replace the existing system. The existing digesters and associated facilities must continue to handle all biosolids generated by primary and secondary treatment operations at SEP until all planning, design, construction, and commissioning activities for new facilities are complete. This project maintains existing digestion facilities in operation with sufficient capacity and reliability to produce Class B biosolids until new facilities are available for service. The project consisted of repairs to the existing floating roof and associated appurtenances (Digester 8), and replacement of the existing floating roofs and associated appurtenances (Digesters 4, 6, 7 and Cake Bins 3 & 4).
10026825 SEP Primary and Secondary Clarifier Upgrades

Covers for the primary sedimentation tanks and ventilation system were also installed. Similarly, major upgrades for the secondary clarifiers included replacing key equipment and retrofitting existing secondary clarifiers (8 of 16 included in this project). Structural repairs were addressed including concrete crack repairs and coating.
10002192 SEP 521/522 and Disinfection Upgrades (SEP Building Replacement) This project has been completed. This project included upgrades to the Post-Chlorination Building as well as construction of a new building to house electrical and hydraulic controls, and replacement of valves and actuators in the Chlorine Contact Channel and stop logs at the Effluent Control Structure. The new building for electrical and hydraulic controls were constructed to meet the Sewer System Improvement Program (SSIP) seismic reliability goals.

In addition, this project will upgrade and relocate the non-potable (W3) pump system by replacing four existing W3 pumps and motors with six new higher flow capacity pumps. 10002220 SEP Primary Sludge Handling Improvements
The project was considered complete at the end of the design phase. The project's scope of work included a new building to house primary sludge screens; grit removal equipment; grit washing and clarification equipment; ancillary equipment including pumps; a new Gravity Belt Thickener (GBT); rehabilitation of the existing two GBT units; replacement of existing odor control equipment; and upgrades to existing exhaust fans. However, after design was completed, it was determined that this project is less critical than other long-term treatment improvements. Therefore, this project completed the closeout of design. Rehabilitation of critical components was deferred to the WWE R&R program for consideration. 10026826 SEP Existing Digester Gas Handling Improvements This project has been completed. As part of the Sewer System Improvement Program (SSIP), a new biosolids handling facility will be built to replace the existing system. However, the existing digesters and associated facilities must continue to handle all biosolids generated by primary and secondary treatment operations at Southeast Plant (SEP) until all planning, design, construction, and commissioning activities for new facilities are completed. The project consists of process upgrades addressing deficiencies related to digester gas compressors, heat exchangers and controllers, combined primary activated sludge (CPAS) tank, boiler and boiler stacks, waste flare and cogeneration cooling water system, and B100 biofuel tank (EPA permit compliance). Building systems and odor control unit (OCU) upgrades such as replacing roof drains, OCUs and upgrading ventilation and OCUs, roof replacement, and air compressor (BAAQMD Permit Application) will also be completed.
10015553 Biofuel Alternative Energy
The Biofuel/Alternative Energy Program will determine if it is feasible and cost-effective for the SFPUC to generate bioenergy (e.g., Biofuel or cogenerated power) as a byproduct of processing the fats, oils, and grease (FOG) and/or food waste collected throughout the city.

39 Appendix A | WWE Quarterly Report | Q2-FY2025-2026 (10/01/25–12/31/25) Feasibility will be determined through pilot studies and analysis that will evaluate whether adoption of Biofuel energy programs into the SFPUC's wastewater infrastructure (collection systems and/or treatment processes) would reliably and cost effectively enhance performance and sustainability.
10015811 SEP Oxygen Generation Plant 01
This project has been completed. The existing liquid oxygen (LOX) facility at Southeast Plant (SEP) does not meet current safety codes and needs replacement. The LOX system is a mandatory redundant system to the on-site oxygen generation to ensure full compliance with the NPDES permit. This project includes the demolition of the LOX facility (three horizontal LOX storage tanks, four vaporization systems, and ancillary equipment); demolition of SEP 270 Oxygen Generation Building; installation of structural piles; construction of concrete slabs and utility trench; and installation of a new packaged LOX system consisting of four vertical LOX storage tanks, vaporizers and an unloading station. 10041824 SEP Mainstream Nutrient Reduction
The purpose of this project is to reduce the amount of nutrients, specifically total inorganic nitrogen, discharged from SEP into San Francisco Bay. Based on a preliminary conceptual evaluation, the proposed project assumes maximization of the use of existing infrastructure in an effort to reduce costs. The proposed project assumes a scope of work that includes: the retrofit of the existing high purity oxygen activated sludge system to produce densified activated sludge; the construction of a new biological nutrient removal (BNR) system; modification of existing aeration basins (Facility 200); replacing the pure oxygen system; and other major components, such as a new blower building, distribution channels and pipe connections for the primary effluent, secondary liquid stream (mixed liquor) and return solids, and supporting appurtenances and utilities. The proposed project includes planning, environmental review, design, construction contract procurement, construction and closeout phases of the project.
10029738 Westside Pump Station Redundant Force Main Improvements Flow from the Westside Pump Station (WSS) is transported through an existing force main with no reliable redundancy. The purpose of this project is to ensure operational flexibility and reliability of critical force main infrastructure functions. This is accomplished by providing a redundant force main pipeline and supporting valving sized to maximum treatment plant capacity. This project includes planning, design, environmental review and construction of a redundant new force main from the WSS to the OSP. Major components of this project include installation of 6,400 linear feet of new force main on Sloat Blvd and Highway 35, as well as street pavement demolition and restoration, traffic control, and relocation of impacted utilities.

During the planning phase of this project, staff determined that this project may be deferred with accepted risks to SSIP Phase 2.

40 Appendix A | WWE Quarterly Report | Q2-FY2025-2026 (10/01/25–12/31/25) 10039184 Westside FM Reliability Project - PLANNING
For the redundant force main, the proposed alignment from AAR is Alternative 1, which is approximately 2,765 total linear feet and requires a short overall pipeline length. This alignment mainly runs west from the connection point then south and parallel: either west of the existing force main within the paved outer northbound lane in the Great Highway or east of the existing force main within the east shoulder of the Great Highway, then turns east to connect to the headworks at OSP 011. This project will advance the existing AAR through CER, and in the process, also consider risk mitigation strategies with continuing operation of the existing Westside Force Main. Details of the CER will form the basis for Project OSP-1B:

Westside Force Main Reliability Project – Design and Construction. 10029735 OSP Fine Screen and Grit Removal Enhancements
This project has been completed. The purpose of this project is to maximize solids/grit removal efficiencies at the plant headworks thereby reducing grit throughout the wastewater treatment facility processes; minimize potential grit impacts to biosolids processes and reduce O&M costs associated with grit wear on treatment process equipment. The project includes planning, design and environmental review of the following major components: controls improvements of the three existing 1/4-inch fine screens; evaluation/upgrade of the three existing Pista-type grit removal units with higher efficiency new fine grit removal units such as the hydraulically-induced vortex-type (Headcell) or other high-efficiency technologies that remove fine grit, and structural modifications to the influent channels / headworks structure to suite new grit removal units. The construction phase of this project is proposed in SSIP Phase

2. However, the SSIP re-prioritization in 2016 has resulted in the deferral of remaining efforts in planning, design and environmental review to Phase 2. 10029739 OSP Condition Assessment Repairs
This project has been completed. The Ocean Side Plant (OSP) Condition Assessment Repairs project will include major improvements to the plant, aimed to address the reliability of existing assets that have deteriorated over the years.

Improvements focus on maintaining operational reliability and extending the service life of buildings that are required to remain in operation for 30 years or more.
10029740 OSP Odor Control Optimization
This project has been completed. Although the odor control facilities at OSP have been effective at collecting and treating odors generated in various locations throughout the facility, the efficacy evaluation of the process identified inherent inefficiencies that can result in opportunities for significant O&M cost reduction. Currently, the air from the entire building is exchanged and scrubbed for odor. In order to significantly reduce the volume of air treated for

41 Appendix A | WWE Quarterly Report | Q2-FY2025-2026 (10/01/25–12/31/25) odor, the primary clarifiers may be covered and only air from the primary clarifier basins would be scrubbed. The main components of this project include planning, design, environmental review and construction/upgrades of new covers for the five primary clarifiers and duct work to connect the head space in each clarifier basin to the odor control system. Current plans involve the completion of an odor control study as part of the Alternative Analysis Report (AAR) planning phase. Depending on the results of the alternative analysis, the project might forego covering the primary clarifiers and/or implement other optimization measures in its place.
10039185 OSP Odor Control Upgrades

The purpose of this project is to ultimately reduce the amount of nutrients, specifically total inorganic nitrogen in the treated effluent from the Southeast Wastewater Treatment Plant

45 Appendix A | WWE Quarterly Report | Q2-FY2025-2026 (10/01/25–12/31/25) (SEP) being discharged into the San Francisco Bay. This project represents a near term action to reduce nutrients in the effluent by reducing the ammonia load that is recycled back into the treatment plant as a sidestream. A separate, long-term project is being included for full scale nitrogen reduction at the SEP. This sidestream project will provide biological treatment processes and supporting appurtenances to decrease the nitrogen levels in the centrate wastestream generated from the existing centrifuge dewatering facility (Facility 840).

This interim facility will also be able to accommodate a portion of the filtrate from the new dewatering facility (Facility 615) under construction in the Biosolids Digester Facilities Project, once it is in service. Major project components include de-ammonification reactors in the existing abandoned Dissolved Air Thickeners (DAF) tanks located at the southside of SEP (south of Jerrold Avenue) and the installation of a filtrate pipeline from Facility 615 to the de- ammonification reactors. The target is to have this interim side stream treatment facility in operation by early 2026.
10038793 Customer Service System
This project will transform the Customer Service experience at the SFPUC. It will modernize our technology and enable us to optimize business processes to align with current and future Customer Service needs and bring increased operational effectiveness. The project has 3 main components - a) Migrating to a modern, flexible cloud-based contact center solution, b) Migrating from our legacy "My Account" platform to a new digital self-service and customer engagement platform, and c) Migrating from our on-premises legacy Customer Information System (CIS) CC&B (Oracle "Customer Care & Billing") to Oracle's replacement CIS solution - Oracle CCS ("Customer Cloud Service"). These are all significant changes across our Customer Service and IT infrastructure.

TBD-08 SEP South Jerrold Avenue Campus (Planning and Environmental Review) This proposed project includes preparation of the Environmental Impact Report (EIR) for the SEP Campus Plan – South Campus, in conformance with the provisions of the California Environmental Quality Act (CEQA), the CEQA Guidelines (California Public Resources Code Section 15000 et seq., "CEQA Guidelines"), and Chapter 31 of the San Francisco Administrative Code. CEQA requires the preparation of an EIR when a project could have significant unavoidable impacts on the physical environment. The physical boundary of the South Campus is Jerrold Avenue and Oakdale Avenue, and Phelps Street and the Caltrains line.

46 Appendix A | WWE Quarterly Report | Q2-FY2025-2026 (10/01/25–12/31/25) 15722-SD R&R Collection Systems - Small Diameter
The purpose of the Wastewater Enterprise (WWE) Renewal and Replacement Program (R&R) Collection System Small Diameter Sewer project is to maintain the existing functionality of the sewage collection system and address planned and emergency projects for repair and replacement of structurally inadequate sewers. This project consists of the following sub- projects: small diameter (less than and equal to 36-inch) sewer improvements, small diameter (less than and equal to 36-inch) sewer condition assessment, spot sewer replacement. By utilizing an asset management approach, which factors in: physical condition, age, location, risk, public safety, paving schedule and other factors, aging and failed portions of the collection system are identified and replaced.
15722-LD R&R Collection Systems - Large Diameter
The purpose of the Wastewater Enterprise (WWE) Renewal and Replacement Program (R&R) Collection System Large Diameter Sewer project is to maintain the existing functionality of the sewage collection system and address planned and emergency projects for repair and replacement of structurally inadequate sewers. This project consists of the following sub- projects: large diameter (greater than 36-inch) sewer cleaning and condition assessment, and large diameter (greater than 36-inch) sewer improvements. By utilizing an asset management approach, which factors in: physical condition, age, location, risk, public safety, paving schedule and other factors, aging and failed portions of the collection system are identified and replaced.
15724 R&R Treatment Facilities
The purpose of the Wastewater Enterprise (WWE) Repair and Replacement (R&R) Program Treatment Plant Improvement projects is to maintain the capacity and reliable performance of the wastewater treatment facilities owned/operated by the Wastewater Enterprise. This is a continuing annual program to extend the useful life of the WWE treatment assets. Treatment Facility Wastewater Enterprise Assets include: Transport Boxes, Discharge Structures, Pump Stations, Force Mains, Tunnels and Treatment Plants. The R&R Treatment Facilities projects are prioritized based upon regulatory compliance, condition assessments, Operation staff recommendations and Level Of Service goals. Planned WWE R&R Program Treatment Plant Improvement projects will address aging infrastructure at the wastewater enterprise treatment facility assets. Planned WWE R&R Program Treatment Plant Improvement projects are prioritized based on risk to permit compliance, safety and urgency. The failure of any major component of the wastewater treatment facilities could be catastrophic, compromising the SFPUC's ability to handle and treat wastewater, which could result in severe public health, safety, regulatory, and environmental impacts.
15722-TS T/S Box Tier 2 (Field) Condition Assessment
The Tier 2 condition assessments in this project are intended to follow the previously performed Tier 1 condition assessments. The specific assets to be inspected, as well as their priorities, will be identified based on the Tier 1 information and other considerations. Tasks that would be performed as part of the inspection include information collection and review,

47 Appendix A | WWE Quarterly Report | Q2-FY2025-2026 (10/01/25–12/31/25) field inspection including selection of inspection technique, logistical planning, and coordination; Execution of field inspection work; Review and analysis of inspection results, assessment of condition, development of recommendations and preparation of condition assessment reports. Due to the wide range in the sizes of the boxes, physical configuration and operational conditions, variability in approach is anticipated for each specific asset. Upon selection and prioritization of the T/S boxes to be inspected, asset-specific methodologies and budgets will be developed. Based on the size of the boxes, a limited number, if any, may be inspected using robotic multi-sensor equipment due to technological limitations such as lighting and video quality. Person entry may be required. Logistical components such as access, safety and flow bypass may be identified during the planning phase. If existing access points are not suitable to support inspection (person entry or robotic), improvements to or creation of access points may be required. Based on an assumed cost of $1,000,000 per mile, the budget for this project may address inspection of up to 10 miles of T/S boxes.

DEFINITIONS
Baseline (CIP Baseline / Approved Baseline): A formally approved reference point for a project’s scope, schedule and budget that is used to measure and control performance throughout the life of the project.

Baseline Scope/ Approved Scope: The scope and list of deliverables included in the baseline and it is approved by the SFPUC Commissioner (as outlined on the Project datasheets submitted within the 10-Year CIP).

Baseline Schedule/ Approved schedule: The approved timeline (start and finish dates) as developed in the project baseline.

Baseline Cost/ Approved Budget: The approved budget or cost to complete a project as developed in the project baseline.

Beneficial Reuse: The use of a facility, system, or portion of a project for its intended purpose before full project completion, when it is safe and functional. It allows the owner to gain operational value while remaining work continues.

Commissioning: A systematic process for verifying and documenting that the systems, equipment, or infrastructure are installed, tested and performing according to design intent, operational requirement, and the owner standards.

Escalation: The increase in construction cost over time due to factors such as inflation, labor and material increase, and market conditions.

Punch List: A list of incomplete, defective, and nonconforming items identified near the end of a construction project that must be corrected or completed before final completion of construction contract, acceptance, and closeout.

Start-up / Startup: The initial phase of placing equipment or systems into operation, including testing, calibration, adjustments, and operator training, to ensure systems function properly prior to full commissioning and acceptance.
