San Francisco Public Utilities Commission Wastewater Enterprise Budget and Capital Plan Public Hearing

This meeting focused on the presentation and discussion of the Wastewater Enterprise's operating and capital budgets for fiscal years 2027-2028, featuring comprehensive reviews of major infrastructure investments, regulatory compliance initiatives, and rate affordability considerations.

Meeting Overview

The commission convened to review the Wastewater Enterprise's proposed budgets totaling approximately $5.9 billion over 10 years in capital investments, alongside significant operating budget increases driven primarily by debt service obligations. Assistant General Manager Joel Prather presented detailed plans for maintaining San Francisco's combined sewer system while balancing ratepayer affordability with regulatory compliance and infrastructure reliability needs.

Opening and Land Acknowledgment

President Arce opened the meeting with a land acknowledgment recognizing the Muwekma Ohlone tribe as the original inhabitants and stewards of the lands where the SFPUC operates. The commission acknowledged the ongoing partnership with the Muwekma Ohlone people and their continued presence in Bay Area communities.

Wastewater Enterprise Operating Budget (Item 3A-I)

Enterprise Overview and Mission

AGM Prather outlined the Wastewater Enterprise's core mission to protect public health and water quality in the Bay and Ocean. The enterprise operates:

  • San Francisco's only combined sewer system on the California coast (one of three on the West Coast alongside Portland and Seattle, and one of over 700 nationwide)
  • Three wet weather treatment plants and one wet weather treatment facility
  • 36 pump stations (increased by four in the past year due to Treasure Island asset transfers)
  • Eight transport and storage facilities with 200 million gallons capacity
  • Over 240 green infrastructure installations
  • 25,000 catch basins connected to 1,000 miles of pipes
  • Treatment capacity of approximately 34.6 billion gallons of wastewater annually
  • Over 500 staff positions across eight divisions

Major Operating Budget Changes

The operating budget presentation highlighted several significant cost drivers:

Debt Service Increase: $139 million increase representing the largest year-over-year cost driver for the entire PUC budget. Deputy CFO Laura Bush explained this increase results from bonds issued for major capital projects (including SSIP projects at Southeast Plant) that are now coming due. The PUC typically capitalizes interest for two years after bond issuance, and these obligations are now becoming active.

New Staff Positions: Five temporary-to-permanent position conversions (no net new positions added):

  • 1824 Capital Lead (Admin)
  • 0923 Training Workforce Manager (Admin)
  • 1840 Management Assistant (Admin)
  • Two 5620 Regulatory Specialists (Regulatory Compliance Division)

These conversions are effectively budget-neutral as the temporary positions were already funded, with costs offset through attrition savings adjustments.

BDFP Project Support Costs:

  • $1.8 million one-time purchase for furnishings and non-process equipment (desks, chairs, laboratory equipment, forklifts, shuttle lifts)
  • $2.6 million annual increase (starting FY28) for additional 2.6 megawatts of power needs
  • $1.5 million annual increase (starting FY28) for expanded chemical requirements
  • Costs absorbed in FY27 during testing and startup phases

Biogas Utilization Facility: $1.35 million annual increase (starting FY28) for additional 1.6 megawatts of power, plus $1 million annual O&M service contract for five years to operate the new biogas scrubbing system.

Other Operating Costs:

  • $1.3 million for cost of living increases
  • $4 million for new power requirements
  • $2 million for furnishings
  • $2 million for new laboratory equipment at Southeast Plant for regulatory compliance
  • $500,000 ongoing funding for Southeast Community Center events and programming (eliminating reliance on add-back funding)
  • $712,000 annually for Foxborough DCS (Distributed Control System) maintenance support contract

Division Structure

AGM Prather introduced division managers who stood for recognition:

  • Operations (Angela Chung): Operates treatment and pumping facilities
  • Maintenance (Michael Maravilla, absent): Maintains pumping and treatment facility assets
  • Engineering (Joe Wong): Supports all divisions and construction projects
  • Collections (Linda Candelaria): Manages gravity sewers and pre-treatment/industrial users programs
  • Business Strategy and Performance (Elaine Leeming): Handles HR, budget, and admin functions (Matt Brown recognized for budget work)
  • Enterprise Capital Planning (George Engel, absent; represented by Emma Mack): Infrastructure planning and capital project coordination
  • Urban Watershed Planning (Sarah Minnick): Green infrastructure and development areas
  • Regulatory Compliance (Amy Chastain): State and federal regulatory interactions and reporting

Enterprise Goals and Performance

AGM Prather highlighted key enterprise achievements:

  • Meeting all regulatory requirements with plans for future compliance
  • Strengthening employee core competencies (recent employee survey achieved new high marks for participation and favorability)
  • Minimizing asset failures and maximizing runtime for uninterrupted 24/7 service
  • Fiscally responsible resource management

Wastewater Enterprise Capital Budget (Item 3B-I)

Capital Plan Overview and Prioritization

The 10-year capital plan totals $5.9 billion, down from $7.4 billion proposed in September 2024—a 20% reduction ($1.5 billion in deferrals) achieved through rigorous prioritization balancing ratepayer affordability with service reliability and regulatory requirements.

Prioritization Framework: Projects evaluated based on:

  • Regulatory compliance
  • Health and safety
  • Environmental risk
  • Operational reliability and risk of failure
  • Stormwater management and climate resilience
  • Systematic vulnerabilities

Key Context: San Francisco has the second-highest construction costs in the world (after New York City, ahead of Zurich, Switzerland), significantly impacting capital project expenses.

Major Capital Projects

1. Southeast Plant (SEP) Nutrient Reduction Project

Total Budget: $1.47 billion (appropriations FY27-36: $1.42 billion; project extends beyond 10 years)

Purpose: Reduce nutrient levels in Southeast Plant effluent to improve Bay water quality and prevent algal blooms (like the severe 2022 summer bloom that spread across the Bay causing dead fish and unsightly conditions).

Project Approach:

  • Progressive design-build contract for early contractor involvement
  • Improves constructability, phasing, and allows scope refinement
  • Reduces risk of costly redesigns and change orders
  • Maintains complete plant operability throughout construction (similar to Headworks project)
  • Meets/exceeds city local hiring and local business requirements

Timeline: Commission to review project approval next week as first step in progressive design-build process. Water Board permit requirements drive this compliance project.

Note: Project is independent of Southeast Outfall project; nutrient reduction requirements apply regardless of outfall location.

2. Cleanup and Abatement Order (CAO) Projects

Projects: Lower Alamany and Folsom Street improvements

Purpose: Meet San Francisco Regional Water Quality Control Board cleanup and abatement order; provide sewer improvements, flooding mitigation, additional stormwater storage and conveyance.

Components:

  • Lower Alamany Project: New sewer tunnel and improvements (currently at bid, award anticipated shortly)
  • Folsom Project: New sewer tunnel, enlarged sewer box, and improvements (underway with various stages of planning, approval, and construction)
  • Wawona Sewer Upgrade: Completed in 2024 (third CAO project); no flooding experienced in subsequent winters, demonstrating project success

3. Channel Street Force Main Reliability

Purpose: Ensure reliability of critical asset transporting 100% of sewage and stormwater from northeast San Francisco to Southeast Plant.

Age: Over 50 years old

Approach:

  • Inspection and condition assessment
  • Rehabilitation projects
  • Redundancy/alternative conveyance options
  • Channel Street Intertie Project (in progress): Diverts dry weather flows from Cesar Chavez Street to Southeast Plant, providing redundancy for southern portion and enabling inspection
  • Northern section similar effort planned

4. West Side Force Main Reliability

Purpose: Ensure reliability of asset transporting 100% of influent from West Side Pump Station to Oceanside Treatment Plant.

Age: Over 30 years old

Status: Currently in planning phase with condition assessment underway

5. Southeast Outfall and Booster Pump Station Replacement

Total Budget: $1.98 billion (appropriations FY27-36: $154 million)

Age: Original infrastructure built in 1967 (over 70 years old for some components)

Timeline: Construction intentionally scheduled beyond 10-year window to avoid overlap with other major projects (particularly nutrient reduction) and minimize ratepayer impact.

Current Activities:

  • Planning phase initiated
  • Interim condition assessment and rehabilitation of existing infrastructure
  • Coordination with Port of San Francisco waterfront sea level rise efforts and Army Corps engagement
  • Project location at Islais Creek edge makes coordination with waterfront projects critical

Future Capacity: Will increase booster station capacity to discharge 100% of Southeast Plant effluent to deep water outfall offshore.

6. Ocean Beach Climate Adaptation Project

Purpose: Comprehensive shoreline protection addressing erosion threatening critical wastewater assets including:

  • Lake Merced Transport and Storage Facility
  • West Side Pump Station and force main
  • Oceanside Treatment Plant

Partners: California Coastal Commission, Recreation and Parks, SF Zoo, SFMTA, federal partners

Components:

  • Buried seawall for asset protection
  • Beach access trail
  • Rerouting Great Highway traffic to Slope Boulevard and Skyline (away from narrow coastal section)
  • Beach sand replenishment for improved beach health

Compliance: Part of California Coastal Commission requirements; multi-benefit project.

7. Oceanside Plant-wide Facility Capacity Improvements

Purpose: Consolidate multiple interrelated improvements into coordinated effort addressing:

  • Seismic reliability
  • Primary and secondary treatment
  • Solids handling and odor control

Objectives:

  • Build capacity to meet current demands
  • Accommodate potential future increased flows to Oceanside Plant
  • Prepare for proposed tens of thousands of new residential units on San Francisco's west side
  • Build redundancy and reliability into current processes
  • Plan for future improvements as needed

Rationale: Advance planning necessary as treatment capacity cannot be quickly adjusted; requires years-long lead time.

8. Biosolids Digester Facilities Project (BDFP)

Total Budget: $2.84 billion (70% complete)

Status: Construction over 70% complete; process equipment, piping, mechanical, electrical, and plumbing installed; biogas utilization facility construction begun.

Timeline:

  • Commissioning and testing equipment begins 2025
  • Full testing and operational startup early 2027
  • Final budget presentation (potentially last appearance in budget cycle)

Benefits:

  • Upgrades Southeast Treatment Plant's largest solids processing system
  • Enhances facility capacity and sustainability
  • Produces Class A biosolids (applicable to all crops including human consumption, vs. current Class B applicable only to non-human consumption crops)
  • Meets more stringent regulatory compliance measures
  • Replaces digesters designed in 1940s, built in 1950s

9. Repair and Replacement (R&R) Programs

Scope: 1,000 miles of sewer mains requiring continuous investment

Activities:

  • Inspection and cleaning
  • Rehabilitation
  • Replacement
  • Alternative construction methods (no-dig linings and other procedures)
  • Treatment facilities and pump station R&R for projects larger than in-house maintenance capacity but smaller than full bid projects

Goal: Enable quicker project activation for urgent repair needs.

Major Project Deferrals

AGM Prather emphasized deferrals are not deletions—all projects remain necessary for long-term system sustainability:

1. Southeast Treatment Plant South Campus

Reason: High-level planning for post-BDFP campus repurposing requires more integrated affordability analysis before formal capital plan development.

Status: Proceeding with small investment in environmental planning to inform future decisions for 1950s-era digester facility area.

2. Judah Twin Sewer Project

Reason: Tied to SFMTA rail work on Judah Street; MTA lacks committed start date.

Status: Deferred pending MTA project timeline clarity.

3. Pump Station and Force Main Condition Assessments

Reason: Previous planning based on 2014 data; significant maintenance and R&R work completed since then necessitates data refresh.

Status: Conducting new condition assessments for pump stations and majority of force mains to inform future project decisions (may result in R&R, in-house maintenance, or future capital projects).

Revenue vs. Debt Funding

Financial Planning Director Aaron Corvinova explained the balance between revenue-funded capital and debt-funded capital:

  • Some projects legally must be revenue-funded
  • Long-term projects with longer lifecycles better suited for bond funding
  • Balancing considers affordability, rate increases, and financial policies including capital financing policy mandates
  • Agency-wide slight increase in revenue funding overall
  • Wastewater's large capital investments moved up in planning cycle required increased debt funding in 10-year period due to earlier spending needs
  • Approximately 75% of 10-year CIP will be debt-funded

Financial Policy Compliance

Deputy CFO Laura Bush confirmed:

  • $139 million debt service increase anticipated and planned for years in advance
  • Multiple financial policies guide sustainable financial management
  • Debt service coverage (funds available to pay debt obligations) remains healthy throughout 10-year projection
  • Conservative assumptions include 6% interest rate on future revenue bonds (typically come in lower, producing savings)
  • Savings from refinancing or lower interest costs may apply to ratepayer relief or additional projects depending on future decisions

Commissioner Questions and Discussion

Operating Budget Questions

Commissioner Stacy inquired about "attrition savings" shown in budget proposals. Budget Director Anna Dooning explained this technical budgetary term represents natural savings from attrition/turnover, modified to offset costs of temporary-to-permanent position conversions. The approach is budget-neutral as temporary positions were already funded. Stacy noted concern that attrition savings could disappear if vacant positions are filled; finance staff confirmed continuous quarterly analysis and right-sizing to ensure adequate budget for filling vacancies.

Commissioner Thurlow asked about declining revenue-funded capital trends. Financial Planning Director Corvinova explained revenue and debt funding are balanced independently based on project appropriateness, affordability, rate impacts, and financial policies. Wastewater's increased debt funding reflects large capital investments moved earlier in planning cycle.

Vice President Leveroni sought clarification on $139 million debt service increase. Deputy CFO Bush explained this represents the largest PUC budget cost driver year-over-year, resulting from bonds issued for completed or near-complete projects (primarily SSIP) with two-year capitalized interest periods now expiring. Leveroni confirmed comfort level with impact on bond ratings; Bush affirmed no surprises, with financial policies ensuring sustainable management and healthy debt service coverage throughout 10-year projections. Discussion of potential refinancing savings and whether they'd reduce debt or fund projects; staff noted savings could support ratepayer relief or additional projects depending on future commission decisions.

Capital Budget Questions

Commissioner Stacy appreciated deferral examples and noted affordability limits drive stringent budget processes. She questioned:

  • Program Management costs (bar chart): Confirmed as balance of city staff (PUC, Public Works) and consultants providing needed expertise
  • Nutrient Reduction year-four cost decline: AGM Prather and AGM Robinson explained progressive design-build front-loads planning/contractor engagement, with potential lull as contractor designs before construction ramps up
  • Nutrient project impact on outfall project: Confirmed projects are independent; nutrient reduction addresses dry weather flow pollutant levels regardless of outfall location

Vice President Leveroni questioned:

  • Progressive design-build for future projects: AGM Robinson explained varying delivery methods selected based on "right method, right project, right time, right team, right location" analysis; some additional progressive design-build projects in development, with nutrient reduction being largest currently
  • BDFP 70% complete vs. remaining appropriations: AGM Robinson clarified appropriations represent authority to spend (not spending plan); most BDFP funds already appropriated; remaining appropriations complete the project
  • Seawall repair at Fisherman's Wharf: Confirmed as Port project not affecting SFPUC outfalls; other Port projects may impact SFPUC outfalls in future

Commissioner Thurlow asked about total project budgets and uncertainty: AGM Robinson explained contingencies vary by project stage per American Association for Cost Estimating standards—up to 100% (or -50%) at early concept stage, decreasing through design, with minimal contingency during construction (especially design-bid-build with hard contractor bids). Higher contingencies applied to projects further out in capital plan; lower for projects in construction.

Commissioner Jamdar clarified Southeast Bay Outfall budget ($1.98 billion total, $154 million appropriations over decade, minimal bar chart representation): Confirmed construction intentionally scheduled beyond 10-year window to avoid overlapping with major projects like nutrient reduction, minimizing ratepayer impact. Not a deferred project; planning active with interim condition assessment and rehabilitation ongoing. Timing also coordinates with Port waterfront sea level rise efforts and potential Army Corps engagement given Islais Creek location.

President Arce's Comments

President Arce commended AGM Prather and team for transparently prioritizing affordability while delivering core services. He highlighted the 20% capital plan reduction ($1.5 billion in deferrals from $7.4B to $5.9B) as critical to addressing rate concerns and helping lower projected rate increases, particularly in near-term, buying time for long-term solutions.

Arce emphasized the line-by-line itemized project list demonstrates transparency in decision-making and noted four key cost drivers the enterprise navigates:

  1. Second-highest construction costs in the world (after New York)
  2. Debt service costs (including interest rates)
  3. Increasing regulatory requirements
  4. Decreased federal support (likely to continue under current administration)

Arce praised AGM Prather's career trajectory from hands-on field work to leadership, expressing full confidence in presented decisions. He acknowledged the entire agency's collaborative effort (finance, infrastructure, wastewater teams, General Manager Herrera) in achieving the budget balancing act.

Public Comment

Francisco DaCosta provided comments on both operating and capital budgets, emphasizing:

  • Importance of informing residents, particularly in District 10/Bayview-Hunters Point
  • Criticized lack of transparency and accountability, claiming millions wasted
  • Referenced controller's office audits from 2002-2022, suggesting poor ratings
  • Questioned why taxpayers are "left out" as budget grew from $6 billion to $15 billion (anticipating $25 billion)
  • Raised concerns about employee treatment and firing of "decent and hardworking" employees
  • Indicated issues may come before San Francisco Inspector General
  • Expressed frustration about artificial turf chemicals and commission responsiveness to public health concerns
  • Noted need to fight for rights at all levels given federal political situation
  • Used inappropriate language (addressed by President Arce with reminder about language policy)
  • Emphasized San Francisco as Muwekma Ohlone land with educated population deserving better regarding health impacts on vulnerable populations

Key Outcomes

  • Operating Budget: Commission received presentation on Wastewater Enterprise operating budget featuring $139 million debt service increase (largest PUC cost driver), five temporary-to-permanent position conversions, and significant new costs for BDFP operations and biogas facility
  • Capital Budget: Commission received presentation on $5.9 billion 10-year capital plan, reduced 20% from September 2024 proposal through strategic deferrals prioritizing affordability

The meeting adjourned following public comment with no formal votes taken (informational hearing only).

Meeting Transcript

Good afternoon. Today's meeting of the San Francisco Public Utilities Commission will now come to order. Ms. Lanier, can you please call roll? President Arce? Here. Vice President Leverroni? Here. Commissioner Jamdar? Here. Commissioner Stacey? Here. Commissioner Thurlow? Here. You have a quorum. Thank you, Ms. Lanier. Before calling the first item, I'd like to announce that the San Francisco Public Utilities Commission acknowledges that it owns and are stewards of the unceded lands located within the ethno-historic territory of the Muekma Ohlone tribe and other familial descendants of the historic federally recognized Mission San Jose Verona Band of Alameda County. The SFPUC also recognizes that every citizen residing within the greater Bay Area has and continues to benefit from the use and occupation of the Muekma Ohlone tribe's aboriginal lands since before and after the San Francisco Public Utilities Commission's founding in 1932. It is vitally important that we not only recognize the history of the tribal lands on which we reside, but also we acknowledge and honor the fact that the Mwekma Ohlone people have established a working partnership with the SFPUC and are productive and flourishing members within the many greater San Francisco Bay Area communities today. Item 3, Public Hearing and Discussion, Wastewater Enterprise Budget and Capital Plan. Good afternoon, Commissioners. President Arce, my name is Joel Prather, and I am the Wastewater Assistant AGM for San Francisco PEC. I'm here today to present our proposed wastewater enterprise operating capital budgets. This is our final budget here in the cycle, and I think it's only fitting that we followed Water's enterprise budget last week. Between these two enterprises, we provide a critical urban water cycle that helps keep our city running. We have a reliable and robust system, and we don't have to look far to see that. A little over a month ago, we experienced a major utility failure that left many San Franciscans in the dark. But throughout that unfortunate event, fresh water came out of the tap, and the toilets kept flushing. So last week, we got to hear from water what made that happen, and this week, we'll go to the other side of the pipe to hear from wastewater. So with that, can I have the slides, please? And actually, before we jump into the deck, I do want to note what we're covering today. And so first, I will be presenting item 3A-I, which is the Wastewater Enterprise Operating Budget. After that, we'll stop for questions or comments. and then I will proceed to item 3BI, which will be our enterprise capital budget, which we'll stop at the end of that for comments and questions as well. Wastewater Enterprise, here's an overview of our enterprise. Our mission is to manage our wastewater system to protect public health and the water quality of the Bay and Ocean. We value environmental community interests, and we sustain the resources that are entrusted in our care. We do this through operating the San Francisco PUC's combined sewer system. We are the only combined sewer system on the coast of California, one of few on the entire West Coast, the other two being Portland and Seattle. But we're actually one of over 700 throughout the United States.
