SFPUC presents $5.9 billion wastewater capital plan and flags $139 million debt-service jump

San Francisco Public Utilities Commission members on (date not specified) received a detailed presentation of the Wastewater Enterprise operating budget and a proposed 10‑year capital plan totaling roughly $5,900,000,000. The agency said the plan was pared back from about $7,400,000,000 through targeted deferrals intended to limit near‑term rate impacts.

The presentation, led by Wastewater Assistant General Manager Joel Prather, outlined operating requests such as several temporary‑to‑permanent position conversions and equipment, and identified a major budget driver: an estimated $139,000,000 increase in debt‑service obligations. ‘‘We operate three wet‑weather treatment plants…and treat approximately 34,600,000,000 gallons of wastewater in a typical year,’’ Prather said, summarizing system scale and the demands behind the request.

Why it matters: the capital plan funds projects tied to regulatory compliance, public‑health protections and climate resilience. Major projects highlighted include the Southeast Plant nutrient‑reduction program (the single largest cost item in the 10‑year plan), force‑main and pump‑station rehabilitation (including the aging Channel Street Force Main), Ocean Beach climate‑adaptation work to protect coastal wastewater assets, Oceanside plant capacity and seismic upgrades, and the near‑completion biosolids digester facility project (BDFP).

Key budget details and near‑term asks - Capital plan: presented as approximately $5,900,000,000 over 10 years after prioritization and deferrals from a higher prior total. Prather said the reductions represent deferrals, not deletions of needed work. - Debt service: staff identified an estimated $139,000,000 increase in debt service as the single largest year‑over‑year driver of the PUC’s budget increase. - BDFP and biosolids: the BDFP solids‑processing upgrade is described as more than 70% complete; commissioning and testing are expected to begin this year with operational startup targeted in 2027. Prather said the digester work will increase power demand (roughly 2.6 megawatts for the digester and an additional ~1.6 megawatts for the biogas facility) and will require additional chemicals; staff proposed a $2,600,000 increase to the existing PUC Power work order and an ongoing $1,500,000 chemical cost beginning in a later fiscal year. - Biogas utilization: the new facility is intended to convert digested gas to pipeline‑quality gas for injection into a nearby PG&E pipeline on Gerald Avenue; staff requested about $1,000,000 per year for the first five years to contract O&M for specialized equipment. - Systems and maintenance: requests include an ongoing annual maintenance/standalone line for the Foxboro distributed control system (reported in the presentation as $712,000 annually after correction), lab asset management investments, and equipment/furnishings for renovated facilities.

Commissioner questions and staff responses Commissioners pressed staff on several technical and financial points. Commissioner Stacy asked whether ‘‘attrition savings’’ reflected vacant positions; Anna Dunning (Budget Director) explained attrition is a technical budget offset that captures typical salary savings from turnover and can be used to offset costs of converting temporary staff to permanent FTEs. Commissioner Thurlow and others asked why revenue‑funded capital appears to decline while debt‑funded spending rises; Erin Corvinova (Financial Planning Director) and CFO Laura Burchzyk said some projects are legally limited to revenue funding, while large wastewater investments moved earlier in the planning cycle have required more debt funding sooner, bringing near‑term debt service obligations online.

Project delivery and timing Staff described using progressive design‑build for the nutrient‑reduction work to reduce redesign risk and accelerate contractor engagement. Prather said the Southeast Bay outfall has an estimated total budget of $1,980,000,000 but that major construction is planned beyond the 10‑year window to avoid overlapping other large projects and to coordinate with port and Army Corps waterfront planning.

Public comment and next steps During public comment, speaker Mister DeCosta criticized transparency and accountability in Bayview‑Hunters Point budgeting and audits and urged needs assessments, saying residents are ‘‘fed up.’’ No votes were taken on rates or final adoption of the capital plan at this meeting. The agency indicated additional presentations and specific project approvals (for example, progressive design‑build authorization for nutrient reduction) will come to future meetings; staff did not request immediate adoption of rates at this session.
