Supervisors delay decision after hours of testimony on SFPUC tiered water rates and $4.3B WESIP

The Government Audit & Oversight Committee heard extended testimony on the San Francisco Public Utilities Commission’s proposed three-tier residential water rate for single-family households and the Water System Improvement Program (WESIP), a multi-billion-dollar capital program the PUC says will fund seismic upgrades and system reliability. Faced with hours of technical presentations and a packed public-comment period, the committee continued the hearings for one week to allow further analysis and negotiation while remaining within the board’s 30‑day window to accept or reject rates.

SFPUC General Manager Susan Liao told the committee the proposed rates had been vetted through a Rate Fairness Board and roughly 50 community meetings. Deputy General Manager Tony Irons described the Water System Improvement Program as a multi-project capital program now estimated at $4.3 billion including financing; he said 20 of 34 regional projects are in full design and the program is "on schedule" and "on budget" in staff projections. Irons and other staff stressed the need to proceed with design while environmental review and federal permitting (including Army Corps permits referenced) proceed for construction phases.

PUC water enterprise staff and the budget analyst presented rate modeling and customer-class breakouts. SFPUC staff said most single‑family customers would fall in the first two tiers; the budget analyst offered alternate calculations showing differences between customers (count) and usage (volume) breakdowns and highlighted that revenue neutrality assumptions materially affect distribution of increases. PUC staff emphasized that multifamily customers are billed through master meters to property owners, complicating a straightforward tiered signal to individual end users; they said the commission is studying alternatives for multifamily and nonresidential classes and noted that wholesale master water-sale contract negotiations provide leverage for broader conservation measures.

Public comment ran for more than an hour and produced sharply divided views. Environmental groups and conservation advocates (including NRDC, Tuolumne River Trust and Clean Water Action) supported a conservation-based, tiered structure and pointed to low-income and large-family relief mechanisms. Numerous residents and neighborhood organizations (including Coalition for San Francisco Neighborhoods and multiple neighborhood associations) called the proposal discriminatory because it applies only to single-family metered households and urged alternatives such as uniform volume rates, stronger tenant-conservation measures, or different wholesale/contract provisions. Several speakers raised equity and legal concerns and asked for clearer transparency on how revenues will be used.

Given outstanding technical questions on usage distributions, customer impacts, and a raft of public testimony, the committee chose to continue the hearing for one week to allow the PUC and budget office to refine analyses and to return within the statutory window for a decision.
