SFPUC considers sewer‑lateral inspection, point‑of‑sale and insurance options amid aging network
Summary
The San Francisco Public Utilities Commission reviewed data showing more than 160,000 sewer laterals (avg. age ~70 years), discussed homeowner vs. city responsibility at the curb, and directed staff to issue an RFP to evaluate insurance, point‑of‑sale inspection and other program options within roughly 30 days.
The San Francisco Public Utilities Commission on Sept. 13 heard a detailed presentation on the city’s sewer‑lateral system and moved to seek outside evaluation of program options to address aging infrastructure.
Tommy Waller, assistant general manager for wastewater, told commissioners the utility is responsible for the lower lateral up to the curb while homeowners are responsible for the lateral between the curb and the building. "We have over 160,000 sewer laterals," he said, noting the system represents about 900 miles of pipe and that the average lateral is roughly 70 years old. Waller said the utility’s three‑year average spending on laterals and related replacement is about $34 million, with an average replacement cost for a lower lateral of roughly $15,000 and about $3,500 for the homeowner portion.
Commissioners pressed staff on the legal basis for the curb‑boundary policy. Deputy City Attorney Josh Milstein said he did not have the historical policy rationale at the meeting and committed to providing the ordinance or policy language requested by the Commission.
Staff outlined several program options in use elsewhere — an insurance‑style program, mandatory inspections at point of sale, or a hybrid approach — and stressed the need for clear homeowner outreach and contractor guidance. Commissioners emphasized equity concerns tied to the ongoing rate increases and warned against abruptly shifting large costs to property owners without careful design.
As a next step, commissioners directed staff to issue an RFP within about 30 days to bring back vendor proformas and policy options. "We will probably put out an RFP within the next 30 days," staff said, and estimated a roughly six‑month evaluation period once a vendor is onboarded. The Commission said it will consider how any recommended approach would interact with existing moratoria on street cuts, point‑of‑sale disclosures and potential financing support for low‑income households.
The item remains policy development rather than final action; staff will return with concrete recommendations and estimated costs after the RFP process.
