San Francisco Public Utilities Commission (SFPUC)
For SFPUC water and sewer accounts. Match the provider on your bill; this is not a directory of every Bay Area water provider.
Choose the annual report for San Francisco water customers. The same directory separately lists the regional system, Treasure Island and Town of Sunol; these are separate report systems and do not establish a wider service area here.
Service area: SFPUC water/sewer customers in San Francisco. Other regional water suppliers and separately listed water systems require their own provider information.
- Availability · Separate listed reports; no Sunol, regional or Bay Area customer coverage is inferred for this San Francisco entry
