San Francisco Proposed Water and Sewer Rates: Commercial Accounts Should Watch April 2026
SFPUC scheduled an April 28, 2026 hearing on proposed water and sewer rates for fiscal years ending 2027 and 2028. Here is what commercial properties should model now.
Key Takeaway
SFPUC scheduled an April 28, 2026 public hearing on proposed changes to San Francisco water and sewer rates for fiscal years ending 2027 and 2028. Commercial customers should model the proposed rate path before budget season because San Francisco is already one of the highest-cost water and sewer markets.

What changed
SFPUC opened a Proposition 218 process for proposed water and sewer rate changes covering fiscal years ending 2027 and 2028. The public hearing was scheduled for April 28, 2026.
This is a watch-list story rather than a final-rate story. For high-use commercial accounts, proposed rates matter because budget decisions often happen before the first higher bill arrives.
Commercial impact model
San Francisco commercial water and sewer bills can already exceed national averages. A property paying $12,000/month should model each 5% increase as $600/month or $7,200/year. At 10%, the annual exposure becomes $14,400.
Because sewer and water charges both matter, a facility should model the combined bill, not only the water commodity rate.
What operators should do
Before adoption, benchmark usage by meter, identify irrigation and cooling loads, and separate controllable process water from unavoidable domestic use.
If the proposed rate path is adopted, every avoided kGal becomes more valuable. This is the right moment to build the Smart Valve ROI case while finance teams are still setting the 2027 operating budget.

Use your current monthly bill or kGal usage to estimate how much metered-volume reduction could offset this local rate pressure.
FAQ
Are San Francisco 2027-2028 water and sewer rates final?
The SFPUC page describes proposed water and sewer rates and an April 28, 2026 public hearing. Customers should review final commission action before treating rates as adopted.
Why should commercial accounts care before rates are final?
High-use accounts need time to model operating expense, identify volume reduction projects, and prepare budget requests before higher bills arrive.
