San Francisco water, sewer bills rise July 1, 2026: SFPUC estimate
San Franciscans will see higher water and sewer charges starting July 1, 2026, after the San Francisco Public Utilities Commission (SFPUC) updates its rate schedule for fiscal years ending 2027 and 2028. SFPUC estimates that the average single-family household’s combined monthly bill increase will be about $21 in fiscal year 2027 and about $23 in fiscal year 2028—an annual impact of about 12.6% and 12.5%, respectively.
Local reporting from ABC7 puts the same first increase into a different “starting bill” frame: it reports SFPUC estimates the typical monthly water-and-sewer cost rises from about $171 to about $189 beginning July 1, 2026.
The typical monthly impact: $21–$23 more, depending on the fiscal year
SFPUC’s rate materials describe a combined monthly bill increase for the average San Francisco residential household of $21 in fiscal year 2027 and $23 in fiscal year 2028, with the combined annual impacts estimated at roughly 12.6% and 12.5%.
ABC7’s resident-facing translation of the first increase uses a “current-to-new” estimate for an average single-family home: about $171 per month before the change, rising to about $189 per month coming July 1, 2026.
Because both sets of figures are based on an “average” household, they’re best read as ballparks—not guarantees. Individual bills can differ based on meter size and water use.
What’s actually in the bill: fixed charges plus usage-based charges
SFPUC describes water and sewer bills as having two core elements:
- Fixed charges that cover shared costs relevant to all customers.
- Usage (volumetric) charges based on the amount of water used and the wastewater volume associated with that usage.
This helps explain why bills don’t always track water consumption perfectly: even if your usage drops, some parts of the total bill can remain steady because they’re fixed.
On the usage side, SFPUC notes that residential water rates are billed based on metered water usage with tiers. For wastewater, SFPUC says residential wastewater rates are billed based on an estimated volume of water that returns to the sewer system. For single-family residences, the default is 90% of water usage for that wastewater estimate.
Water vs. sewer: where the percentage increases differ
ABC7 reports that the July 1, 2026 increase includes different percentage changes for water and sewer: water rates rise 7% and sewer rates rise 15%, for an estimated average combined bill increase of 10.5%.
Those percentages provide context, but residents will still want to look at their own bill components—fixed vs. usage-related—when estimating their change.
How to estimate your own bill (instead of relying on averages)
SFPUC provides an online bill calculator to estimate what your bill would look like at current rates versus proposed new rates. To use it, start with what’s on your most recent bill—especially:
- Your meter size (which affects water service charges),
- Your metered water usage for the billing period (which affects tiered water rates), and
- Whether you’re seeing the residential wastewater default used in the calculations for single-family accounts.
The goal is to match SFPUC’s “average household” math to your actual account details.
Who reviews rate changes like this?
SFPUC’s rate process includes public oversight from the Rate Fairness Board. SFPUC says the board has been reviewing and advising on rate matters since 2002, and that it includes appointed members such as local residents and business owners. SFPUC also says these meetings are held throughout the year in-person and remotely by teleconference, with instructions and materials posted through the agenda.
Bottom line for residents
Starting with bills that reflect the new rate schedule effective July 1, 2026, SFPUC expects typical single-family customers to face higher monthly water-and-sewer charges—about $21 in fiscal year 2027 and about $23 in fiscal year 2028. ABC7 frames the first change as roughly $171 to $189 per month for the average single-family home.
If you’re budgeting and the number feels higher than expected, use SFPUC’s calculator and your own account details—because fixed charges and tiered, usage-based billing mean two households can use similar amounts of water and still see different total changes.
