Water Rates
Dublin San Ramon Services District (DSRSD) provides drinking water to nearly 100,000 people within the City of Dublin and the Dougherty Valley area of the City of San Ramon.
DSRSD purchases its supply of wholesale treated water from Zone 7 Water Agency. DSRSD also partners with the East Bay Municipal Utility District (EBMUD) to produce and distribute recycled water to nearly 360 sites through the DSRSD-EBMUD Recycled Water Authority (DERWA).
Table A – Retail Consumption Charges
These volume-based charges cover the cost of potable water purchased from Zone 7, power, and recycled water. Volume is measured in hundred cubic feet (CCF). One CCF is equivalent to 748 gallons of water.

Table C – Zone 7 Consumption and Fixed Charges
DSRSD purchases all of its potable water supplies from Zone 7 Water Agency (Zone 7). Zone 7’s wholesale rates are comprised of fixed and variable charges. DSRSD must pay Zone 7 the fixed charge regardless of the amount of water sold. Currently, DSRSD blends the fixed and variable wholesale water rates to develop the “Zone 7 Cost of Water” charge and passes through the charge as a variable consumption charge to DSRSD customers. The proposed Zone 7 Cost of Water charge separates the current blended charge into a fixed charge and a variable charge for wholesale water. This proposed methodology allows DSRSD greater revenue stability.

Table D – Water Shortage Condition Charges
DSRSD’s Water Shortage Contingency Plan(PDF, 382KB) prepares the District to respond to water shortages caused by drought or emergencies. It includes actions to reduce water usage by certain percentages based on the severity of the water shortage. Water shortage condition charges ensure that DSRSD generates enough revenue to cover the cost of providing water during times of water shortage when water deliveries are reduced.

Table E – Dougherty Valley Incremental State Water Project Charge
Dougherty Valley (San Ramon) Customers only
The State Water Project (SWP) is the primary water source for Zone 7 (the District’s sole drinking water supplier). Zone 7 recovers a portion of the cost of purchasing SWP through property taxes levied in Alameda County. Dougherty Valley’s share of the SWP costs is collected through DSRSD’s retail water rates, the Dougherty Valley Standby District Charge (Standby Charge), and the Dougherty Valley Incremental State Water Project Charge (Incremental Charge). The Standby Charge and Incremental Charge appear on the Contra Costa County secured property tax rolls, respectively as “DSRSD-DRTY VLY 01-1” and “DSRSD DRTY VLY SWP.” The Standby Charge has been fixed at $170.75 (annually) since 2019, while adjustments are made annually to the Incremental Charge based on the Dougherty Valley Incremental State Water Project Charge Annual Report.

Rate Change
In addition to any rate increases adopted by Zone 7 Water Agency, water rates generally increase each year on Jan. 1 based on the annual change in the Consumer Price Index (CPI, All Urban Consumers for San Francisco-Oakland-Hayward).
The DSRSD Board of Directors may change rates at other times as a result of rate studies or other factors. DSRSD notifies customers when rate changes are proposed, as required by Proposition 218(PDF, 184KB). Customers are encouraged to attend public meetings regarding rate changes and submit written comments. For more information on Proposition 218, see the following guides:
