Where can I find how much I pay for sewer service?

DSRSD bills single-family dwellings for wastewater service on the owner’s annual property tax bill. The service charge will be listed as DSRSD SEWER SVC on the property tax bill as follows:
For Alameda County residents, look under Fixed Charges and/or Special Assessments.

For Contra Costa County residents, look under SPECIAL TAXES & ASSESSMENTS.

Newly constructed single-family dwellings may be billed bimonthly until the next property tax bill. All other customers are billed bimonthly.

Industrial Rates

Charges for significant industrial customers are not estimated by customer class, but calculated individually according to the load that their wastewater places on the Regional Wastewater Treatment Facility (regional charges) and the wastewater collection system (local charges). The customer’s load is measured by calculating the amount of wastewater (“flow,” typically measured by the amount of water purchased from DSRSD less the amount used outdoors), the biochemical oxygen demand (“BOD,” a measure of the amount of organic material in the wastewater), and the quantity of suspended solids (SS) that must be removed.

Customers will see regional and local charges for “loading” and “demand” on their bimonthly bills. Loading charges are based on the quantity and composition of the customer’s recorded discharge for the billing period. Demand charges are based on capacity that the customer has reserved in the wastewater treatment system. If this capacity is exceeded, higher demand charges will apply. See District Code Section 5.30.020 for more information.

In addition to the service charges listed above, customers participating in the District’s Industrial Pretreatment Program pay fees that reflect the DSRSD staff effort involved in permitting, monitoring, and lab analyses. All industrial customers complete an Industrial Waste Discharge Permit Application to determine whether they are required to participate in the program. Contact the Senior Environmental Compliance Inspector at (925) 875-2335 regarding industrial wastewater rates, the Pretreatment Program, or the permit.

Rate Changes

After an evaluation, the District concluded that no rate increase is necessary on July 1, 2016. The District bases its wastewater rates on the cost of providing service to each class of customer and rates usually increase each year on July 1.

The DSRSD Board of Directors may change rates at other times as a result of rate studies or other factors. Customers are notified when rate changes are proposed as required by Proposition 218. Customers are encouraged into attend public hearings regarding rate changes and submit written comments. For more information on your rights to protest rate changes, see:
