Central San receives revenue in order to recover the costs associated with collection, treatment, and development. To learn more about these rates and charges, please see the information below. 

Annual Sewer Service Charge

Central San collects an annual Sewer Service Charge from each property connected to the sewer system. For most property owners, the charge is billed on the Contra Costa County property tax bill and is labeled “CCCSD SEWER CHG.”

The annual Sewer Service Charge covers the collection and treatment of wastewater and other activities described in the Proposition 218 notice mailed to property owners.

The State Controller’s Property Tax Postponement Program allows homeowners who are seniors, are blind, or have a disability to defer current-year property taxes (including the sewer service charge) on their principal residence if they meet certain criteria.

The Low Income Household Water Assistance Program (LIHWAP) is a federally funded program that offers a one-time payment to help you pay residential water or wastewater bills. LIHWAP may be able to help you pay your Central San Sewer Service Charge. 

Environmental and Development-Related Fees and Charges

Capacity Fees

A Capacity Fee is charged for new construction projects or for the expansion of a non-residential facility which may result in an increased wastewater burden. The Capacity Fee charges new customers for their share of Central San’s assets that were paid for by existing customers. This methodology is known as “equity buy-in.”
