Rates & Fees
Annual Sewer Service Charge
Central San collects an annual Sewer Service Charge from each property connected to the sewer system. The current residential rate is $598 per year for a single-family residence and $566 per year for a multi-family residential unit. 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 Sewer Service Charge is billed for the upcoming fiscal year. For most non-residential customers, the charge is based on their water consumption for the prior calendar year.
The schedule of annual Sewer Service Charges can be found in the

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 is calculated using the equity buy-in method. Under this method, new customers are charged for their share of Central San’s assets at the same equity position as existing customers.
Capacity Fees for residential projects are calculated on a per-residential unit basis. Capacity Fees for most non-residential projects are calculated based on the business type and building square footage.
