HHW drop-off is available for residents with no appointment needed. Please be aware of possible service delays as we are operating in a different manner in order to keep the health and safety of our employees, our customers, and our community as our highest priority.
Sewer Overflow Prevention
Keeping wastewater in the sewers is the job of Central San’s Collection System through cleaning, maintenance and repair of 1,500 miles of underground sewer lines. You can help by making sure that your side sewer – the connection from your home to the public sewer – remains free of any blockages.
Construction Zones
Central San strives to ensure that our collection and treatment systems operate in the most efficient manner possible. Through an aggressive capital improvement plan, we initiate projects to upgrade our infrastructure and utilize the most advanced, cost-effective equipment and processes available. As these projects develop, we’ll keep you informed about them through this section of our site.
Earthquake Preparedness
It’s no secret that California is prone to earthquakes, and Contra Costa County is home to many earthquake faults. Below you will find some links to important information to help you prepare for an earthquake, and deal with its aftermath.
Rates, Fees, and Charges
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 $660 per year for a single-family residence and $625 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.”
