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.”

PREPARING FOR THE FUTURE

As we look ahead, our key priorities include replacing aging infrastructure, meeting new regulatory requirements, and enhancing environmental sustainability while continuing to provide exceptional service.
This past year, the San Francisco Bay Regional Water Quality Control Board introduced new regulations requiring all Bay Area wastewater agencies to reduce nitrogen discharges to the Bay by 40% within a decade. Achieving the mandated reductions will require significant treatment upgrades at an estimated cost of $11-13 billion for Bay Area residents. Costs to Central San to meet the 40% nitrogen reduction may range from $500-700 million. We are exploring innovative solutions to help us meet the new requirements, and reprioritizing other projects to control overall costs and minimize rate impacts to customers.

To ensure fair rates, Central San completed a Cost of Service Study to assess the costs of providing sewer service to all of our customer classes.

The Central San Board of Directors will hold a public hearing on the proposed rate increases at 2:30 p.m. on April 17, 2025. However, at the public hearing on April 17, District staff will recommend that the Board receive and consider any comments as a part of the public record, but to take no final action on the proposed rate increases. Rather, the April 17 public hearing will be continued to May 22, 2025, at 2:30 p.m. The reason for the continuance from April 17 to May 22 is that a revised public hearing notice was sent to Permitted Industrial Users with the May 22 hearing date, and it is the District’s goal to consider and take action on all proposed rate increases at the same public hearing on May 22, 2025.

The notice of the April 17 hearing was mailed to all property owners and customers within Central San’s service area. The notice of the May 22 hearing (Updated Rate Notice 2025) was mailed to all property owners and customers who are Permitted Industrial Users.

Therefore, the District Board will consider all proposed rate increases on May 22, 2025, at 2:30 p.m.
