Transition to Sewer Service Charges to County Tax Roll

In the past, customers have received bi-monthly bills (six bills total) for these services. Beginning in July 2023, the City switched to semi-annual billing (two bills total) and will collect the charges on the property tax and assessment bill sent out by the County.

This change does NOT cause an increase in your current sewer service charge.

Billing through the County tax roll is anticipated to provide benefits to both ratepayers and the sewer enterprise fund. As the collector of general taxes, the County of San Mateo guarantees payment for any charges collected on the tax roll. This guarantee of payment allows staff to project revenue with more accuracy and plan any future expenditures required to maintain the City’s sewer collection system, including any long-term debt obligations.

Charges collected through the tax roll are the responsibility of the parcel owner. Customers do not have the ability to opt-out of the transition.

If you have any more questions, you can contact Mike Sung, Finance Director, by calling 650-259-2433.
