Water & Sewer Services

The Town of Hillsborough bills for water and certain sewer services. Residential sewer accounts are billed and collected by the San Mateo County Controller's Office through the property tax billing.

Water Billing

Most residential customers are billed bi-monthly. Some residential and all commercial (schools and clubs) customers are billed monthly. Bills are due upon receipt and considered delinquent after 30 days of mailing the invoice. A penalty of 10% and interest will be assessed on delinquent accounts.
