Paying your water bill

Account responsibility

It is the responsibility of the property owner to ensure payments are made in full every month by their tenants to avoid a disconnection or possible property lien. 


If payment is not received by the payment due date shown on the utility bill, a Notice of Intent to Disconnect Water will be mailed to the customer. Prior to utility service reconnection, all charges due shall be paid in full. (Municipal Code 13.14.070) Once full payment is received in our office at 175 Kellogg Court, service will be scheduled for reconnection by the end of the next business day.
