City of Vacaville Utility Billing
PO Box 6180 
Vacaville CA 95696-6180

Late Notices
Your utility bill is due upon receipt and will become past due if not paid by the date on the bill. A late fee of 10% or $10, whichever is greater, will be added to your account if it becomes late. If your bill remains unpaid, a processing fee will be charged and a service interruption notice will be mailed indicating a service discontinuation date. If unpaid, your service will be interrupted and an additional processing fee will be added for non-payment.

What do I do if my water is disconnected due to nonpayment? 
In order to resume or continue service that has been interrupted for non‐payment, the customer must pay all delinquent charges and fees owed. To have same day restoral without paying an after-hours restoral fee, the payment must be received by 4:00 pm. Water service that is turned on by any person other than City personnel may be subject to fines or additional charges. Any damages that occur as a result of unauthorized restoration of service are the responsibility of the customer.

Returned Payment
In the event the City receives notification of a returned payment, the customer’s account will be considered unpaid.  The City will assess a returned payment fee as set forth in the Service and Facility Rental Fees schedule.  The customer of record will be sent a notification of the returned payment.  If at the time of the returned payment the account is less than 60 days delinquent, the notice will state the date the returned payment and fee must be paid to avoid additional notifications and fees.  If at the time of the returned payment, the customer’s account is more than 60 days delinquent, a 7 business day notice of service interruption will be mailed to the customer of record.

In the event a customer makes payment to restore water service previously interrupted for non‐payment and the City receives notification that said payment was returned, the City may promptly issue a 48‐hour notice of service interruption.
