Make One-Time Payment
Pay your bill in 3 easy steps without registering. All you need is your account number from your paper bill.
Payments made prior to 5PM PST will be posted to your account next day. Payments made after 5PM PST will be posted within 48 hours. For each payment, you will receive a confirmation number for your records.
From February 3 through February 14, all payments made online through Paymentus will be processed on the payment date. However, payments will not post to water customer accounts until February 14th as the City of Napa transitions to a new water billing system. No late fees or penalties will be assessed due to this delay in payment posting.
