Utility Billing

Irrigation Shut Off

The 2017 Irrigation Shut Off is scheduled for July 17th – 29th. All unpaid irrigation accounts will have their water terminated. Delinquent irrigation accounts may take up to 7 days to be turned back on after payment is made.

PLEASE NOTE: As of June 30, 2017, a $40 late fee and a 2% penalty have been added to all delinquent 2017 irrigation assessments. Any outstanding assessments for prior years have had additional interest added. 

Quick Payment Feature

You can now make a one-time payment without having to register. Just go to https://nampa.merchanttransact.com/Bills/Default.aspx , enter your account number, and click on Make Payment. Enter your payment information and submit. A receipt will be e-mailed to you. There is no fee for this service.

Nampa Shares & Cares

In this challenging economy, many Nampa families are having a hard time making ends meet. The City of Nampa’s Utility Billing office has joined forces with Western Idaho Community Action Partnership (WICAP) to launch the Nampa Shares and Cares Program.

By adding a tax-deductible donation to your bimonthly city utility bill, you can help someone less fortunate pay their water and sewer bill. 100% of your donation will be used to help those in need.
