Irrigation - The City recommends having a shut off valve installed in your line so that you can turn your service on and off as needed. Curb stop valves are owned by the City of Nampa and are to be used by City employees in emergencies only.

Domestic - Please contact the Waterworks Division to come out and shut off your meter.
