Irrigation Districts

The majority of Nampa’s irrigation water comes in the canal system from Lucky Peak. The Pioneer Irrigation District and the Nampa Meridian Irrigation District manage most of the canals and ditches in Nampa. In some cases these irrigation districts are solely responsible for the infrastructure leading to a customer’s property.

City of Nampa Pressurized Irrigation

In many subdivisions the City of Nampa Waterworks Division is responsible for the pressurized irrigation pump station, water main line, and curb stop valves.

The service line, which is between the curb stop and the sprinkler head, belongs to the property owner. The City will not repair a customer’s service line.
