Nampa city irrigation water is to be expected in full pressure by Mid-April.
The City of Nampa will begin its irrigation season by filling the pressurized system on April 3.
Nampa Meridian Irrigation District, Boise Kuna District and Pioneer Irrigation District plan to release water into the canal systems on April 3, however, it could take up to two weeks before the water is available for pump operations.
All Nampa residents are asked to check the programming of their sprinkler control box to assure they are not unknowingly over-watering. Those who need help setting a sprinkler control box should contact a lawn care professional. Residents are also strongly encouraged to install their own shut off valve to control sprinkler lines and not to operate the city valve as this is for emergency use only.

Frequently asked irrigation questions and more information on the irrigation season and assessment.
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.
Water is a valuable resource in our community, for this reason over watering violates City Code.
