Pressurized Irrigation: Information
Irrigation Turn Off Dates
News (September 19, 2019)
City of Nampa irrigation to be shut off October 4
The City of Nampa will shut down its irrigation system Friday, October 4 to coincide with Nampa & Meridian Irrigation District’s October 7 shut-off.
Nampa & Meridian Irrigation District is one of three providers for most of Nampa’s irrigation water. The Boise-Kuna Irrigation District is scheduled to end its season October 7 and Pioneer Irrigation will wrap up tentatively October 11.
The Nampa Waterworks Division reminds individuals and companies that the city valve should not be turned off when blowing out sprinkler lines. The keyed turnoff is for city emergency use only.
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.
