City of Nampa irrigation to be shut off October 6

The City of Nampa will shut down its irrigation system Tuesday, October 6 to coincide with Nampa & Meridian Irrigation District’s October 6 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 tentatively wrap up October 7.

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.

For more information, visit http://www.cityofnampa.us/water or call (208) 468-5860.



Customers needing assistance setting a sprinkler control box are encouraged to contact a local landscaping professional. Residents are also strongly encouraged to install their own shut off valve to control sprinkler lines and are asked not to operate the city valve, as this is for emergency use only. 

The City of Nampa receives the majority of its irrigation water from canals and ditches supplied from mountain reservoirs like Arrow Rock, Lucky Peak, and Anderson Ranch. Pumps draw water from the canals and ditches to provide pressurized service to customers. The length of the irrigation season is dependent on water in the reservoirs and canals.

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.  

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.
