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.Irrigation water supplied through our irrigation system is a necessary and critical resource to farmers, homeowners, and businesses in our community. Nampa residents are asked to check the programming of their sprinkler control box to ensure they are not unknowingly over-watering. If customers notice a leak, they are encouraged to call the 24-hour hotline at 208-468-5860. Please know that due to the volume of calls, it may be necessary to leave a voice message. Staff will return calls as soon as possible.
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.
