City of Nampa Residents Expected to Receive
Irrigation Water by Mid-April
As an essential service, the City of Nampa will begin its irrigation season April 1, and customers can expect full pressure by mid-April after crews have tested lines, flushed the system, and brought ditch pumps on line. Crews will work to ensure the water lines are functioning properly and may need to temporarily shut down a line for repair. Temporary closures may interrupt irrigation service for customers, and patience is appreciated.
Nampa Meridian Irrigation District plans to release water into the canal systems April 6, Pioneer Irrigation District on April 11, and Boise-Kuna Irrigation District’s dates are still to be determined.
Although the irrigation bills have a due date of April 1, 2020, customers have until June 30, 2020 to pay without accruing any late fees or penalties on the current year’s assessment.
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.
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.
