The Waterworks Division provides Nampa residents with over 6.8 million gallons of safe drinking water each day. The 28 Waterworks employees assure this supply by maintaining and repairing of over 800 miles of water lines and 15,000 water valves. Staff also attends to 28,000 domestic water services and meters.
Provide a safe, clean supply of potable water and an abundant supply of irrigation water by the most efficient means possible, while delivering exceptional customer service.
Provide both domestic and irrigation water in such abundance that will secure the City of Nampa’s prosperity for decades to come. To accomplish this we will install the best infrastructure available to us, remove and upgrade those items that don’t meet our high standards of excellence, continue to improve our processes and treat our customers with the highest level of service possible.
Irrigation districts announce water release dates; city irrigation water won’t be ready until mid-April
The city of Nampa will begin its irrigation season by filling the pressurized system on April 2. Full pressure is not to be expected until mid-April.
Nampa Meridian Irrigation District, Boise-Kuna District and Pioneer Irrigation District plan to release water into the canal systems on April 2, however, it could take up to two weeks before the water is available for pump operations.
City of Nampa irrigation customers should have irrigation water at full pressure by mid-April after crews have tested lines, flushed the system and brought ditch pumps on line. As crews find problems with water lines they shut them down for repairs, this can result in customers having water one day and not the next, so patience is requested.
If you notice a leak please call 468-5860. This is a 24-hour a day phone number. Due to the volume of calls, if you get our voice mail please leave a message. We will call you back as soon as possible.
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.
