Waterworks Division
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.

The City of Nampa will begin shutting down its irrigation system Monday, Oct 5th, 2015.  By Friday, Oct 9th, all pumps should be off.  The majority of Nampa's irrigation water comes from the canals operated by Nampa-Meridian Irrigation, Pioneer Irrigation District and Boise-Kuna Irrigation.  Nampa is scheduling the end of its season to coincide with the end of water delivery by two of the districts.

Nampa-Meridian has scheduled Oct 1st for the end of their season followed by Pioneer ending its season approximately Oct 6th.

A reminder to individuals and companies blowing out sprinkler lines, please do not turn off the city valve on your property.  That keyed turnoff is for city use only.
