Frequently Asked Questions


Why Several Years of Increases? 

These increases were recommended after an extensive water rate study that found serious deficiencies in our water delivery system. Nampa’s aging water system has worked silently for years without significant pipe replacement but now it is time to reinvest. Without reinvestment, we could be headed for a water crisis characterized by unplanned outages, emergency repairs and even higher costs. Emergency repairs can cost 15 times more than planned replacement because they frequently require overtime staff hours, result in property damage, and can occur under newly paved roadways. 


Pre-increase funding barely covers operations and basic maintenance costs. An additional $33.4 million will be needed over the next 10 years. Increases will fund ongoing replacement of nearly 470 miles of domestic pipeline (some of which is over 100 years old), upgrading pumps to bring water from its source to your home, increasing supply and maintaining water quality to ensure clean, safe, drinking water.

Projects to be funded with the rate increase.

 Rates are different for residential and commercial properties. Please note that some residential customers live in either non-single family or even commercial or industrial zones -- and those rates are higher. If you have questions about your water bill, call (208) 468-5711 or send an email to:
