Missoula Water


Due to extensive U.S. Postal Service delays, Missoula Water customers may receive their water bills later than usual. In response, Missoula Water will not be assessing late fees or shutting off service due to late payment. We are looking at various solutions to this problem and appreciate your patience.

Please note that customers may pay their bills online or sign up for e-billing by visiting https://utilitybilling.ci.missoula.mt.us/.


Welcome to Missoula Water! We provide drinking water, irrigation and fire protection to the citizens of the Missoula community.

Just below Missoula is one of the finest sources of groundwater in America, the Missoula Valley Aquifer. It’s an incredible source of clean, fresh water, but in some places it’s no deeper than 40 feet below the surface, making it very susceptible to contamination. Let’s all work together to keep our water clean and protect our most valuable resource.


Please continue to pay your water bill, or as much of it as you can, because you are still responsible for all water charges incurred during this time. If you are unable to pay, please submit the COVID-19 "Vulnerable Individuals" Form listed below to watercs@cs.missoula.mt.us. The lobby at the Missoula Water building on W. Broadway will remain closed. 

Please use any of the following methods to pay your water bill:

Billing and Service

There are two types of billing methods for water service: Metered or Flat Rate and both are billed on a monthly basis. All new structures are required to have meters, therefore most homes in Missoula have metered service.

  • Metered Service: Customers are billed according to a fixed rate based on meter size in addition to your water usage for the month. Many of our customers prefer metered usage as their conservation efforts are reflected by a savings on their bill.
  • Flat Rate Service: Customers are billed a flat fee based on the number of rooms, baths and toilets in the home, and not based on actual consumption. There is also a separate flat rate sprinkling charge based on the square footage of the yard.

 If you are interested in changing from a flat rate to a metered rate, please contact our Customer Service Department.
