On July 20, 2020, Missoula City Council approved a new wastewater rate structure. The new rate structure allows for Sewer Use Fees to be included on a combined monthly utility bill beginning with the February 2021 billing cycle. The new wastewater rate structure was required to make the billing structure compatible with the current utility billing system software.
Under the new rate structure, all accounts are billed using a base rate plus a volume rate that is based on water consumption. Water consumption for residential customers is calculated using the customer’s wintertime average water usage for October through March. All other customer classifications use monthly water meter consumption totals. Wastewater customers who are not Missoula Water customers or are customers but do not have a meter, will be billed at a flat rate. The Mixed Use with Food Service is a new classification.
Sewer Use Fees were revised previously in 2011 and 2015.
