Water Projects

Missoula Water has implemented a water main replacement program to reduce leakage and replace aging water mains. The projects shown here are critical to achieving that goal. In addition to water main projects, the City completes other water system infrastructure projects the keep the system working at an efficient and optimal level of service for our customers.

3rd Street Water Main Replacement

Description: Replacing 1,870 lineal feet of 6-inch Kalamein water main pipe between Orange St and Oak St that was originally installed in 1914. Missoula Water is coordinating this work with the Storm Water Utility and Street Maintenance Division to improve storm water infrastructure, install Americans with Disabilities Act (ADA) ramps, and mill and overlay the full width of 3rd St. Water services will be replaced from the water main to the curb box.

  • Work will start at Orange St. and move west. Portions of 3rd St. will be closed during construction, usually one or two blocks at a time.
  • Please see detour maps link below for detour routes and tentative construction schedule dates.
  • Streets will reopen to local traffic once water main is installed. Please drive slowly and watch for potentially rough, patched areas.
  • After main installation, crews will begin replacing services lines to individual buildings. The new service lines run from the new main to the property owner’s curb box. 
  • ADA ramp installation work may be moving forward at the same time but will not impact traffic or construction work.
  • All of 3rd St. from Orange St. to Ash St. will be repaved curb to curb once all water main and service line work is done.

Project Dates:  Scheduled to begin Monday, April 27, 2020, with completion anticipated to be in late July. These dates are subject to change due to weather and other unforeseen circumstances.
