The City has initiated Phase II of a multi-phase water system maintenance project to replace valve components on the water transmission main that connects the Ten-Mile Water Treatment Plant to the City of Helena’s reservoirs. Phase II of the Crosstown Connector Valve Replacement Project will include work at 13 locations on the west side of Helena between Woolston Reservoir and Malben Reservoir. The project will require limiting the water supply from the Ten Mile Water Treatment Plant and supplementing with water from the Missouri River Treatment Plant until the construction is complete. Whenever the Missouri River plant is turned on, it is common that some residents experience slight discoloration or odor in their water. The changes should not be of concern and are typically resolved quickly.
The project has been planned to minimize disruptions to the public; however residents may encounter temporary street closures and traffic control measures, and some properties may require temporary water service to be piped in from elsewhere in the system. City staff and the contractor team will be in contact with any property owners impacted by the work.
The project will be completed in four phases: Phase 1 (completed Fall 2025), Phase 2 & 3 (tentatively scheduled for Fall 2026), and Phase 4 (tentatively scheduled for Spring 2027). The project is funded by the Drinking Water State Revolving Fund.
