Raw Water Transmission Project for the Water Treatment Plant
The Town of Johnstown will be installing approximately 11 miles of 24"-48" diameter raw water transmission mainline to increase the Town's current raw water supply to the Water Treatment Plant. This project complements the Water Treatment Plant Expansion project, which will expand the WTP's treatment capacity by nearly double to 12 million gallons per day with the ultimate build out capacity of the plant being 21 million gallons per day.
Project Timeline & Key Milestones
- The project is currently in the design phase. The Town anticipates the design to extend into 2024 with land acquisition following the design
- Construction schedule: TBD

Project Updates & Impacts
Town Staff received a conceptual design for the project in July. The design engineer is continuing to work with Town Staff to set the final alignment from Lone Tree to the Water Treatment Plant. The primary focus is between Lone Tree Reservoir and Highway 287, which has multiple constraints. The Town and the design engineer have been coordinating with property owners, Home Supply Ditch Company, the TPC golf course, and utility providers to coordinate the design. Meetings have been held with neighboring jurisdictions to determine their review and permitting processes.
- To increase raw water capacity to the Water Treatment Plant.
- Reliable raw water supply for Water Treatment Plant's future increased capacity
- Improved raw water reliability to the Water Treatment Plan
