Colville Reservoir 2 Replacement
Replacing aging water infrastructure with a modern reservoir system designed to improve reliability, emergency response, and long-term resiliency for the City of Colville.
PROJECT OVERVIEW
Welch Comer partnered with the City of Colville to replace Reservoir 2, a critical component of the City’s water system. After evaluating multiple alternatives, the team determined that constructing a new reservoir at the City’s existing wellfield would provide the most reliable long-term solution.
