Clean, Reliable Water.
Driven by the Basin, Built for the Future.

The W20 Project

The W20 Project is a locally led water infrastructure initiative designed to deliver region-wide benefits for Grant County and the greater Columbia Basin. Developed through collaboration among local stakeholders, the project strengthens water reliability, improves water quality, and enhances the long-term performance of the Columbia Basin Project.

By investing in smart, integrated infrastructure, W20 creates a rare set of win-wins that serve municipal, industrial, environmental, and agricultural needs simultaneously – for generations to come.
