As our magnificent region continues to grow, so do the demands for clean, safe reliable drinking water. Cascade's mission is to provide water supply to meet current and future needs of our members in a cost-effective and environmentally responsible manner through partnerships, conservation, acquiring, constructing and managing water supply infrastructure and fostering regional water planning. Cascade is a non-profit corporation comprised of eight municipalities (five cites and three water and sewer districts) in the Puget Sound region that joined together to provide safe, clean, reliable water supply to its almost 400,000 residences and more than 22,000 businesses.
