Water Quality

Cascade Members are the Source of Quality

Cascade is all about drinking water – for today and tomorrow – and that means safe and clean water. Cascade members monitor and treat their water and are Cascade’s source of water quality. Each member prepares and issues a water quality report annually:

Cascade gets its water from the Seattle system, which is of the highest quality and is tested frequently. As new sources come on line, Cascade will treat water to meet or exceed all federal, state, and local quality standards just as our partners Seattle and Tacoma’s Public Utilities do today. Extensive monitoring will be conducted prior to designing and constructing a state of the art treatment facility at Lake Tapps.
