Cascade is all about water – for today and tomorrow – and that means safe and clean water. Cascade's water is of the highest quality, and 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. Actual water quality and regulations applicable at the time Cascade builds the plant will determine the exact type and level of treatment required. Ongoing water quality testing and monitoring will be done. Across the country, many surface supply sources similar to Lake Tapps are used for recreation, with treatment technology making these sources extremely safe for drinking water as well.
