Seattle Public Utilities provides water for approximately 1.4 million people living in the Greater Seattle, Washington metropolitan area. To help Seattle and the surrounding cities keep thriving and growing, Seattle Public Utilities sources water from the Cedar and the Tolt watersheds, both of which contain water so pure, it doesn't need to be filtered (treated only).
