The City of Kirkland provides drinking water purchased from Seattle Public Utilities (SPU) through Cascade Water Alliance
, an association of regional water districts and cities. The water typically comes from the South Fork Tolt River Watershed in the Cascade Mountains. SPU performs most of the sampling and treatment for Kirkland’s drinking water; however, the Kirkland Water Division operates and maintains the City’s water infrastructure. For more information about your drinking water, please see the Annual Water Quality Report
The Cascade Water Alliance was created to provide water supply to meet current and future needs in a cost effective and environmentally sensitive manner by purchasing wholesale water from other suppliers; coordinating conservation and supply management; acquiring, constructing and managing water supply infrastructure and fostering regional water planning to provide water for people, fish and fun.
Cascade is working to address current and future water supply efficiency needs through conservation programs. Today the Cascade member communities serve over 370,000 residents and 22,000 businesses. For more information, visit cascadewater.org.
