Where does Issaquah's water come from? A major portion of Issaquah's water system comes from groundwater served by four wells - two in the northeast section of Issaquah and two in the northwest section. The wells are deep: two are 100 feet deep, one is 200 feet deep and one is 400 feet deep. Additionally,  the Cascade Water Alliance (CWA) continues to provide water to the Issaquah Highlands and Talus urban villages, as well as the Montreux and Lakemont areas. Cascade is a municipal corporation comprised of eight municipalities and water districts that joined together in 1999 to provide water supply for current and future needs.
