Our water comes from the Spokane Valley-Rathdrum Prairie Aquifer. The aquifer serves as the sole source of water for most of the people in Spokane County in Washington and in Kootenai County in Idaho. Discovered in 1895, this Aquifer has become one of the most important resources in the region, supplying drinking water to more than 500,000 people. The Aquifer has been studied in considerable detail since 1977, and the results of these investigations have produced programs and regulations designed to ensure this aquifer will remain a valued and protected resource for future generations.
