Spokane Aquifer Joint Board Mission

The Spokane Aquifer Joint Board (SAJB) is comprised of twenty-one water purveyors throughout the Spokane area dedicated to providing safe, clean drinking water to your homes, offices and industries every day. Collectively we operate 122 wells, supplying drinking water to more than 500,000 people in the Spokane area. Each purveyor draws water from the same source – the SPOKANE VALLEY – RATHDRUM PRAIRIE AQUIFER.

Our collective priority is to protect the public water supply by coordinating efforts, performing and sponsoring studies and investigations, and providing a discussion forum with respect to developing and implementing public water supply programs such as:

  • wellhead protection,
  • conservation, and
  • protection of associated Water Rights.

In our efforts to protect the Aquifer and the Wellheads through which your drinking water is drawn, we formed the SAJB and completed a lengthy Wellhead Protection Plan. We are now implementing our Wellhead Protection Program, working within four distinct areas of emphasis to increase citizen participation in protecting this irreplaceable resource: education and awareness, household contaminant disposal, proactive business assistance and potential contaminant source inventory.

The Spokane Aquifer Joint Board was formed on April 25, 1995, under RCW 39.34, known as the Washington Interlocal Cooperation Act. The Agreement For Formation is provided, however, for security purposes, the signature pages are not included.
