Sewer Planning & Design

The Sewer Planning & Design section oversees and regulates the installation of all sewers which connect or discharge to the County's Regional Sewer System. The ongoing goal of the sewer program is the prevention and elimination of septic tanks above the Spokane Valley-Rathdrum Prairie Aquifer, Spokane's sole source potable water supply.
