To ensure getting a permit is as simple as possible, the health district developed this process.

Below is a higher-level description of this process.

New on-site sewage systems and systems located over the Spokane/Rathdrum Aquifer are tracked and issued a renewable three-year permit by the health district.

On-site sewage system inspection and maintenance is required, prior to permit renewal.

Systems designed for single-family homes, small businesses, and apartment buildings (systems less than 3,500 gallons per day) are:

  • reviewed for compliance with regulations
  • permitted
  • inspected after installation

Fees vary based on the size and type of system (view current Spokane Regional Health District Fee Schedule)
