Septic Systems

Spokane Regional Health District’s (SRHD) Liquid Waste program works with homeowners, businesses and contractors to ensure that on-site sewage disposal (septic) systems are properly designed and installed. This includes confirming compliance with regulations through permitting and inspections of on-site sewage systems for single-family homes, small businesses, and apartment buildings that use less than 3,500 gallons of water per day.

Proper septic system design and installation helps prevent public exposure to sewage and protects groundwater and surface waters in the region. If untreated sewage enters the groundwater, area wells could become contaminated, creating a health hazard with the potential to cause many human diseases. Similarly, sewage allowed to contaminate nearby streams or water bodies can harm aquatic life and jeopardize recreational swimming areas.

The Liquid Waste program permits and inspects on-site sewage systems using less than 3,500 gallons of water per day. Washington State Department of Health and Washington Department of Ecology enforce regulations for larger sewage systems and those systems that treat industrial wastewater.
