The Liquid Waste (on-site sewage/septic) program at Spokane Regional Health District exists to ensure that on-site sewage disposal systems are properly designed and installed to prevent public exposure to sewage, and to protect ground water and surface waters in the region.
The work of this program is important to maintain the safety and quality of drinking water. Should untreated effluent enter the groundwater, area wells may become contaminated, creating a health hazard with the potential to cause many human diseases. In addition, should this sewage reach nearby streams or water bodies, aquatic life and recreational swimming areas may be jeopardized.
The program is funded primarily with application fees and permit fees. The Liquid Waste program works with outside agencies like Washington State Department of Health, Washington State Department of Ecology, and local building and planning departments to carry out its mission. Additionally, Washington State Department of Health and Washington Department of Ecology enforce regulations for larger sewage systems and those systems that treat industrial wastewater.
