Septic & Wastewater

Nearly 1 in 4 U.S. households depend on an individual on-site sewage system or a small community cluster system to treat their wastewater. If properly built and maintained, decentralized wastewater treatment systems have many benefits, including:

  • Allowing for development in outlying communities and properties
  • Protecting groundwater, lakes, and the Puget Sound from contamination
  • Reducing exposure to untreated sewage
