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