5. Where does my wastewater go?

Wastewater, or sewage, flows to different areas depending on the facilities you have on your property. Wastewater that flows from properties connected to the regional wastewater sewage system is sent to the King County South Treatment Plant in Renton where it undergoes several treatment processes before being released through an outfall pipe into Puget Sound. Wastewater that flows from properties that utilize septic systems is recycled on the same property where it originates. In a septic system that is properly maintained, the waste is purified and returned to the groundwater. It is essential to maintain your septic system on a regular basis for maximum operational benefits. For septic system resources and information, visit King County Public Health or the Washington State Department of Health.
