Septic Links


For decades, the health of South Puget Sound waters has been a critical focus of the State of Washington’s Department of Ecology. It is remarkable how clear these waters have been maintained due to the efforts of our counties to regulate residential septic systems. Thurston County has been a mentor to other county’s efforts to provide the necessary guidelines to keep our water free of pollutants but it is up to the individual home owner to understand how they can do their part.
