Over 30% of Oregonians dispose of their wastewater through septic systems. Properly functioning septic systems treat sewage to prevent ground and surface water pollution. It is up to the homeowner to be informed and protect their community and environment. A failing system or an illegally installed system can jeopardize that protection and the value of the home.
