Septic System Assistance

There are over 4,000 septic systems upstream of the Eugene Water & Electric Board (EWEB) drinking water intake in the McKenzie Watershed. Properly maintained septic systems and drainfields can greatly reduce the risk of contamination in the river and save homeowners money over time. EWEB has a financial assistance program available to homeowners upstream of the drinking water intake at Hayden Bridge.
