Sewer Information

Every year the snow melts, the rain falls, and the water that runs off your yard carries fertilizers, herbicides, and pesticides into our creeks, streams, and rivers. These pollutants can harm fish, wildlife, and vegetation and even compromise the rivers that are our major source of drinking water. Learn how you can do your part to protect your loved ones drinking water in this Homeowners Guide to Stormwater BMP Maintenance and this Homeowner’s Guide to Protecting Our Watershed.

Three Rivers Wet Weather lets you see where you are really putting your fertilizer and what you can do to help.


Ben Avon is required through the Federal Clean Water Act (CWA) to manage a Municipal Separate Storm Sewer Systems (MS4s).
