Montgomery County, PA Water: What Homeowners Should Know
Learn what public reports say about Montgomery County, PA drinking water, water mains, private wells, and sewer planning—and how to check your own water.
Montgomery County does not have one water system for every home. Some homes get water from a public utility. Others use a private well. Sewer service also changes by town. That means a report about one water provider may not describe the tap water at another home nearby.
Where does Montgomery County tap water come from?
Start by checking the name on your water bill. If you have public water, look up that provider’s latest water quality report. It is also called a Consumer Confidence Report. It tells you where the water comes from, what the provider tested, and whether the reported results met drinking-water rules.
If your home uses a private well, you are responsible for testing it. The CDC says private well owners should test once a year for certain germs and chemicals, including bacteria, nitrate, and pH. Test sooner after a flood, a repair, or a change in the water’s color, taste, or smell. Read the CDC’s well testing advice (opens in a new tab).
What do public records say about water and sewer pipes?
Montgomery County’s planning page says local towns and the Pennsylvania Department of Environmental Protection oversee the design, permits, operation, and upkeep of water and sewer systems. The county helps review plans. Its public water and sewer facility reports include a 2018 water report and a 2015 sewer report. Those reports are useful history, but they are not a live count of every pipe today. See Montgomery County’s water and sewer planning records (opens in a new tab).
Some water main work is planned for certain towns. A state project list names water main replacement work in Collegeville, Lower Merion, and Perkiomen Township, among other nearby places. The listed pipes were picked because they were near the end of their useful life, had a history of leaks, or were in poor shape. This does not mean every water main in Montgomery County is old or failing. See Pennsylvania’s water project list (opens in a new tab).
What should homeowners do?
For public water, use the report from your own provider. For a private well, use a certified lab and keep a copy of each test. If you see a water main project nearby, ask the utility what work is planned and whether service lines to homes are included.
