Water Service Line Survey

Chester Water Authority is undertaking a water service line study in accordance with the EPA Lead and Copper Rule Revisions. Please note that CWA has NO LEAD WATER MAINS. However, some houses, especially older ones, may have lead service lines that run from the water main into the house. CWA wants to identify and map where those lead service lines exist in the system so that they can be addressed. As part of this study, we are looking to verify the material of water service lines in your area. You can help us by completing the survey to tell us about the material of your water service line.

Chester Water Authority is a non-profit municipal authority that serves clean, affordable, award-winning water to 34 municipalities in western Delaware County and southern Chester County, Pennsylvania.

CWA is the steward of 2000+ acres of watershed that surround the Octoraro Reservoir. This includes 100 acres that is set aside with the PA Game Commission to allow for public turkey hunting. This land is home to many animals, and we wanted to bring some of that wildlife to you! You will see deer, raccoons, lots of birds, even cats on our camera installation!
