Water Service Line Material Map and Information

In accordance with the EPA Lead and Copper Rule Revisions, Chester Water Authority is required to identify all water service line materials in our system. The Water Service line is the pipe that connects your home or business to the large water main in the street. CWA is required to notify all customers if any portion of the water service line is Lead, Galvanized Requiring Replacement, or Unknown. As a customer you may receive a letter in the mail stating “CONSUMER NOTIFICATION OF A LEAD STATUS UNKNOWN SERVICE LINE”. This notification has been sent to all customers where CWA needs to identify the materials on the customer-owned portion of the service line. Please view our Water Service line Material Info for more information on the status of your service line.

BE ADVISED

PA Department of Environmental Protection Drought Warning Notification

Conserving water is always a good idea, but during a drought it is a necessity. Pennsylvania uses a three-stage drought-operating plan. It begins with a Drought Watch requesting a voluntary 5% reduction of water use, and then progresses to a Drought Warning requesting a voluntary 10% reduction of water use. The final stage is a Drought Emergency which imposes mandatory restrictions on nonessential water use.

Areas served by Chester Water Authority (CWA) are presently under a Drought Warning declared by the Pennsylvania Department of Environmental Protection on February 18, 2026.
