The Chester Water Authority (CWA) is pleased to announce that the boil water advisory issued on March 26, 2026, following a water main break in Upper Chichester Township, has been lifted. The issue has been fully resolved, and it is no longer necessary for customers to boil their water before use.

We are pleased to report that the problem has been corrected and that it is no longer necessary to boil your water.

Two consecutive days of “clean” test results are required before DEP will allow the advisory to be lifted. (The process takes 18-24 hours for test results to come back from the laboratory, so final lab results to lift an advisory can take several days after the event.)

The water distribution system has returned to standard operating conditions, and customers should be experiencing normal water pressure in their homes.

Great news reporting from the Chester Water Authority (CWA). Crews have successfully isolated the major water main break located within an active construction zone along Route 322 near Cherry Tree Road in Upper Chichester Township. The incident, which began on March 26, 2026, resulted in service disruptions and reduced water pressure across the system. As of 4:20 p.m., the source of uncontrolled water loss has been contained, allowing the system to begin stabilizing and recovering.

Significant progress has been made in installing the necessary components to isolate the leaking sections of the damaged main. To support and accelerate repairs, two specialty contractors are on site assisting CWA crews.

The Chester Water Authority (CWA) has confirmed that there was a water main break located within an active construction zone along Route 322 near Cherry Tree Road in Upper Chichester Township. CWA is currently investigating the cause of the break and will report its findings to ratepayers as soon as the review is complete.

This is a message from Chester Water Authority.  Those in the following areas of Upper Chichester, Lower Chichester, Marcus Hook, and Twin Oaks DO NOT DRINK THE WATER WITHOUT BOILING IT FIRST.
