COATESVILLE, PA — Pennsylvania American Water imposed mandatory conservation measures Sept. 6 on about 23,000 customer connections in its Coatesville water system after weather-related changes in local water sources increased treatment demands and temporarily reduced plant capacity.
Customers must limit water use to essential purposes and target a 10% to 15% reduction in consumption until the utility lifts the order.
The restrictions extend across portions of Chester and Lancaster counties. In Chester County, they affect Coatesville, Atglen, Parkesburg and South Coatesville, along with Caln, East Fallowfield, Highland, Valley, West Brandywine and West Sadsbury townships.
Lancaster County communities covered by the order are Christiana and Quarryville and Bart, Colerain, Eden and Sadsbury townships.
Pennsylvania American Water attributed the restrictions to recent weather-related changes affecting local water sources. Those conditions increased the amount of treatment required at the plant, placing additional demand on filtration systems and temporarily reducing treatment capacity, according to the utility.
The conservation order is not a boil-water advisory. Pennsylvania American Water did not report that the water is unsafe to drink in the information provided with the order.
The restrictions affect households and businesses served by the Coatesville system and are intended to reduce demand while treatment capacity is constrained.
Pennsylvania American Water is notifying affected customers through its automated emergency notification system. The company said it will provide updates as needed and notify customers when the mandatory restrictions are lifted.
