Our History


CWA was created for a single purpose – to supply pure water to homes and businesses.  For over 137 years, since its origin as the South Ward Water Works, CWA has maintained the highest standards of water quality and customer service.


In 1939, the Chester Municipal Authority was incorporated with a five-member Board of Directors, which purchased the South Ward utility. The Municipal Authority was a vibrant, expanding operation that built the Octoraro Reservoir, which is located in Lancaster County. A water treatment plant and a 45-mile-long transmission pipeline connected the new water supply to our customers in the City of Chester and surrounding areas. Throughout the 1950s and ’60s, the Authority increased the treatment capacity of the plant and the storage capacity of the distribution system.


In 1965, the name of the Municipal Authority was changed to Chester Water Authority, and improvements continued.

Through our on-going capital projects and commitment to pro-active maintenance, CWA continues to deliver quality drinking water to the community. Recent projects include the following:


Significantly upgrading the Village Green West distribution system
