Areas Served

The Delaware County Water Quality Control Authority (DELCORA) is a municipal authority with a long history of environmental success in the operation of wastewater facilities.

Since its establishment in 1970, with the acquisition and upgrade of the City of Chester’s wastewater treatment plant to become DELCORA’s Western Regional Treatment Plant (WRTP), the authority has grown through a prudent approach to the construction, acquisition and management of wastewater collection, conveyance and treatment systems.

Today, the authority owns, operates and maintains collection systems that serve approximately a half million people in the Greater Philadelphia area including 46 municipalities in Delaware and Chester Counties.

DELCORA’s direct customers include residents in: Chester City, Chester Township, Upland, Parkside, Trainer, Marcus Hook, Rose Valley, The Preserve at Chadds Ford (Pocopson), and Riverside (Pocopson).

Delaware County residents and businesses generate millions of gallons of wastewater every day. This wastewater must be collected, conveyed, and treated in a safe, effective way that prevents the contamination of our community’s streams, rivers, and general water supply. DELCORA, the Delaware County Regional Water Quality Control Authority, has been providing this vital function to our communities for over four decades. Serving as a municipal authority, DELCORA, owns, operates, and maintains these wastewater facilities that serve approximately half a million people, including 46 municipalities in Delaware and Chester Counties.  DELCORA collects and conveys an average daily wastewater flow of approximately 60 million gallons per day (mgd) with an instantaneous peak flow of approximately 200 mgd.  As a result, the citizens of our region enjoy clean, healthy water.

Because of our carefully planned investments, we now have an extensive infrastructure throughout Delaware County. This well-maintained system enables us to meet, and in many cases, exceed all of the water discharge quality mandates set by the PA Department of Environmental Protection and the US Environmental Protection Agency.

Everyone associated with DELCORA recognizes the importance of good stewardship of both the environment and the economic resources of our community. We proactively utilize the latest, most effective methods for treating wastewater and solids. We also emphasize keeping our infrastructure up to date and in peak operating condition.

Thanks to DELCORA, the Delaware River and its tributaries throughout our communities are cleaner and healthier. Best of all, we have the capacity and commitment to effectively accommodate the wastewater demands of our area’s expanding population now, and in the future.
