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).
