Located in South Arlington, the Water Pollution Control Plant (WPCP) is a facility that treats 30 million gallons of wastewater each day from County residences and business, with nearly 20 percent of the plant's flow coming from neighboring localities such as Alexandria, Fairfax and Falls Church. The plant's mission is to safely and economically process wastewater and hazardous waste materials to protect our environment, especially Four Mile Run, the Potomac River and the Chesapeake Bay.
Due to a growing population in both Arlington's residential and business communities, there has been an added strain in recent years on the WPCP's aging facility that was originally built in the 1930s.
A major $568 million upgrade of the WPCP is nearly complete to meet new federal and state regulations.
