WAWA Convenience Store

WAWA is a convenience store chain with stores in the mid Atlantic states. Many locations are situated within the Chesapeake Bay watershed. Due to the degraded water quality of the Bay, the EPA has placed great emphasis on reducing nutrient loading from the watershed. Many convenience stores are located on routes not served by centralized sewers.

Keystone Engineering Group, Inc. of Frazer, PA specified a Walden SBR plant to treat the flows from a WAWA located in Bel Air, MD because the existing treatment plant was unable to attain the required effluent quality required. Johnston Construction Company from Dover, PA installed the system and the system is being operated by Singh Operational Services, Inc, a contract operation and maintenance firm for both water and wastewater systems
