The Town of Trappe Wastewater Treatment Plant

Trappe Wastewater Treatment Plant lab, office, and equipment building 4110 Hennissee Lane

Trappe's wastewater plant, originally constructed around 1961, consisted of a series of facultative and partially aerated lagoons or ponds. April 2002 saw the lagoon system replaced by a new Biolac extended aeration activated sludge treatment plant with continuous backwash sand filtration. The treated wastewater is disinfected with chlorine, chemically dechlorinated, and mixed with fresh air before being dischared to the receiving stream. Our new plant is designed to discharge extreamly low levels of phosphorus and ammonia nitrogen. We are currently treating about 90,000 gallons of wastewater per day. Our plant has a rated capacity 200,000 gallons perday.

Our old lagoons will be maintained as required emergency emergency holding areas and will likely continue to be visited by various species of water fowl. To inquire about the operation of the water or sewer system, please contact Steve Callahan and Jessica Banzet at the wastewater treatment plant lab. Phone: (410) 476-5297, or click the mail box to send e-mail. A varity of water fowl enjoy visiting our wastewater ponds.
