“Increasing the production and beneficial use of anaerobic digester biogas as our fuel source to provide power and heat is significantly more efficient and environmentally sustainable than using electrical power from the grid or fossil fuels.

Other improvements include a conveyance system to transport gas throughout the facility, sludge blending tank enhancements to maximize energy recovery via biogas generation, and secondary digester modifications for future conversion to a primary digester. Brown and Caldwell will assist DTMA with the procurement of the engines through COSTARS, the Commonwealth of Pennsylvania’s cooperative purchasing program. After pairing with a new gas conditioning system for high-quality fuel production, the CHP facility will integrate into the WWTF’s existing electrical and heating system to provide electricity and heat throughout. Under DTMA’s $15 million energy enhancement program at the WWTF, Brown and Caldwell will lead the design of a combined heat and power (CHP) facility capable of burning biogas that will power two generator engines. Facility upgrades are considered key to expanding capacity and increasing energy efficiency, thus evolving the 5.02 million gallons per day WWTF into a highly sustainable operation.

Brown and Caldwell, a leading environmental engineering and construction firm, has been selected by the Derry Township Municipal Authority (DTMA) to design energy efficiency improvements at its Clearwater Road Wastewater Treatment Facility (WWTF).Īlready accepting organic waste from third-party carriers, the Authority is developing long-range plans to maximize the capability to receive additional organic wastes.
