HERSHEY, PA — Environmental engineering and construction firm Brown and Caldwell has been selected by the Derry Township Municipal Authority (DTMA) to design energy efficiency improvements at its Clearwater Road Wastewater Treatment Facility (WWTF).
The facility upgrades are considered key to expanding capacity and increasing energy efficiency, thereby evolving the 5.02 million gallons per day WWTF into a highly sustainable operation.
Once the improvements are complete, the WWTF will increase biogas power generation from 280 to 1,600 kilowatts per hour, significantly reducing the facility’s carbon footprint.
The team, led by Brown and Caldwell, includes RK&K, who will provide electrical and instrumentation expertise, and Bassett Engineering, who will assist with permitting, site design, and stormwater control.
The design phase of the project will run through May 2020, with construction scheduled to begin by fall 2020.
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, states a release.
Brown and Caldwell will assist DTMA with the procurement of the engines through COSTARS, the Commonwealth of Pennsylvania’s cooperative purchasing program.
Other WWTF improvements will 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, adds the release.
