/Pennsylvania (CEC/PA) presented the 2002 Grand Conceptor Award for Engineering Excellence to Buchart-Horn, Inc./BASCO Associates and the Derry Township Municipal Authority for design improvements to the Township's Clearwater Road Wastewater Treatment Plant.
The centerpiece of the project is a 100-foot tall egg-shaped anaerobic digester that consumes considerably more biosolids than conventional digesters. Utilizing the latest European technology, the egg-shaped digester is the largest of its kind in Pennsylvania.
The unit also captures methane gas that is currently used to heat plant processes and several structures on the site. Collected methane gas fires a boiler that heats sludge inside the egg. The gas also heats the boiler building, an auxiliary structure and the headworks building.
Additional improvements include an ultraviolet (UV) disinfection system that eliminates the need for chlorine at the plant. Together, the upgrades are projected to trim operation costs by more than $250,000 annually for this facility that connects to 6,600 locations servicing 20,000 people.
The project also received national recognition through the American Council of Engineering Companies (ACEC) at an awards ceremony in Washington, DC. where Wayne Shutz, Derry Township's Assistant Manager and Brian S. Funkhouser, PE, a Buchart-Horn, Inc., Regional Vice President and Director of the firm's Environmental Engineering group, accepted the national merit award in February, 2002.
