HDR Participates in and Helps Organize Atlantic Treatment Plant Ribbon-Cutting Ceremony

(October 11, 2013) - The Hampton Roads Sanitation District (HSRD), Virginia Beach, Va., recently hosted a ribbon-cutting ceremony to dedicate and open its combined heat and power system (CHP). HDR served as the primary engineer.

Glen Ellmers, the HDR Water & Natural Resources business group East Region director, was one of the speakers at the ribbon cutting ceremony in Virginia Beach. The program included a tour of both the CHP system and full Atlantic Treatment Plant.

After Phase I of the Atlantic Treatment Plant's expansion was completed in 2010, the sanitation district found that the newly installed two-phase digestion design was producing enough digester gas to generate 1.6 megawatts of renewable electric power for the plant.

That was enough power to meet nearly 50 percent of the plant's total power demand and also provide over 50 billion British thermal units (BTUs) per year of recovered heat for digester and building space heating.

Consequently, the sanitation district retained HDR to design the new combined heat and power system.

Now in service, the system reduces the plant's carbon footprint for purchased power by almost 9,000 tons of carbon dioxide each year and saves nearly $650,000 from HRSD's annual electric bill.
