The Frederick-Winchester Service Authority (FWSA) is completing a $45 million energy performance contract with Energy Systems Group (ESG), a leading energy services provider, which includes the design and construction of comprehensive energy efficiency and infrastructure improvements at the Opequon Water Reclamation Facility. This project will achieve operational savings that not only cover the cost of the project, but create a revenue stream for FWSA, stabilizing rates for its customers and promoting existing and future economic development in the Winchester, Frederick-County area.
The centerpiece of the FWSA project is the construction of a Green Energy Facility, which will process municipal sludge and high-strength organic waste, from food processors in the Shenandoah Valley, to produce methane gas, a renewable fuel, through the process of anaerobic co-digestion. This methane gas will be utilized to generate up to 848 kilowatts of electricity that, at start–up, will meet more than 50 percent of the treatment plant’s electrical needs. This facility also includes a new sludge dewatering process that reduces the use of chemicals and significantly reduces the amount of biosolids hauled to the Regional Landfill for final disposal, by approximately 50 to 60 percent.
The Green Energy Facility will also harvest phosphorus from the wastewater stream, a rare element that is an essential ingredient for fertilizer and crop production. The fully upgraded facility also includes a new food waste receiving station, and other facility improvements such as emergency electrical generation, turbo blowers and fine bubble diffusers for process treatment aeration, and lighting and mechanical system improvements.
The facility is expected to come online in 2016.
