Frederick-Winchester Service Authority

We partnered with the Frederick Winchester Service Authority on an energy savings performance contract (ESPC) featuring innovative upgrades like an anaerobic digester and dewatering facility for their Opequon Water Reclamation Plant. Our solutions generated renewable energy, created new revenue streams, reduced hauling costs, and enabled phosphorus recovery while supporting the plant’s critical Chesapeake Bay nutrient removal requirements.

"ESG brought to the table levels of expertise that we could not really expect one general contractor to come up with."

-Dick Helm, FWSA Executive Director

  • The anaerobic digester facility generates up to 848 kilowatts of renewable electricity on-site under average loading conditions.
  • The dewatering process cuts the amount of biosolids hauled to landfills for disposal by approximately 50 percent.
  • The operational facility can take over 125,000 gallons per day of high-strength waste and generates $1.25-$1.5 million per year in revenue potential.
  • The upgrades also enable the harvesting of phosphorus, an essential and rare element for fertilizers and crop production.
