Operational Savings from Energy Performance Contract Expected to Cover Cost of Improvements to Water Reclamation Plant

Frederick Winchester Service Authority’s (FWSA) Opequon Water Reclamation Facility helps to preserve water quality in Chesapeake Bay, meeting requirements for nitrogen and phosphorus removal. After a recent upgrade to reach new, more stringent nutrient limits of 4mg/L TN and 0.3 mg/L TP, the utility faced increased operating costs in addition to the significant additional debt service. Black & Veatch put together an Energy Savings Performance Contract (ESPC) to help guide the facility through its changes. 

The $45 million performance contract is for the design and construction of comprehensive energy efficiency and infrastructure improvements at the 12.6 million gallons per day (mgd) reclamation facility. The improvements will reduce operating costs enough to cover the debt service on the project, pay for other needed plant improvements, and defray costs for the previous upgrade.
