Back River Wastewater Treatment Plant, Baltimore, Md.

• Digester gas-to-energy plant for Back River Wastewater Treatment Plant
• Plant treats 180 million gallons of sewage for 1.3 million residents daily
• Collects digester gas, cleans gas to remove harmful elements, finalizes transfer and sale of gas into the natural gas pipeline
• Project implemented in 1983 and operated for over ten years

Washington [D.C.] Suburban Sanitary Commission (WSSC),
Laurel, Md.

• Allows sludge to be combusted in multiple hearth incinerator with little to no additional natural gas by using Btu's found in sludge instead of natural gas as the combustion fuel
• Implemented under $10 million ESPC contract of which $5.56 million in capital was invested in the incinerator project
• Annually more than $700,000 saved in avoided costs
• Additional savings realized through an innovative 15 year electric supply arrangement that includes a 10 year direct purchase wind energy for 33% of WSSC's electric needs.
• Part of a long-term project that includes two $10 million ESPC projects and an integrated electric procurement strategy that reduces energy and operational costs while increasing efficiencies to meet further demand

Hamilton-Wentworth Water & Sewage Treatment Facility,
Hamilton, Ont., Canada

• Redistributes digester gas for use in facility’s stand-by generator and for heating and dehumidification
• Replaces natural gas previously used to fire central steam plant
• Produces significant energy cost savings and reduction of greenhouse gas emissions
• Further savings realized by combining ESPC contract work with other energy conservation measures
