FPU recognized for wastewater's energy efficiency

Fayetteville Public Utilities has been recognized for its successful participation in the Tennessee Water and Wastewater Energy Efficiency Partnership Program in a ceremony held in Nashville by the Environmental Protection Agency (EPA) and the Tennessee Department of Environment and Conservation (TDEC).

FPU was among seven drinking water and wastewater utilities across the state recognized for their efforts to reduce energy consumption at their respective facilities.

According to the EPA, improvements already made at four of the seven utilities are collectively saving 3,300,000 kilowatt hours, $260,000 and over 3,200 tons of annual carbon dioxide emissions. With the additional improvements underway or planned at the utilities, the initiative is expected to save over 7 million kilowatts per year and reduce carbon dioxide emissions by 6,696 tons - equivalent to removing 1,190 cars from the road or powering 739 homes for a year.

Each of the utilities participated in workshops and conducted energy assessments to determine how best to reduce energy use at their plants.

FPU’s Wastewater Treatment Plant is projected to reduce the 2012 base load of electric consumption by 27 percent which equals a $34,000 savings to the facility’s operation cost.

 FPU was able to operate the plant’s digesters at reduced aeration levels while closely monitoring plant performance and biosolids quality. Other energy-saving steps have been taken since 2010 that include the aeration of our oxidation ditches and replacing 22-year-old gearboxes and motors to optimize plant performance.

“FPU is very glad to be recognized and to have the opportunity to participate in the program to see where additional savings could be made,” said Britt Dye, FPU’s CEO and general manager.

“EPA applauds these utilities in Tennessee for their leadership in reducing energy use, which is expected to save costs and yield substantial benefits across the state and Southeastern region,” said EPA Regional Administrator Gwen Keyes Fleming.
