Wastewater plant grant expected to save energy, money

10:00 am | July 1, 2013

A $176,000 Clean Tennessee Energy Grant from the Tennessee Department of Environment and Conservation will allow an aging and inefficient conventional treatment system at the Elizabethton Wastewater Plant to be decommissioned.

That, in turn, is expected to cut energy costs at the plant.

Gov. Bill Haslam presented Mayor Curt Alexander with a $176,000 grant for the city’s wastewater treatment plant.

Gov. Bill Haslam presented the grant to Elizabethton Mayor Curt Alexander during the dedication ceremony Friday for the Interpretive Exhibit at Sycamore Shoals State Historic Area.

The grant provides funding for operational improvements to the city’s wastewater treatment plant to generate energy savings. The funding will be used to install oxidation ditch equipment into an existing unused basin, allowing an aging and inefficient conventional treatment system to be decommissioned.

The proposed project will lower the plant’s monthly aeration power consumption from 76,800 kilowatt hours to 59,000 kilowatt hours, resulting in a monthly energy consumption savings of approximately 17,800 kilowatt hours.

This project will save $20,826 in aeration power costs in 2013 and annual emissions reductions will be 231 pounds of nitrogen oxide, 728 pounds of sulfur dioxide, and 306,951 pounds of carbon dioxide.

“I am proud to see this commitment at the local level to implement innovative technology and improve efficiency,” Haslam said. “The Elizabethton project announced today highlights local efforts across the state to save taxpayers’ dollars as we continue our work to make Tennessee the best place to live, work and raise a family.”
