Tupelo Bayou Wastewater Treatment Plant (TBWWTP) on Lollie Road in southwest Conway will begin operating in July 2014. PC Construction, Inc. began construction of the plant in May 2012.
Ultimately, the plant will be able to process 32 million gallons a day (MGD). The initial phase features two parallel 8 MGD liquid trains for a total capacity of 16 MGD. Additional capacity increases can be constructed in 8 MGD increments, with a 24 MGD capacity anticipated by 2030.
According to Engineering and Planning Manager Greg Dell, flow to the existing Stone Dam Wastewater Treatment Plant on Stanley Russ Road will be diverted to the new plant. Stone Dam was built in 1979 as a conventional activated sludge treatment plant with 6 MGD capacity.
“We will continue to use the ponds at Stone Dam for equalization,” Dell said.
The Tupelo Bayou plant will feature advanced treatment technology that includes an activated sludge treatment system. Activated sludge plants encompass a variety of mechanisms and processes that use dissolved oxygen to promote the growth of biological floc that substantially removes organic material in accordance with permit requirements.
