Eventually, Coweta County will need additional sewer capacity, and the Coweta County Water and Sewerage Authority is in the early stages of planning expansion of its wastewater plant.
A public meeting on the expansion plans will be held Tuesday evening. The meeting is at 6 p.m. at the Coweta Water and Sewerage Authority headquarters, 545 Corinth Road, Newnan.
The Shenandoah Wastewater Treatment Plant on Poplar Road can currently treat up to two million gallons per day of wastewater. The plant was designed to be easily expandable, and the upgrade will bring the capacity to 4 MGD.
The Georgia Environmental Protection Division requires that the public hearing be held before the authority can submit its Environmental Impact Document for the expansion plan, said Authority COO Rick Jones.
At the meeting, “we will have a brief summary of what we are planning on doing at Shenandoah and what the expansions will entail,” Jones said. Then, “we’ll open the floor to customers or residents to express any concerns or, hopefully, support for what we are doing."
According to the public notice of the meeting, one purpose of the public meeting is to encourage public involvement in the development of a plan to improve the wastewater treatment system. The notice states that the meeting will attempt to identify public preferences for alternative methods of improving the authority’s wastewater treatment facility. Those alternatives will be evaluated and included in the Environmental Impact Document.
Though the plant’s capacity will double, the footprint of the facility will grow very little. “There is not a lot of change from what we are doing right now and how we are doing it,” Jones said. “It’s just going to allow us to treat 2 MGD more."
Currently, the average use at the plant is 1.3 to 1.4 MGD, Jones said. “The general rule of thumb is when you get to 80 percent, you start looking at upgrades,” Jones said. “We’re not quite there, but we are certainly approaching that 80 percent."
The authority has been looking at upgrades for a while, Jones said. “Obviously with the development that is taking place throughout Coweta County and the industries that are coming in, we just need to be prepared for what the future holds.”
