Superintendent Jason Manning explains how the clarifier works at GUC’s Wastewater Treatment Plant during a tour in 2015. GUC needs to replace one of its five clarifiers, due to its cracked concrete floor.

Greenville Utilities Board of Commissioners learned Thursday the organization expects to spend $6 million replacing a tank critical to wastewater treatment because of damage that recently was discovered.

The replacement project costs should not cause customer sewer fees to rise, said David Springer, GUC’s assistant director of water resource. However, it did require rearranging several planned capital improvement projects at the wastewater treatment plant.

GUC needs to replace one of five clarifiers located at the treatment plant. Clarifiers are concrete tanks used to remove large solids from wastewater before it continues through the treatment process. Three of the tanks are 35 years old and one has a cracked concrete floor. The damaged was caused by buckling of the ground underneath the tank, Springer said. The damage was discovered in May during routine maintenance of the three tanks.

The tank provided 20 percent of the plant’s clarification capacity, Springer said. With it out of commission, there are concerns about the plant’s ability to treat high flows that occur during hurricanes and flooding rains.

The North Carolina Division of Water Resources advised GUC to restore the capacity or risk seeing it plant capacity reduced, which could slow customer growth, Springer said. GUC current maximum treatment capacity is 17.5 million gallons daily. The plant typically treats 10.5 million gallons daily.

Staff is proposing the damaged tank be replaced by two new clarifiers. Springer said adding another tank, which would bring the total to six, would enhance the existing treatment process and increase treatment capacity to about 22.5 million gallons daily. Increasing capacity was a need identified in GUC’s 2014 master plan for the plant, he said.

Staff will ask the GUC board to officially establish a sewer capital budget in August, Springer said. Staff are looking at applying for a grant that was partially fund the project.

News of the replacement came the same day two new individuals joined the board and a new slate of officers were selected.
