Wapakoneta WTP (CMAR)

The City of Wapakoneta selected PCC as CMAR for an $18.2 million lime-softening conversion upgrade at their WTP. The project scope included conversion of the existing ion exchange softening WTP to a lime softening WTP. Components of the project included relocation of existing aerators, a new carbon dioxide feed building complete with a pressurized solution feed (PSF) carbon dioxide feed system, (2) new solids contact clarifiers, conversion of existing tankage to a recarbonation basin, a new chemical building with lime and soda ash feed systems, a new clearwell, and conversion of space within the existing treatment building to administrative areas.
