The Midwest City Pollution Control Facility was in need of upgrades to comply with new and anticipated future discharge permit criteria. Upon completion of this project, involving improvements to both the liquid and solids wastewater treatment processes, the MWCPCF will have a 10.2 MGD rated capacity and will be utilizing the first Moving Bed Biofilm Reactor (MBBR) approved for wastewater treatment in the state of Oklahoma. Portions of the facility will need to be kept in continuous operation throughout construction. The work to be performed under this contract consists of constructing a new headworks building, MBBR basins, process air blower building, ultraviolet building, biosolids pumping complex, and concrete flow diversion structures. The project also includes the renovation of several process structures such as primary and secondary clarifiers, primary sludge pump station, four digesters, dechlorination basin, main control building, chlorine building, and secondary digester pumping complex. Site work consists of roadways, a new electrical distribution system, new SCADA system, buried piping and valves, and general site grading.
