Rome Water Pollution Control Plant

Atlantic Skanska has begun work on this $34 million project from the City of Rome in Georgia to improve their Water Pollution Control Plant (WPCP). The project requires procurement, installation and commissioning of all associated equipment. Due to a marked increase in the number of residents in the area, the existing plant no longer has the capacity to meet local needs. The equipment at the facility is also old and in need of replacement. Currently the plant treats 23 mgd, upon completion it will be able to treat up to 54 mgd.

The scope of work consists of constructing a new influent pumping station, with new course bar screens as well as connecting the existing 60-inch interceptor to the new influent pumping station. New preliminary treatment facilities for removal of screenings and grit will also be installed and the project team must convert the existing equalization facilities from in-line to off-line storage, remove the piping constrictions with in the existing plant and provide secondary treatment for all flows. Two new circular secondary clarifiers will be installed and the two existing secondary clarifiers will be modified by installing peripheral launders. Construction of a new return activated sludge pumping station, waste activated sludge pumping station and chemical feed facilities for removal of phosphorus are also part of the contract. Installation of a new Supervisory Control and Data Acquisition (SCADA) system are also part of the control as well as construction of miscellaneous flow control structures, new aeration equipment for thickening of waste sludge and expansion of the existing Administration Building.

The contract includes all mechanical, electrical and instrumentation work that is required as part of the upgrade project. The project team is also responsible for installation of 15,700 cubic yards of concrete and excavation of 70,000 cubic yards of earth.
