FEATURED WASTEWATER PROJECTS

City of Cayce 25-MGD Wastewater Treatment Plant

All New BNR facility designed for a capacity of 25 MGD, and replaced a 9.5 MGD plant. Design included a headworks structure with influent screening, grit removal and odor control; a Biological Nutrient Removal process, six secondary clarifiers, return and waste activated sludge pumping stations, chlorine contact tanks, post aeration, an effluent pump station, chemical feed facilities, an aerobic digestion/membrane thickening process, a sludge de-watering facility; a laboratory building, a Supervisory Control and Data Acquisition system, and ancillary facilities. This multiple State and National award winning facility was completed twenty percent below budget and fifty percent below the average per gallon cost of typical treatment facilities.

East Richland County Public Service District 64-Inch Interceptor Sewer Line

Design, construction oversight and contract administration for the replacement of approximately 2,500 LF of existing 54-Inch and 42-Inch diameter gravity sewer. The line is situated in an environmentally sensitive area, and transports all wastewater flow from the District’s service area into the Quail Lane Pump Station, from which it is pumped to a 16-MGD treatment facility.

Town of Lexington 31-MGD Pump Station Upgrade

Design of a new 31 MGD pump station, including modifications to the existing pump station and construction of new wastewater screening equipment, wet well structure with submersible pumps, lime feed system, new odor control system, new bridge crane structures, new back-up power generator, and SCADA system and instrumentation.

City of Columbia 160-MGD Metro WWTP Effluent Diffuser

Design of effluent diffuser into the Congaree River, post-aeration system, dechlorination system and pump station for peak discharge of 160- MGD. Services included evaluation of diffuser design utilizing hydraulic modeling software. This project received the Engineering Excellence Award from the American Council of Engineering Companies. The environmental permitting difficulties and challenges in dealing with a shallow navigable waterway during installation of a wastewater effluent diffuser were contributing factors in receiving this award.

Lower Richland Wastewater Treatment Facility Replacement

Following catastrophic structural damage in a portion of its existing WWTP, AEC was retained by Richland County to design and construct a new 1.0 MGD Wastewater Treatment Facility to service lower Richland County. Construction included a Headworks structure, two Biological Nutrient Removal Basins, two Clarifiers, a RAS/WAS pump station, Sludge Digester, Decant Pumps, and Membrane Grid Aeration Diffusers. The work consisted of structures, equipment, site work, yard piping, mechanical piping, electrical and all necessary appurtenances for a complete wastewater treatment facility.
