Columbia Metro WWTP Anaerobic Digesters Rehab & Improvements Columbia, South Carolina

M. B. Kahn is currently completing the a $22M upgrade on two of the five anaerobic digesters at the City of Columbia metropolitan wastewater treatment facility. Key modifications to the yard piping were completed to convey co-thickened primary and waste activated sludges from the existing trains one and two. Dissolved air flotation buildings to each anaerobic digester were constructed. Existing equipment, piping, valves, and appurtenances from existing digester head houses were demolished and replaced. New boilers have been constructed as well. Our collaborative approach has allowed the City to phase this project and ensure that the treatment process has not and will not be interrupted during construction. Additional scope of work includes modifications to the electrical, upgrades to the SCADA system, upgrades to the effluent pump station, and improvements to the chemical treatment systems.

We have completed over $60M in upgrades, improvements, and expansions at Columbia Metro WWTP since 2001. Metro WWTP collects wastewater from approximately 63,000 connections located along 1,000+ miles of pipeline and is rated for 60 MGD. We are a proud partner for the City’s ‘Clean Water 2020’ program and member of the Mentor/Protégé program, where we support growth and development of minority-owned businesses through job-site mentorship.
