Learn how the City:
The Disinfection Improvements for the Metro WWTP Consent Decree Early Action Project (EAP) have eliminated plant dependence on hazardous gaseous disinfection chemicals and aging gas feed equipment which posed a safety threat to personnel and the surrounding community.
The Metro Wastewater Treatment Plant Train II DAF Improvements Consent Decree Early Action Project (EAP) replaced worn process equipment and assessed other components for wear and future replacement needs. The project allowed the City to meet SCDHEC's effluent requirements and increase efficiency and reliability.
The Metro Wastewater Treatment Plant Standby Pump Station Improvements and Effluent Flume Modifications Consent Decree Early Action Project (EAP) included improvements to the standby pump station's capacity and hydraulic operating conditions, and modifications to the effluent flume structure.
The Metro Wastewater Treatment Plant Aeration Consent Decree Early Action Project (EAP) provided upgrades to four aeration treatment basins and critical operating processes increasing efficiency and reliability and reducing costs.
The improvements during this Consent Decree Early Action Project (EAP) to the Broad River Pump Station addressed the existing hydraulic, electric, structural and HVAC deficiencies and increased the station's pumping capacity thereby reducing the potential for sanitary sewer overflows.
