City of Atlanta

To solve a chronic grit-removal issue at the City of Atlanta’s largest wastewater treatment plant, the 240-million-gallons-per-day RM Clayton Water Reclamation Center, this project performed upgrades to the headworks facility while replacing the existing coarse screening and grit removal systems and installing new influent flow-monitoring equipment. Completed on time despite a delayed start date, the work included a new 12-cell multi-tray grit removal structure and dewatering building; upgrades to process equipment, 26 electric sluice gates, electrical systems and integration with existing digital control system. The work also called for excavation and drill-and-shoot of 35-foot sloped and 40-foot vertical areas within the facility.
