Peak Capacity

240 MGD

WWPS upgraded and integrated a complex instrumentation and control system at RM Clayton WRC, one of the largest wastewater treatment plants in the southeastern United States. The RM Clayton plant continuously receives and treats wastewater averaging 122 million gallons per day (mgd), with peak capacity of 240 mgd.

The project included intricate instrumentation and controls work, trenching, installation of concrete encased duct bank, and placement of more than 20,000 feet of fiber optic cable and conduit in existing tunnels. Careful sequencing and coordination was critical as this project was completed in an operational facility, with concurrent construction activity. Additionally, the team overcame unforeseen issues with existing systems discovered while working in the tunnels.  

WWPS applied best-in-class management techniques to drive the project, including top-notch critical path, cost-loaded scheduling and dedicated quality control/quality assurance and safety managers providing oversight, training and monitoring. Pre-work planning emphasized safety first, and WWPS built custom tools and systems to enable work to proceed in a safe, efficient manner. 

The team held numerous workshops to study and resolve issues while key subcontractors provided expertise to help resolve critical challenges. A formal partnering process brought the City of Atlanta, WWPS, subcontractors and engineers together and laid a foundation for moving forward as a team.
