More upgrades are in store for the Crooked Creek Water Reclamation Facility at 6557 Plant Drive in Peachtree Corners after Gwinnett commissioners signed off on an $8.86 million contract for engineering design and construction support on July 15.
The 71-month contract covers project management, preliminary engineering, detailed design and construction administration. CH2M Hill Engineers Inc. was selected as the highest-scoring of four short-listed bidders. Systems involved include chemical addition, activated sludge treatment, secondary clarifiers, disinfection, post aeration, solids handling and electrical systems. Work will begin this fall and end when construction is finished in 2020.
Previous projects over the past five years included a new influent pump station, headworks building, operations center, maintenance facility, diffused air conversion and filter rehabilitation.
The 20-year-old plant treats up to 16 million gallons of wastewater per day. Water Resources Director Ron Seibenhener said, “These modifications will ensure cost effective operations that meet or exceed all permit requirements. It will be a facility that will continue to serve the needs of Gwinnett residents and our downstream neighbors for decades to come.”
