The challenge

Alberici faced the challenge of upgrading Gwinnett County’s Crooked Creek Water Reclamation Facility to modern standards, ensuring safety, efficiency, and compliance. The outdated processes and structures required extensive modifications to align with state and federal regulations. The $132 million renovation aimed to enhance the facility’s capacity to manage up to 16 MGD of wastewater flows, meeting Georgia water quality standards.

Challenge met

To address these challenges, Alberici executed a comprehensive strategy. Upgrades encompassed various aspects of the facility, including biological reactor basins, odor control facilities, clarifiers, pumping stations, and electrical buildings. Alberici phased the construction, facilitating multiple outages, tie-ins, and process transitions within the operational plant. Maintaining plant operations was paramount, requiring strategic coordination with operators.

Alberici’s proactive approach included self-performing critical work including concrete, process piping and process equipment, yard piping, and electrical ductbanks, which ensure tight control over quality, schedule, and ongoing plant operation. By adeptly managing process changes and maintaining coordination, Alberici successfully navigated the complexities of construction while keeping the plant operational. The project concluded with the facility meeting its upgraded standards, enhancing its capabilities for efficient and compliant wastewater treatment.
