Modifications and upgrades at Gwinnett County’s Crooked Creek Water Reclamation Facility will improve plant safety, efficiency, and reliability. Advances in treatment technology have rendered several processes and structures at the facility outdated, requiring upgrades to comply with state and federal regulations. This massive $132 million renovation project being constructed by Alberici will allow the facility to handle up to 16 mgd wastewater flows in accordance with Georgia water quality standards.

The sequence of construction requires multiple outages, tie-ins, and process changes within the existing plant, which must be completed without any spills or process interruptions. To ensure that plant operations continue uninterrupted throughout construction while also controlling schedule and quality, Alberici is self-performing significant scopes of work including cast-in-place concrete, yard piping, interior process piping, and mechanical work.  As part of the Alberici team, WWPS was responsible for running duct bank and vaults for all new power feed, including a redundant system, and all new backbone for the SCADA system.
