Crooked Creek Water Reclamation Facility

Crooked Creek Water Reclamation Facility (WRF)

The Crooked Creek WRF is located in Peachtree Corners on a 45-acre site off Holcomb Bridge Road, approximately one mile southeast of the Chattahoochee River and the Fulton County line. Crooked Creek WRF is one of three water reclamation facilities in Gwinnett County. 

In March of 2017, Gwinnett County Department of Water Resources (DWR) began Phase 4 of the upgrade and modernization project at this facility. During this project, DWR will be making upgrades to the electrical and computer systems, biological reactor basins, solids handling and clarifiers.  These enhancements will result in better environmental protection, odor control and noise control.

Construction is scheduled to be completed May 2021.

A May 2018 update with additional details of the project is available here.
