Gwinnett spends $136M to modernize county’s oldest wastewater facility

Nov 1, 2021

An update to one of Gwinnett’s oldest facilities will help the county more efficiently treat sewage and other wastewater before sending it into the Chattahoochee River, officials announced Tuesday.


“Despite the challenges of rehabilitating this facility while it was still operating, Crooked Creek continued to function normally and received no violations,” County Commission Chairwoman Nicole Hendrickson said in a news release. “This highlights the hard work put in by the Department of Water Resources and the employees who serve the county daily.”


Renovations to the plant — purchased by the county in 1972 — include upgrades to electrical and computer systems, odor control systems, biological reactor basins, solids handling, UV system and clarifiers.
