Major milestone reached - Startup and commissioning have begun at the Effingham County Wastewater Treatment Plant in Effingham County, Georgia.
This 2.0 MGD expansion includes new headworks, aeration basins, clarifiers, filtration, UV disinfection, and a 6-million-gallon storage pond, providing reliable wastewater treatment for the county’s growing community for years to come.
We’re proud to work alongside @EffinghamCounty on this important project.
We were excited to welcome the @gawp.water and our industry partners to the Custer Avenue Capacity Relief Storage Facility for lunch and jobsite tour!
Guests heard from several speakers about the project, its impact on the Peoplestown neighborhood, and how it will protect the community for years to come.
The 20-million-gallon buried vault will temporarily store flow during large storms and gradually drain once wet weather passes, helping prevent future flooding and improve water quality.
Thank you to everyone who joined us!
