The Story

Big Creek Water Reclamation Facility was first constructed in (1969/1971). At the time, it was designed with a treatment capacity of 0.75 million gallons per day (MGD).

During its lifetime, Big Creek Water Reclamation Facility has been upgraded/expanded several times. The most recent and noteworthy expansion occurred in 1991, at which time the facility was expanded to its current permitted capacity of 24 MGD.

The planned expansion will increase the facility’s permitted capacity to 32 MGD. This will allow it to better serve its service area of over 70 square miles that includes Roswell, Alpharetta, portions of Milton and areas of Cobb and DeKalb counties. The Metropolitan North Georgia Water Planning District forecasts continued population growth and economic development, so the facility will require additional capacity to keep up.
