Plant History: This is a new facility. The City of Winder has previously operated a conventional wastewater treatment facility designed by Davis Industries for many years. This new facility is based on a Seghers design concept. This facility has increased the peak design flow to 3.75 MGD.

Plant Description: The facility will receive domestic waste from the City of Winder. The treatment process steps include screening, de-gritting, aeration, sedimentation/clarification, coagulation, filtration, UV disinfection, flow measurement with dual discharge capability to either Marburg Creek or the re-use facility for Golf Coarse Irrigation.

Tertiary Filters: The twelve (12) Centra-flo Gravity Sand Filters Model CF-50C are constructed of fiberglass and installed into the concrete basin provided by others. The filters operate as six (6) independent cells with two (2) modules per cell. Each cell has 100 ft2 of total filtration area. The filtered water is to be used for irrigation of the new Municipal Golf Coarse and will produce water with 3 NTU or less. Peak flow to the filter facility is 3.75 MGD or 4.34 gpm/ft2. Average flow will be 1.5 MGD or 1.74 gpm/ft2.

Filter Startup: The Centra-flo filters were installed in July 1999. Equipment startup was completed and the filter system was operational in early January 2000. Facility to be on-line February 1, 2000.
