WASTEWATER TREATMENT PLANT

WALKER COUNTY WASTEWATER TREATMENT PLANT:

The Walker County Wastewater Treatment Plant (WWTP) is located in Chickamauga near Highway 27. The WWTP receives its flow from Residential, Commercial, and Industrial customers and serves the area around Chickamauga, South on Highway 27 almost to LaFayette, GA, and West to the Mission Ridge Rd area.  The sewer in the western portion of the County, around the Authority’s Main Office and Ridgeland High School, flows to Moccasin Bend Wastewater Treatment Plant in Chattanooga, TN.  All activities of the WWTP, including the various programs, are strictly monitored, inspected, and enforced by the Georgia Environmental Protection Division (EPD).

TREATMENT:

The WWTP is designed to handle an average flow of 3.5 million gallons a day and currently is running at about ½ capacity.  It is an Extended Aeration Activated Sludge Treatment Plant.  Treatment Processes include:  Screening, Mixing, Aeration, Clarification, and Disinfection.  The wastewater is treated and is then discharged into West Chickamauga Creek.  Our sludge (the byproduct of the treatment process) is carefully monitored and tested and is land applied on hay fields as a beneficial use for the farmer which increases hay production as well as decreases the need to purchase fertilizer.   This land application process is also monitored as to when, where, and how much sludge can be applied to a certain field.

LABORATORY:

The WWTP has its own lab and the majority of the tests are preformed in-house.  Industrial and Toxicity samples are analyzed by independent laboratories.  The WWTP discharge has to meet its National Pollutant Discharge Elimination System (NPDES) Permit limits as set by the Clean Water Act and EPD.
