Water Authority of Dickson County (WADC) Wastewater Treatment Operations consist of: three National Pollutant Discharge Elimination System (NPDES) permitted wastewater treatment plants – the Fairview Wastewater Treatment Plant (FWWTP), the Jones Creek Wastewater Treatment Plant (JCWWTP), and the White Bluff Wastewater Treatment Plant (WBWWTP); two State Operating Permit (SOP) permitted Wastewater Treatment Facilities – Love’s Travel Stops & Country Store Decentralized Wastewater Treatment Facility (LWWTF) and Cumberland Estates Decentralized Wastewater Treatment Facility (CEWWTF); a federally approved Pretreatment Program; and, the skilled team of employees that it takes to run each on an ongoing basis.
WADC’s Wastewater Treatment Plants are oxidation ditch systems that discharge to specific tributaries that each eventually flow into the Harpeth River. The treatment plants consist of:
WADC operates the treatment plants using standard operating procedures, consistent with oxidation ditch theory and sound-activated sludge methodology. Each facility consistently produces a clear, sparkling effluent that reliably meets discharge permit standards.
Fairview Wastewater Treatment Plant
FWWTP has a design capacity of 0.46 MGD. The facility sets on a 10.45 acre secluded tract in Fairview near Flat Rock Branch, into which final effluent is discharged. FWWTP was constructed in 1990 by the City of Fairview who owned and operated it until its Water and Wastewater Department consolidated with WADC in 2006. A project was completed at the end of 2020 to upgrade the process to a 5 stage Bardenpho process in order to meet low phosphors and total nitrogen limits. The workforce at FWWTP includes two WADC employees.
Jones Creek Wastewater Treatment Plant
JCWWTP has a design capacity of 4 MGD. The facility sets on a 42 acre tract in Dickson bordered the length of one side by Jones Creek, into which final effluent is discharged. JCWWTP was constructed in 1970 and had a major upgrade in 1994. The workforce at JCWWTP includes seven WADC employees.
Cumberland Estates Decentralized Wastewater Treatment Facility
CEWWTF has a design capacity of 0.081 MGD and is located at the 1060 block of Brayden Drive in Fairview. CEWWTF features septic tanks, an effluent collection system, recirculating media filter and a fenced drip irrigation system. The system serves approximately 270 homes in the Cumberland Estates housing development.
Love’s Travel Stops & Country Store Decentralized Wastewater Treatment Facility
LWWTF has a design capacity of 0.015 MGD and is located at 2971 Highway 48S in Dickson. LWWTF features a septic tank, recirculating sand filter and a fenced drip irrigation system. The system serves the Love’s Travel Center and Country Store site.
White Bluff Wastewater Treatment Plant
WBWWTP has a design capacity of 0.5 MGD. The facility sets on a 5.35 acre tract in White Bluff near Trace Creek, into which final effluent is discharged. WBWWTP was constructed in 1968 (and had a major upgrade in 1992) by the Town of White Bluff, who owned and operated it until its transfer to WADC January 1, 2015. The workforce at WBWWTP includes two WADC employees.
WADC’s Pretreatment Program is responsible for enforcing Federal, State, and Local environmental regulations authorized by the Clean Water Act in relation to the Pretreatment Program. This includes monitoring and inspection of all Significant Industrial Users (SIUs) within WADC’s coverage area to prevent the introduction of pollutants into the WWTPs which will interfere with the operation of a WWTP, including interference with its use or disposal of municipal sludge, and, to prevent the introduction of pollutants into WWTPs which will pass through the treatment works or otherwise be incompatible with such works. WADC currently has 12 permitted Industrial Users in the Pretreatment Program.
Another segment of the Pretreatment Program is the FOG Management Program. Through the FOG Management Program the Pretreatment Division oversees Food Service Establishments (FSEs) or other commercial businesses that may have the potential to negatively impact the collection system via fats, oils, or greases.
FSEs discharging to the WADC collection system are subject to the program and related design standards, procedures, or guidelines. The purpose of this program is to protect the WADC collection system, pumping stations and treatment works from the discharge of excess FOG by ensuring that FSEs are in compliance with the requirements of the program. WADC currently has over 100 FSEs (or other commercial users) in the FOG Management Program.
