West Knox Utility District


Pretreatment Program

The Environmental Protection Agency (EPA) requires that a Publicly Owned Treatment Works (POTW) Facility receiving pollutants from industrial users which could pass through and/or interfere with the operation of the POTW develop and implement a Pretreatment Program.

The primary purpose of the Pretreatment Program is to protect the operational performance of the wastewater treatment facility and water quality of the receiving stream through control limits on industry discharges into the sewer collection system. Industries must meet specific wastewater constituent limits in their discharge before a permit is issued by West Knox Utility District. WKUD issues permits to industrial wastewater dischargers, samples permitted dischargers, and ensures that all laws and regulations are complied with. Sample data collected by the pretreatment section are used in the calculation of surcharge fees.

The responsibility of the Industrial Pretreament Program is to sample and inspect industrial facilities and regulate discharge of industrial waste into the sanitary sewer system, as well as to monitor and inspect food service establishments to prevent the discharge of Fats, Oils, and Grease into the sanitary sewer system.

Pretreatment Permits

Wastewater permits are issued to significant industrial users. Permits may be issued for up to five (5) years. Permit applications or information about the Pretreatment Program may be obtained by contacting WKUD's wastewater treatment plant at (865)690-2521 ext. 234.

Fats, Oils and Grease (FOG) Control Program

All food service establishments are inspected routinely to ensure proper removal of Fats, Oils, and Grease wastes. The primary purpose of the FOG Program is to prevent sanitary sewer system blockages, obstructions, and overflows due to the contribution and accumulation of FOG from food service establishments and other non-residential facilities where food is prepared and served.
