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.
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.
Additional information about WKUD's FOG Program may be obtained by contacting
our office at (865)690-2521 ext. 210.
