Illicit Discharge Detection & Elimination

An illicit discharge is defined as any discharge to the storm sewer system that is not composed entirely of storm water.  These non-stormwater discharges occur due to illegal connections, dumping, and improper disposal into the storm drain system from business or commercial establishments.   There are some exceptions for discharges allowed under a NPDES permit or waters used for firefighting operations.  The Town of Collierville's illicit discharge detection and elimination program is designed to prevent contamination of ground water supplies and surface waters by monitoring, inspection and removal of these illegal non-stormwater discharges.

Prohibited non-stormwater discharges include, but are not limited to, sanitary wastewater, car wash wastewater, raditator flushing disposal, spills from roadway accidents, carpet cleaning wastewater, effluent from septic tanks, improper oil disposal, laundry wastewater/gray water, or improper disposal of auto and household toxics.  

Hot spots are areas where land use or activities generate highly contaminated runoff, with concentrations of pollutants in excess of those typically found in stormwater.  The following land uses and activities are deemed stormwater hot spots, but that term is not limited to only these land uses:

a.  Vehicle salvage yards and recycling facilitiesReportIllicitDischarge

b.  Vehicle service and maintenance facilities

c.  Vehicle and equipment cleaning facilities

d.  Fleet storage areas (bus, truck, etc.)

e.  Industrial sites

f.  Resturants and food service facilities
