UW-L's storm water discharge permit prohibits illicit discharges to the storm sewer system.

Illicit discharge is defined as any discharge to the municipal separate storm sewer system that is not composed entirely of storm water, except for discharges allowed under a National Pollution Discharge Elimination System (NPDES) permit or other discharges allowed locally. These non-storm water discharges may be due to illegal connections to the storm sewer system by commercial, industrial, or sometimes residential properties. The illegal connections allow contaminated wastewater to drain untreated to our waterways. Failing septic systems and illegal dumping are also illicit discharges.

It is important to note that there are many non-storm water discharges that are not considered illicit discharges. These include such discharges as water-line flushing, landscape irrigation, lawn watering, and water used for fire fighting.
