The Village of Glen Ellyn has adopted an ordinance that is designed to protect local water systems from polluted water. The ordinance, which was approved at the village's Oct. 26 meeting, establishes regulations for illicit water discharge detection and elimination.

The ordinance also creates an intergovernmental agreement between the village and DuPage County.

If polluted water is suspected to be entering the streams that carry storm water from the village, the county would conduct an investigation and ask the village to help it trace the source of the illicit discharge, once the agreement is approved on the county level.
