The Watershed Management Ordinance (WMO)

The Watershed Management Ordinance (WMO) applies to all development within the boundaries of Cook County, Illinois, and qualified sewer construction within the MWRD’s corporate boundaries or service agreement areas. Components which are regulated under the WMO include qualified sewer construction, drainage and detention, volume control, floodplain management, isolated wetland protection, riparian environment protection, and soil erosion and sediment control. The WMO went into effect on May 1, 2014 and the MWRD’s Board of Commissioners most recently amended the WMO on May 16, 2019. The WMO is accessible through the link below.

Infiltration/Inflow Control Program

Excessive infiltration and inflow (I/I) into the sanitary sewer system is a serious problem that contributes to sanitary sewer overflows (SSOs) and basement backups (BBs). The Environmental Protection Agency (EPA) and the Illinois EPA (IEPA) imposed special conditions in the National Pollutant Discharge Elimination System (NPDES) permits issued for the MWRD’s Water Reclamation Plants (WRPs) that requires tributary local separate sanitary sewer satellite entities to implement measures in addition to those required under the 1985 Sewer Summit Agreement if excessive I/I in the system causes or contributes to SSOs or BBs. Due to this mandate, the MWRD incorporated an updated Infiltration and Inflow Control Program (IICP) that was developed with the help of an Advisory Technical Panel (ATP) into the Watershed Management Ordinance (WMO).
