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 District’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 District
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). |
||
The IICP is defined in Article 8 of the WMO. | ||

The District and the ATP developed the Technical Guidance Manual (TGM) which serves as a technical reference to the IICP. | ||
