Abstract: After a number of public hearings in the late 1960's and early 1970's which focused on sewer backup problems in the Sanitary District's separate sewer area, a comprehensive program for the correction of existing deficiencies in separate sewered areas was initiated on January 1, 1973. The purpose of the program was to alleviate the widespread occurrence of basement flooding throughout the Sanitary District's service area; to reduce the overloading of local sanitary sewer systems and Sanitary District interceptors; to prevent pollution; and to comply with United States Environmental Protection Agency (USEPA) regulations. In late 1985 the Sanitary District's Sewer Permit Ordinance was revised to incorporate an Infiltration/Inflow Corrective Action Program (ICAP) as an alternative to the existing 150 program. The ICAP program option and its present status are discussed.
