Abstract: The Metropolitan Water Reclamation District of Greater Chicago (MWRDGC) owns intercepting sewers and seven water reclamation plants, but 125 local communities own the local sewers which collect the sewage. These local systems contribute excess infiltration and inflow (I/I) which must be removed in order to comply with USEPA requirements. Each local community is responsible to conduct its own sewer system evaluation and rehabilitation program. In order to track the progress of the program, the MWRDGC is computerizing semiannual data reports from the local communities. Between 1987 and 1991, the local communities will spend an estimated $140,000,000 to complete the sewer system repairs. Studies are being conducted to determine what new systems, if any, will be needed to accommodate the residual excess I/I after local rehabilitation is completed.
