The Illinois Department of Transportation contracted to have the sewers and laterals along the Chicago area expressways cleaned in order to prevent flooding after storms. Debris composed of sand, silt, and dirt from cars and pavements was removed and hauled away by the National Power Rodding Corp. of Chicago which employed closed circuit TV inspection of pipe conditions. For the larger lines, horseshoe-shaped disc scrapers pulled by power winches were employed. Jetting by power rodding was used for the smaller lines. Benefits resulting from this cleaning included the restoration of the total capacity of drainage lines, the location of damage permitting repairs before it was too late, and the prevention of solids blocking pumping stations. The Illinois Department of Transportation has found that sewer line cleaning is essential in maintaining a system that keeps expressways free of delays at all times.
