The Metropolitan Water Reclamation District of Greater Chicago (MWRD) through congressional action, transferred maintenance responsibilities of all pool retention structures to the U.S. Army Corps of Engineers in the early 1980s. The U.S. Army Corps’ Rock Island District, in coordination with the MWRD, is implementing a $110 million multi-year program to repair the Chicago Sanitary and Ship Canal embankments along the three-mile upper pool approach area to Lockport Lock and to rehabilitate the Lockport Controlling Works in Lockport, Ill. The concrete Lockport Canal Wall is in an advanced state of deterioration that affects wall stability. The wall was built in the 1890s and last significantly repaired in the 1920s. Rehabilitation of the wall involves placement of new structural precast concrete panels along the existing canal face for approximately 2 miles. The project is located within a three-mile reach of the Lockport Lock Pool of the Illinois Waterway (river mile 291.0 – 294.0) at Lockport, IL. As part of the Chicago Sanitary and Ship Canal, which extends from the Chicago River to the Illinois Waterway, the Lockport upper pool is a perched pool (38-feet above the surrounding area), with a roughly forty-five-foot-high embankment on the right descending bank and a concrete canal wall on the left descending bank.
The U.S. Army Corps of Engineers, Rock Island District, awarded a $64,000,000 construction contract to Walsh Construction Company of Chicago for rehabilitation of the left descending Lockport Canal Wall. INTERRA was retained by Walsh Construction Company to install a total of six observation wells to depths of 40 feet from the top of embankments through challenging embankment materials.
