Caldwell Avenue 12” and 20” Water Main River Crossing Project


Village of Morton Grove


Morton Grove, IL


Ciorba Group was selected by the Village of Morton Grove for preliminary, final design and construction engineering services to replace approximately 1,200 feet of parallel 12-inch and 20-inch water mains, 2,400 ft total, through the Cook County Forest Preserve District and under the North Branch of the Chicago River.. The existing segment of water main has been repaired due to several leaks and has demonstrated severe deterioration attributed to corrosive soil in the area.  The existing WaterCAD model was used to evaluate the options of replacing the water mains in-kind or combining them into one larger water main. Among the factors included in the evaluation were cost, maintenance, and constructability.  The results of the analysis were summarized in an alternatives analysis memo.  Ciorba has prepared the pre-final design plans, specifications, and engineer’s cost estimate, as well as the documentation for permit submittals.
