Chicago— Kenny Construction is working under three term contracts valued at $26 million each for the city of Chicago's Department of Water Management (DWM) to renew aging wastewater pipe in the city's 100-year-old system. Kenny is using Inliner Technologies' method of cured-in-place pipe to rehabilitate up to 360,000 feet of combined sewer pipe over a five-year period, with each contract having a two-year option to renew.

The city is home to more than 4,400 miles of sewer, which has deteriorated throughout the years and is prone to collapse. DWM divided the rehabilitation area into three districts — North, Central and South. The contracts call for renewal of up to 120,000 feet of combined sewer pipe in each district to restore structural integrity and reduce inflow and infiltration.

Under this term contract, Kenny provides up to three crews to work the three areas, which are divided as south of 63rd Street, between 63rd Street and North Avenue, and north of North Avenue. Most pipes in these areas range between 10 inches and 48 inches in diameter.

The DWM is utilizing robotic cameras to record pipe conditions and investigate which areas need to be targeted first for rehabilitation. Kenny will then renew the pipes using Inliner's cured-in-place pipe method.
