Kenny uses Inliner to renew aging sewers.

Kenny Construction has begun work under three term contracts valued at $26 million each for the city of Chicago, 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 (CIPP)

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 (I/I). Most pipes in these areas range between 10 and 48 inches in diameter.

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

The contract also encompasses lateral lining and point repair work, with large-diameter pipe lining being bid separately.
