Emergency Sanitary Sewer Line Repairs - Payment
History
On October 17, 2016, staff responded to a call regarding a sanitary main that had been damaged by a contractor working on the LaGrange Road Project at 156th Street. The sanitary main services businesses along the south end of LaGrange road from 156th Street to 159th Street. The contractor, while drilling the foundation for a new traffic signal pole on the southwest corner, punctured the 12” sanitary sewer main located 18 feet below ground. Airy’s, Inc. of Tinley Park, Illinois was contacted to evaluate and complete the emergency repair. Due to the depth, the repair was made using the cured-in-place pipe (CIPP) method. The repair is a trenchless rehabilitation method that inserts a liner within the pipe. Hot water, UV light, or steam is used to cure the resin in the liner to form a tight-fitting, jointless and corrosion-resistant replacement pipe. The total cost of this emergency repair was $5,670.00. A contract is in place between the Village and Airy’s, Inc. to perform this type of emergency work.
Correspondingly, the same contractor working on another traffic signal foundation at the northwest corner of 153rd Street and LaGrange Road also punctured a sanitary service line branching from a separate sanitary main. Airy’s was able to make this emergency repair at a cost of $2,398.49.

The concrete pour was performed at the location of the recently repaired CIPP sanitary sewer section. The concrete traffic signal foundation extends 21 feet below the road surface. Based on the damage already incurred, the contractor installed a steel “casing” to contain the concrete and prevent the surrounding ground from collapsing into the hole. The contractor failed to ensure the casing adequately protected the newly made pipe repair. The sheer weight of the conc...
