The City of Evanston’s Utilities Department announces that traffic will be reduced to one lane in each direction for sewer rehabilitation work on Golf Road. The city has contracted with Insituform Technologies USA, LLC (Insituform) to rehabilitate approximately 1,960 feet of 60” diameter brick sewer on Elgin (Golf) Road between Lincolnwood Avenue and McCormick Boulevard (see map here>>>). Initial work will begin Monday, April 29. Actual sewer liner installation and restoration work will run from May 6 to May 24 with some nighttime work involved.
The rehabilitation work includes installing a cured-in-place pipe (CIPP) liner inside the existing sewer mains. This process is generally less disruptive and the work can be completed much faster than if the sewer were excavated and replaced. In order to facilitate the installation of the liner, a new manhole will be installed.
If a resident smells the styrene while the contractor’s personnel are working in the area, they should not be alarmed. The resins used in the lining process are not new. They are the same resins used in the fiberglass industry for many years. These resins contain a chemical called styrene that hardens when heated. Although styrene is not a pleasant odor, it is not dangerous at the levels at which people can detect it.
Installation of the manhole is anticipated to start the week of April 29, 2013. A modified traffic pattern will be established on Golf Road with only one lane of traffic in each direction and both lanes traveling on the south side of the street.
The installation of the liner is anticipated to start the week of May 6 and be completed by May 17, 2013. The liner will be installed in two steps: from the new manhole west to Lincolnwood Drive and then from the new manhole east to McCormick Boulevard. Each step will take approximately one week to complete. During that time, there will be four days when the contractor will need to work 24 hours a day until the installation is complete.
Restoration of the site will occur during the week of May 20 and the normal traffic pattern will be resumed by May 24, 2013.
