Sewer Rehab Planned at Locations throughout Evanston Starting October 23

The City of Evanston will be rehabilitating a portion of the City’s public combined sewer lines using a Cured-In-Place Pipe (CIPP) process. The project will take place from October 23 through December 18, weather permitting. Preparatory work will begin on Monday, October 9.

A map of project locations can be found in the attached newsletter. The contractor performing the work is Kenny Construction Company.

During sewer rehabilitation, a liner is inserted into the public sewer that will seal the building’s sewer service connection, preventing it from flowing into the public sewer. Residents are asked to limit water usage by limiting use of bathroom facilities and refraining from doing laundry or washing dishes when work is being completed outside of their home. Any sump pumps that are connected to the combined sewer system should be disconnected during this time. When installation of the liner is complete, the contractor will reestablish flow from the building sewer service to the public sewer.

Work should take approximately 12 hours to complete at each location. In high-traffic areas, lining work may be performed between 7 p.m. and 7 a.m. to reduce the risk of traffic-related accidents to residents and workers. The contractor will work with area residents and businesses to minimize impacts and noise. A 10-day notice will be provided to area residents prior to lining work. An additional notice will be placed on the front door knob of affected buildings advising the occupants 24 hours in advance of the specific date and time that the sewer lining work will take place. Residents who do not receive a notice will not be affected by the project. “No Parking” signs will be posted in the areas where the rehabilitation work will restrict parking.

The resins used in the lining process are the same resins that have been used in the fiberglass industry for many years, and 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. Residents are advised to not be alarmed if they smell the chemical while the contractor’s personnel are working in their area. The odor can be prevented from entering buildings by pouring a gallon of water into each basement floor drain regularly.

This project will be monitored by the City’s Capital Planning & Engineering Bureau. If you have any questions or concerns, please do not hesitate to contact Civil Engineer Bridget Nash at 847-448-8102 or bnash@cityofevanston.org.
