Cornelia Water Main Replacement
Water Main Project #: 180104
Start Date: 3/11/2019
Tentative Completion Date: Late April
Status: Water Main Complete. Under Restoration
Through Mayor Rahm Emanuel’s Building a New Chicago infrastructure improvement program, the Department of Water Management (DWM) is installing a new water main in your area on
Project No: 1801043
- ON W CORNELIA AVE FROM N HALSTED ST TO N BROADWAY
By signing up for these notifications on the buildinganewchicago.org website you will be kept informed on the progress of this project.
Construction crews have begun preparing the site for the water main installation, including the location and marking of other utility services. You will notice construction equipment and materials placed in your area. The project will consist of several phases over the coming weeks.
Once the new water main has been installed, the new pipe will be pressurized, disinfected with chlorine and tested. We will then begin the process of switching services from the old main to the new main. During that transfer period you will be without water for a few hours. Your building will receive a handout notifying you when your water service will be temporarily interrupted prior to the service transfer.
Flushing after Your Service Line has been Connected to the New Water Main
Once your old water main has been replaced and your water service has been connected to the new water main, it is important to flush your plumbing of any sediment, rust or metals, including any lead to maintain water quality.
Sediment, rust and metals, including any lead may collect in the aerator screen located at the tip of your faucets. These screens should be removed prior to flushing.
If your water line has been idle or stagnant for more than 6-hours, it is advised that you flush for at least 5 minutes to maintain water quality. This may include flushing the toilet, taking a shower and doing laundry.
Once the services have been transferred, the street will be temporarily restored with concrete until complete restoration of the street with asphalt can be done. ADA-compliant sidewalk ramps will be repaired or installed where needed, along with repair of damaged parkway and sidewalk. The final restoration of the street will include milling the surface, placing new asphalt, and painting the street markings.
The restoration schedule is subject to change and may be impacted by adverse weather conditions. Asphalt is not available during winter months, which may delay the final restoration of the street. Final restoration will occur late spring.
You will receive additional notifications as the project proceeds.

In mid-January 2019, Department of Water Management crews will begin the work to install 804 feet of new 8-inch water main in W Cornelia Ave from N Halsted St to N Broadway. The old water main dates back to 1891, and needs to be replaced.
When crews are working in the street, they may close or limit it to traffic for safety reasons, but you will always be able to reach your home or business. Outside of working hours, a travel lane will be left open for local traffic only.
Crews will post the work area for “No Parking” as needed during work hours (generally 7am-4pm). Parking outside of those hours will be allowed, but cars will need to be moved by the start of the next workday. Crews will try to preserve as much parking space as possible.
We know that construction always involves inconveniences and noise. Crews will do everything possible to maintain your quality of life throughout the project, and conduct themselves as good and thoughtful neighbors in the course of their presence on your street.
