Site work for a water / sewer project in Northbrook, Illinois. Conceptual plans call for site work for a water / sewer project.

The 12-inch cast iron main that runs on Lee Road from Dundee to Rudolph was installed in 1968. The water main has a crossing under the Edens Expressway Spur. The Village's water distribution system has limited capacity and redundancies to the Northeastern portion of the system. Main replacement such as this was identified in the original water plan. A failure of this main could impair the Village's ability to supply water to the Northeastern portions of the community and impact traffic on a major expressway. The planned development and increased number of water customers associated with Northbrook Court also increases the needs for this improvement. Currently this main will be replaced with a 20-inch diameter pipe. Additional water model analysis and review will be required prior to final design. Design and completion of this work will require the Village to work with the Illinois Department of Transportation, and the Illinois State Toll Highway Authority. Due to the complexity of the terrain and proximity to Dundee Road, Cook County Forest Preserve, and the Tollway, a Consultant will be contracted to perform the engineering design FY 2026 - FY 2028. The number provided below are estimates of the work that would be required, but still subject to changes and the work is better defined. The project is included in the city 2027 - 2031 Capital Improvement Program (CIP). As of July 13,2026, further details have not yet been identified. *Project information has been obtained through a public capital improvement plan (CIP). A CIP is a financial schedule for short- and long-range projects which is updated regularly. Information listed in the CIP often evolves based on funding availability and the project details, including timeline and value, are subject to change. The content management team will continue to pursue additional details as they become available.
