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

As part of the Village's Water Fund review, the Village instituted a water main replacement program with the focus of replacing 1.5 miles of water main annually. The program's focus is to replace 6-inch cast iron main within the water distribution system, as this main is historically the worst performing classification of main in the distribution system. The water main in the Northbrook Highlands and Kiest's Subdivisions have been scheduled for replacement due to their age and overall condition. Staff anticipates that contractual engineering design for this project will occur in FY 2029 with construction to occur in FY 2030. The replacement of these mains will be coordinated with the asphalt street rehabilitation program occurring in the same area in FY 2030. 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).
