Site work for a water / sewer project in Wilmette, Illinois. Completed plans call for site work for a water / sewer project.

The Water Plant has two raw water intakes: a 33-inch pipe constructed with the original plant in 1933 (approximately 3,000 ft from the shore) and a 42-inch intake (approximately 5,000 ft from the shore) built with the 1971 expansion. The Water Plant utilizes both intakes throughout the year. The 1971 intake is sufficient to meet the capacity demand of the facility. However, if the 1971 intake happens to become unavailable, the 1933 intake is not sufficient to meet the water capacity demand. In 2024, it is proposed to perform a preliminary design study to provide a better budgetary cost. Concurrently, the IEPA loan process would be started to help fund the project. In 2025 through 2027, it is proposed to replace the 1933 intake with a new intake that would be large enough to meet the water demand if the 1971 intake were unavailable and establish a true redundancy in the raw water intake operation. The project also includes the replacement of the zebra mussel control line installed in 1992, the 1971 low lift station isolation valve, and improvements to the low lift pumps. Additionally, it is proposed to install an intake heater to prevent the potential blockage of the intake due to formation of frazil ice. This project is included in the city’s 2024-2033 Capital Improvement Program (CIP). As of March 6, 2024, per owner, consulting services are tentatively scheduled for Spring 2024; no construction associated with this project. *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.
