Renovation of a water / sewer project in Wilmette, Illinois. Conceptual plans call for the renovation of a water / sewer project.

Filter Valves Replacement Each filter at the Water Plant has 5 valves: • Influent valve to allow the water into the unit. • Drain valve to drain the backwash water away from the unit. • Backwash valve to allow the water from underneath the filter unit during the backwash sequence. • Surface wash or air scour valve to assist during the backwash sequence. • Effluent valve to allow the filtered water to move into the clear-wells. A typical butterfly valve could last for 35-45 years before replacement. In recent years, staff has noted increased difficulty operating the valves and some leakage. Due to their age, there are no repair parts available for these valves and they will require replacement. At the same time these valves are replaced they will receive motorized operators. Motorized operators provide added longevity and improved SCADA compatibility over the current cylinder actuated operators. Some valves were replaced in 2013. 2026 Project High Lift Flow Meter Vault “A” Replacement The existing Vault “A” flow meter, installed in 1956, is used to measure high lift pump flows entering the distribution system. It is one of two high lift meters. 2027 Project Flocculation Basins 1&2 Valves Replacement Basins 1 and 2 are currently operated in series, as one combined basin. During the stress testing conducted in 2004, treatment deficiencies (high settled turbidity and poorly coagulated water) were identified in this basin pair. A preliminary engineering review suggested that if the Village restored these basins to their original operation as two separate basins, this would likely solve these deficiencies. This will be accomplished by replacing two of the inoperable 1933 gate valves and installing a blank plate over a third broken valve. The project is included in the City's 2026-2035 Capital Improvement Program (CIP). As of January 31, 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.
