Title
A Resolution Approving an Independent Contractor Agreement with Midwest Meters, Inc. for the Village-Wide Water Distribution Leak Detection System in an Amount Not to Exceed $622,390.00 and Authorizing its Execution
End
Overview
Overview
The proposed agreement is for a Village-wide sensor-based leak detection system. These devices are intended to aid Village staff in the discovery of water distribution system leaks that do not come to surface and are not discoverable with current surface leak detection practices. The Village started a pilot program in April 2023 and confirmed that these devices are effective in finding non-surfacing leaks. To date, the pilot program has detected 19 leaks that would have gone undiscovered until surfacing in a little less than one-third of the Village. Staff recommends expanding the pilot program to a full-scale implementation across the entire Village system.

Adopt the Resolution.
Background
The Illinois Lake Michigan Water Allocation Program was developed to manage Illinois' diversion of water from Lake Michigan; all diversions of water from Lake Michigan require authorization in the way of an allocation permit from the Illinois Department of Natural Resources (IDNR). All permittees, which includes the Village of Oak Park, are required to submit an annual water audit form (LMO-2). The LMO-2 details the amount of water used, sold, and lost by a permittee. The IDNR's ever-decreasing Non-Revenue Water (NRW) threshold, currently, is ten percent.
The Village's five-year running annual average for NRW is 23.9%. Village staff recognize that one of the main contributors to high NRW is distribution system leaks. A proportion of these leaks are small chronic leaks that may never surface and are undetectable with current acoustic leak detection surveys.
