The Public Works Department’s Water & Sewer Division is responsible for maintaining Oak Park’s aging 105-mile network of pipes that deliver 1.7 billion gallons of safe, drinkable water to residents each year.
In recent years 20% of the treated water the Village purchases from the city of Chicago was lost through leaks, in part because some infrastructure dates to the late 19th century. Village officials set the goal of reducing the water loss, but faced challenges given that leaks are difficult to spot.
To address the problem, the Village recently launched a project to install environmental monitoring technologies that can listen for leaks in the network.
As of last summer, 545 sensors called loggers were placed throughout Oak Park’s water network, attached to pipes with magnets. These loggers pick up the smallest sounds made by water leaks. As soon as the tell-tale noise of a water leak – similar to the sound of a flute – is detected, the sensor converts it into a digital signal and alerts the system.
From there, Village staff can access a digital map of all possible water leaks, helping prioritize what needs to be fixed, ensuring that resources are deployed effectively.
