Meet Michael Bills, Water & Sewer Superintendent for the Village of Oak Park, a Chicago suburb known for, amongst other things, its Frank Lloyd Wright architecture. Michael oversees a 105-mile network of pipes, ensuring 1.7 billion gallons of safe water reach 54,000 residents annually. However, Oak Park was losing 20% of its water-about 530 Olympic-sized pools-through leaks each year.
To address this, Oak Park aimed to reduce water loss to 10%, aligning with Illinois Department of Natural Resources regulations. The challenge was compounded by ageing infrastructure, temperature extremes, and porous soil, making leaks hard to detect.
Oak Park partnered with HWM, a Halma company, using their Fluid Conservation Systems (FCS) technology. Loggers attached to pipes detected the smallest leak sounds, allowing Michael's team to access a digital map of potential leaks and prioritise repairs efficiently.
The pilot program identified 19 previously undetectable leaks, and Oak Park has now expanded the use of FCS’ acoustic loggers across the whole network which identified 10 further leaks within the first month.
