Our agency (City of Sacramento, California) uses leak detection where we listen to specific areas identified to be "problem areas". This effort has been very effective. Approx 95% of leaks discovered using leak detection are on water services Vs Water Mains.

We are in the process of piloting a leak detection system (Echologics) that is deployed on Fire Hydrants. The cellular devices replace one of the hydrant caps and listens for leaks at off peak / usage hours. We are notified if there is a leak heard along with general area. We would deploy staff to correlate leak in the area identified.
