  • How does GIS for Water Leak Detection Work? - The Water

    The sooner the leakage is detected, the less clean water will go to waste. Water loss is something that can be prevented if the leakage is detected in time and if it is rapidly fixed. The problem with detection is that only bigger leaks get detected, often even they get noticed and reported after the pipe bursts.
