This pilot was undertaken with the aim of supporting the city to reduce the excessive wastage of water from the leaks by pinpointing the leak even before a puddle is formed on the surface. Two acoustic leak detection machines have been provided to the Siliguri Municipal Corporation through the project. Training in the use of the same has been provided to engineers and officials of Siliguri Municipal Corporation. As a pilot study, these machines have been used to conduct a water audit in water zone 1 of the city.
