With peak summer approaching, Bengaluru is already facing a water crisis. The city, which is dependent on the Cauvery river and groundwater for its freshwater needs, remains vulnerable to drought in the dry seasons and flooding in the monsoon months. With its bore wells having to contend with receding water tables, and tankers having to travel increasingly longer distances to fetch water, there is a big question mark over the city’s water security.
