Water ranges are operating desperately low, significantly in poorer areas, leading to sky-high prices for water and a shortly dwindling provide.
Metropolis and state authorities authorities try to get the scenario beneath management with emergency measures akin to nationalizing water tankers and placing a cap on water prices. However water consultants and plenty of residents worry the worst continues to be to return in April and Could when the summer time solar is at its strongest.
The disaster was a very long time coming, stated Shashank Palur, a Bengaluru-based hydrologist with the suppose tank Water, Setting, Land and Livelihood Labs.

“Proper now, everyone seems to be drilling borewells in buffer zones of lakes. That’s not the answer,” Ramachandra stated.
He stated town ought to as a substitute give attention to replenishing the over 200 lakes unfold throughout town, cease new development on lake areas, encourage rainwater harvesting and improve inexperienced cowl throughout town.
“Provided that we do that will we clear up town’s water drawback,” he stated.
