They are not going to run out of water. I was born and raised in Bangalore, Have been in places around Bangalore all life. And water struggles have been forever.
Bangalore has water infrastructure problems, not water shortages. We will fix them in time, like we always have.
I have to agree. The problem is not rainfall. There is plenty of water. Indeed it is expected that global warming will result in greater rainfall not less. The problem is infrastructure. That is a matter of time and money. It will get solved.
