Its Raining in Chennai.

There has been a heavy downpour of rain in the last few day. The latest rain in Chennai's catchment has gladdened the city water managers as this has resulted in the much need flow into the reservoirs, though in a modest way. Consequently, the combined storage of the reservoirs catering to the city needs went up by 30 million cubic feet.
The authorities are confident of maintaining the present level of 640 million liters a day(MLD) in the coming months as Krishna water is also expected to be available next month.

So it is anticipated that there would not be any drinking water problem in Chennai for the next 1 year
