Yes, its raining non-stop for weeks in chennai, and many parts of India. But coming to chennai, which is one of those cities having a ground water depletion problem, rains mean solution to water problems to some extent at least temporarily.

Many indian cities and villages now largely practise the idea of rain water harvesting.. thereby recycling rain water otherwise wasted as stagnant water in buildings, back to the source well or the ground if no well is present.

But is this enough?
Definitely a no. Rain water harvesting has to be insisted into road-laying, rail tracks, airports, drainage/sewage flow mechanisms, etc., to make use of 90% of that rain water flowing outside the buildings on the roads, and the ground.

The rains currently in chennai have had all present storage dams and reservoirs full which will help supply needs for another 3 months, but after that nothing.

Do we need to store more beyond this?
A definite yes, water being the major resource needed in many activities and even for developing the infrastructure to store water.

But, the Good news is,
For now, chennai is better off on its water crisis.
