Highlights of the report are:
- The north Indian states of Rajasthan, Punjab and Haryana are the worst affected with groundwater levels reducing at the rate of one metre every three years (one foot per year).
- Ground water is pumped and consumed rapidly due to:
- population explosion
- rapid economic development
- water-hungry farms
- When groundwater is rapidly consumed, recharge to the original levels by natural process can take months or years.
- If corrective actions are not taken, it may lead to famine due to collapse of agricultural output and severe potable water scarcity.

One of the easiest way to recharge ground water is by implementing Rain Water Harvesting (RWH) in all
- Residences with any type of roof
- Shopping complex, railway stations, bus terminals, government buildings, schools, flyovers including temples, churches, mosques etc.,
Here is a recent advertisement in leading newspapers by Chennai Metro water on RWH. Also here are different types of RWH recommended by them.
In our apartment after implementing rain water harvesting, we are not facing any ground water shortage.
