“Water, water everywhere but not a drop to drink”


Rainwater harvesting a presentation

This could soon be true in India as most of the cities face a water crisis today due to irregular rainfall, a growing population and rapid urban development.

Excessive ground water usage has led to a sharp decline in the ground water levels across India prompting the government to pass strict regulations against the usage of the same.

However, the fact is that ground water is essential both residential as well as industrial projects.

So how does one more ground water ?.


The solution

The solution

The solution is Rainwater Harvesting.

Rainwater Harvesting simply put is the direct collection of rain water. The idea is to catch the rain as it falls over building & ground surfaces and channel it to pre-defined recharge points after filtration.

This helps recharge the groundwater levels which is a long term solution for increasing our ground water levels.

Today, there are solutions also available which help harvest rainwater and filter it for non-potable immediate usage.
