Rainwater Harvesting

Rainwater harvesting (RWH) is a simple method by which rainfall is collected for future usage. The collected rainwater may be stored, utilised in different ways or directly used for recharge purposes. With depleting groundwater levels and fluctuating climate conditions, RWH can go a long way to help mitigate these effects. Capturing the rainwater can help recharge local aquifers, reduce urban flooding and most importantly ensure water availability in water-scarce zones. Though the term seems to have picked up greater visibility in the last few years, it was, and is even today, a traditional practice followed in rural India. Some ancient rainwater harvesting methods followed in India include madakas, ahar pynes, surangas, taankas and many more.

This water conservation method can be easily practiced in individual homes, apartments, parks, offices and temples too, across the world. Farmers have recharged their dry borewells, created water banks in drought areas, greened their farms, increased sustainability of their water resources and even created a river. Technical know how for the rooftop RWH with direct storage can be availed for better implementation. RWH An effective method in water scarce times, it is also an easily doable practice. Practical advice is available in books written by Indukanth Ragade & Shree Padre, talks by Anupam Mishra and other easy to follow fun ways

How can the massive quantities of rain falling during the four-month monsoon period be stored so that it can be used over the entire year in the Hindu Kush Himalayan region?

The Hindu Kush Himalayan region (HKH) is the source of 10 major rivers and is often referred to as the water tower of Asia. However, communities living in this region and downstream face frequent seasonal water scarcity and flooding due to high variations in rainfall. This causes too much water in the wet season resulting in floods and other natural disasters, and too little rain in the dry season resulting in droughts and crop failure.

It isn't just the tourists or its hilly terrain but a 140 year old leaking water distribution system set up by the British in 1875, which is leading to heavy losses and contamination.

Most tourists visiting Shimla won’t know that they are walking on a water tank when they wait to get their pictures taken or go horse riding on Ridge road but they will know that the city faces water shortage -- their hotel bathrooms have messages asking them to use water judiciously.

Dear India Water Portal,

We cultivate rain water from roof top with first rain flush theory. We also allow ample flush for secondary and third rain depending on quality of rain. We are using filtered rain water for daily drinking purpose.We have also installed a membrane based filter prior to drinking. We would like to understand what parameters should be followed while considering rain water for drinking ?

Thank you
