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

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

Rainwater harvesting is a cost effective solution to bridge the gap between water availability and demand. Jodhpur and Goa, areas with low and high rainfall, have shown how.

As the race to bridge the gap between limited water availability and increasing demand for water narrows in India, rain water harvesting has been increasingly recommended in urban areas to harness the available water, rather than relying on expensive and unsustainable means of procuring water.

Eris or tanks in Tamil Nadu, which once provided water for drinking and irrigation, are in disrepair today. Can technology help restore them?

Several lakhs of farming communities in Tamil Nadu depend on the 39,202 tanks spread around the state. These tanks capture the runoff water from the monsoon rainfall that occurs in a short span of time, and also provide water for irrigation and other uses for the community.

However, these water bodies have been degenerating in the recent past due to reasons such as:
