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

Nanduwali in east Rajasthan started flowing again when the villagers decided to work with nature and not against it. The river is now lifeline to those settled on her banks

Gajanand Sharma is excited about the monsoon this year. He is building an anicut on the small stream that runs through his farm. “After the rain, the land will be filled with water and then I will sow wheat and reap record production in this area,” he prophesises. This forecast doesn’t come from his knowledge of astrology, but that of geology, gained over the years.

Data shows Haryana has done better than its parent state, but the positives are getting lost as both states clamour for more.

Rapid growth in population, agriculture production, industrialisation and urbanisation have put an extreme burden on India's dwindling water resources. Water-guzzling paddy covers maximum gross area under cultivation at 44 million hectares. Disputes related to inter-state rivers have been rising be it the Cauvery in the south or the Yamuna in the north.

Hello

Rainwater should go to underground with the help of small pipes in urban area roads. Is this possible ?

We stay in a small galli where a lot of rainwater accumulates during the rain and and then simply evaporates. Can we send it for groundwater recharge? Is it only possible for newly constructed roads? Can the existing roads also use any possibilty to recharge groundwater?

Thanks

Yogita

Hello,

I have a roof top terrace garden that I have tended to for many months now. I don't use any chemicals for the plants and the only addition to the soil is compost once in a few months. Is it okay to harvest rain water from the same place where I have this garden?

I was adviced by one person that i should clear the terrace space if i want to harvest water from there. Is that so and are there any other ways to do this (any creative designs/ filters that can take care of the garden contamination?)

Thanks

Technologies are magic, and Israel has been creating such magic since 1964. India Water Portal speaks to Uri Schor, the Spokesman of the Israeli Water Authority to understand this.

The Israeli water industry is one of the best in the world, and this is because of the country’s breakthrough in technological innovations in areas like desalination, drip irrigation and water security. The country uses its water so sustainably that since 1964, its total water consumption has remained nearly the same in spite of a growing population and increased agriculture.

Hello 

I need some help to design a filter for roof top rain water harvesting. The water catching area is 100 sqm, and the rainfall maximum is 130 mm, and so the filter should have the capacity to filter 216 liters/min. I have a 4'' down pipe installed, while the storage area is a live well 52 feet deep . This water will be used for cooking too.
