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

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.

Women are not only responsible for water but they also face the brunt of water scarcity. Watch the video to find out what happens when these women become 'Jal Sahelis' (water friends).

Sirkoo, a 39 year old woman in Bundelkhand, Uttar Pradesh, walked 8 km every day to fetch water. As a woman, it was obviously her responsibility to ensure the household's water availability. This put an additional stress on her already depleted health as well as time--until she decided to tackle the issue head on.

Simon Oraon, leading a people’s movement to save water and forests in Ranchi, Jharkhand

It was 1961. Simon Oraon, a Class IV school drop-out began his journey against drought in Bedo, a tribal block of Ranchi, Jharkhand. An idealistic young man, he along with his fellow villagers began constructing earthen dams to capture rainwater for recharging groundwater. This along with his broader work on self-initiated environmental and forest protection systems provided a tipping point that rejuvenated the forests and brought the wells and surface water bodies back to life.

While the monster floods of 2015 mercilessly gobbled up villages along the coast of Tamil Nadu, settlements in neighbouring Puducherry managed to escape the fury. Miracle, you say?

The East Coast of India is very much unlike its western counterpart both in terms of physiography and climatology. Unlike the West Coast which receives a predictable amount of rainfall within a predictable time frame, the East Coast is entirely dependent on the depressions in the Bay of Bengal to bring in the much needed rain. Due to the absence of a set pattern and the erratic nature of rainfall, the engineers of ancient times came up with a fool-proof solution – constructing tanks to hold the water.

Farmers have been known to observe the movement of ants and butterflies to forecast rainfall. Do such indigenous practices hold the key to addressing climate change issues?

Erratic rainfall, heavy storms, extreme weather and droughts are some of the major impacts of climate changes. Though it affects everyone, certain sections of society, like indigenous people who live closer to the natural environment, are in fact more vulnerable to these variations. However, they are also the first to observe, identify and formulate required strategies to adapt to climate change. This wisdom, insight and knowledge of local people is termed as indigenous technical knowledge (ITK).
