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

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).

The city's old wells and baodis are running dry, and the Yamuna is getting more polluted by the day. Where is Delhi's water going to come from when groundwater levels are also dropping?

Delhi, home to 16.75 million people, is in the grip of a major water crisis. Statistics by the Delhi Jal Board for the year 2011 suggest that the water deficit stands at about 250 million gallons per day with the supply being 830 million gallons per day. Unaccounted for water--the gap between the water produced and distributed--is as high as 40-45%.

Rice-fish systems allow for the production of fish and other aquatic animals as well as rice from the same rice field area, and generally without causing reductions in rice yields.

Coastal regions of Kendrapara and Jagatsinghpur districts of Odisha have been hit by cyclonic storms for more than two decades. These have severely affected the livelihood of the communities living in the region. Ashok Das of Junapangara village is one such farmer who had suffered massive agricultural losses. He owned around two acres of land, including homestead land, with a pond. With a wife, two daughters and a son to support, he gave up agriculture in 2011 and took up the job of a labourer.

Hi,

I am building a house on 30x40 plot in Bangalore. I have made the provision for storing rain water which is approximately 30,000 liters. I want to harvest the grey water as well. I want to reuse only the water from the kitchen and washing machine. We are a family of 4 including a 3 years old kid. Is it worth considering grey water harvesting? If yes, what is the storage capacity required? What should happen when the grey storage tank overflows? Can someone please send me the design?

Thanks, Shishir Thalner
