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

Karnataka, especially Bengaluru, is facing severe water crisis this summer. Rainwater harvesting is the way forward, believe experts.

The next big war is said to be for water and it might happen sooner than we think. If the current water scenario across Karnataka and most parts of India is anything to go by, we might just be the generation to start this war. 

The situation in several parts of Karnataka is a dismal one, to put it mildly. The intense heat coupled with inadequate to no water at all leaves us dreading the long harsh summer that is ahead of us. Without water, life simply comes to a standstill. And it has, for many.

I belong to Roorkee and i would like to find information regarding organisations working in rain water harvesting field in Uttarakhand. I want to develop a home based rain water harvesting system which can be used to quickly store rain water, maybe used for rejuvenating the underground water instead of collecting on the streets. There is a lot of talk about India promoting rain water harvesting but it is hard to find an organisation to do the work.

United Breweries commits to conserving water on World Water Day

Water is the most precious natural resource available to mankind. We can survive without food for days, but not without water. The availability of fresh water has been taken for granted for centuries. The world’s population has grown from 1.7 billion to 7.5 billion in the last 100 years.

The revival of Narayanapuram wetland is a fitting example that good things can come out of government’s willingness to associate with independent organisations for the betterment of the society.

Once home to over 400 water bodies, Chennai’s development story is similar to most metropolises across India. Urbanising at a hurried pace, the concrete city spilled over its waterways and wetlands, leaving behind a sorry tale of ecological destruction. The Narayanapuram wetland, part of the massive Pallikaranai marshland, which was recently taken up for restoration, shows that not all hope is lost; not yet, at least.

The residents of Yavatmal come together to solve their drinking water problem. With crowdfunding to aid their effort, the result is inspiring.

Located 10 km from the Yavatmal city in Maharashtra, the Nilona reservoir has been the primary drinking water source for its residents since 1972. As in many other parts of the country, the 1990s saw the city growing and the population increasing. The Yavatmal residents, who had not experienced water shortage till then, started facing acute drinking water shortage. Rubbing salt in their wounds were the authorities who cut the household water supply to half--from 64 million litres to 32 million litres weekly--in 2014.

How the Doha model of groundwater recharge saved the livelihoods of farmers in Maharashtra.

There was a time when the farmers of Yavatmal district depended completely on rainfed agriculture. That was before the introduction of Doha, a water harvesting structure by NGO Dilasa Sansthan in 2014. Farming changed drastically after that, something which Sitaram Kove, a 40-year-old farmer of Rajini village in the district, will vouch for. Once a distressed farmer like many in Vidarbha and Marathwada, he is now content with the productivity of his six-acre-farm that has doubled since the introduction of Doha.

Tamil Nadu continues to witness cycles of flood and drought annually. Mismanagement of traditional water management systems is one of the main reasons.

That Tamil Nadu qualifies to be dubbed as a land of climate paradoxes is beyond debate. The massive flood of 2015 was quickly followed by a punishing drought in 2016. Though the state benefited marginally from the south-west monsoon, as is usually the case, the biggest let down was the manner in which the more dominant north-east monsoon had panned out. Tamil Nadu wound up with a paltry 168.3 mm of rainfall during the north-east monsoon season as against the normal 440.4 mm, leaving the state with an overall deficit of close to 62 percent of the long-term expected average precipitation.
