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

In this article, Seetha Gopalakrishnan introduces us to the Rain Centre and it activities in Chennai with respect to storm water construction in the city

One of the most conspicuous activities in the preparation for the monsoons in several cities today is dug up roads ! Crores and crores are spent on the construction of storm water drains alongside roads in cities and towns to prevent flooding during the rains. These channels / tunnels, that stretch for several kilometers, winding its way across the city, are expected to channel all the collected water into the nearest water body, say a lake or a river.

I am trying to do some work before this monsoon to make villages self sufficient in the water requirements.

In Aurangabad (Maharashtra) the average rainfall of the year is approx 600mm, even if we get 50% of it we will have 300 mm of rain. This is quite sufficient amount of rain to have water throughout the year. But in this area many villages are dependant on tanker water, and it is started already from now.

We have 7 months ahead to work, need help for the same. Trying to gather people who are interestd in this subject.

I was looking for consultants who can review the water facilities, consumption and RWH implementation in our apartment complex and give us some suggestions and best practices. The reason being every time we have a shortage, the community speaks of having another borewell and some of us don't believe that maybe the right solution.

It would be of help to have contacts with whom I could follow up with over e-mail /call .

Thanks,
Megha

In the times when tapped water supply is considered an absolute sign of development, the traditional water harvesting systems are losing their age-old relevance. This is why the Lakholaav pond in Rajasthan assumes greater significance. Located at Marwar Mundwa town in Nagaur district, Lakholaav is an exception. As ponds in other towns have shrunk due to encroachments and dumping of garbage, Lakholaav is providing drinking water to the town the whole year round. Citizens as well as the municipal committee take utmost care ensuring cleanliness and efficient management.

“According to a folk tale, the pond was developed by Lakha Banjara, a nomad trader whose tribe used to stay put in the area on its way to bigger cities. Since water is not easily available in Rajasthan, nomadic tribes like that of Lakha Banjara used to dig such ponds on their travel routes, which could also be used by the locals,” says Girdhari Singh, who belongs to Mundwa and works with community on traditional water harvesting techniques in Jaisalmer district.
