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

There are many unsung heroes amidst us who go about their good work silently. Chattar Singh is one such hero who has revived traditional water management system of the parched Jaisalmer villages.

“Can you see the alternating bands of light and shadow in the sky?” Chattar Singh asks me. When I nod in affirmation, he continues, “This is Mogh. There are clouds where the sun is setting right now. If we get a favourable wind, these clouds will reach here and we may get rain by night. In desert, people live by such clues from nature.”

Despite all the hype around Swachh Bharat Mission, the situation on the ground remains abysmal. The city of Ujjain is located on the western part of Madhya Pradesh on the Malwa Plateau and is primarily a religious tourism centre due to the Mahakal temple. The temple is not only one of the 12 jyotirlingas in India but also has prominence as the location for the Simhastha Kumbh Mela every 12 years.

One of the temple ponds of Kooram, neglected for years, has been revived by well-meaning citizens.

For hundreds of years, tanks, both big and small, served people and cattle alike in Tamil Nadu. Chennai’s neighbouring district of Kancheepuram was the the wealthiest when it came to water through these means. The Chola and Pallava kings, along with various other major and minor royal houses of the time, dug out massive irrigation tanks or eris, as they are known locally, to support agriculture in a terrain fed by seasonal rains.

Hello

I live in Bhimtal, Uttarakhand. We are in process of finalizing a design for our cafe. Since we are constructing afresh, we would like to do it right and imbibe a rainwater harvesting system in the construction. The architect has been chosen and the final capacity will depend on the area of construction. It rains 1670mm annually, on an average.

I would like to know if there is a provision of subsidy from the government for installing rainwater harvesting in the property; and how to go about applying for it.

Regards

Akanksha Bumb

Hello

There is filter from my terrace to an open well for RWH. My terrace also holds my vegetable garden. The organic fertilizers from the garden can make the water impure, and I have been advised to remove the vegetable garden from my terrace. However, I want terrace vegetable garden and rainwater harvesting go hand in hand. Could you share some expert advise on this?

Thanks

Citizens come forward to restore polluted lakes and rivers in their cities. They demand support and swift action from the government.

The pitiful state of some of the water bodies in the country, coupled with the sheer apathy of the government, have forced some well-meaning citizens to come out of their comfort zones and make a difference. Some of these efforts, like the Puttenahalli lake in Bengaluru that is now overflowing with clean water, have been successful, while others are ongoing. Here, we feature some stories of a few Good Samaritans and their efforts to restore the lakes and rivers of their cities.
