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

A village school in Madhya Pradesh deals with the micro-realities of the area and gets out of a sanitation crisis.

Sajan, a 14 year old Bhilala Adivasi boy studying in the Rani Kajal school in Kakrana in Alirajpur district of Madhya Pradesh says, "We now save a lot of time as we bathe in the bathrooms and defecate in the toilets rather than in the open fields; and so we study better". The school on the banks of the River Narmada run by the Kalpantar Shikshan Kendra, now has functional bathrooms and toilets which is an exception in this country as despite the hype around the Swachh Bharat campaign, the reality is that most schools are without functional toilets.

Hi

I read the article you published on rain water harvesting as I was looking to find more information about it. I am interested in installing it for my home and open farm land, but I am not sure whom to contact. The article would have been much more useful if it had referenced the following points:

  1. Whom should I contact to install the system for my home/open farm land
  2. Recommendation on quality products
  3. Contact information of companies that sell and install the system

Please advise.

Thanks Sudha,

The film “Rainwater Harvesting: From books to fields”, showcases how rooftop rainwater harvesting can also bring about social and economic change.

Chhattisgarh ranked number 1 in the country for providing domestic water connections in 2014-15 under the National Rural Drinking Water Programme (NRDWP). Despite this, the government has failed to provide safe and clean drinking water to many who are still affected by fluoride, arsenic and iron contamination.

Hundreds of villagers pitched in to revive a village pond at Bapugaon, a village in Rajasthan, to make it water and food secure.

It had not rained for awhile and the tiny cracks in the earth in Bapugaon were opening up. This little village in Chaksu tehsil of Jaipur was yet again faced with a drought in the mid 1980s. The situation was aggravated in 1986 when the river Dhund, an important water source for Bapugaon, went dry. Since then, both the quantity and quality of water started deteriorating. The rains were playing truant yet again and had stopped buffing up the rocks and big boulders scattered over the hills.

Taankas are trusted allies in the harsh weather of Rajasthan, but the focus is shifting now onto personal assets rather than community resources.

We were driving down the long desert road that runs parallel to the Indo-Pakistan border in Jaisalmer, Rajasthan. There was little else to see except the surrounding sand dunes and desert grass. That's where I saw a ‘taanka--a raised platform with a small opening to fetch water from its womb--for the first time.

How can the massive quantities of rain falling during the four-month monsoon period be stored so that it can be used over the entire year in the Hindu Kush Himalayan region?

The Hindu Kush Himalayan region (HKH) is the source of 10 major rivers and is often referred to as the water tower of Asia. However, communities living in this region and downstream face frequent seasonal water scarcity and flooding due to high variations in rainfall. This causes too much water in the wet season resulting in floods and other natural disasters, and too little rain in the dry season resulting in droughts and crop failure.
