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

Hello,

I am planning to harvest rooftop rainwater and use it for groundwater recharge through a recharge borewell. To begin with, I've not been able to get any data on geology below the site from the owner of the place and also the government.

My queries are:

A visit to Oddoor farms near Mangalore, Karnataka, provides an inspiring example of the efforts made by Rajesh Naik ji to transform 120 acres of barren land into a lush green farm.

A visit to Oddoor farms near Mangalore, Karnataka, provides an inspiring example of the efforts made by Rajesh Naik ji to transform 120 acres of barren land into a lush green farm through his persistent efforts of creating a two acre and fifty feet deep lake, which has not only transformed the surrounding area, but has also helped in improving the water table in the surrounding village, besides helping in the development of a self sufficient organic farm and a dairy.

Oddoor farms, around 25 kilometres away from Mangalore city is a great example of a very successful effort made by Rajesh Naik ji who has transformed 120 acres of barren land into a self sufficient organic farm by developing a 50 feet lake on two acres of land.  The journey has been a long one and not without its share of challenges, but persistence and constant optimism and hard work to overcome challenges has reaped results in the last twenty years, informs Rajesh Naik ji.

Query received through email from Kiran Chainani

Hello,

We are constructing a house in RMV extension in Bangalore, the construction is yet to begin. The water table in the area is very low and am concerned about the availability of water.  Although we do have a borewell, I would prefer not to use it if at all that is possible.

The area gets piped water supply once in three days. I am looking at ways to make the house as self sustaining as much possible vis-a-vis water. In addition to rainwater harvesting, am thinking of grey water recycling.

In this article, we look at the efficacy of this programme at providing water security. This article is based on discussions at the IWMI-Tata Annual Partners' Meet in 2012.

A month ago, India Water Portal tried to make sense of the numbers involved in India's flagship programme. Two-thirds of the works in progress in the current financial year (2012-13) were devoted to works linked with water - split nearly equally between water for domestic use and water for livelihoods.

I am staying in an apartment and the existing bore well is yielding less compared to earlier days. When it rains we have made provision to collect the water in the premises.

Need technical support/suggestions to channelize the rain water to the existing borewell and recharge it.

Kerala is a rain blessed state in the country, but due to its slanting topography there is significant decline in the ground water levels leading to severe water scarcity. This paper sheds light on groundwater quality issues in two panchayats of Kerala

Kerala is a rain blessed state in the country. It has highest  number of wells, when compared with other states. However due to its slanting topography there is significant decline in the ground water levels leading to severe water scarcity during summer months in most districts of the state. Further over extraction and dependence of groundwater for domestic use from the dug wells especially in rural pockets has resulted in several groundwater problems. In this backdrop the paper in  The Ecosan- An International Quarterly Journal of Environmental Science, sheds light on groundwater quality issues in two panchayats of Kerala.
