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

This article provides references to the preservation of the environment in the Rigveda

आधुनिक विज्ञा के अनुसार सृष्टि के आरम्भ ,में पृथ्वी पर ओज़ोन आवरण नही था. धीरे धीरे जबय्ह आवरण बना तब इस के पश्चात हीपृथ्वी पर जीवन सम्भव हो सका. इस आवरण कोबनाए रखने के लिए वन सम्पदा पेड़ों इत्यादि का सब से महत्व पूर्ण दायित्व है. आश्चर्य होगा कि इस बात को ऋग्वेद में राजा के प्रजा के कर्तव्यों में प्राथमिकता दे कर कैसे बताया है. कृपया स्वयं देखिये.(यह लेख मैंने अंग्रेज़ी मे लिखा था)

We have two months of monsoon left and 4 months of returning (North East) monsoon to conserve water

Remember, Water harvesting Principles:
Make the running water to walk, walking water to crawl, crawling water to stay and sink

“Catch the water in the hills during 4 months of monsoon, Store the water in rivers and river lets during next 4 months, Summer 4 months will have enough water”
-Shree Padre

This applies to both coastal as well as mainland regions.

I am residing in Vijayanagar in Bangalore. We are five member family, and our average consumption of water per day is around 700 to 800 lts. Since a good number of borewells were dug in Vijayanagar, I was also tempted to get one for our home considering the water scarcity during this summer. We have a sump of 5000 lts capacity and also have some area for constructing one more sump of the same capacity.
