Water is a scarce resource and most of the places in India suffer from Water Scarcity. Rain water harvesting can provide a very natural solution to the water crisis problem and also save you a few bucks.
If you do not believe it, the story if a Bengaluru based scientist will convince you. A.R Shivakumar, who works as a senior scientist at the Karnataka State Council of Science and Technology (KSCST) at Indian Institute of Science (IISc), has been fulfilling his and his family’s water requirements through Rain Water Harvesting only for over 20 years now.
When Mr. Shivkumar started building his house he also the first thing that he focused on was to satisfy the needs of his family without bringing any harm to the environment. He was very meticulous and even went to the extent of conducting a study about the water usage of his neighbors.
According to his calculations the water consumption norms matched with that given by WHO, as per which on an average, 500 liters of water is used by a family of four daily. His next move was examining the rainfall data of Bengaluru for the last 100 years and he was surprised to see that the city had always received enough rainfall, even in those years in which monsoon was less than normal.
He quoted, “I did some calculations and realized that the gap between two good rains is seldom more than 90 to 100 days. So I built a series of RWH tanks that could store almost 45,000 liters of water to tide over these 100-odd days. Also, to ensure that a motor was not needed, I stored the water on the rooftop to avoid it being sent down and pumped up again.”
He has done a comprehensive research on this subject and invented some tools too in order to simplify the process at his home. He has also collaborated with the local departments for making Rain Water Harvesting famous in Bengaluru and made filter equipment to be fitted in tanks. These filters are known as Pop-Up Filter and they have been patented in his name. Shivakumar has also made ‘First Flush Lock and Diverter’ for big buildings and they serve the same purpose as Pop-Up Filter.
The man is so meticulous that he has has even installed solar panels on the rooftop and uses solar energy for lightening purposes and for keeping water hot. His rooftop tank and gardens provide his house cooling further easing his electricity bills.
One man's initiative can change the way water is being used in India. Shivakumar has shown us the way, we need to take inspiration and help our environment by not overburdening it.
