The Water Bodies around the world are drying up in an increased number which is being mainly caused by Global Warming and some other reasons, Icebergs are melting freshwater bodies especially aquifers are getting exhausted. The oceans cover 71 percent of the Earth’s surface and contain 97 percent of the Earth’s water. Less than 1 percent of the Earth’s water is freshwater, and 2-3 percent is contained in glaciers and ice caps. This year we are observing the Chennai water crisis caused by the upturn in the scarcity of water and amidst these tough times, we see a civil engineer from Chennai creating an Rs.250 water harvesting system.
Dayanand Krishnan, a 45-year-old civil engineer from Chennai who invented a cheap innovation in rainwater harvesting that helped him save over 200 liters of water in just 10 entire minutes. The Cost of this water harvesting system made by Krishnan was only Rs 250. Krishnan says that his system requires no plumbers or experts to be installed. It can be done at home by anyone.
“Thousands of liters of water was just going waste even as Tamil Nadu is struggling with severe water shortage. That was my cue to do something in my personal capacity to save freshwater,” says the enterprising civil engineer.
The components used by Krishnan in the making of this system were, a drum which he already possessed, a three-feet PVC pipe, two pipe bends and a cloth filter which he had to buy. His terrace, spreading over 400 square feet, was the collection point to which the pipes were attached. The other end of the pipe was directed to the drum, secured with the cloth filter.
“Every terrace and most balconies have an exit pipe attached to them that directs the water out. My trick was only to secure the end of these pipes and get them to collect water in the drums. I put a cloth filter for obvious reasons. When Chennai welcomed the heavy rainfalls on 26 June, the rainwater harvesting system did its job. We purchase water tankers for about Rs 1500 and considering the situation Chennai is in, the tanker arrives a couple of days after we’ve ordered it,” says the 45-year-old. “With my rainwater harvesting system, I can take care of most of my water needs for 2-3 days following rainfall. If you need more water, add another drum to the system. It’s as simple as that.”
The System is commendable, easy to use and most importantly cheap.
