Sometimes, we do not need to develop wisdom by re-inventing the wheel. For centuries, rain water harvesting has been a dominant activity in our country. Be it for irrigation systems, be it in temples, be it in the backyard of ones own house. This is something that we have always been doing. But, after the concrete jungles have taken over the cities, Rainwater Harvesting has not been in the fore front of demands of any purchaser or builder of home/ apartment in urban landscapes. Do we wake up only after a large scale disaster hits us, like Los Angeles – whose case is explained in the video below?
Rain water harvesting in an urban landscape could be as simple as collecting the water flowing from the terraces out into the road (and causing local street flooding) into an underground tank/ sump or a cachement area which could later used for washing clothes, Cars, cooking, flushing toilets etc. (OR) Letting the rainwater flow into the ground from the terrace through multiple layers of natural filtering like broken bricks etc. which would contribute to the rise of the water tables in the area.
The following two websites have all the resources, case studies, links, community projects and all the necessary information on rainwater harvesting – particularly in India.
The following video is actually an advertisement for the rain water harvesting systems but has a lot of information on practical implementation of rain water harvesting. As they say, some times the advertisements are more informative and useful than the programs/serials in our television.
And if you have watched all the videos till now, do watch this one also. A nice way of putting across the message. Just to end.
Do let know if you know of any interesting implementations of the rain water harvesting methods in your area.
