The fact that water is even being debated as a commodity or a human right itself scares me... and to know in the next 50 years we'll have to desalinate sea water because fresh water supply will get thinner and thinner is scarier still....
Why are we getting so unconcious of what is right or wrong?
Is everybody deliberately using up water resources?
Are we all over using water?
I am still learning and dont have all the answers yet but spreading awareness is something I must do.
Did you know that Rain water is one of the purest form of water you could have? (that's only in the case you dont live in an industrial area)
Did you know that for a 1000 sqft roof top area, or 100 square meter roof top, (which is the area of the roof of a small 30x40 house in bangalore) in bangalore you could harvest as much as 90,000 litres of water in a year?
And this is 1/3rd of the water a family of 4-5 would need in a year?
If all of us began harvesting rain water it would ease off the pressure on the rivers that are being fought for.
The method to use Rain water is so simple, its unbelievable. All you need to do is slope all the water on your terrace in one direction and collect it into this tank (either made from ferro-cement or a small PVC tank would do), let the water filter through natural materials like thin fabric, sand and coal, and let it all go into the underground sump you have for water storage!
All overflow could simply go into a well (about 2.5-3 feet dia and 20 feet deep) and that would help keep the ground water level good. The sub-soil water level is important as the surface water supply is soon running dry.
Sometimes we are too selfish and careless and if the carelessness continues it could cost us a lot. Dont cement all sides of the property...leave ground/earth in places so that water can seep into the earth below.

The technique is so simple that everyone can do it. There exist a lot of misnomers about RWH and I simply wanted to change them.
Alas if all apartments and large buildings alongwith all the many residences that are mushrooming all over the city began to store water from the rain... there would be less fights over rivers in time!
If you want to know what to do Mr.Vishwanath and team are willing to teach you and guide you for free. Anyone is welcome to go visit and see the techinques they're using for the same in their house.
I just hope more people begin harvesting rain water and become a little more careful in the way they use water and other resources without making it a burden for themselves.
