Great idea and this is something I have been wondering about for many years. How come a country with such a rainfall can have such an acute water shortage. I think it would be a great idea to have a dual purpose roof top devices which would collect rain water and solar energy at the same time. This is ideal for Bangalore type of city where people live in sites and houses with their own open sky. BTW the www.rainwater.org is a website from TX, US. May be actual website should be www.rainwaterharvesting.org.
