Hiteshji and bullishindian,
Thanks for sharing the links. Both set of links are very good read. It had some fantastic insights on how precious is water, which is running out.
It also makes me feel sad about how our politicians have been eating into our taxes and all other money that they come across. I guess, we hardly have any good politicians seeing a bigger picture of things and take preventive/corrective steps. Especially, Hiteshji's set of links has references to India and our poor waste water management status. It is sad to note that our waste water has been contaminating fresh waters.
People are talking and taking steps like rain water harvesting at residences. But what's the use if such rain water is contaminated by neighbour's waste (crap) pit??! And most of us could only afford a 30X40 site and nothing bigger!
We certainly need stringent building guidelines linked with muncipalities implementing perfect drainage systems and waste water treatment/recycling plants.
