Pathetic Water Situation in Andhra Pradesh, India

Few years ago I took a picture (on the left) of a bird in summer in New Mexico, USA. Recently I have seen a picture (on right) in one of the main news paper Eenadu of Andhra Pradesh, India. It is such a heart wrenching scene to see some body having to drink water from the road like this.

I am doing some research to see how I can use rain water harvesting in Andhra Pradesh. I hope I find something economical and implementable on a small scale. If anyone comes around a plan which a single individual can implement efficiently for a small family and is scalable, do leave a comment.
