having toilet at every house might not be a good option... recently a villager told me that earlier they had home made khana (food)because system of defecation was outside of home, but now system of ready made food is getting more popular because we have toilet inside our home..
All rural Indian can afford a Toilet and they like to use closed system of sanitation.But there is no WATER to clean.There is acute shortage of clean and safe Drinking Water in most part of rural India.Kindly provide them PIPE DRINKING WATER and their change in ATTITUDE will follow, Ghanashyam Pandurang Vaidya.
Lets do some math. 1250 million people. 1 number2 per day. 3-4 number1 per day. Amount of water needed per flush 8 litres. total no of flushes required = 1250x4 = 5000 million total water reqd per day is 5000x8=40000 million litres = 40 billion litres. Total water reqd per year = 40x365=14600 billion litres = 14.6 billion cubic metres.

Against this, lets check water availability.
Avg rainfall in India=108cm = 0.108m Area of India = 3 million sqkm = 3 million million sq.m = 3000 billion sqm. Total volume of rainfall in India per annum = 3000x0.108 = 324 billion cubic metres.
50% flows into the sea.
Balance 162 billion cubic m Of which we need 14.6 billion cubic m for flushing which is less than 10%.
So theoretically we have enough water. But the distribution of water is uneven. Some states are very dry while other states have surplus.

So we need some kind of river-linking, etc so that water is available uniformly across the country.

Also, nowadays many flush tanks have full flush and half flush system which needs 8 litres and 4 litres respectively. For number1, half flush is enough. So we can reduce water requirement for flushing by 50% to 7.3 billion cubic metres which will be just 4.5% of total water availability in India.
It is doable. But first we need to provide piped drinking water to every home so that people are not worried about septic tank leaking into the borewell or open well water.
