Water management

Q: An individual drinks/consumes only about 5-10 litres of water in a day but the amount that is used up for other purposes is about 150-200 litres, which is what needs attention.

There will not be any water shortage if we just separate out our used water as GREY WATER & BLACK WATER. Grey water can be completely recycled and recharged in to the ground, with out using electricity.

For example an apartment of say about 500-600 family units would be letting out about 4,00,000 litres of water per day. Out of this about 3,00,000 litres per day can be recharged back to the ground. Do you think with this kind of recharge there can still be any water shortage?

Let me know if you need more information.
