Me wanting to build my own home is not just because I want a porch that surrounds the premises, and it is not just because I want well spaced rooms with custom designed walls. I want to build my own home because I don't like defecating on water that is clean enough to drink. Here in the UK, clean drinkable water is produced on a large scale so some of that water is supplied to the toilet flushing tank, I don't like that; it just doesn't feel right to me. I feel like it is wasteful to defecate into water that has been cleaned extensively.
I want to defecate into the grey water that comes out of the back of a washing machine or the soapy water that comes out of a shower cubicle. It is more logical to me to defecate into water that is already dirty. To produce the water would be straight forward.
Firstly, rain water would be collected into water tanks in the attic. Then the collected rain water would be used in the clothes washing machine and shower. Then...
Secondly, the used water from the showers and washing machine would flow into another tank that fills the toilet flushing tank. When you flush the toilet, water would take away the waste.
The microbes that reside in the grey water tank would adapt to the detergent and soap and find a way to break them down so the gray water tank would give off heat.
All the sink basins would still use tap water that is cleaned in the plant because water from the roof could contain harmful microbes but you don't eat your clothes or lick your skin after a shower and rain water has no dissolved lime stone in it so it is good for the washing machine.
