Water needs Water groups In my investigation I found out that there are 3 groups of ‘water quality’. 1) hot water, high standard: a) kitchen; b) floor heat; c) washing machine; d) shower; e) washbasin. 2) cold water, high standard: a) kitchen; b) washbasin; c) roof solar collectors. 3) cold water, medium, low standard: a) toilet + faucet; b) toilet bathroom; c) shower; d) garage; e) garden; f) tap point outside. Water separation Our idea is that there are 3 ways of water input. 1) Waterworks, water quality is low to medium; 2) Rain that is floating to the water tank(s), water quality is medium; 3) Water floating from the water tank to the pool, water quality is high. If we want to reach that the exact quality of water is on the right place in the house but also if there is a shortness of one of the water inputs that we can rely upon other sources, we had to design that all water inputs could reach everywhere. After a while the next creation solved the problem. On the right you see the picture where the inputs come from beneath. With 3 inputs and 3 outputs you can create all possibilities. Pressure The water from the waterworks has his own pressure but if you create your own water source, it´s not there. So for the input from the water tank and the pool we have to organize that.
