Net Zero Water Building

The American Government has developed the idea of net zero building  (see scheme below) and now that I see it in its official configuration, I say it is unsustainable, it is fantastic money burning machine, pure unadulterated, preservers-free nonsense. It requires about ten times the length of piping of a conventional house, many pumps, and control systems, it requires space to connect all these pipes (and space within the building is very scarce), it requires a spacious underground basements (with lighting and air conditioning), it requires two underground water tanks (and a large one for fire fighting, did they forget?) and two water and sewage purification facilities (consuming lots of energy and chemicals) and so. The maintenance of two WWTPs is a headache, just think of the amount of plumbing work required to maintain a simple conventional building. What if the electricity supply is unreliable? The sewage will rot and contaminate the building? The health risks of a conventional building are serious, imagine how dangerous will be here, having abandoned the proven, centuries-old concept of disposing of the sewage immediately and as far as possible from the building, here it is storing and manipulating it. The chemical disinfectants like chlorine and additives like flocculants required are, in themselves, a pollution source. It is a nightmare, I would not live in such a bad-smelling, dirty, polluted, unhealthy house.

On the other hand, the water and sewage supplied by the municipalities are perfectly good and very inexpensive. Why should we want to disconnect from public services? The concept is sick and crazy.
