Finally, Buildings Are Going Net- Zero Water With #Composting Toilets
The photo shows Envirolet VF Vacuum flush systems, where, I have noted in an earlier post , an electric pump is connected to a Dometic vacuum toilet, mascerates the waste and toilet paper, and sends it to the composter. For the user upstairs, it will be a perfectly normal experience, sitting on a porcelain bowl. However it is not a completely water free system; you can see a white plastic drain pipe leading down from the upper unit. This normally has to be treated in some form of septic system or sent to the sewer system. It is a small demonstration of the real difficulty in going "off-pipe" rather than going net-zero, where a building might still be tied into the distribution system.
