It does, but it isn't.
Similarly multiple out-going pipes to split off various levels of grey waste (some direct to garden, others, to soakways, or to septic processing systems).
Capex for these kinds of systems is ultimately dwarfed by savings on opex - just like we find with mandatory double-glazing & other insulation regulations.
- nerdponx 9y agoMakes sense. But out of curiosity, where are you getting that info? Personal experience? Research in some field?
- Jedd 9y agoMostly personal experience including some stories from permaculture types who've been approaching these problems for a while. I'm designing a habitat that will have an additional complication of both low-pressure gravity fed and electric-pump (city pressure) circuits. Regulations lag behind optimum configuration, though parts of EU, especially in the north, legislated triple-glazing (f.e.) quite a few years ago (can't find a cost analysis of break-even points, unfortunately). I'm sure there's plenty of assumptions wrapped up in these regulations around estimated abode longevity, energy pricing over that period, etc. But as to multiple water sources into abodes, I haven't seen much formal work on it. I think the idea gets touted in London periodically - it'd be a nice solution to the dual problems of high water table and (surprisingly) occasional potable water shortages. But retrofitting this to an existing, massive, badly planned metropolis would be a nightmare.
