Permaculture in New Zealand

I've been fixing a standard flush toilet today, continuing my mental observation/study of water in my household and pondering how a desinged household might function

Fig 1. Shows my idealised household water cycle. The household/community collect/consume/use fresh water within the hydrological cycle of their
environment, cycling water through human functions/processes and
returning it to
the bioregion for disposal. Disposal being black water
composting, grey water recycling, reed beds etc... local, decentralised, reticulate and free

Fig. 2 shows the reality of the household water cycle. The outputs of the hydrological cycle have
been sequestered/interceped/stolen by corporations masquerading as municipal entities who
collect or mine fresh water to produce a product called drinking water.
The community consume this product and relyies on the same municipal
entity to deal with the waste by convenient  removal. Household waste is processed along with industrial and agricultural effulent and pumped
into the environment/bioregion at above loading capacity rates - and we pay for it all! Me -$, them +$ my input and therefore support into/of that system needs to be reduced and and if possible remove to an ideal state (Fig1.)

A permaculture design will remove all reliance on the munucipal entity and tend towards the idealised household water cycle

Blue lines = fresh water
brown lines = grey/black water
yellow lines = drinking water
black lines = contaminated (heavy
biological or toxic loading)
