One of the keys to making any nutrient stripping system work is a
harvest.
Nobody has mentioned that. Without a harvest, the uptake of nutrients
by
reeds, or whatever, will drop off, and nutrients will build up in the
system. You need to harvest biomass, to remove the nutrients. So
what will
you do with the harvested material? I'm not suggesting this is a
stumbling
block, just something you have to consider in your design and
planning.
Having designed some of these things myself, I think your best bet
might be
to reconsider. Is your objective to have ponds or is your objective
to
dispose of nutrients? If it is the latter, I would opt for a small
orchard
with a subsurface irrigation system. Make it big enough that you can
shift
where you are irrigating. You need some good figures on quality of
grey
water, and, if you use land disposal you need some good soil tests.
You
need to do a lot of work. As for the house in Sydney... I watched
that
programme. It was very interesting and informative. One of the big
things
it got across was just how much work is involved in maintaining a
system in
working order.
