Should I consider a greywater system?

I had this idea in my head that I could create a little stream running from a greywater outlet pipe down to an area where I would love to have a pond. Plant the right weeds along the stream, use gravel, etc. and it would be filtered until clean by the time it reached the pond.

Then I did some research (put a library hold on Art Ludwig's books) and was browsing Ludwig's website. And it seems like none of what I imagined is doable with greywater. So I'm left wondering if I should bother trying to install a greywater system. It can't be stored, and it can't be used to water vegetable gardens. So what can I do with it?

I don't have lawns - I have fields that I let go dry and dormant when the rain stops. And I don't care about them being green anyways.

I don't have an ornamental garden. I don't have fruit trees (though I may get some after our house is built).

I grow a handful of veggies and plan to expand my garden.

It rains plenty here in the winter, so what would I do with it then?

I hate seeing perfectly good water running down the drains, my biggest peeve being the cold water as I wait for the hot water to show up (wonder if small, on-demand heaters near "wet" rooms would be less wasteful?), so I would like to avoid that waste, but this just doesn't seem practical.

What am I missing?

It is possible to have the pond but not the stream.

Actually, I think you can have a stream if you don't mind it being run from a pump and channelled separately from the grey water entering your system.

The grey water needs to be thoroughly filtered and cleaned before it enters your pond/stream system by running it through a reed bed system. Once that water has entered the pond there is nothing to stop you pumping it to a water feature like a fountain or a section of artificial stream. I have seen one installed to good effect here over a length of about 20 meters through a wildlife garden. It has a membrane and then is stone and gravel lined. The owner has commented on the massive increase in bird life and other species since it was installed. It is 12 inches wide at most and the flowing section varies but is mostly about 2 inches deep. It is powered by a standard fountain pump.

Oh that is good news, thanks both of you!

The drawing is exactly what I had in mind...

I'm getting close to being next on the list for Art's book from the library, hopefully it will have some more info on what you have described.

Can either of you point me to any other resources for designing and building such a system as pictured/described?

I have a large length of rubber liner that you can have, if you decide to go with a long skinny system, that mimics a stream. It's about 32 inches wide and 18 ft long.  It was part of a pond liner. I'm in Victoria.
