[permaculture-oceania] Grey water reticulation

[Peter McDonald]

Dick,

I have a sewerage sytem designed by Biolyitix at Maleny in the hinterland of 
the Sunshine Coast..it is a company run by a a guy called Dean Cameron. You 
will find their contact details on their website. They may be able to supply 
the non-block pipe in a variety of sizes in much smaller quantities than 200 
metres. I use it to disperse my sewerage water underground (council 
regulations) and it works a treat.

My Alpacas graze on the dispersal are(400 sq metres) with no ill effects.

Good luck

Peter McDonald
