[permaculture-oceania] RE: Grey water reticulation

[Robyn Francis]

Re surge capacity, Dan Deighton (My Kembla) has a series of pickle barrels
connected to each other with pipes at the bottom of the drums, water keeps
moving through from drum to drum. For surges from a wash machine a larger
diameter pipe connecting drums would help.

Hey Cam, can you let us know when you track down a supplier for the Netafim
brown poly you mentioned.

Ciao
