central: wow, I’ll pee on the compost pile from now on.

Dust: I’ve been told that grease stops up septic systems.

witch: you would need to treat grey water as you would any outside water source that is being treated, meaning filtered and or purified. If you buy the earthship books, they show you how to make an inside planter filter. You can even pump filtered water from the bottom of it. I will be posting an article on my blog soon on water treatment, purification and filtration.

If you pass grey water through an RO filter system you can receive half back as pure clean water. Note that you still want to purify water after this process with iodine, chlorine or by passing it through a ceramic filer with coloidal silver. The reason is that some bacterias can build up on the product water side of the RO Filter. Note that model on the diyreverseosmosis site its 50% efficient at 70psi, meaning for each gallon you run through it you get 1/2 gallon clean water. Also note that you still end up with grey water after this process, its the 1/2 gallon that didn’t filter. It is concentrated grey water. This could still be sent to a planter/sand filter or distilled in a solar stil. A 8’x4′ solar still can get you 1.5 gallons of distilled water per day in summer.
