I like the Earthship grey water set up, but would like to hear other solutions to flushing toilets with use shower/sink water without the need for a botanical cell running through the property.
We are having our home built with two 1,000 gallon septic tanks; one for the toilet and the other for gray water.
The gray water tank won't have leach lines, simply a filtered overflow for a living pond.
The gray water in the tank will be pumped out to primarily water the orchard and wild flower meadow the wife calls her secret garden. She has some wild plans for it, including big stumps pulled from the ground, cleaned of dirt and rocks, and displayed at certain points in the "garden". Guess who'll be doing all THAT work!
Anyway, that's the plan. If your house has a crawlspace you can retrofit a gray water catchment system to your plumbing. I'd seek the advice of a licensed plumber before cutting anything loose. There are codes one must follow. In some places you might have to get a permit and pass milestone inspections.

Creator, make me fast and accurate. Let my aim be true and my hand steady. Let my weapons put fear in the hearts of those that wish harm to me and mine. Let not my last thought be, "If I only had my gun". If today I draw my last breath on this earth in defense of my country, my family or my honor, let me die in a pile of empty brass
