R/O waste water

[hummer]

If you have house plants or garden you can probably water them with it. I know one guy who threw it into his washing machine to do laundry.

Hard thing is where to plumb it so it's readily avail? I thought of the 45g drums outside, for garden water etc, But, what do you do in the winter time? The line/water would freeze. My RO system is pretty much automated to keep the top off tank full, usually make 20-30g of RO at a time.
