I know and, here I sit, in our house with no use of grey water and no affordable means to do it, yet.

When we lived on the ranch we hauled our water in a 250 gallon tank behind our Subaru wagon once a week. That was it...we each took boths or showers every day, Rog, the kids and I and we watered the horse, dogs, birds and cats...even had water for ducks, but I never did dishes or laundry. We used mostly paper and had the laundry done in town as I was working full-time, too. It made more sense all the way round even though I'd insisted, early in our living together, that I HAD to have a new washer/dryer, refrigerator and stove and Rog bought them for me.:-)
