Right now we're dumping it into a big trashcan and it fills that trashcan UP twice, once with wash water, once with rinse water. On the small cycle! Between, Steve hauls it out with a bucket into the yard. Just to ease the load on the septic for right now.
But really, that is a massive amount of water for just slightly soiled clothes that can be used for other purposes...
Heh... my Dad loves to obsess about how much water goes through the drain field.. and they do have some fancy low-impact systems that re-use grey water from sink drains and washing machines to flush the toilet.
