I know we have a lot of boon dockers here so I thought I would share this. Here is a link to instructions on how to make a grey water filter using a 5 gallon bucket. Once I get the plumbing working on my boler
, I will probably try this out. I don't know if I'd drink the water coming out even with the carbin filtering layers but you could definitely use it to flush the toilets or even to wash dishes (after boiling). it looks like the water would be clean enough to dump on the ground without causing the typical issues.
