My husband and I have been kicking around the idea of rerouting and extending the greywater drain from the house (sinks, bathtub, washing machine) out to our little Piggie's run to create a wallow. Logistically, its not too far from the house and we like the idea of her being able to play in the mud anytime we use water in the house. We live in Florida, and while she has plenty of shade and a kiddie pool, we'd like to give her a real mud wallow while taking advantage of an essentially wasted resource. My only concern would be skin sensitivity to some of the soaps we use, but we have a child and thus try to use sensitive formula or green products whenever possible. Any thoughts?
