Some rides are held on private land. Some land
owners may request you do not dump your grey water out in their field. I've also
camped next to someone at a ride who had their grey water running off on to the
ground, right over into my campsite! Be considerate of not only laws, but
others. Don't create a mud hole in camp etc.
It may or may not be the law to allow your grey
water to spill on the ground, but is it good manners at a ride???
