Is there no problem dumping grey water on the ground in campgrounds? My grey water doesn't have food particles or grease. It's only hand soap, or dishwashing soap.
I thought I was told gray water discharge is a violation of the Federal Clean Water act and is subject to some rather severe penalties? (although I have never seen anyone police this in a camping area)
We have camped in campgrounds that provided french drain/nitrification pits for gray water which I thought was novel and helpful.
