Some OH state parks have stone sinks for you to pour gray water in, they run into a pipe that daylights out into the woods a few feet away. WV's drain into a gravel sump which overloads quickly then runs off to wherever. Prior to the 1980s at state parks everyone had a hose run off into the woods for gray water before the tree huggers came along. The campgrounds, trees, and wildlife is/are all still there.....Defund the gray water police.
