I've been to a couple of camp grounds that have a BRAY Water pit in each road feeding the trailers...
This is the one for CLOUDLAND CANYON at Trenton, GA

We always ask when camping in the Natl Forest etc... Most of the time they say go ahead and dump around the tree trunks...
I would definite not just let it drain on the ground at the camp site. The next guys that gets your site is going to have a stink I'm pretty sure...
Most of the time we carry our gray water to the localizied bath house building abd pour donw the pot. Then we bring back fresh water when available (with another water can) to add to our frest water tank. Sort of a daily routine
This is what we do at any rate and most of our RV Camping is OFF-ROAD back in the woods somewhere...
