Draining out the bottom as this is not permissable every place you will be camping. 

How crazy is that???  I've tent camped a thousand times over the years. Just about everybody would use Coleman Stoves & Laterns or Open Fire (no elect) When it came time to do dishes mom would get out a rubber pan and dad would heat water in the kettle on the stove. When the dishes were all washed, the dish water got dumped right on the ground. Same thing occurred in every campsite there.

If you will be camping in RV campgrounds the gray water dumping may be more of a problem. I've never come across a horse campground that had a problem with gray water going on the ground.  It's just in some of the strict fancy places that they don't want any pollution of any sort. Really, unless your sink is putting out huge amounts of water, I don't think anyone would notice.  Make it easy on yourself and let it drain out the bottom.  If the place you are camping DOES have a problem, put a pan under your trailer to catch the dribbles, then dispose of the water someplace that is okay.

Ditto to what angel and rocky said.  I'm assuming that you are talking about enough water to wash your face and brush your teeth...not clean the dishes after a large dinner party.

If it's okay for the cowboy shower to drain onto the ground, why not a small sink.

I say run that drain out the bottom and let 'er fly!

RIDE ON!

Kesta, Thank you for catching your water at the show grounds. At a National event last year, I had some friends camping "up stream" that would get up every morning they would run about four individuals through the cowboy shower. Then in the evening they would tidy up their dishes and silverware for the day. So for a week, there was pretty much a constant flow of bath water along with the hamburger grease, butterbean skins, spaghetti noodles and grease, etc. etc. I was the last trailer along the line, next to the curb and most all of this is damming up underneath our trailer!! I say something to them about their "campsite hygiene" and they look at me as though I had slaughtered their horses!!! They didn't seem to care, they didn't have to walk through this filth. This was in the camper parking area at the Tennessee Miller Coliseum, in Murfreesboro. It's a stone gravel lot but still, there's showers and bathrooms less that 150' from where they were parked!!!

WOMEN CAMPERS!!!!

I try to be considerate as much as possible. If I absolutely need to drop my gray water, I will open it so it trickles out all nite long to have less impact on the ground and my neighbors. If it is a pristine area or near a stream, I will bucket it elsewhere if my onboard tank is filled up. Alot of state and national parks have strict rules posted about no dumping of gray or black water allowed except at the dump station. Some will actually test for nitrates. I have always wondered how they could tell if the positive test was from your trailer or the trailer that was parked there before you. These are usually the places that have the no tying to your trailer  or in the camp, signs posted.

I guess there are always going to be the people that push the proper campground etiquette boundaries, like the dog walker that lets their dog poop in your designated space and then walks off leaving it for you to dispose of.
