Can you dump Grey water on the ground?

I see all these van dweller's and sprinter conversions and they use outdoor showers with biodegradable soap and just shower and let the water fall on the ground. I'd imagine if a guy got caught in a state or national park with a grey hose ran over the hill you'd get in trouble. Why is one ok but not that other? Is it illegal? I'm sure it's frowned upon. Just wondering.

When we tent camped the dish water was thrown in the bushes. I wouldn't dump a gray tank from an RV just mostly because of the huge volume plus it contains greases etc from the kitchen. Showering outside is no different than washing in a lake with biodeg soap.

It's illegal virtually everywhere. That said, if you get caught. Remember, dish water can contain food particles, grease, etc., so it's up to you. I definitely wouldn't do it in a National Park Service site, state park, city park, private campground or Walmart.

Volume is the main reason I think it is frowned on. If everyone did it all the time 10 plus gallons at a time at the same spot... it could start to smell and might even cause issues with the surrounding environment and animals. That being said I dump my gray tanks at my house at times with no worries but it is my land.

I have been tent camping with Boy Scouts and family for a long time now and we always have grease, food particles, and soap in our dish washing station we setup at camp. Guess where that goes? On the ground in the woods or field away from tents and other people camping.....

In Arizona, anyplace, dish water is considered black water since it contains food particles which draw animals, bugs etc. In a campground I have never seen a situation where it is not only legal but encouraged to allow any water from campers to be dumped on the open ground.. Common sense and good manners would suggest it can't be good if someone were to dump anything on the ground consistently. Just because you can, doesn't mean you should. Even in the desert, shower water with biodegradable soap will evaporate but not enough rain is present to wash away the soap residue.

We use some of ours to douse our fire. The rest stays in the tank to flush the black hose. We only boondock. Iím sure campgrounds would have something to say about it

It's illegal and also not a good practice in congested areas. 20-25 years ago it was acceptable in many public places.

The first or second night I pulled in to a truck stop when I was a rookie CDL driver, I was shocked to see the guy next to me open up his door and dump his "bottle" on the ground outside his truck. Let me tell you that was by far not the worst thing I've seen deposited on the ground at one of those places over the years.

Anyway, I'm not suggesting that anyone should willingly dispose of grey water in a manner that is against local regulations or in an unsanitary manner. However, I find it comical that municipalities and agencies would regulate grey water from an RV but totally ignore what goes on in places like truck stops and rest areas.

Years ago rv’s didn’t even have grey tanks.

One thing is for sure, grey water becomes "septic" in a short time. I have no problems with dumping the grey tank on the ground at my house after 2 nights of camping. I prefer to dump it at dump stations. No I wouldn't do that if it was in the tank for a week.
