while the filtering and disinfecting requirements differ for reusing true gray water from state to state just about every state including GA has strict rules for reuse of gray water and protecting against the dumping of the same while encouraging safe reuse at the same time…
I would love to know which professional or college teams use un filtered or un treated gray water for playing field irrigation, especially a top irrigated system…
Since bacteria can grow very rapidly in held gray water many consider even gray water as septic if held for 24 hours... that would require sanitizing the tank and piping before it would be gray water again… most RV gray lines use at least some of the same lines for black water and allowing the gray to enter and flush the black tank allows cross contamination, along with the residual water held for weeks between trips… I would also guessing many RVs collect kitchen waste water in the same tank as the shower meaning that RV has no true gray water containment system to begin with…
“So what does a tent camper do with his dish water?”
The most common refrain to justify the lack of commonsense when disposing of waste while not in a tent…
There are many articles describing the use of and disposal of small quantities of unheld (pan) dish water… I really don’t recall ever seeing it recommended to dump it on the top of the campsite ground…

Primitive Camping
When primitive camping, or backcountry camping, follow backcountry ethics regarding water disposal. This holds true even if you're camping on private land that isn't governed by specific water disposal laws. As the U.S. Forest Service says, straining and packing out food particles from dishwater ensures the waste won't enter the ecosystem. Likewise, campers must dispose of dishwater at least 200 feet from bodies of water, including both still and moving water. When bathing, campers must use biodegradable soap and stay at least 200 feet from water bodies (see References 4). They must follow the same rule when brushing their teeth.
