I agree with your sediment but it is not so simple.
The problem is grey water becomes "black water" after a few days. My understanding the time for change is variable depending on temperature and solids contaminantaion If grey water is dropped onto ground directly with a simple fine filter to remove solids it is pretty safe.
Too complicated to develop a solution on my pay scale.

'Sediment' - very fitting.
Yes what is initially fairly innocuous becomes stinky, unpleasant & potentially dangerous if stored for more than a fairly short time.
My view is that grey water tanks would best be sized to carry only 24 hours worth of waste. All sorts of reasons why this may not be practical, but a general encouragement to get folk to dispose of their grey water daily should IMHO be a more important focus than it is. I tend to think that folk who might argue that the whole point of having larger tanks to last for longer before emptying are part of the problem (& often quite righteous about it).
Often I think that campers without grey water tanks, who use minimal water & create minimal waste - spread thoughtfully onto the ground, are far more considerate to our environment & to others than those who are large water users with large holding tanks - especially those who empty those large tanks on roadsides or worse - dribble as they drive.
Many caravan parks allow grey water to be discharged on the ground, those who dont usually have grates for your grey water to enter the storm water system, some have it eventually enter the local sewage system.
If you are at a caravan park that only has a local septic system, they really dont want grey water to enter that system because some vanners may use chemical that would kill the septic, thus requiring them to be pumped out.
If you are at a self contained facility then take it with you, I asked in a thread about bush camping how they contend with emptying cassettes, the response from some was to dig a hole and empty it the cover it up.
The word soldiers was mentioned I know they are not the one's in uniform, in my days out in the bush we would use an entrenching tool to dig a hole to take a dump in, and any tree or vehicles wheels or track were good enough to take a leak on.
