Greywater Treatment

[sailmania]

Hi all,
Can anyone describe how the standart water treatment system for greywater works in regular sail cruiser?
Is it the wastewater pumped to the same holding tank with head? Or can you pump it directly out?
I am curious about how it is possible to manage if there is any room left for another shower in the holding tank while in anchorage or in a Med - town.
I think that I am missing something very simple here?
Help and advice is appreciated.

Grey water is generally discharged directly to the sea. All of the regulations I am aware of are for black water.

Down the hole and out the side.

Just don't let it go into the bilge. It will stink it up. It should have it's own sump, and a pump to discharge it overboard.

And, a strainer before it gets to the discharge pump if you want the pump to last.
