Plumbing design on boats

Options
This is the sewage out line and fresh water intake on one of the harbor cruise boats in Baltimore's Inner Harbor.
Notice that the cap is off the water connection that is right next to the sewage pipe. One can see stains from spills.

A little careless handling and, well, don't drink the water.

    why the water always tastes like CRAP on that boat!

    Seems like the holding tank for fresh water should have a fill assembly with a physical seperation between the hose and the fill neck. Also the tank vent is below the flood level rim. That is EPIDEMIC plumbing right there.

    Hard To Judge...

    By just looking at the dockside connections. There most likely are air gaps or mechanical protection near or part of the potable water storage tank and the sewage holding tank.

    Water fill systems are most likely pressurized while the sewage side is probaly a vacuum type system with an on board back up pumping system. I was born and raised on the shores of "Gitchee Gumee" (Lake Superior) I would have to go back home and look up a friend who owns the Ferry service to the" Apostle Islands".

    Maritime codes change like everything else but I am sure cross contamination has been addressed.
