Our new/old
boat has a largish (looks to be about 15 gal) graywater
holding tank. The
shower,
head sink, and reefer drain go to it. I just finished replumbing and rewiring the pumpout
pump (Whale Gusher 220). It is all set up nice and has been epoxied in to the upper part of the
bilge just aft of the
mast. The
galley sink goes direct
overboard to a separate
thru hull.
I know that many
boats do not have a central graywater tank and rely on smaller sumps with small pumps for the shower/headsink.
Are there any
regulations or standards as to having a graywater tank like this for the US or other countries? There is not a
deck pumpout fitting so at some point the graywater has to be pumped over the side in any case. But I could choose the location to
pump it out, preferably out and about and not in a marina. But right now, it has to go over in a marina at some point if I
shower or clean up there much.
Any thoughts?
P.S. I am lusting after the location for an increase in
diesel fuel tankage. I would have to remove the existing tank as it would not be suitable. It would be a big
project so it may never happen.
