It sounds like you have a "gray water" tank. There was a lot of talk a few years back about banning even gray water discharge in certain areas (Newport/R.I. is one area that comes to mind). It may be that they decided to anticipate this potential headache for owners and came up with a grey water holding tank/sump that could be discharged via a bilge or macerator pump or pumped out at the deck?
