MArINE SANITATION rEGUlATIONS
All boats with fixed toilets in U .S . waters and in the waters of some other countries
are required to have an operable, permanently installed marine sanitation device
(MSD) . Series 970 MSD models, when permanently installed in a boat, are holding
tank or Type III systems as defined by the U .S . Coast Guard . Type III systems permit
operation of the toilet without direct discharge of untreated waste after every flush . Type
III systems can be discharged at marina dockside pump-out stations or, if in coastal
waters, a minimum of three miles offshore . Overboard discharge capability must remain
secured while within the three-mile limit . If an overboard discharge pump is activated by
a keyed switch in the toilet compartment, the key must be removed at all times except
when discharge pump is operating and in the process of vessel operation .
Sewage from any source should not be discharged directly into boating waters .
