MARINE SANITATION REGULATIONS
All boats with xed 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 dened by the U.S. Coast Guard. Type III systems permit operation of the toilet without direct discharge of untreated waste after every ush. 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 our waters. If
you are interested in learning more about this issue, please visit our website at
www.DometicSanitation.com.
