The Environmental Protection Agency (EPA)
standards state that in freshwater lakes, freshwater
reservoirs or other freshwater impoundments whose
inlets or outlets are such as to prevent the ingress
or egress by vessel traffic subject to this regulation,
or in rivers not capable of navigation by interstate
vessel traffic subject to this regulation, marine
sanitation devices certified by the U.S. Coast Guard
installed on all vessels shall be designed and
operated to prevent the overboard discharge of
sewage, treated or
untreated, or of any waste
derived from sewage. The
EPA standards further state
that this shall not be
construed to prohibit the
carriage of Coast Guard-
certified flow through
treatment devices which
have been secured so as to
prevent such discharges.
They also state that waters
where a Coast Guard certified marine sanitation
device permitting discharge is allowed include
coastal waters and estuaries, the Great Lakes and
interconnecting waterways, freshwater lakes and
impoundments accessible through locks, and other
flowing waters that are navigable interstate by
vessels subject to this regulation (40 CFR 140.3).

The Vacu-Flush
®
head utilizes the HEAD breakers
on the DC distribution panel in the salon. Individual
breakers on the DC distribution panel control the
GUEST HEAD and MASTER HEAD. The foot pedal
at the base of the toilet opens a mechanical seal
and vacuum forces waste through the opening in
the bowl to the vacuum generator, through the
vacuum pump and then to the holding tank.
