Head System
Environmental Considerations
The Environmental Protection Agency (EPA)
standards state that in freshwater lakes, reservoirs,
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 traffic subject to this
regulation, marine sanitation certified by the United
States Coast Guard (U.S.C.G.) installed on vessels
shall be designed and operated to prevent the
overboard discharge of sewage, treated or untreated
or any other 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 the waters where
a Coast Guard certified marine sanitation device
permitting discharge is allowed include: Coastal
waters, Estuaries, The Great Lakes and Intercoastal
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)
This vessel is equipped with a waste containment/
disposal system. The system includes a VacuFlush
toilet, a 12 gal. (45L) holding tank with vacuum
pump, macerator, lockable discharge seacock,
dockside pump-out connection, and a thru-hull vent.
NOTICE
This boat is equipped with an overboard
discharge seacock. Severe state and federal
penalties are levied for discharging raw sewage
and solid waste in waters where it is not
permitted.
The macerator can be disabled by attaching a
wire tie or padlock to the seacock or removing
the seacock handle while in a closed position,
which would avoid potential fines.
It is illegal for any vessel to dump plastic trash
anywhere in the ocean or navigable waters of
the United States.

MACERATOR
Macerator/Discharge Pump
The macerator/discharge pump (see Figure 3.15.1)
draws solid and liquid waste from the holding tank
and processes it prior to discharging it overboard
®
through the macerator seacock located in the aft bilge.
The macerator is designed to handle waste, toilet/
facial tissue and does not pump solid waste. The key
used to actuate the overboard discharge unit can be
found in the owner's packet.
NOTICE
The low-water consumption waste system
requires the use of special paper to prevent
clogs. The manufacturer has provided
information regarding the type of paper that
must be used. Never use residential tissue
paper in your marine waste system.
!
The discharge seacock should always be in
the closed position when the toilet is not in
use. Failure to do so could result in flooding or
property damage.
