Waste and Sanitation Systems

IMPORTANT: You must ensure it is legal to empty your
holding tank in the waters you occupy. Some areas
have restrictions on pumping out black water waste!
10.5.3 Holding Tank Operations
The holding tank must be emptied when it approaches
a full state. There are two methods for removing waste
from the holding tank:
Overboard discharge when in waters where it is
legally permitted
Dock side pump-out at a waste facility.
Check with the Coast Guard and local authorities before
discharging waste overboard.
10.5.3.1 Overboard Discharge Operation
To discharge the gravity feed holding tank overboard,
one simply opens the overboard discharge Y-valve. The
valve (Fig. 10.13) is located in the vanity shower and
accessed through the lower outboard access panel.
Figure 10.13
To close the Y-valve, rotate the handle counterclockwise.
To open the valve to seawater, rotate the valve to the
straight up position.
IMPORTANT: U.S. Coast Guard regulations require that boats
have a sanitation system on board to control pollution. Waste
is to be stored in a holding tank or other device so it can be
properly disposed of at a shore facility. Discharging this waste

overboard in U.S. lakes, rivers, bays, and sounds and within 3
miles of shore in international waters is prohibited. Check with
the Coast Guard regarding regulations in your area.
WARNING
! !
Failure to close the overboard discharge valve when
not in use could cause the holding tank to fill and
possibly flood the boat.
WARNING
! !
Waste in the holding tank can form methane gas.
Use suitable precautions when any maintenance is
conducted to the sanitary system.
10.5.3.2 Dock side Waste Removal
To remove waste from the holding tank at a dock side
waste facility, insert the hose from the pump-out facility
into the waste access (Fig. 10.14) located on the port aft
side-deck and follow any instructions. Instructions may
vary from one facility to another.

10.5.3.3 Maintenance on Holding Tank
Maintenance on the holding tank simply entails manag-
ing odor and ensuring no methane gas leaks exist. Any
deodorizer may be used as long as it contains no alco-
hols or strong chemicals. Do not use strong drain open-
ing chemicals or bleaching agents as they may cause
serious damage to the system’s seals and hoses.
