Waste and Sanitation Systems
10.4
A diaphragm type pump with strainer is used for the
shower sump. Refer to the Operation and Maintenance
subject of this section for details on the servicing or main-
tenance of the shower sump. Fig. 10.3 shows you the
sump pump.

Later in this section, we will discuss in greater detail,
the process in performing routine maintenance on your
shower sump.
10.2.4 Macerator Pump
The macerator pump disposes of black water discharge
or raw sewage. This will be any material from the hold-
ing tanks.
Your toilet pumps the material to your holding tanks, then
when you are in legal waters to dispose of the materials,
you can remove the materials from your holding tanks
with the macerator pump. Refer to the Operations and
Maintenance subject in this section to learn how to oper-
ate the macerator safely.
The macerator pump acts as a garbage disposal in your
home. The pump contains “chopping wheels” that chop
and grind the solid waste into pieces small enough to
pass through the discharge hoses and the overboard
discharge valve.
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.
Refer to the mechanical arrangement illustration in the
Boating Safety section or the Sanitation arrangement
at the end of this section for location information for the
macerator pump. Fig. 10.4 is the image of the pump.
10.3 Other Waste Related Equipment
10.3.1 Engine / Generator Exhaust
The subject here will be discussed in the Engine &
Transmission Section. The motivation for placing this
subject in the Sanitation System Section is due to the
fact that exhaust is discharged from your boat. We will
have an entire subject concerning engine and generator
exhaust in the Engines and Transmissions Section. Here
we will simply mention that the exhaust is a gas, Carbon
Monoxide (see Boating Safety Section) and is very
dangerous. Be sure to follow all guidelines concerning
Carbon Monoxide.
10.3.2 Holding tanks
The holding tanks on your boat is installed to hold black
water waste until you can safely dispose or pump it
overboard. Refer to the Arrangement Illustrations in the
Boating Safety section or at the end of this section for
location information about the holding tanks. Refer to
the Operations and Maintenance subject of this section to
learn how to perform maintenance on your holding tanks,
or to learn how to pump it out.
Remember: You must make sure it is legal to empty your hold-
ing tank in the waters you occupy. Some areas have restric-
