• Waste and Sanitation Systems
10.2
This section outlines the use, care, and maintenance of
your boat’s sanitary systems, as well as, bilge pumps and
waste systems.
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
three miles of shore in international waters is prohibited. Check
with the Coast Guard regarding regulations in your area.
Sanitation Systems
Your boat has a sanitation and bilge system that is the
cutting edge of sanitation. The components are designed
to fit the most demanding environment. Some of the fol-
lowing components are listed in the Sanitation and Bilge
Section.
Head Systems
Drains
Pumps
Holding Tank
Macerators
Shower Sump
In this section, we will break the systems down into a
format to help you better understand how your systems
work and what it takes to maintain them. These systems
are further divided into four types of discharge, Gray
water, Black water, Raw water, and Gaseous discharges.
The gray water system is comprised of waste that is not
considered raw sewage, which is categorized as Black
water. Raw water is the cooling water that is taken in
through pickups, etc. and discharged back. Gaseous
discharges are your exhaust, or fuel vents. Parts of
the sanitation systems are Drains / Discharges, Pumps,
Holding Tanks / Sumps, the lines or hoses that feed or
drain these systems, and the components that make up
the collective point for waste, and the access point for
sanitation.
10.1 Drains / Discharges
Most drains are in the form of through hulls or overboard
discharges. These fittings connect to a component, or
line, that is routed from a collection point or point of waste
origin. Any waste outlet that is gravity fed would be called
a drain. Likewise, anything that was fed by a pump would
be called a discharge.

Macerator discharge
Combined vanity
/galley drain
However, waste is not limited to liquids, so, an example
might be the exhaust system on your engine or genera-
tor. This system disposes of the Carbon Monoxide gas
through the exhaust system.
Overboard discharge (Opt)
Fwd macerator discharge
Vanity sink drain
In this section, we will cover all the types of drains and
discharges aboard your boat, give you the details of how
they work, and the information so you can maintain these
components.
10.1.1 Through Hulls
There has to be an outlet or a way to discharge the liq-
uid waste. These are called through hulls, and they are
openings in the hull or sides of your boat with bronze
fittings. These are fitted to drain hoses and sized to be
compatible with the system that they drain. At the end
of this section, you will find illustrations showing you the
locations of your through hulls and their specific func-
tion. The hoses that feed the through hulls on your boat
are looped over the fitting in order to prevent any water
or waste from leaking or draining back into your boat.
Fig. 10.1 and fig. 10.2 give you a look at some through
hulls. Vents, also shown in Fig. 10.2, are another type of
through hull and, yet another type of waste disposal.
