Waste and Sanitation Systems<br />
10.1.2 Overboard Discharge<br />
Some discharges have valves associated with them. The<br />
Black water, or Raw sewage system from the head is one<br />
such system. Located near the macerator pump (Fig.<br />
10.5) (discussed later in this section), is the Overboard<br />
Discharge Valve. This is a ball type valve in which the<br />
chopped solid waste from the holding tanks is disposed<br />
of after passing through the macerator.<br />
Basically, all pumps are somewhat associated with the<br />
Waste / Sanitation system, but in this section we will<br />
focus on the pumps that are directly associated with the<br />
process of pumping waste overboard. The supply function<br />
of these pumps are discussed in other sections.<br />
Note: The Overboard Discharge Valve should remain closed at<br />
all times except when in use.<br />
Should the water level rise above the high water mark,<br />
and the emergency bilge pump comes online, you will<br />
hear a high water alarm from the helm along with a solid<br />
red light. It would also be important to mention here that<br />
when you hear the high water alarm (Fig. 10.3), it means<br />
that high water exists in the bilges and it is time to take<br />
action. Refer to the “Chapman’s Piloting, Seamanship<br />
and Boat Handling.” We have supplied you with a copy<br />
of this book aboard your new boat, but if you do not have<br />
one, it is a wise idea to purchase this boating manual. It<br />
is full of useful safety and navigational information.<br />

10.2 Pumps<br />
Probably the most important pump system on your boat<br />
is the bilge pump system. Your boat is supplied with one<br />
bilge pump and one high velocity emergency bilge pump.<br />
All are part of the Gray water system. This emergency<br />
bilge pump has the pumping capacity of 33 gallons a<br />
minute from your bilges. Your other bilge pumps vary<br />
according to boat model and size, please refer to the<br />
documentation for your bilge pumps for the pumping<br />
capacities.<br />
We are concerned about your safety. You should review<br />
all information contained in this manual, as well as, the<br />
manufacturer’s manuals concerning all systems on your<br />
boat, but the bilge pump system will be one that is crucial<br />
to learn. These pumps have the function of clearing water<br />
from the bilges of your boat. You must ensure that they<br />
are kept clean and functional in order for these pumps to<br />
complete that task.<br />
10.2.1 Emergency Bilge Pump (Optional)<br />
The emergency, or High Water Bilge pump, is generally<br />
located in the center bilge compartment of your boat. It<br />
is mounted about 12” off the bottom of the bilge. This is<br />
why it is referred to as a High Water Pump. We discussed<br />
in the DC Electric section about the float switch and<br />
the operation of the pump, so, you already understand<br />
that the water level has to be above a high water level<br />
to operate this pump. Fig. 10.2 gives you a look at the<br />
emergency bilge pump aboard your boat.<br />
Check your Mechanical Arrangement illustration in the<br />
Boating Safety Section for the location, and the Waste<br />
/ Sanitation illustration at the end of this section, for the<br />
discharge hose routing for this or any pump.<br />
10.2.2 The Main Bilge Pump<br />
This pump is located in the lowest parts of the bilge.<br />
The function of this pump is to clear the water before it<br />
reaches the high water level.<br />
Careful maintenance should be made to these systems<br />
to ensure they are always operational. Check the DC<br />
Electric Section, or the Operation and Maintenance<br />
subject of this section, to find the details about operation<br />
of these pumps and the details of how to manually run<br />
them.<br />
10.2.3 Shower Sump<br />
Fig.10.2<br />
Due to the level of the shower drain, we have installed<br />
a pump system to rid the boat of water from your shower.<br />
The small filter also acts as a collection point for hair and<br />
other waste materials that might get washed down the<br />
