Raritan offers over 200 sizes and shapes of only the best quality, extra thick-walled, 3/8” (.9cm)
minimum thickness, seamless polyethylene holding and water tanks.
Polyethylene is the only choice for sewage holding tanks because urine is highly corrosive.
Polyethylene tanks won’t corrode, leak, shrink, bulge or crack under the weight of sewage and
also won’t permeate with sewage odor.
Installation diagrams have not been included because “one size fits all” installations don’t fit all
boats. Raritan will help you select the best tank location for your boat, the right size tank, and the
best way to install it. Then we will expedite your tank order. All fittings are installed at the factory
when your tank is made, in the locations, number and sizes you need—eliminating the need for
“fitting relocation kits”.

K.O. KILLS ODORS!
"If You Use a Holding Tank - You Need K.O."
K.O. IS NOT A CHEMICAL PRODUCT. K.O. utilizes live odor-killing bacteria which digests
liquids, solid waste and paper, totally emulsifying them so there’s no need to add “tissue digesters” or
other “boosters” to your system. The bacteria in K.O. neutralize the odor-causing elements in waste,
effectively converting the contents of your holding tank to an odor-free product.
K.O. IS MORE EFFECTIVE THAN ANY CHEMICAL OR ENZYME PRODUCT.
Chemicals only mask odor temporarily. Although they kill odor-causing bacteria, chemicals also kill
other bacteria that suppress odor. Chemicals can actually cause the odor problems you’re trying to
solve! Enzymes stimulate the breakdown of waste already in the tank, but are not effective against
odor, and are diluted by new waste as it is added. Four ounces per 25 gallons of capacity is all you
need, and there’s seldom any need to add K.O. between pump-outs; or need to pump out until the
tank is full, making K.O. less expensive to use than lower-priced products. Unlike chemicals, the
discharge from tanks treated with K.O. is welcome in on-shore sewer and septic tank systems.

ODOR CONTROL IN HOLDING TANKS
It really IS possible to have a completely odor-free system!
You’ve probably read or heard, over and over again, that the key to odor control is the “right”
hose, that the “wrong” hose permeates with sewage and causes the system to stink. That’s
folklore…a little truth coupled with a lot of misunderstanding. The real key to odor control is in
knowing how to incorporate proven sewage management principles—the same ones used in
composting and sewage treatment—into the installation of the entire system. What very few
people in the marine industry have learned, and why there is so much folklore about odor, is the
very nature of sewage itself and how it breaks down, what creates odor and what prevents odor
from forming. Once we understood these principles and learned how to apply them to onboard
systems, we were able to install systems that are completely odor-free and correct the ones that
weren’t. Once you understand it—and it’s so simple!—you can do the same thing.
There are two ways to deal with holding tank odor: try to reduce it, mask it and contain it after
it’s formed, by using chemicals and filters—which has never proven very successful…or prevent
odor from forming in the first place.
Sewage contains both aerobic (needs oxygen) and anaerobic bacteria (functions in an airless
environment); neither can function in the other’s environment. Why is that important? Because
only the anaerobic bacteria in sewage produce foul-smelling gasses! Aerobic bacteria break
sewage down, as does anaerobic bacteria—but aerobic bacteria do not generate odor. So as long
as there is a sufficient supply of air to the tank and an aerobic bacteria treatment is added to aid
that which naturally occurs in sewage, the aerobic bacteria thrive and overpower the anaerobic
bacteria and the system remains odor free.
A bio-active (Iive aerobic bacteria) holding tank treatment, such as our own “K.O.”, works with
the aerobic bacteria in sewage, eliminating odor, completely emulsifying solids and paper and
preventing sludge from forming. Enzymes do little if anything—a brief respite from odor
immediately after adding them, then odor begins to build again. Chemical products mask odor
with another odor and they kill not only odor-causing anaerobic bacteria, but beneficial aerobic
bacteria as well—not good, because the aerobic bacteria are needed in the system to break down
and emulsify solids and paper. Otherwise, they only break UP and dissolve them into little tiny
particles that settle to the bottom of the tank, along with chemical residue, to become sludge that
turns to concrete. Chemicals, unlike bio-active products, are also unwelcome in landside sewage
treatment facilities and are especially unappreciated by those living and working near them!
The bacteria in sewage produce a variety of sulfur monoxides and dioxides (which are the
malodorous gasses), methane—which has no odor but is flammable—and carbon dioxide, which
also has no odor but creates the environment in which the aerobic bacteria cannot function but
allows the aerobic bacteria to thrive. Carbon dioxide does not rise or fall, it is ambient—like the
atmosphere, but heavier than air. Without a sufficient flow of fresh air through the tank to allow
it to dissipate, it simply lies like a blanket on top of any pool of sewage (whether inside hose or a
holding tank) and builds, suffocating the aerobic bacteria and creating the perfect environment
for the anaerobic bacteria to take over. The system literally “turns septic” and the result: a
stinking boat…or at least foul gasses out the vent line every time the head is flushed.
To prevent this, let’s start with the head: the discharge hose, no matter whether it goes
overboard, to a Type I or II MSD, or to a holding tank, should be installed, if at all possible, with
no sags or low places where sewage can stand. When a marine head is not flushed sufficiently to
clear the hose of sewage and rinse the hose behind the sewage, that sewage sits in low spots in
the hose or bits of it cling to the walls of the hose—getting no air, allowing the anaerobic bacteria
to thrive and produce their stinking gasses. If sewage stands in a low spot which gets no air in
hose which is susceptible to a high rate of water absorption, it will permeate the hose. This is
what has given rise to the myth that the “wrong” hose causes odor. Therefore, it’s important to
flush your head thoroughly enough to clear the entire hose of sewage and rinse behind it. And
when you leave your boat to go home, flush the head thoroughly one last time, this time with
fresh water. Until holding tanks came along, the hose was the source of most odor, but
incomplete flushing was the real cause.

In the holding tank, the key to odor control is the vent line; it must allow a free exchange of fresh
air for the carbon dioxide generated by the sewage. Therefore, those bladder tanks which have
no vent are all but guaranteed to stink; there’s no source of air into them at all. Boat builders,
boat owners and boat yard personnel who install holding tanks have always viewed the vent line
only as a source of enough air to allow the tank to be pumped out without collapsing and as an
exhaust for methane. (Many even believe methane—which in fact is odorless—to be the source
of odor.) Some take the attitude that tanks must inevitably stink, so the thing to do is run that
vent line as far from people areas—cockpits, sun decks, etc.—as possible, or make the line as
small as possible, or install a filter in it. All of the above actually create the very problem you
want to solve.
Think of the holding tank as a stuffy room which needs to be aired. You know that even if there
isn’t a hint of a breeze outside, just opening a window will allow the fresh air outside to
exchange with stuffy air in the room. Open another window for cross-ventilation and the air
exchanges even faster. However, just opening a skylight accomplishes nothing unless there’s
also a mechanical means (an “attic fan”) of pulling the air up and out—and that won’t work
unless another window is open to create airflow. But the only “window” into a holding tank is at
the end of a “hallway”—the vent line. If that “hallway” is too narrow and goes around corners,
takes a long and curved path, or rises more than 45 degrees above horizontal, no ambient air can
find its way to the tank to dissipate and exchange itself with the gasses in it.
The tank vent line should be as short, as straight and as horizontal as possible, with no sags, no
arches and no bends. The minimum I.D of the hose (which is the “standard” size in use today,
but for no reason other than being “standard” in fresh water and fuel tanks) is 5/8”; we
recommend that it be at least ¾”. Ideally, it should be no more than 3’ long. If it has to be longer
or if running the vent line uphill more than 45 degrees off horizontal can’t be avoided or if it’s
impossible to run a vent line that does not go around a corner, increase the size of the vent line to
1” or even larger. If, for instance on a sailboat, the line must go up to the deck, install a second
vent line in order to create cross ventilation or install some mechanical means of forcing air
through the tank. We prefer to put holding tanks in the bow of sailboats—under the v-berth—
because the hull just behind the point of the bow is the only place on the hull except the transom
that will never be under water even when the boat is at maximum heel; it’s the perfect place to
install vent-line thru-hulls, because the thu-hull is always into the wind, forcing air into the vent
line, when the boat is underway or on an anchor or mooring. The vent thru-hull should not be
the same type as a fuel vent thru-hull (a cap with a slit in it), but should be a should be a straight
open bulkhead type thru-hull. On sailboats especially it’s advisable to vent off the top of the tank
and not the side, because heeling can cause the contents of a half-full or more tank to run into the
vent line.
Because a filter blocks the flow of air into the tank, install a vent line filter only as a last resort;
the filter does trap the gasses which try to escape through the vent line, but a filter will not stop
gasses from forming, and therefore from going back up the inlet hose into the boat or up the
outlet hose—and eventually permeating even the best hose.
Check the vent line regularly for blockages; little insects love to build nests in them. And
remember—the vent line is not an “overflow!” So try never to overfill the tank—and if you do,
backflush the vent line thoroughly with water to remove any bits of sewage can clog it. It’s
possible for enough air to pass through it to allow the tank to be pumped and gasses to escape,
but that doesn’t mean the line is completely clear of any blockage.
Finally, the system, including the tank, should be at least nominally rinsed, through the head or
back down the deck fill—with fresh or salt water—after each pump-out and occasionally with
fresh water. (If your marina doesn’t have a dock water hose for this purpose, please ask them to
install one. It should be separate from the potable water hose and the two hoses should never be
interchanged.)
