APPENDICES
Your Cowater Flush Tank & Haul® System
Your Cowater Flush Tank and Haul® System
is a small vehicle haul system that has been
designed to provide running water, and safe
sewage and greywater disposal. The system
consists of the following components:
WATER SUPPLY
The system provides a fresh water storage
tank in your home to receive and store fresh
water. This tank has a hinged cover to permit
filling with a bucket for self haul. It is also fitted
with fill and overflow pipes to the outside for
use with the haul tank. Your system includes
a small pump and pressure tank to provide
pressure to the water supply system and a
long life washable filter.
SEWAGE COLLECTION
© COWATER ALASKA INC.
Your system is a "Gravity System". In this system, the sewage flows from the house to the
sewage holding tank by gravity. The outside
sewage holding tank is a superinsulated tank
to store sewage until it is hauled away. The tank
has a float switch inside to indicate when the
tank is full and must be emptied. This may be
as often as once a week or once a month, depending on how much water the family uses.
OTHER FEATURES
The system provides a high level of service using a very small amount of water. The Inax toilet
uses only about one pint of water per flush. A
hot water heater has been installed with your
system.
HAUL VEHICLES
Water and sewage haul tanks are provided to
haul fresh water to the house and sewage from
the house to the disposal site. The haul system
is operated by the community government which
normally charges users a fee for service.
The Gravity System
Page 2
THE COWATER FLUSH TANK & HAULTM SYSTEM
Typical Gravity Tank Installation
open pipes. As will be explained later, the seal
to keep odors from coming out of the toilet is
the small amount of water held in the toilet flap
in the bottom of the toilet bowl.
All fixtures connected to the sewage line and the
sewage tank itself are vented through a vent pipe
that goes out through the roof. You may not see
this vent pipe because it may be hidden inside
the bathroom plumbing wall.
The control panel in the above diagram has a
green light labelled "Water Pump Voltage" which
should be lit most of the time. If your sewage
holding tank gets full the red light labelled
"Sewage Tank Full" will light up and the green
light will go out. This means that the power to
the water pump has been cut off. The water
pump will not work until the sewage tank is
emptied.
There are traps (U shaped pipes) which hold a
small amount of water under each of the fixtures
except the toilet. The water in these traps provide a seal so odors from the sewage system
do not come up the drains into the house. If any
of these drains are disconnected the pipe leading to the sewer must be completely plugged to
prevent odors from coming in through these
There are heat trace cables in the sewer line
leading from the house to the sewage tank and
in the sewage tank. These should be turned on
in very cold weather to prevent freeze up in the
line or in the tank. When these are turned on,
the switch handle on the control panel lights up.
If the switch does not light, the heat trace may
not be working and you should have it tested.

The diagram above shows a typical "Gravity
Tank" installation. The toilet is installed directly
onto the main sewer connection to the sewage
holding tank. The drains from the other fixtures
such as the bathroom sink, bathtub, shower, and
kitchen sink are piped into that main sewage line
as well (shown as Greywater in the above
diagram).

THE COWATER FLUSH TANK & HAULTM SYSTEM
The Components Of Your Water System
A fiberglass fresh water tank is provided. It has
fill and overflow pipes that go outside so it can
be filled using the water haul tank. The tank has
a hinged cover for filling it by bucket.
A water pump is mounted on top of water tank.
Information on this equipment is included in the
Appendices. When plugged in, the pump will run
until the proper pressure is built up in the water
system. The pump will then shut off automatically. The pressure tank holds about 3 gallons
of water that is available for use before the pump
comes on again. Therefore, the pump does not
need to start every time you open a tap.
Trouble Shooting
If there is no water when you open a tap and the
pump does not run or the pump runs continually
but there is no water at the taps, check the following:
(i) Is the water tank out of water?
If it is, unplug the pump until the water tank is
filled then plug it in to restart it.
(ii) Your sewage holding tank may be full.
When the sewage tank is full, the float switch in
the holding tank will shut off the power to the
water pump. If this happens, the red light on the
control panel marked "Sewage Tank Full" will be
lit and the green light marked "Water Pump Voltage" on the control panel will go out. To correct
this, have the sewage holding tank emptied.
(iii) There may be an airlock in the system.
Open a tap for a few minutes and plug in the
pump to release the airlock. If this does not work,
check the water tank, pump, and pressure tank
connections. If a clamp has become loose, air
may be drawn into the system and prevent it from
working properly.
DRAINS FOR DRAINING YOUR SYSTEM
Spigots and/or plastic pipe with hose clamps
have been installed at low points in the house
water system so that the pipes can be drained.
If the house is to be vacated during the
winter, the entire system must be drained
or it may freeze and break.
WATER PUMP SHUT-OFF
When the sewage holding tank is full the power
to the water pump will be disconnected. The
Sewage Tank Full light on the control panel will
come on and the Water Pump Voltage light on
the control panel will turn off. When the sewage holding tank is emptied, power will be restored to the water pump.
WATER FILTER
The sediment filter has a clear plastic case for
inspection. The reusable screen must be
cleaned when dirty. Two methods may be used
(i) Close the valves, hold the filter top firmly and
unscrew the filter cover. Remove and rinse the
screen with clean water and replace. A mild
bleach solution may be used to wash the filter.
(ii) Backwash the filter. To do this reverse the
flow through the filter using the two valves. Hold
a pot under the valve and open the valve at the
bottom of the filter to backwash the screen.
DISCONNECTING TANK TO CLEAN
The water tank should be inspected and cleaned
periodically. The tank can be cleaned either in
place or it can be removed and cleaned outside.
To clean the tank in place, empty most of the
water out of the tank then follow the instructions
in the next section for cleaning and disinfecting the water system.
You should also check with your haul service.
They may have equipment and/or people who
can clean and disinfect your tank.
To remove the tank, disconnect the fernco couplers on the water fill and overflow pipes, and
remove the water pump. Alternately the pump
can be left in place and the water hose disconnected where it joins the pump.

WATER TANK, PUMP & PRESSURE TANK
Drinking Water Precautions
All water supply parts are selected to be safe
for drinking water. The system will provide
water which is safe to drink provided that the
following conditions are met:
Conditions
1. The source of water must be safe to drink.
If the water is obtained from a public water point such as a well or water treatment
plant the water should be safe to drink.
Putting water into your water tank
from any source other than an
approved drinking water source is not
recommended!
2. In a public building, samples of water in
the water storage tank must be tested periodically to ensure potability. This should
be arranged by the owners with the authorities who test the water at the
waterpoint.
Precautions
1. Hoses and connections used to transfer
water into the haul tank at the watering point
and into the water storage tanks at the
buildings or home must be kept and used in
a hygienic manner at all times. The following
procedures should be followed:
• Hose ends should always be rinsed before
connecting them to fill the haul tank and never
come into contact with contaminated objects.
© COWATER ALASKA INC.
• The ends of hoses on the water haul tank
should be connected (male end into female
end) to form a closed loop after use to prevent contamination.
• Exposed ends of pipes must be protected
from contamination with suitable caps or
covers.
2. Water Storage Tank and Filter. The water storage tank must be inspected regularly
for contamination and the following precautions taken:
Page 6
• Tank access: In homes with children or in
public buildings the tank lid should be protected so that children or the public cannot
have access to the tank interior. It should be
placed in a separate room or the lid should
be locked with a padlock.
• Inspection and cleaning: The tank should
be inspected and cleaned at least twice a
year. The frequency of cleaning will depend
on the condition of the water that is put into
the tank. To be kept safe for drinking, after
each cleaning the tank and the suction hose
to the pump should be disinfected. This can
be done by scrubbing with a solution of five
or six ounces of household bleach in five
gallons of water and left for a half hour. It
should then be thoroughly rinsed before being refilled. When reassembling the parts do
so only after carefully scrubbing hands.
• Disinfecting the piping system: The water pipes in the house can be disinfected
when the water tank is cleaned and
disinfected. To do this, pump some of the
bleach solution used to clean the tank through
the system and out the taps.
• In public buildings, the water in the storage tank should be tested with the same frequency as the potable water supply for the
community is tested.
• Water filter. The water filter should be inspected and cleaned monthly.
3. Disinfection after construction. Construction specifications call for the water system to be disinfected after construction, before use. It should be confirmed that it was
done.
SPECIAL NOTE: If the conditions and
precautions above are all met, the water
is safe to drink. If the conditions and precautions are not all met, a notice NOT
FOR DRINKING should be posted at
each fixture.
THE COWATER FLUSH TANK & HAULTM SYSTEM
The Sewage System
THE SEWAGE HOLDING TANK
(iii) Water Pump Voltage Indicator
The sewage holding tank collects the waste from
all water using fixtures in your house. This tank
is sealed so odors from the waste cannot escape. It is vented through the discharge pipe from
your toilet through a vent pipe hidden in the wall
which goes up through the roof. Greywater flows
into the system behind the toilet and uses the
same vent as the outside tank.
A green light on the control panel shows when
there is power to the water pump. If this light
is out, the pump has no power and can't run.
This normally means the sewage holding tank
is full (red light) is on. If the red "Sewage Tank
Full" is not on and the pump won't run, check
if the circuit breaker bringing power to the
pump is tripped. If it is not, there may be
something wrong with the pump.
A special Cowater designed and manufactured
control panel is installed on the bathroom wall
above the toilet. In normal operation the red
"Sewage Tank Full" light should be out and the
green "Water Pump Voltage" light should be on.
The control panel for your system works as
follows:
(i) Outside Holding Tank Full
When the outside sewage holding tank is full,
the red Sewage Tank Full light comes on. This
tells you that the holding tank should be pumped
out. At the same time, the power to the fresh
water pump is disconnected and the water pump
will not run to prevent overfilling of the sewage
holding tank. The toilet will continue to work for a
while because water is stored in the toilet water
tank. The Amtrol pressure tank will also give an
additional one or two gallons of water before it
loses its pressure.
(ii) Heater Switches
The sewage discharge pipe from the house to
the sewage holding tank and the sewage holding tank are protected with 3 watt per foot heat
tape. Switches to turn the pipe and tank heaters on are on the control panel. The tank heater
does not normally have to be turned on unless
an extended period of very cold weather is anticipated. The pipe heater should be turned on
when the outside temperatures falls below 15
degrees Fahrenheit.
TOILET DISCHARGE
Waste from the toilet flows down the sewage
discharge pipe by gravity. It is therefore important to fill the toilet bowl partially full with
water prior to defecating or using toilet paper.
The water will help to carry the waste to the
outside holding tank. If the toilet becomes
plugged, open the toilet flap by pulling the
large lever forward and use a regular toilet
plunger to push water down the pipe to clear
it.
VALVES
Unlike systems previously installed in your
community, in your system, the sewage holding tank has no valves. This means that the
sewage tank can only be emptied by using a
vacuum based haul tank.
LEVELLING
When your system was installed, the sewage
holding tank was carefully levelled. It should
be checked regularly and relevelled if it is
heaved by frost or other causes. A mark has
been placed on the holding tank and a corresponding mark has been placed on your
house. To check if the tank has shifted, use a
straight board to connect these two marks and
check if the board is level. If you don't have a
level, you can set a nearly full glass of water
on the board and see if the surface of the
water in the glass is the same distance below the rim of the glass all around the glass.

CONTROL PANEL
Pint Flush Inax Toilet
This is a high quality toilet that uses very little
water. If it is properly cared for, it can provide
excellent service to its owners for many years.
It is one of the most important components of
your Flush Tank & Haul® system.
The parts of the toilet can be seem in the diagram below. The purpose and the method of use
of the various parts is explained below.
Inlet Water Valve
The inlet water valve is a float valve that releases
water into the toilet water tank after water is used
for flushing. It is controlled by the float.
Overflow Pipe
The float which controls the water level in the
water tank should be adjusted so that the water
level is always a little below the overflow pipe.
The overflow pipe provides protection against
overflowing the toilet water tank onto the floor.
Drain Valve
The drain valve is used to empty the toilet water
tank. It is very important that the water be drained
from this tank if the building is going to be left
empty for any length of time in cold weather to
ensure that there is no water in the tank to
freeze.

The Parts Of The Inax Toilet
Page 8
THE COWATER FLUSH TANK & HAULTM SYSTEM
Pint Flush Inax Toilet (con't.)
Toilet Water Tank
Large Operating Lever
The water tank stores water for flushing. It will
hold enough water for a number of flushes so
the pump will not need to supply water for each
flush of the toilet. It needs to be emptied and
cleaned regularly to avoid build up of material
that will interfere with its operation.
The large operating lever controls the toilet
flap. The location of the flap valve and the
large lever are shown on page 10.
Toilet Flap
Use a toilet brush and liquid cleaner to clean
the toilet bowl. Scrub the bowl with the brush.
Never use boiling water or harsh abrasives.
The flap valve opens to let the wastewater out
of the toilet bowl into the sewer pipe.
Cleaning The Toilet
(i) Toilet Bowl
(ii) Rubber Seal and Flap
Flap Cable Assembly
The cable is connected to the large operating lever. It opens, closes and locks the toilet
flap.
Small Operating Lever
The small lever lifts the flush ball in the water
tank to allow water to flow from the tank into
the toilet bowl.
Rubber Flap Seal
The rubber seal at the bottom of the toilet bowl
allows additional water to be retained if the
toilet flap is locked in position.
The black rubber seal and the flap at the bottom of the toilet bowl should be throughly
cleaned regularly - we suggest once a week.
This will ensure that the bowl will hold water
when the flap is locked back. To clean the seal
and flap, pull the large handle forward.
The diagram below shows the way the rubber seal should be cleaned. A toilet brush is
supplied and it should be used regularly to
clean mineral deposits and other waste from
the seal and the flap. Both seal and flap should
always look black.
To reduce staining the toilet bowl,
two strips of toilet paper should
be laid on the water surface
before defecating.
Cleaning The Rubber Seal

Water Surface
Pint Flush Inax Toilet (con't.)
If white mineral deposits appear on the seal
or flap you need to increase the cleaning effort. Also you may put a quarter cup of vinegar into the toilet overnight once a week.
(iii) Toilet Water Tank
To clean the water tank, turn off the water supply to the toilet, and then drain the water out of
the toilet tank by opening the valve at the bottom of the toilet water tank, or by using a sponge
to soak up the water.
Gently clean the inside of the toilet water tank
with a long handled brush. After cleaning,
close the drain valve and turn on the water
supply to refill the toilet tank.
Operating The Toilet Handles
© COWATER ALASKA INC.
Position 1 is the normal position of the Inax
Toilet when not in use. In this position the
hinged flap is relaxed and engages the upper
bowl with enough tension to hold a small
amount of water, enough water for urinating.
Then, you need only pull the large handle forward for a second to let the urine pass into
the sewage tank and replace it with a small
amount of clean water on the toilet flap. After
use, the handles will automatically return to
Page 10
the normal position if you just let go of them.
Before using the toilet for a bowel movement,
more water should be let into the toilet bowl.
First, you lock the flap valve in place against
the rubber seal so it can support additional
weight by pushing the large handle back until
it clicks. Add water to the toilet bowl by holding the small lever forward. When sufficient
water (2 to 3 inches) has gone into the bowl
release the small lever. It can help to avoid
staining of the toilet bowl if you also lay two
pieces of toilet paper on top of the water in
the bowl before using the toilet for a bowel
movement.
After using the toilet, pull both small and large
levers forwardÛ to flush the waste into the
sewer. Then, release the levers and they will
return to their normal position 1. A small
amount of water will automatically remain in
the saucer of the hinged flap at the bottom of
the toilet to prevent any smell from escaping.
The large lever should not be left in the locked
back position 2 when the toilet is not in use.
This puts unnecessary strain on the flap cable assembly and the parts in it.
THE COWATER FLUSH TANK & HAULTM SYSTEM
SPECIAL NOTES
USE AND CARE OF THE INAX TOILET
1. DRY FLUSHING CAUSES
CLOGGING
The diagram below shows what
happens if you don’t use enough
water to flush solids.
It takes water to flush the waste and
toilet paper down the sewer and out
into the holding tank.
DO NOT DRY FLUSH!!
3. TOILET PAPER
A normal amount of toilet paper can be
flushed down the toilet. Do not put toilet
paper in a basket in the bathroom. That
is unsanitary.
4. WHAT GOES INTO THE
TOILET?
• Human waste and toilet paper ONLY.
Follow these instructions:
• Lock the large lever back.
• Add at least 3 inches of water to
the bowl using the small lever.
• Lay two strips of toilet paper on
the water.
• Use the toilet. Put toilet paper in the
bowl.
• Flush the toilet. The water will carry
the waste to the sewage tank.
• DO NOT put diapers, tampons or
sanitary napkins in the toilet.

2. PROPER FLUSHING
SPECIAL NOTES CONT.
5.CLEANING THE TOILET
7. FLUSH BALL
The toilet should be kept as
clean as the dishes in your
cupboard. We recommend a
good cleaning once a week.
Check the flush ball in the tank to
make sure it lifts properly. Adjust the
chain if necessary. If dirt or algae has
collected on the ball, clean it with a
small brush.
Follow these instructions:
• Toilet Bowl:
Use a toilet brush and liquid cleaner
to clean the toilet bowl. Scrub the
bowl gently with the brush until it
shines. Never use boiling water or
harsh abrasives.
• Rubber seal and Flap:
See page 9 for instructions. The
rubber seal at the bottom of the
toilet must be soft and black. Mineral deposits must be removed or
the seal will get hard and break the
flap’s cable mechanism. This is
very expensive to replace. Cleaning
this seal cannot be neglected. Make
sure you brush the backside of the
rubber seal as shown on page 9.
© COWATER ALASKA INC.
6. TOILET TANK
Algae and minerals such as sand
and other material may collect in the
tank and prevent proper functioning.
Lift the cover and inspect the tank
every month or so. Clean the tank if
necessary.
Page 12
THE COWATER FLUSH TANK & HAULTM SYSTEM
8. RIM HOLES
Water flows into the toilet around the
rim of the bowl. It enters through two
holes in the rim at the back and one
hole at the front. If the water is hard,
the rim holes may become blocked
with minerals. If the water flow is
slowed down or stopped the rim
holes may be blocked. You may
clean the opening by using a small
length of wire.
The outside sewage holding tank may be located underneath a building that is high
enough off the ground, or beside the building.
Regardless of the location, all sewage holding tanks have been constructed with the
same internal components.
The tank heat tape is powered independent
of the discharge pipe heat tape. If the heat
tape ever burns out or requires replacing, the
old heat tape should be withdrawn at the first
junction box and the new heat tape inserted
and pushed through the copper tubing.
The tank which holds the sewage is made of
stainless steel. This tank is insulated with
urethane foam and set inside a plywood box.
Similarly, if the mercury float switch ever requires replacing, there is an access port in
the top of the tank above the float switch, the
mercury float switch must be disconnected at
the front junction box, and the float switch removed through the access port. The wire for
the new float switch would have to be threaded
through the conduit and the float switch installed as per the figure on Page 2.
ELECTRICAL CONSTRUCTION
The diagram above illustrates the electrical
construction of the outside sewage holding
tank. The wiring for the float switch, tank heat
tape, and receptacle to plug in the blower is
contained within the construction of the sewage holding tank box as illustrated.
The tank heat tape is 3 watts per foot and terminates at the first junction box. In the larger
tanks, two heat trace cables are provided.
Mercury float switches are known to be very
reliable, so it is unlikely that a float switch will
ever require replacement.

Winter Storage Precautions
If a home or building is kept below 62 degrees
or is left unoccupied and unattended for any
period of time in the winter, it is absolutely necessary that the following steps be taken to ensure that all parts of the system are protected
from freezing and breaking pipes, pumps, or
tanks. The homeowner should request assistance from the system operator and maintenance person.
8.
If available, you may use air pressure to
blow all water from the water piping.
9.
Leave all valves open until the system is
ready to be used again.
10. Do not forget to drain the rainwater tank.
SEWAGE SYSTEM
1.
Post a note on all fixtures warning people not to use the fixture. Include the date
and name of the person who should be
contacted for further information.
WATER SYSTEM
1.
Empty the water storage tank.
2.
Turn on all fixtures. When no water runs
from any of the fixtures, unplug the water
pump.
2.
All P-traps in bathtubs, showers or sinks
must have a cup of antifreeze (Propylene
Glycol) placed in the drain.
3.
Remove the pop-off fittings at the water
pump.
3.
4.
Drain all water lines by opening all
valves and low point cocks. For some
of the older systems you may have to
disconnect plastic pipes at low points
and disconnect the flexible hose from
the toilet.
If the system has a transfer tank, turn on
the blower switch and empty the transfer
tank.
4.
Transfer tanks have two inches of sewage in the bottom which is not removed
by the blower system. Antifreeze
should be poured into the toilet to prevent this sewage from freezing and
breaking the tank. Check the antifreeze
directions and use an amount to protect
five gallons of liquid.
5.
Remove the clear filter cover from the
water filter and drain it.
6.
If you have an Inax toilet, open the drain
valve on the toilet tank. Take the top off
the back of the toilet and visually check
to ensure that the water was able to
drain. Any remaining water can be
soaked up with a sponge.
© COWATER ALASKA INC.
7.
If a hot water heater is connected to the
system, first turn off the electrical switch
or circuit breaker. All water must then
be drained from the hot water tank.
Attach a garden hose to the drain on
the hot water heater and drain outside if
practical. Otherwise drain into a container inside the house. Remember to
open the pop-off valve and to leave it
open while draining the heater.
Page 14
5. Call the office and request that your
sewage tank is pumped out. Follow up
to ensure it is done.
ELECTRICAL
1 . Label the wall switch or the circuit
breaker switch for the hot water heater
with a warning that the hot water tank
must be filled with water prior to turning
the electricity back on. Failure to do
this could result in a burned-out hot
water heater.
2.
Turn off and label all circuit breakers,
with a dated warning to leave off. Include the name of the person to be
contacted for information.
THE COWATER FLUSH TANK & HAULTM SYSTEM
Troubleshooting Guide
Following are some of the most common problems that might be experienced with your system.
Water Pump Will Not Start After It Has Been
Unplugged
• The sewage holding tank may be full. If the
red "Sewage Tank Full" light on the control
panel is on, have the sewage tank emptied.
• There may be an air lock in the water line.
Open a tap and if the pump starts let water
run for about 15 seconds.
• Check to see if there is power at the pump
receptacle and at the control panel.
Water Pump Does Not Shut Off
• Water tank is empty. Unplug the pump until
the water tank is filled.
• There is an airlock in the system. Open a
tap until water flows to release the airlock.
One of the water tank, pump, or pressure
tank clamps is loose. Tighten the clamp.
Water Faucets Drip
•
Water Not Stored In Toilet Bowl On Top
Of Flap Valve When You Add Extra Water
• The large toilet lever is not clicked back.
• The black rubber seal at the bottom of the
toilet or the flap is dirty. Clean with toilet
brush. Remove deposits.
• Toilet levers or flush cable need adjusting.
Call maintenance person.
Water To Toilet Fails To Stop Running
• This indicates that the flushball in the water tank which is controlled by the small
lever is not closing properly. Remove
the toilet tank cover and inspect the
linkage for proper functioning.
• Check to see if a foreign object or dirt has
lodged in the flush ball to prevent it from
seating.
Sewage Backs Up in Toilet,
Toilet leaks onto Floor.
Washers require replacing.
• The sewage holding tank is full. Empty tank.
Indicator Lights And Switches On

Overflow in Toilet Tank
Filling the Water Haul Tank
Make sure to read and observe all of the
drinking water precautions set out on page
6 with regard to handling of the hoses, etc.
Following are instructions for correct operation
of the Cowater water delivery system.
1. Take the haul vehicle and get the water haul
trailer. Leave the outlet valve open until reaching
the pumphouse. Fasten the blower securely in
place and be sure that hoses and extension
cords are secure.
2. Drive to the pumphouse and park the haul tank
close to the pumphouse water hose.
3. Remove the blower fitting adaptor. Put the
pumphouse hose into the haul tank and turn on
the water. Allow a little water to run out of the
tank outlet before closing the outlet valve. This
will ensure that the outlet pipe is clean and that
the valve is thawed out in cold weather.
4. Close the outlet valve and fill the tank. Be prepared to turn off the water when the water tank
is full.
5. Replace the blower fitting adaptor, and place
the dust cap on the fitting. There should always be a dust cap on this fitting to prevent
contamination from entering the water tank.
6. Ensure that blower hoses and extension
cords are secure and drive to the first house to
be filled.

The Water Haul Tank
Storing the Water Haul Tank
If the haul tank is to be left for any period of time,
it must be thoroughly drained. Any remaining
water in the haul tank must be drained with the
back of the trailer kept low. The water hose must
Page 16
be thoroughly drained by disconnecting and progressively raising the entire length of the hose
until all of the water has run out.

Delivering Water to the House
2. Connect the blower hose to the blower fitting adaptor. Plug the blower into the GFI protected outlet on the house or the sewage holding tank.
3. Open the outlet valve on the haul tank. Turn
the blower on and ensure that water is flow
ing to the house. Watch the overflow pipe care
fully.
4. As soon as water flows from the overflow
pipe turn the blower off.
5. Disconnect the air hose. Disconnect the
water delivery hose from the house taking
care not to let the hose ends touch anything
that may contaminate them. Connect the two
ends of the hose together to prevent
contamination of the hose while travelling and
place it on the hose rack on the trailer. In warm
weather you may connect the hose end to the
camlock fitting.
6. In cold weather, the water tank should be
drained of all remaining water: (i) close the
outlet valve, (ii) disconnect the water delivery
hose, and (iii) open the outlet valve to drain
the tank, with the back of the trailer kept low.
7. Drain the disconnected water delivery
hose.
8. Coil the water hose on its rack. Coil up the
extension cord. Ensure that all hoses and
cords are secure. Drive back to the pump
house for the next load.

Emptying The Sewage Holding Tank
Always wear protective clothing (coveralls,
gloves, and rubberized shoes) when
operating the sewage haul equipment. This
clothing should be used only for this
purpose. It should be removed and hands
should be thoroughly washed before eating
or going on to other work.
hose will become light and you will hear the
vacuum blower motor change its tone and run
faster when the holding tank is empty. Turn off
the vacuum blower. You must watch the sight
glasses on the haul tank. If you over fill the tank,
the vacuum will suck sewage into the blower.
1. Park the sewage haul tank near the tank to be
emptied. Ensure that the dump hose is securely
attached to the cap on the trailer. A safety strap
should hold the dump hose securely in place to
ensure no sewage escapes from this hose.
5. Make sure the sewage fill hose is empty of
sewage by lifting it in the center for a couple of
seconds so that all sewage is drawn out of the
hose. It is important to completely empty the
sewage hose before disconnecting it in
order to avoid spillage.
2. Open the door on the sewage holding tank,
un-cap the sewage connection and connect the
sewage fill hose.
6. Disconnect the sewage and blower hoses.
Replace the camlock cap on the sewage
holding tank, and close the door.
3. Connect the vacuum blower hose to the air
valve on the haul tank. Plug the vacuum blower
into the electrical outlet on the sewage holding
tank and start the vacuum blower.
7. Cap the sewage hose and coil it on the rack
so sewage cannot leak out while you are travelling to the lagoon. Ensure that the blower and
cord is secured to the haul vehicle.

Dumping the Sewage
1. Drive the haul trailer to the lagoon alongside
the dump point with the back end of the trailer
lower than the front .
2. Detach the dump hose from its attachment
cap. Lay the dump hose on the ground so that
the sewage runs into the lagoon. The dump hose
should be handled with caution as the sewage
may splash if dropped prematurely.
3. Open the air valve on top of the tank.
4. When the tank is empty, reattach the dump
hose to the attachment cap, secure it with the
safety strap. Close the air valve.
5. Go to the next tank to be emptied. It is important that loads be dumped after each house so
there is no risk of overfilling the haul tank. Never
empty two household tanks in one load.
