EMERGENCY WATER
|

American Survival Guide Vol. 13, No. 4
|
|||
|
|
|||
|
To the surprise of many, the need for water is much higher
|
|||
|
than for food. Many people have lived for 30 days with no food,
|
|||
|
but without water, after three or four days you are in serious
|
|||
|
trouble.
|
|||
|
People tend to underestimate how much water is actually needed
|
|||
|
to perform normal, routine tasks of daily living.
|
|||
|
Drinking water is the primary need, but you may need
|
|||
|
additional water for baths, cooking, flushing toilets, cleaning
|
|||
|
eating utensils, washing clothes and other chores.
|
|||
|
Water availability is affected in natural and man made
|
|||
|
disasters. In every disaster, the majority of the general
|
|||
|
population is totally unprepared for even a small interruptions in
|
|||
|
normal utility and food distribution services. In most disasters,
|
|||
|
the victims expect and sometimes demand that "someone" provide
|
|||
|
needed protection, water, shelter and food.
|
|||
|
There are myriad ways the water supply can be disrupted. The
|
|||
|
most common way is due to lack of electricity. With no
|
|||
|
electricity, there will be no water from water purification plants
|
|||
|
or your well--unless it is a non-electric well.
|
|||
|
The second most common way is a water main rupture. Recently,
|
|||
|
more than 10,000 people in the southeastern United States were out
|
|||
|
of water for over two weeks due to such a rupture.
|
|||
|
Wells can be contaminated by flooding, and well pumps can
|
|||
|
become damaged by flooding. Freezing weather also takes its toll
|
|||
|
on well and city water lines.
|
|||
|
Local streams are never safe during disasters because raw
|
|||
|
sewerage and polluted surface water can enter the streams.
|
|||
|
During a recent hurricane , the wind blew an excessive amount
|
|||
|
of leaves into the affected area's reservoirs. The water turned
|
|||
|
yellow for three weeks and acquired an objectionable taste due to
|
|||
|
the abnormal amount of leaves that were decomposing.
|
|||
|
Container storage -- certain plastic containers such as
|
|||
|
drywall buckets and plastic trash containers are not intended for
|
|||
|
food contact and may leach undesirable chemicals into stored water.
|
|||
|
These containers should be used for transporting water or for
|
|||
|
storage of water not used for consumption.
|
|||
|
Although the 5 gallon drywall bucket is not good for storing
|
|||
|
drinking water, it is an excellent choice for transporting water
|
|||
|
and for storage of water not used for consumption.
|
|||
|
Any container used for transportation or for storage needs a
|
|||
|
top. during transportation, the top reduces spillage. Tray
|
|||
|
transporting water in the care trunk in a bucket without a top and
|
|||
|
you will see how much sloshes out. During storage, the top keeps
|
|||
|
out dirt, dust, insects, etc.
|
|||
|
The 5 gallon buckets used by restaurants for food products are
|
|||
|
excellent for storing drinking water. If no containers are
|
|||
|
available, plastic sheets or bags can be used to line porous
|
|||
|
containers for storing water in emergencies. A depression can ever
|
|||
|
be dug in the ground and lined with plastic to hold water
|
|||
|
temporarily.
|
|||
|
In storing water for emergency uses, most authorities
|
|||
|
recommend a minimum of 2 gallons per person per day. This should
|
|||
|
include one half gallon for drinking and the balance for other
|
|||
|
uses. It is preferable not to ration water in a survival situation
|
|||
|
because this may have adverse affects on the health of people
|
|||
|
involved.
|
|||
|
I store non-drinking water for dishwashing, toilets, washing
|
|||
|
clothes, etc. in 5 gallon plastic drywall buckets. My drinking
|
|||
|
water is stored in out bleach bottles and plastic milk jugs. I add
|
|||
|
16 drops of liquid bleach (4-6 percent sodium hypochlorite) per
|
|||
|
gallon of clear water to protect it during storage form the growth
|
|||
|
of micro-organisms. I suggest storing an extra jug of bleach to
|
|||
|
purify any new water that is of questionable quality.
|
|||
|
Be careful not to misidentify bleach bottles as containing
|
|||
|
drinking water if you also have bleach on hand. This is especially
|
|||
|
dangerous where children are involved. Always remove the bleach
|
|||
|
label and replace it with the word "WATER" in large indelible
|
|||
|
letters on the jugs in which the water is stored.
|
|||
|
The Utah State University Extension Service offers the
|
|||
|
following instructions for heat sterilization when using glass
|
|||
|
containers to store water: "fill clean fruit jars with water,
|
|||
|
leaving one inch of head space at the top of the jar. Place clean
|
|||
|
sterilized lids on the jar and process the water in a boiling water
|
|||
|
bath as fruit juice is processed. Quart jars should be processed
|
|||
|
20 minutes. Two quart jars 25 minutes."
|
|||
|
Whatever the container used, it is probably a good idea to
|
|||
|
date each container with a large magic marker or other marking
|
|||
|
instrument. I'm glad I did mark my first water storage jugs because
|
|||
|
I now have water that is 8 years old. Water is used on a first-
|
|||
|
in first-out basis. My water supplies have been used many times
|
|||
|
in the last 8 years.
|
|||
|
Since I do own a generator, a power outage will shut down my
|
|||
|
well. No electricity, no electric well pump. On several other
|
|||
|
occasions, my well pump had maintenance problems and the stored
|
|||
|
water came in very handy while the pump was being repaired.
|
|||
|
Don't store plastic containers near fuels, pesticides or
|
|||
|
similar materials. The vapors from these can penetrate the plastic
|
|||
|
and contaminate the water. Also, store water in the dark to
|
|||
|
protect the plastic from sunlight.
|
|||
|
One problem commonly encountered in water storage is inventory
|
|||
|
control. You must be diligent in replacing the water you use and
|
|||
|
rotate your inventory at least every several years. Use the oldest
|
|||
|
inventory first. Any questionable water you have in storage can
|
|||
|
be used for non-drinking purposes.
|
|||
|
The local county extension service will test your water for
|
|||
|
purity. This is a good idea when you have water supplies that have
|
|||
|
not been rotated for several years.
|
|||
|
If you have enough advance notice of a coming water emergency
|
|||
|
or possible emergency, fill up extra empty mill cartons, jars,
|
|||
|
bathtubs, sinks, wading pools, trash cans and or any other
|
|||
|
available container. Obviously water in garbage cans would be used
|
|||
|
for non-drinking purposes unless filtered and purified.
|
|||
|
OTHER WATER SOURCES -- You can use the water for the toilet
|
|||
|
tank (not the bowl) and it will offer several gallons. You may
|
|||
|
want to look in your tank right now to see if it needs a good
|
|||
|
cleaning.
|
|||
|
Trapped water in house plumbing lines offers several gallons
|
|||
|
of clean water. As soon as the water pressure goes off, be careful
|
|||
|
to shut off your house lines from the street. This action will
|
|||
|
insure you do not draw in contaminated water or allow your trapped
|
|||
|
water to flow back into the connecting municipal system. Next,
|
|||
|
turn off the heat sources to your water heater. To gain access to
|
|||
|
trapped water in the house line, crack the faucet at the lowest
|
|||
|
level and drain the lines. I have installed a faucet in my
|
|||
|
basement to insure I can collect the water from the lines that run
|
|||
|
under my house. The basement is where I plan to be during a
|
|||
|
weather alert.
|
|||
|
Your water heater tank holds 30 - 40 gallons. Check your
|
|||
|
water heater tank because it may have a foot or more of sediment
|
|||
|
in the tank bottom. Sediment removal is a good reason to drain the
|
|||
|
tank every year. In addition, the removal of sediment will improve
|
|||
|
the water heater's efficiency. The hot water tank can be drained
|
|||
|
by opening the faucet at the bottom of the tank. You may need to
|
|||
|
open the hot water faucet elsewhere in the house to allow the
|
|||
|
release of the vacuum to allow a free flow of water. The water
|
|||
|
inlet valve (faucet) should be turned off if you doubt the quality
|
|||
|
of the inlet water. If the inlet valve is turned off, you may need
|
|||
|
to vent the water tank by opening the "pop off" valve lever that
|
|||
|
is used to allow over heated tanks to vent excessive pressure. The
|
|||
|
faucet at the bottom is threaded to receive a regular garden hose.
|
|||
|
The water in a water bed can also be used. Only use this
|
|||
|
water for non-drinking purposes because of the possibility of
|
|||
|
algaecide chemicals in the water and plastic chemicals being
|
|||
|
leached into the water.
|
|||
|
A swimming pool offers a large volume of stored water for non-
|
|||
|
drinking use. In one case a swimming pool provided a whole
|
|||
|
neighborhood with water after a hurricane. The neighbors set up
|
|||
|
a temporary shower in the backyard next to the pool. Others who
|
|||
|
lived nearby carried the water back home in any containers they
|
|||
|
could find.
|
|||
|
If it rains, place buckets or barrels under rain gutter down
|
|||
|
spouts. You may have to cut or disconnect them so the water can
|
|||
|
flow into the container. If your container is not clean, you can
|
|||
|
line it with plastic such as a clean garbage bag. Plastic sheets
|
|||
|
can be placed on a hillside or be strung between trees to funnel
|
|||
|
water into your containers.
|
|||
|
PURIFYING WATER -- Pollution can affect ice, snow, water in
|
|||
|
streams and in shallow wells causing these water sources to be
|
|||
|
unsafe. Even clear streams can have parasites in them. Unpolluted
|
|||
|
water must be boiled to assure complete destruction of any
|
|||
|
dangerous organisms.
|
|||
|
Properly stored water is the safest in an emergency. If you
|
|||
|
have to use water from an unknown source or of unknown quality, be
|
|||
|
aware that the following methods of purifying water do not
|
|||
|
guarantee the safety of the water but will reduce the risks
|
|||
|
involved.
|
|||
|
Boiling water is one of the safest methods of water
|
|||
|
purification. It should be boiled for at least 20 minutes to
|
|||
|
insure that bacteria are killed. Boiling does not remove
|
|||
|
pollution. The boiling process will make the water taste flat since
|
|||
|
some air has been driven out. To add back the oxygen and to
|
|||
|
improve the taste, pour the water several times from one container
|
|||
|
to another. Another method is to pour the water into a closed
|
|||
|
container and vigorously shake it. A small piece of wood or a
|
|||
|
pinch of salt can be added to the boiling water to improve the
|
|||
|
taste.
|
|||
|
Learn how to start an outdoor fire to be used in boiling
|
|||
|
water. Do not depend on electricity or gas for your heat source.
|
|||
|
Only use chemical purification for questionable water if
|
|||
|
boiling is not possible. Understand that organic matter in the
|
|||
|
water increased the amount of chemical needed. The colder the
|
|||
|
water, the more time needed for the chemical to work.
|
|||
|
Add 16 drops of bleach per gallon of water for clear water and
|
|||
|
double that amount for cloudy or sediment-filled water. Mix well
|
|||
|
and wait for 30 minutes before using. You should be able to smell
|
|||
|
the bleach after 30 minutes. If not, repeat the process until you
|
|||
|
smell the bleach, otherwise do not use the water. If you leave the
|
|||
|
container uncovered for several hours, the chlorine taste will be
|
|||
|
reduced and the water will be more palatable.
|
|||
|
Always use fresh liquid bleach because it will lose its
|
|||
|
strength over time. Double the recommended amounts if the bleach
|
|||
|
is over one year old and do not use it if over two hears old.
|
|||
|
Water purification tablets can be used to purify water. They
|
|||
|
are readily available from sporting goods stores and military
|
|||
|
surplus outlets.
|
|||
|
Use fresh tablets. Normal shelf life for iodine tablets is
|
|||
|
3 to 5 years if unopened. iodine tablets work better than bleach
|
|||
|
or halazone tablets for certain intestinal parasites.In addition,
|
|||
|
halazone tablets have a shelf life of only 2 year.
|
|||
|
Commercial filters combine a filter substance and active
|
|||
|
ingredients to filter and treat the water at the same time. Some
|
|||
|
brands are not as effective as they claim.
|
|||
|
Clear water should be used whenever possible when purification
|
|||
|
is needed. If sediment is present, it will settle out in time and
|
|||
|
the clear water can be poured off or the water can be poured
|
|||
|
through a cloth or coffee filter to speed up the process.
|
|||
|
A novel method to clear up water is to use a cloth siphon
|
|||
|
arrangement. Place the full cloudy water container higher than the
|
|||
|
empty clean water container. Roll up a clean dry piece of cloth
|
|||
|
and put one end in the upper container and the other end in the
|
|||
|
lower clean container. If the cloth in the lower container is
|
|||
|
several inches below the cloudy water's water line, then a siphon
|
|||
|
effect will begin and the water will be filtered. This is a very,
|
|||
|
very slow process, but is good to know about.
|
|||
|
In the distilling process, questionable water is boiled and
|
|||
|
allowed to condense into safe water.
|
|||
|
One method is to allow the water vapor escaping out of a tea
|
|||
|
kettle to enter an inverted milk jug. The water vapor will
|
|||
|
condense in the milk jug and run out into a pan set nearby to
|
|||
|
collect it.
|
|||
|
Another method is to run the water vapor through copper tubing
|
|||
|
(same as used in your house) to condense the vapor into pure water.
|
|||
|
For quantity production, try to visualize a moonshiners still. Use
|
|||
|
a larger closed container heated over a fire with copper tubing
|
|||
|
coiled several times to make such a still.
|
|||
|
CONSERVATION -- The more you conserve your water in an
|
|||
|
emergency, the less you will use or need from storage. For example,
|
|||
|
toilets use 3-4 gallons per each flush. Add several bricks in the
|
|||
|
tank to reduce usage (be careful not to have too much waste for
|
|||
|
each flush). And toilets need not always be flushed after each
|
|||
|
use. You might also want to build an outdoor toilet trench such
|
|||
|
as is described in "The Boy Scout Handbook" or other publications.
|
|||
|
Stretch out the periods between your baths or showers, or use
|
|||
|
a Navy type shower procedure, where you turn on the water to wet
|
|||
|
down, turn off water, soap up and then turn on the water to rinse
|
|||
|
off. If water is very limited, take a sponge bath when ever
|
|||
|
practical.
|
|||
|
Do not waste water washing clothing other than under clothing.
|
|||
|
Before you wash, leave clothes outside over night and they will
|
|||
|
pick up additional moister reducing the amount of wash water
|
|||
|
needed. A heavy dew will make a wash towel moist enough to use for
|
|||
|
a sponge bath. It is even better to roll the clothes in the dew
|
|||
|
to make them very wet before beginning the wash.
|
|||
|
Never throw water away without figuring out other uses for it.
|
|||
|
For example, use the tub water for flushing a toilet. Save the
|
|||
|
water when you wash your hands and use it for the initial clothes
|
|||
|
washing water.
|
|||
|
Do not dispose of dirty water just because it has sediment in
|
|||
|
it. You will be surprised how much sediment in dirty water will
|
|||
|
settle out over night or in several days if left undisturbed. The
|
|||
|
clearer surface water can be used again for non-drinking purposes.
|
|||
|
Finally , it is very important to wash hands when preparing
|
|||
|
food. Intestinal problems can rapidly dehydrate the body and cause
|
|||
|
severe health problems.
|
|||
|
As you can see, water storage is very simple to accomplish.
|
|||
|
A little advance preparation can add a great deal of security in
|
|||
|
our current water-sensitive and highly technological times as well
|
|||
|
as in any emergency situation.
