Water: Getting Started
Why This is Important
- Water is
our most essential nutrient. People can survive
days or weeks without food, but only about four
days without water. The body uses water for
digestion, absorption, circulation,
transporting nutrients, building tissue,
carrying away waste and maintaining body
temperature.
- Most household have water provided and treated by plants providing clean, non-contaminated drinking water. In the event of a pandemic, essential services such as water treatment may be interrupted for several reasons:
- Absenteeism of plant employees due to illness or fear
- Lack of electricity to run the plants
- Lack of products necessary to treat the water due to ill truck drivers or manufacturing plant workers.
How Much Water Should You Store?
Plan on having at least 1 gallon of
water per person PER DAY on hand. Most
people need 2 quarts of water per day for
drinking. The other 2 quarts in the gallon per
day are for cooking, bathing and cleaning.
Don’t forget your pets. A small pet can drink
one quart of water per day.
A large
supply of stored water is bulky and not
practical for everyone. One gallon of water
weighs about 8 ½ pounds. Many local pandemic
flu plans have water system restoration as a
top priority, although it may not be purified.
If you cannot store three months of drinking
water, do these two
things:
- Store AT
LEAST 2 weeks water. That's the bare
minimum and you should do it today! Store at
least 4 weeks if you have infants, elderly, or
immune-compromised household
members.
- Get the next best
thing – capability.
This could mean:
- Collapsible
containers: to be filled after pandemic
flu begins, before water service is
degraded.
- Water purification filters: to remove microorganisms from potentially contaminated water.
Of
the two, water purification capability is the
most important. Good drinking water will be
needed during and between each pandemic
wave.
Storage
Start NOW. If you use bottled
water, get extra when you shop. Food grade
plastic or glass containers are suitable for
storing water. Thoroughly rinse and clean your
containers and fill them up. Tap water is fine,
unless there are restrictions from the health
district.
Cautions:
1. Do not use empty milk
jugs. Bacteria in milk can become lodged
in the plastic of the jug. Additionally,
the plastic is too thin to last more than a few
months before leaking or breaking.
2. Do not store
your water near gasoline, kerosene, pesticides
or similar substances.
3. Water is heavy
- a 55 gallon barrel weighs about 460
pounds. Store your water where its weight
is adequately supported. Basements and
garage floors are great.
Clearly label all drinking water containers "drinking water" with the current date. Store the water in a cool, dry place away from direct sunlight and heat sources.
- If you have a
pool, you have a water source for cleaning and
bathing but NOT for
drinking. Water in swimming pools is
chlorinated, but it also contains chemicals
that can make it unsafe to drink.
Therefore, the EPA does NOT recommend drinking
it.
Water storage containers come in many shapes and sizes. You can purchase new 5-6 gallon plastic containers designed for water. For small spaces, consider storing foldable or collapsible water tanks which can be filled after a pandemic begins, and before utility services degrade or fail.
- If you have the
room, consider purchasing large plastic
drums. Make sure they are food grade
containers.
Also consider the small 'kiddie' pools that hold several hundred gallons of water. Keep the pool folded in its original box until it is needed. This water will require treatment using steps in the (See: ‘Emergency Purification’ section.)
NOTE:
Properly stored water does NOT go bad.
However, it may taste stale. To improve the
taste, just pour your water from one container
into another one. Do this several
times.

Water:
Finding and Filtering
Why This is Important
As your stored water is used up, you will need to find more water. Unless you have access to a close, reliable well, it will need to be both filtered and purified for safe drinking.Planning Ahead
- obtain a ‘well
bucket’. An example of this is at this
retailer's site (Lehman's -
search for ‘well
bucket’).
- obtain a short (about
two feet) section of threaded galvanized pipe
that will fit in the well casing. Cap the
bottom. Drill a small hole in the top and tie a
rope to it. Lower the pipe into the well, and
pull up after it fills.
This water will need to be treated before drinking, because the well will have contamination from being opened and the pump removed.
Alternative Water Sources
- Rainwater
- Streams and rivers
- Ponds and lakes
- Natural
springs
These will likely have contamination; regardless of how "clear" the water looks. Be sure to:
- Filter
this water. This is to remove Giardia and
Cryptosporidium
- Treat this water by boiling or chemical disinfection. See “Emergency purification” for detailed instructions.
Filtering Water
The ‘Gilmore’ 2-bucket System. This system is very simple and can be made in 10 minutes. It is easy to store and requires no mechanical skill. Except for the filter, all materials can be found locally, and the buckets are often free from bakeries. This is an excellent project for someone new to preparing.The following is a home-made water filtering system courtesy of 'Gilmore.' This filtering system will remove microorganisms EXCEPT viruses. USE CHLORINE (OR BOILING) TO GET RID OF ANY VIRUS THAT MAY BE IN YOUR WATER! Filter your water using this system first, THEN use the chlorine (or boiling) for purification.
Two (2) five gallon FOOD GRADE buckets, a Berkey Big Black water filter, and optional spout.
The Berkey filters cost about $59 each or $99 for two. To find them, search the internet for "Berkey replacement filters." The filters can be cleaned with Scotch-Brite cleaning pads. Each filter will process about 3000 gallons. Strain water beforehand if there is visible debris or if using pond or puddle water.
Assembly Instructions:
One lidded bucket will be placed on top the other lidded bucket. The top bucket will hold the unprocessed water, and the bottom bucket will catch the water that has been filtered.- Find a drill bit
just slightly larger than the stem on the
filter. Set the bottom of one bucket on one of
the lids. Mark the center of the bucket bottom.
Drill a hole through the bottom of the bucket
and the lid that it is on. These holes allow
the stem of the filter to pass through the
buckets, but will keep the body of the filter
from slipping through.
- Remove
the nut from the Berkey replacement filter
stem.
- Place the bucket with the
hole in the bottom on the lid with the hole.
Push the stem through these holes, and screw
the nut (finger tight) onto the stem.
- Gently
place the bucket and lid with the filter ONTO
the top of the second
bucket.
- Fill the upper bucket
with water, and place the second lid on the top
bucket. Gravity will feed the water through the
filter.
- Remember – the filtered
water will still need to be chemically treated
or boiled to kill
viruses.
Last resort filtering
If you have no commercial filtering system, consider a slow sand filter, you will find instructions for that in this 'Water Treatment FAQ' document. A description and construction details are in the 'Slow Sand Filter' section.Emergency Filtering
Why This is Important
Water filtering
removes large contaminants. Eliminating the
smallest microorganisms requires water
purification. These microorganisms can make you
very sick when there may be little or no
medical care available. They are found even in
the most pristine mountain
streams.
How to Purify Water in an
Emergency
Step
1: Preliminary cleaning (for dirty or
cloudy water)
- Let water sit in
containers for a day to allow solid materials
to settle. Siphon water from the center and
middle of the container.
- Put this water through several layers of coffee filters or clean cloth.
Step
2: Treat the water using any of these
methods:
- Water purifiers and
filters. Consider existing in-house water
filters, especially those that come with a
pitcher. Caution: make sure the filter removes
microorganisms, not just chemical taste. Small
personal and family-sized filters are available
in camping supply stores and on the
internet.
- Chemical treatment. The American Red Cross recommends 8 drops of regular unscented bleach (look for ‘sodium hypochlorite’ on the label) to each 2-liter bottle of clear water and 16 drops per gallon. Shake and let stand for 30 minutes. There should be a slight chlorine odor. If not, repeat the treatment.
NOTE: After
putting bleach in the bottle and stirring,
slosh some of the water in the cap and rim of
the bottle or bucket. This will disinfect these
areas.Boil water vigorously
For more
information, see Food and Water in an
Emergency.
- Boiling. Boil water
for 12 minutes at a vigorous boil (NOT a
simmer). This method uses heat energy, which
may be scarce.
Solar water disinfection (SODIS). If you have no bleach, and cannot boil your water, consider solar water disinfection. This requires relatively clear (not muddy) water, a favorable location (Southern US) and good weather conditions.
- Go to Solar Water
Disinfection for requirements and limitations
of this system.
Step 3: Taste
enhancement.
- Before boiling
water, add a pinch of salt.
- For
boiled or chemically-treated water, aerate the
water by pouring it from one container to
another several
times.
