AN INEXPENSIVE
WATER FILTER
It is entirely possible that
you may have to use surface water for survival. Water from a
stream, river or lake is not clean and must be boiled before use,
but in a survival situation that may be all you have available.
Water is heavy, and if possible it should be collected via gravity
or siphon into some type of portable container which can also
filter out any debris which may be present in the water.

The filter bucket sans top. The nylon
filter is in place inside the bucket and does not touch the bottom
because I used a tall 7 gallon bucket. Note the filter is
tied in place so it will not slide down. The outlet on the
bottom of the bucket is a 3/4" ball valve with a 3/4" pipe nipple
on the end, and a garden hose can be attached to drain the water
when needed.

The top of the bucket fitted with two 3/4" pipe
nipples and a 3/4" 90 degree elbow. A hole is drilled in the
top for one nipple and the unit secured with 3/4" pipe nuts.
The top is then placed on the bucket to make a sealed unit.
A garden hose can be screwed onto the nipple for water intake.

The filter is a fine mesh nylon paint filter
for 5 gallon buckets. It filters very well, can be washed
and cleaned, and if used with care can last for many years.
Before TEOTWAWKI, this filter bucket assembly has marvelous
utility for filtering fruit juices before canning, raw honey
before bottling, etc.

These are the parts needed for the water inlet
for the bucket top...a 90 degree elbow, two 3/4" pipe nipples, and
two 3/4" lock nuts. The hole in the top of the bucket can be
carefully cut out, then filed to fit, or cut with a Forstner wood
bit.

The secret to holding the filter inside
the bucket. Using a 6 foot length of sash cord or
cotton clothesline, a 3" loop is tied on one end and another
loop tied 27" from the loop end. The cord is wrapped
around the bucket, the free end is passed through the loop
end, back through the middle loop, and then the cord can be
pulled tight to cinch in the filter bag.

The intake end of the garden house
feeding the top of the bucket should have a coarse leaf
filter. A gutter downspout leaf filter (far left) can
be clamped to the end of the hose, or a 4-in-1 foot valve
screwed to the hose as a filter. The foot valve has
greater utility, but the downspout filter is much less
expensive.

It may not be possible to find water at a
higher source for gravity flow. An inexpensive 2 cycle
gasoline water pump can pump water up to 40 feet elevation,
and need only be used for a half hour a day if the water is
pumped into a storage tank when then drains by gravity flow
to be used as needed. In the photo at left, I have
stored a 3/4" brass foot valve on the water outlet simply to
keep the impeller area clean, plus the foot valve is always
with the pump.
