Survival Preparedness Guide – Water
Humans can live for days or even weeks without food but no one survives past 4 or 5 days without water. Living on very short rations, an “average” person can survive on one gallon of water, for replacement of normal activity loss, per day. At that drastically minimal rate a family of four will require 120 gallons of potable water to survive for 30 days.
“…Drinking, sanitation and hygiene constitute the basic human survival needs for water. These needs total about 50 liters (13.2 gallons) per person per day…” (1)
Including drinking, sanitation and hygiene that same family of four would require 1500+ gallons of potable water to survive for 30 days. Storing 120 individual gallons of water to meet subsistence-level needs is easily done, if that’s how you visualize your family surviving.
Storing 1500+ gallons, while making your family’s survival experience more pleasant, is problematic if you do not have the ability to replenish your water supply while off the National Electric Power Grid.
In most parts of continental USA, with the exception of the Southwest, rainfall is fairly regular, reliable and predictably sufficient to be the primary source for your family’s survival water self sufficiency. You will have to make a judgment call and decide how much storage capacity you will need to bridge dry spells.
The water stored in your tanks, or collected from any available source may appear clear, but is not safe to drink. Whether it’s rain, which fell on your roof, or water collected from any available source, it is contaminated with bird feces, insect detritus, decayed organic matter, chemicals and other pollutants. To make any water safe to drink it must first be treated or purified.
Treatment involves adding proportionately large amounts of Sodium Hypochlorite, (laundry bleach), (2)or chlorine iodine. This method should be reserved for emergency or occasional use only, because using these chemicals for long periods of time can be detrimental to your health. (3)
The best way to purify your available water, without treating it with harmful and foul tasting chemicals, is to process it through either; the SURVIVAL H2O Purifier™ or a Berkey®Gravity Feed Water Purifier, both of which make long term water self sufficiency an affordable reality.
