JUMPSTART: Water2 – Needs

July 2, 2013

in Jumpstart, Water

JUMPSTART is a survival methodology that includes consideration of others around us who are either not aware of the need to prepare for emergencies or have made a decision to lower the priority of that need.
For an introduction see: JUMPSTART: Overview

This is the second part of a series of five articles on Water.

Needs over time

Most adults need somewhere in the area of 1 gallon per day of water for drinking alone and that number increases with heat or activity. When water is available, we need about another ½ gallon per person per day for other uses, such as washing, cleaning or flushing. We need to have an ability to capture or collect new water, either from some source like a spring, a creek, a river or a lake, or from rainfall. We need to have the ability to store enough water to last until the next collection opportunity. (very important with rainfall collection) We need to know how to filter and purify our drinking water. We need to understand and be able to follow a strict water discipline methodology to avoid any waste.

For 2 adults, each using 1 gallon per day for drinking and ½ gallon per day for other uses, we need 3 gallons per day. Over time, we will need:

  • 15 days = 45 gals
  • 30 days = 90 gals
  • 60 days = 180 gals
  • *90 days = 270 gals (no rain threshold)
  • 180 days = 540 gals
  • indefinite = collection, storage, purification

90 days is identified as a key “tipping point” because in this area, it has never gone without raining for more than 90 days consecutively. On the other hand, often the rainfall in this part of the country is measured in fractions of inches. This tipping point will vary with different climatic conditions, times of year and collection and storage ability, but it is important to identify it. The same general principles apply to other water sources.

If we accept the 90 day tipping point, then we will need to have the ability to store at least 270 gallons of water in reserve for 2 adults. This is important knowledge.
