We will focus today on home and small group needs for water, incorporating knowledge from the prior two segments to complete the picture.  The needs of each home will differ considerably due to varying needs of water consumption.  A two-story home with five children, two parents, and an elderly grandparent with a long-term illness, for example, will need a different amount of water than two brothers in their thirties living in a small cottage.

The basics we'll cover can be tailor-made to fit the situation that governs your needs.  Conservatively speaking, each person needs between 1-2 gallons per day for intake; this does not include use of showers, toilet, sink, and laundry.  As we covered in part 2 of this series on water, during a survival/grid down scenario, there are a number of diseases that must be taken into consideration.
