For most of the developed world, safe drinking water is something we take for granted. We turn on the faucet and nice clean water comes out. We have fresh water to brush out teeth, to take a shower, to wash our hair,,, and our other everyday needs.
Then along comes SHTF / TEOTWAWKI, and guess what, no more nice clean water.
Over the years I have read a lot of articles taking about the most important survival gear items. the list usually ranges from antibiotics to water filters. To me, and my personal opinion, the most important thing during a survival situation is safe drinking water.
Without safe drinking water, life as we know it can not exist.
Lets talk about 3, 4 or even 5 days after the city water gets turned off, people will be drinking out of rivers, creeks, ditches, streams, ponds, lakes,,,,, anywhere they can find water.
Most the most part, people will try to purify the water by boiling it, or using a water filter, or running the water through a shirt or cloth to remove the heavy particles,,,. I guess a major problem lies in urban dwellers who have limited access to fuel for fires to boil water.
