Iodine tablets are the traditional choice and most of our group decided to remain loyal to their use. After filling your bottle, while carefully avoiding floating chunks of debris or bugs, it is necessary to wait 30 minutes before you drink it. The sterilization practice includes forcibly squeezing some treated water out through the loosened cap to ensure bacteria-free contact while drinking from the container. We boiled water for cooking purposes on several occasions. I wanted to give the pump purification system a try. Our first morning found me standing in the cool lake waters wishing I had two extra hands. The instructions emphatically admonish that the bottle-filling tube must remain uncontaminated and housed in a separate plastic zip-lock bag between uses. The pick-up tube comes with an attached foot valve sediment filter and weight to keep it submerged below the surface.
It was a bit cumbersome to adjust to, but once you’ve gotten the hang of the process, it goes rather quickly. The ceramic cartridge filters down to 0.2 microns, removing all known disease-causing bacteria and protozoa from your drinking water while the compressed activated-carbon filter removes chemicals and pesticides from the water, improving taste and odor of the water you’re pumping. A side benefit was the removal of tannins, which resulted in crystal clear water. A small bottle of chlorine comes with the kit and a few drops are added as a precaution along with a 10-minute contact time before drinking.
When I came home and flushed a 3.5-gpf water closet, it struck me that I had just used more potable water than our entire group used in a single day’s time. Doesn’t it seem ludicrous that we utilize potable (instead of gray) water for flushing water closets in this era of diminishing resources? Dave Yates owns F.W.

So there I was, thigh-deep in water, one hand holding the intended receiver with clean hose, the other hand holding the pump assembly and needing a third hand for operating the lever. With the bottle now firmly tucked under my arm, the opposing-action pump lever gave me enough oomph to pump water faster than the filters could accommodate and the unit’s relief valve opened, squirting me in the shorts!
I was impressed by the small amount of potable water we really needed for daily survival. Basic needs included cooking, drinking and personal hygiene. An inch of water in a cup sufficed for brushing teeth, a quart for drinking (additional hydration is gained from moisture in foods) and about a gallon for cooking the freeze-dried foods we packed.
