We’ve all seen those old Western movies where the hero is crawling on the desert floor with an empty canteen and a parched throat. None of us want to experience that torture. It’s bad enough watching the bad acting. Same goes for heading to the backcountry for a weeklong wilderness experience. Nobody wants to be caught short of fresh drinking water.
Here’s where the do-it-yourself approach to human-powered outdoor recreation really comes in handy. The stove we built in Part One of this three-part DYI series, can be seen as an inexpensive alternative to a store-bought stove, and as a tool to help us understand how camping stoves work. Because the more we are familiar with the inner workings of equipment, the more likely we’ll be able to solve challenging issues with that stove.
It’s a given. Your gear will fail you.
That being said, the water filter we’re building today falls more into the understanding of how filtration systems work. Again, if we comprehend how our equipment works, we can better take care of that gear and repair it when it reaches a point of failure. And, if you have spent a considerable amount of time traveling in wild places, you know that your gear is eventually going to fail.
First off, there are three tried and true methods of water purification — boil, filter (purify), and chemical treatment. (For more on this, read Stay Sharp in The Offseason By Following the Way of the Farmer, available here on the NCOAE Blog.)
The industry standard when traveling with groups on guided trips in the backcountry is the use of chemical treatment, typically Iodine. That’s because Iodine is inexpensive, easy to carry, and highly reliable. Many outdoors enthusiasts use a commercially available filter, life straw, or gravity feed system. Not surprising, many don’t know how they work or how to repair them in the backcountry. This lack of knowledge has cut short many a trip due to a water filtration failure.
Once, while traveling in Nepal with a group of students from NCOAE, I was
