Another follow-up to Open Thread: The Little Things That Makes A Difference
There isn't anything more important to your prep than water but it also is one of the most neglected and difficult things to prep. This is primarily because we take for granted that water will come out of the tap because for most of us, it always has. If you live in town the water is probably treated and comes from some municipal authority. If you live in the country, it gets pumped from ground water. Either way it requires electricity at some stage. You can go for a long time without food but without water you are screwed in a matter of days, even more so if it is really hot.
So what is your long-term plan for when the world ends as we are expecting it to and the power goes out, not for a few hours but for good? Dying of dehydration is an ugly way to go and so is dying by shitting your guts out from drinking unfiltered water.
Eaton Rapids Joe left a couple of comments on the open thread about "slow sand filtration" and then did a post of his own that is easier to read, Slow sand filtration. Read it and learn it, do what I did and convert it into a .pdf file and save it. If you are lazy/smart you can download the pdf I created here. This is important info for you to check out. Where else are you going to read about Schmutzdecke?
Having ready and reliable access to safe drinking water is going to keep you alive more than having the latest optics on your AR. Don't neglect the most critical stuff or you won't live long enough to regret it.
