Actually that takes about day. The sunlight needs to be strong and you must have the right kind of bottle (see this article on SODIS)Quote:

mitch.chesney is right, if your in an area where there is heavy vine growth from trees these can be cut and the water (liquid) drank also. I wouldn't recomend bleach ever, and for some reason boiling my urine just doesn't apeal to me either and I was taught to never drink your urine in the Army, but terrain plays a huge part, some plants have liquids in them that are not water but will suffice.
If you're dying of thirst and come across some water that you're not sure is safe to drink? Well, it's entirely up to you and depends on how desperate you are for water. But if you've been wandering around for days without any water and you're starting to feel weak, delirious, and downright desperate for something to drink. You got a choice, you can either die from dehydration or risk dying from unsafe/contaminated water. Now personally, if I was wondering around for days without any water and suddenly came across some, provided it wasn't discolored or have a strange odor… I'd drink it. Why? I'd rather risk drinking unsafe water and hope it would give me enough strength to travel/continue on just little bit further and longer than to give up and die right there on the spot from dehydration. After all, whether you feel ill after drinking some suspected contaminated water or not, if it gives you the strength to place one-foot-in-front-of-the-other and move on, your chances of surviving and being rescued before it actually overcomes you with severe illness is greater then giving up and lying down somewhere and dying, don't ya think? Sure it is! No doubt you probably prefer to have some clean, safe, purified, water to drink, right? Sure, everybody would, but sometimes it's just not possible to find, ya know? And although there are many ways in how to find, improvise and acquire water, the following are the most "commonly overlooked" techniques that require none or very little filtering and "no purifying." And the only things you need are some "clear" plastic trash bags, an empty bottle, and a couple of handkerchiefs, and the more you have - the more water you'll be able to produce. Note: Always pack a few of these in your survival kit, except a bottle, of course. Because a tree holds an enormous amount of water, if you place a clear plastic bag over a "leafy green" branch you'll force it to cough up some of the water through condensation. But it's important to make sure the bag is tightly sealed around the branch or it won't produce any water at all. And no matter where you go today, plastic and glass bottles can be found littered almost everywhere, even in some of the most remote and isolated places of the world. Really! (Well maybe not everywhere…) And if you take a "green leafy" branch and place it inside a bottle and seal it close, by the end of a hot sunny day it'll produce as much as 1/3 cup of water. And so the more bottles and or plastic bags you use - the more water you can produce. Figure it out, bubba! And of course, the best time to acquire clean water is when it rains, and the fastest and easiest way to gather it is by laying out sheets of plastic cut from trash bags. But if you don't have anything to carry the water in, then it's probably better to just roll up the sides of a trash bag and allow mother nature to slowly fill it. And lastly, in the early mornings and some- times late at night, if you tie a couple of handkerchiefs or rags around your ankles and or to the end of a stick and walk through some tall grass you'll be able to soak up quite a bit of moisture, then all you gotta do is wring it out. Yep, a crude, slow method… but works!
When it comes to filtering and purifying water for consumption, you can't screw around and take shortcuts. You either do it right or you're gonna get terribly ill, or worse yet, die from improperly treated water if you can't get to a medical facility in time. Filtering is the removal all "visual" particles and matter from the water such as dirt, leaves, critters, etc, so it can be properly purified and then safely consumed. Purifying is the removal of all "invisible" bacteria, germs and other harmful elements from the water so it can be safely consumed. You got it? In other words, "before you can consume untreated water, you've got to purify it, and before you can purify it, you've got to first filter it." (Untreated Water + Filter + Purify = Safe To Drink)
Film Container Water Filter and yep, as you can guess by the name, it's made out of a 35mm plastic film container, which you'll also need 2 x plastic water bottle caps and either some disposable coffee filters, cotton, or a piece of white cloth. Now I'll bet you're wondering, "What's the second bottle cap for?" Right? Well it's for squeezing out the last few drops of water left inside the filter and for covering the hole (after you have remove the other bottle cap) from the bottom of the film container so you can keep it clean whenever you're not using it. When should you replace the coffee filters, cotton or white cloth? When (a) the filter becomes blocked, (b) the filtered water is dripping very, very slowly, (c) the filtered water doesn't look very clear.
Ther ya go.
Beo,
If you have been stranded with a busted down car or other vehicle/aircraft with a liquid radiator, you'll have a couple gallons of clean water in there. That water's been boiled multiple times by running thru a hot engine. Be careful that antifreeze wasn't added though.
Radiator water? Even without antifreeze, you've got all the rust and crap from your car's system floating gently down to the bottom and if you've got even a trace of antifreeze, well....you were dying anyway, right?
You dont have to boil it that long :o , Remember when it gets to 100oC Everything is already dead you only should leave it for a few seconds after that, Milk is pasturised at about 77oC, If you boil it for 20 mins half of it will be gone up into steamQuote:

4 drops (per quart) of "CLEAR" water. 8-10 drops in "CLOUDY WATER." Let it stand for about an hour. . . .Good to go! ;)
If it is stagnate water I wouldn't drink it. If I had too (in a dyer emergency,) I would boil it, strain it, and boil it again before I ever let it touch my lips!
I carry a NSA filter in my pack. I have filter straws in the BOB's. I know that straining and then boiling works. House hold bleach does work and 2 drops in my army canteen (wait 30 minutes or more)will not kill me but will get the nastys.
Condensation works. You just need a big enough piece of plastic.
Getting water in some areas is not a problem. In some areas, like this desert I live in, it would be intresting but it is do-able.
Beowulf65 makes a good point about drinks unknown water or dieing of dehydration.

I ran across this article on water filtration. I thought it was pretty well written:
http://www.princeton.edu/~oa/manual/water.shtml
I don't carry fancy any things any more, take up to much space
One of the things I do when water is a questionable is to dig a small hole a distance away from the main water source (this makes it less likely to have feces in the water I'm extracting
I've only done this once; normally I carry a couple small water bottles (converted pop bottles) and fill up when I run across good water
If your pretty sure there are little nasties in the water and you are getting to the point of no return
Weigh your options, most get help before two weeks are up in the lower 48 (unless they don't really want it)
It takes about 3-14 days for these pathogens to take effect, so if it was me, I would deal with the doctors when I get out of a situation
The better option is to be very careful, if around a larger water source, walk the edges and find secondary water sources, follow them upstream until you get to areas where it is coming out of the ground or is on a slope that there's no possibility of slow moving water
Another note to consider, there’s a reason they call it beaver fever... :)
You don't even boil it? I doubt there is any place on earth that doesn't have some pathogen in the water today. Even ground water (springs, artesian wells) needs to be purified through some process. Obviously, not every ground water source is contaminated but enough are to warrant treating the water.
We have a free flowing artesian well near our home that has a constant stream of people filling up jugs. The county checks it every week and posts it when they detect some problem with the water.
It's not just about feeling sick. Diarrhea can be life threatening because of the dehydration it can cause. I know you know that but some of the newbys might not.
Seriously, you don't treat the water?
I don't normally (cept when I'm making coffee or soup)
I think one of the reasons people get so sick whan these pathogens are present is they have lost their immunities to these little critters
My stools do soften to a point on occassion (find it more so when fishing beaver ponds and chew the line to break it when changing out hooks instead of cutting it)
Another thing, most of you guys live in flatter country, more fury critters filling all the streams and the potential is far greater than me or a few others living in the Rockies or cascades...
I have drank only the water from my creek every day for 8 years, and never treated it in any way, and never experienced any problem.
In 38 years of wandering, and guiding in Alaska I have never treated any water I drank. However I would not drink out of a city (like Anchorage) creek, at least not after it entered the city.
about the filter it works by turning big pieces of wood into charcoal and then moving the water though it i have tried it works but tastes awfully like overcooked bbq:mad:Quote:

This is the one I carry.
Depends where you're at. Locally, we only have to worry about giardia (beaver fever). A cheap filter (about $30) is sufficient. They used to have them in the Campmor catalog, but I don't see them in the latest issue. I often just take water from springs instead.
Rivers are generally not as good a place to get water locally as that is where you find the most beaver. Taking water from the center of a large lake is usually the best if you don't plan to use a filter. Purifiers, such as the Pur or Katadyn products, are usually overkill locally.
Giardia is from Europe. There was a time when you could drink the local water without any problem. Giardia was never a problem locally, until 1973 when (apparently) someone came over from Europe and took a dump. Nasty bugger!
I cook for a living these days, and I know a little about sanitizing things.
If you're using bleach, two or three drops in a quart of clear water will kill stuff.
I use the kodine from my first-aid kit. It fixes the water like the pills, and I can treat cuts and scrapes.
I think boiling would be the best way if you were in a survival situation. All that requires is a fire and some sort of metal container (soup can, bowl, soda can, etc). Plus as long as you have these and a sufficient supply of wood, you will never run out.
Just make sure the liquid is clear, colorless and odorless. Dont drink liquid that is milky, yellowish or pinkish. Dont place the vine in your mouth. Acids like oxalic may be present in the cambium which will irritate soft skin. let a few drops fall into your palm and taste it first with the tip of your tounge. It should not cause any feeling of irritation, burning etc.Quote:
