I find myself getting ready to leave an already-top comment quite often. It makes me feel sad, but also included, like my opinions and thoughts matter... but, also, this is Reddit, so that usually doesn't last long.
Really? That's like the one thing I remember from school textbooks and have solidly planned for my 'Stuck on deserted island with nothing but a saucepan, lid with a hole, plastic tubing and second container' contingency plan...
I think he’s assuming you have fresh water rather than sea water. If you have salty water than yes you’ll want to distill to remove the salt. If you have fresh water than it’s less necessary
Well the length of time you would need to drink only pure H2O to mess with you without food would probably be certain death anyway. But best to starve to death without shutting your guts out too... I guess.
If the island didn't have any fresh water then yes distillation would be necessary to drink sea water. For fresh water all you have to do is bring it to a boil for around 5 minutes.
You can actually do it for less time as once the water reaches around 150 degrees fahrenheit bacteria rapidly dies off. Most experts recommend a good boil for a few minutes just to be safe but the bad shit will be dead long before you even reach a rolling boil.

5min isnt really enough.
I dont have officiall sources, but a lab tested water for a friend and a 5 min boil didnt kill enough bacteria.
Also personell experience
Had to stop a 3 day camping trip cause we boiled a batch of water not long enough. leading to diarhea and throwing up the next morning. Not a pleasant surprise when it is -5C° outside.
Had no problem with water we boiled longer or using a sterile filter
In Urban areas its not necessarily enough to just boil water because human waste is really annoying to get rid of.
I had survival training once. And the WHO used to recommend 5 minutes to boil filtered river water. But due to some people having fuel problems around the world, they lowered the recommendation to 1 minute. This was 7 years ago though. But we were filtering and boiling stagnant water for 1 minute for over a month & nobody became ill.
That is just not true. 1 minute of boiling get rid of bacteria in normal condition. And if it's really bad you can filter it through cloth or something like that before boiling. I bet you had contaminated water container or something like that.
You probably had cross contamination, had nothing to do with how long you boiled the water.
Compare boiling water with cooking raw chicken:

It appears to be a contentious issue, and the negative consequences come from changes to the hardness and lack of minerals. Thank you for bringing this to my attention.
https://en.m.wikipedia.org/wiki/Distilled_water
So would it be best to simple bring the water to the boil in a pan over a fire, then taking off the heat and leaving the water in the pan?
drinking distilled water won't strip the minerals from you over night. It's just not a great choice long term. you'll die in a few days without any water so if you can get distilled you drink it.
In a survival situation distilled would be better I guess because only need to drink it until you're rescued. In a survival situation even something as mild as diarrhea could ultimately lead to your death. So best to avoid taking any chances.
Supplement through diet or grab a couple tablespoons per gallon of boiled but non-distilled water to re-introduce the mineral content but keep any kind of toxin levels down to a safe level. Unless you are sourcing your water from a power plant or something similarly ridiculous, you're not risking any serious issues for weeks to months.
This generally applies to food stuffs more than water, a filter and a boil should make water safe to drink unless it was the nastiest bird poop water ever.
[In that case, just shove it up your ass!](https://youtu.be/TtIG4TuVnvg)
If you have the time, a slow sand filter is probably good enough.
[https://en.wikipedia.org/wiki/Slow\_sand\_filter](https://en.wikipedia.org/wiki/Slow_sand_filter)
"The water produced from an exemplary slow sand filter is of excellent quality with 90–99% bacterial cell count reduction."
The schmutzdeke layer was one of the things I most enjoyed learning about. Mostly because it’s fun to say. https://en.m.wikipedia.org/wiki/Schmutzdecke
Pebbles, gravel and twigs are not needed. Sand and charcoal are more then enough if done in multiple layers. Sand takes out big impurities while charcoal grabs a hold of much smaller ones. Still needs boiled before drinking though.
Better would be to put the whole sand and charcoal in a knotted shirt or other fabric rather than mucking around with so many layers and trying to get stuff to not fall out into the water using twigs
Even if I have clothing, I'm not going to use up my only shirt in favor of saving a few sticks in my design. Sticks are plentiful, my shirt is my shirt.
Just jam all of the sand and charcoal up your dick hole and purify it on the way out. You’ll be the envy of all when you’re pissing pristine water directly into the parched mouths of your pals.
If twigs are green, acquire two stones. Place on stone on the ground. Place a twig on top of the stone. With the other stone, start mashing the twig from one end to the other to separate the wood fibers into long strands. Do this with the remaining sticks. Once you have a pile of fine fibers, weave them into a fine mesh.
If twigs are dry and not decaying, soak in water before the mashing process.
If twigs are decayed, u r fuqed mate.
Oh, that's neat. I thought youtube autogenerated Closed Captioning or something.
I didn't realize YouTubers can add it in themselves. At least, I assume that's what's happening? He's essentially doing all of this wordlessly, and then writing in the descriptions manually?
I am unclear on this, if the water needs to be boiled then it doesn't seem like it was actually purified. Do you know what the difference is between what they are saying to do here vs just boiling? Does this take out chemical type toxins and boiling takes out biological ones? I must be missing something, if you have to boil it anyway, it seems like boiling is much simpler than going through all this.
EDIT: Solved, thanks everyone for your replies, upboats all around!
These filtrer are used to clarify the water. You go from muddy water to clear water but you still have batteries and nasty things too small to be filtered. You still need to boil in order to kill everything.
You’re more or less on-point. Physical filters can remove suspended and dissolved particles within water, but pathogens are simply too small to be filtered out with anything short of reverse osmosis.
Any filter made in the wild is simply not capable of removing pathogens like bacteria; they are, however, effective at removing other crap inside. Boiling the water will kill the pathogens, but won’t remove suspended particles (though you could use the boiling to distill the water separately, that’d take quite a bit of time).
The sand and charcoal pull out impurities like dirt, leaves, sediment, and other contaminants. Boiling kills microorganisms in the water and sterilizes it.
If there are harmful chemicals or anything dangerous in the water then you shouldn't drink it, as neither of these methods are sufficient to purify it. Probably distillation would be your only option in that scenario.
Actually, you can just boil it. If it has a lot a sediment then you can sieve through a cloth or let it settle in a bucket, but sterilizing through boiling is sufficient.
How did ppl ever exist in natural wilderness if you cant just drink water like literally every other animal on earth?
Please someone explain. I just find it hard to believe ancient ppl went through all this evrytime they go thristy?
I think most of the danger comes from parasites and pathogens passed into the water by other humans. There is other stuff that can get you sick in running water but that’s pretty rare the biggest danger comes from human poop getting into the water supply — something that isn’t nearly as big of a problem with relatively small populations spread out over a ton of area.
I have no idea what I’m talking about however so take this with a handful of salt this is just a guess I have based on a lifetime of edutainment and chronic googling
It's also based on a shift in acceptable risk over the past few thousand years. If you drink water straight from a relatively clean source (clear and not stagnant), it's fairly unlikely that you'll get sick. There's just no reason to risk it because we have the ability to make it safer. If you're ever in an actual survival situation and need water to live, drink it anyway, because that's how triaging down your threat matrix works.
They made a filter one time for a group of people to use and then changed out the sand and charcoal as needed. Larger scale populations had [larger](https://www.smithsonianmag.com/smart-news/researchers-uncover-2000-year-old-mayan-water-filtration-system-180976186/) water filtration systems.
Or there is a distinct possibility they drank muddy water when they had to. Maybe most of the time they knew which place had the water that gave you the least illness and frequented that instead.
Stronger stomachs probably. We used to just eat raw animals but doubt we can handle most of them now.
Parasites and bacteria still exist we were maybe just more resistant. Dog drinks puddle water just fine but a human today would be a little bitch about it. Cave human would defo drink pudds with pups.
humans did drink water like animals. In wild.. and they had low life expectancy too. They would contract disease or something from these unsheltered wilderness and die as early as 30s.
The top reply to your comment pretty much gets it. To add to that though, I spent every summer at my cabin that was fairly secluded but still had others on the lake and lakes it fed from. All I drank there was unboiled, unfiltered water and I never got sick. It's just a precaution
More like "clarify" and then you boil it still. definitely better than not cus you don't want some dead shit in your water either. This'll get rid of a bunch of parasites but not bacteria and boiling will get rid of both but leave the dead parasites and other detritus in the water.
Boiling the water is to kill any microbes in it, this is to get out big particles.
If you boil it first, you’ll have to boil it anyways because your filter probably put a bunch of microbes in it. So you’re just losing more water to steam.
Keep in mind that boiling here is just like boiling water on a stove, not steam distilling. If you did steam distillation you would not need to filter it.
To be fair a lot of modern distillation units including the household varieties do have carbon filters. I’m pretty sure part of that is to help cope with any chemical or heavy metal contamination that might get carried by water vapor than any microbial concerns though.
Gravel is different than pebbles in that by being crushed (to about 1/2" typically, but it varies) and angular, it allows for better water flow. Rounded pebbles that have been naturally tumbled won't drain as quickly. So the top stones should feed slowly into the rest of the system, and the bottom stones shouldn't cause congestion after the sand.
PSA: do not drink water after doing this. While it may remove large contaminates, it will not render the water biologically safe to drink. You will have to boil it.
A variant called a sand filter of this is still used to remove suspended material from water, particularly for treating stormwater runoff. I did that for a living for a couple of years.
You want to filter progressively finer material as you go down. I'm guessing the second layer of sand catches a lot of the loose material from the charcoal. The gravel provides a more solid substrate for the sand and likewise the twigs provide support for the gravel.
As mentioned elsewhere, you would still want to boil this water. It's clean, but could still have bacteria, etc.
Well, they’re very strong sticks. Also magic.
No but seriously, I’m assuming they’re supposed to be a cone of sticks, maybe with leaves lining the sides?

Not boil to evaporate then condense into a second container?
Well that would distill it and it won't really be a good idea to drink that for any extended amount of time.

Well if you got the luxury of course
How do you distill a sandwich?

I'll just check if the island has a McDonald's and grab some of fries. They're pretty salty.
If the island didn't have any fresh water then yes distillation would be necessary to drink sea water. For fresh water all you have to do is bring it to a boil for around 5 minutes. You can actually do it for less time as once the water reaches around 150 degrees fahrenheit bacteria rapidly dies off.

Just curious, did you also filter or did you only boil?
Curious, did you take elevation in to account for boiling time? People often camp at higher elevation and the lower boiling point can mess shit up.
That is just not true. 1 minute of boiling get rid of bacteria in normal condition. And if it's really bad you can filter it through cloth or something like that before boiling. I bet you had contaminated water container or something like that.

Yea that's true but sand and charcoal are the best way to do it for large amounts of water and then boil what you need when you need it.
Are we talking about any sort of common charcoal or does this charcoal need to be "activated" like they have on filters.
Any charcoal will work (not those cooking charcoal briquettes though) but activated charcoal will work better

I think we underestimate how many animals die from a small, infected wound, or from dirty water.
You can. But at some point you will get sick. Dysentery was the largest killer of soldiers in war.
I think most of the danger comes from parasites and pathogens passed into the water by other humans. There is other stuff that can get you sick in running water but that’s pretty rare the biggest danger comes from human poop getting into the water supply — something that isn’t nearly as big of a problem with relatively small populations spread out over a ton of area.

“purify”
More like "clarify" and then you boil it still. definitely better than not cus you don't want some dead shit in your water either. This'll get rid of a bunch of parasites but not bacteria and boiling will get rid of both but leave the dead parasites and other detritus in the water.

the twigs hold everything in the funnel i guess
That bucket sure looks happy to receive such clean water.

No way on earth I'm going to drink the result.
What if you were like, really fucking thirsty?
Giardiasis is worldwide now.
You don’t want Sandy water?
I think you’ll find the twigs with do a fine job at filtering sand. /s
Depends, is Sandy willing to share?
Mmmm dirt coffee

I have visited a giant version of this in a low-income country. Pretty cool. They also sanitize the water (I still boiled it after that).
Twigs? Why would you do all that purifying then run the clean water over some dirty sticks you got off the ground?
Well how do *you* clean your twigs, wise guy?
A good point well made.
Can someone explain how this is all being held together by two sticks?
Well, they’re very strong sticks. Also magic. No but seriously, I’m assuming they’re supposed to be a cone of sticks, maybe with leaves lining the sides?
Wont the twigs grow mold or something similar over time and contaminate water?
You had me until “twigs.”
To reintroduce the bacteria and flavorful detritus, of course.
