One of the biggest issues for many people if SHTF is going to be finding and maintaining a consistent, safe water supply. As the water boils, it will turn to steam, which will rise to the lid and run down the lid into the cup, leaving salt and other impurities in the bottom of the pan. Hint: You can perform this method for turning salt water into drinking water using solar heat, too. This method for turning salt water into drinking water allows you to distill a bit more water though you’ll still be using quite a bit of energy. Place the tube through the cork or seal so that it is even with the bottom of the cork, then put the cork in the top of the bottle.
Run the tubing to another container that is lower than the bottle so that the water can run out of it and not back into the bottle.
Bring the water to a boil and watch as the steam comes out of the water, through the tubing and converts back to water as it drips out of the end of the tube into your container.
This method is sort of a morphing of the two processes we’ve already discussed and may come in handy if you’re on the run and don’t have access to anything other than your camp pan. Form a cone with your aluminum foil so that the tubing is wrapped around the top of the cone and the bottom is used to seal the pot. As the water comes to a simmer, it will start to evaporate and the steam will come up through the tube, dripping fresh water out the other end. If you have the cash, you can invest in a solar-powered desalination unit that turns salt water into drinking water so you’ll be ready when SHTF. You can also use reverse osmosis to desalinate water but it’s not exactly something that you can build. Along with desalinating water, all of the methods that we’ve described today also distill the water, effectively removing bacteria, viruses and other impurities from the water.
If you have any other great ideas about how to turn salt water into drinking water, we’d love to hear about them in the comments section below!
About the Author Latest PostsAbout Theresa CrouseTheresa Crouse is a full-time writer currently living in central Florida. This method is als good for pollutes, non salt ater also (and it is better than just boiling). This general concept could be adapted to use a large, inverted steel salad bowl so long as some spacers are used to create a gap between pan and bowl.
Be aware that distilled water is hypotonic, and drinking distilled water over long periods will leach minerals out of your body and cause diseases related to mineral deficiency.
There is a older book called "the solar boat book" has some more alternatives for converting salt water to drinking water. The sun will evaporate moisture from the dirt in the hole which will drip down the cone and into the cup. I have tried this method at our beach house, and technically, it works, although the output of distilled water is very low. I used a clear sheet of heavy plastic (a wrapper from a bed mattress), and used it to cover a hole that was about 5' in diameter, and about 2' deep. I've tried all waters, but have never felt any real benefits until I began drinking distilled water consistently.
I suppose scientists will debate you regarding hypertonic water, including the author of this article, cited by the World Health Organization regarding the dangers of drinking demineralized water. I have no issues with drinking distilled or RO water in an emergency scenario, but I don't think it's advisable for the 'hypertonic' reason. Being hyper-, hypo-, or isotonic doesn't give us any real indication of what it will do inside the body, and particularly at the cellular level.
So, Jason, please explain, without another long diatribe devoid of actual, direct argument, how, by drinking the world's best natural solvent, distilled water, that every drop you drink will not leach minerals from your body? I typically use a tarp and twine attached to 3-4 trees with an object of weight in the center to create a cone. For the longest time, it was believed that this class of molecules could not exist without water, since the chemical was believed to be essential for many of the processes proteins need to complete in order to function properly.
While a lot of studies still remain to be done on the issue, the fact remains that the presence of liquid water on an exoplanet's surface was considered to be a make-it-or-break-it factor in determining whether that world has the potential to support the development of life as we know it.
UB scientists focused on the role that water plays in the survival and function of these large organic molecules.
Since the dawn of evolution, proteins have always existed in water-rich environments, including those found in living things. In the recent study, scientists have been able to demonstrate that myoglobin, an oxygen-carrying protein similar to hemoglobin, is capable of refolding in an environment nearly devoid of water molecules. Stop to think about it though, because there are situations where your access to fresh clean drinking water could diminish or disappear.
To make a stock of chlorine solution (do not drink this!) dissolve 1 heaping teaspoon (about one-quarter of an ounce) of high-test (78%) granular calcium hypochlorite for each two gallons (eight liters) of water.


I read a comment on another blog from a guy whose well pump died and he thought he could get water out of his water heater.
Lesson learned: regular maintenance and draining of sediments out of your water heater is a must if you want to count that water as usable without tearing apart your water heater. You could use a siphon to get the water out of either the hot or cold connections to the heater.
I have looked into buying a cart or tricycle, but those are expensive and some reviews (Amazon, etc.) say they are flimsy. Add Tang, instant tea, instant coffee, fruit mixes to camouflage the filtered taste if any. I have a canvas bag that holds 2 teaspoons, (2) 2 liter bottles, 2 gallon jugs, and my CH bags still in the packages bought in.
Oh, yes, your pool shock is what I have, and it IS calcium hypochlorite–I misread the post. Yep–your old trustworthy pool shock is what will clean and purify your water for you.
The bleach has a 5 month shelf life and requires lots of space; the pool shock has an indefinite shelf life if kept in the paper bag in a cool, dry place (and mine is)and takes little space. As far as purifying water, boiling is a viable short term solution, but very energy & labor intensive long term.
I used Google Earth to locate natural water sources near my current home, and I was pretty surprised to have found as many as I did including pools at nearby residences.
A few years back I realized just how bad things can get super quick without clean water, and to this day and ever after I save every plastic bottle I get for water storage purposes. People take water and clean water totally for granted and that is easily one the very worst of mistakes there are. Environmental expert Robert Jackson explained to NPR that even though the filter removes the majority of the bacteria, it should still only be used in survival situations when there are no other options. You can read more about the study in the team’s paper on PLOS ONE and thewriteup on MIT News.
I wouldn’t use this trick to filter urine or anything, even if there is no water around. Tagged  disaster, DIY, Do It Yourself, emergency, family, Preparedness, Survival, water purification, Wood Water Filter.
HISTORY CHANNEL is searching for ONE family living off-the-grid to star in their own TV series! The problem here is that it requires a ridiculous amount of energy in the form of heat to get the job done. Make sure that your cup is underneath the lowest point of the lid and that the lid seals well.
You don’t want it to boil so hard that it splashes salt water into the glass or upsets the glass. We always include aluminum foil in the list of things to keep in your bug-out bag and this is yet another use for it.
You can buy personal RO devices for your home and even for water bottles but building your own in a SHTF situation isn’t realistic for most people. If you’re using any of the solar methods, be sure to filter the water before you try to desalinate it because the process works best when the water is clear. She was born and raised in the hills of West Virginia, where she learned to farm, hunt, fish, and live off the land from an early age. They're in the early stages of the process and are having a tough time scaling it up in a way that would be efficient enough to make it viable but the research is definitely there. I saw a similar one using a tarp tied between 4 trees with the rock in the middle and a cup under the cone to catch dew as it evaporates.
Our only source of minerals should be foods, particularly plant foods, which is why juicing veggies can be a life saver at times of acute illness. Small ones produce anywhere from 1 gallon every few hours, while larger ones can produce 8 - 12 gallons daily. People (like me) who have switched to or have used distilled water long-term would never go back to any other water. Proteins are involved in converting food into energy, in transporting oxygen to cells via the bloodstream, in defending our bodies against invaders, and many other processes.
Our bodies, for example, are made up of more than 70 percent water, Astrobiology Magazine reports.
Some water filters are good enough to remove much, most, or even all pathogens, which may eliminate the need to further purify the water for drinking. Turns out the water heater had such a buildup of sediment that no water would come out the drain tap.
I bought a cart on Amazon, but before I did that, my plan was to confiscate a grocery cart.


I bought my water heater used (didn’t have enough money for new) and it already has one of those valves on it (the kind with a lever handle).
Not for pilfering, but for barter (or if they’ve abandoned their residence in SHTF time).
Google Earth is so valuable… I used it to scout out my next living locations, my bug out locations, and a whole lot more. Try going two days without any water at all and you will see just how miserable and dysfunctional you and everything else gets, and then, try getting it without a sink or store or whatever modern convenience, and you will definitely see and feel just how valuable it is. Researchers at MIT have found that you can turn dirty water into drinking water with nothing more than a stick.Mechanical engineer Rohit Karnik figured out that the xylem tissue in plants, which is responsible for filtering out air bubbles, can also remove harmful bacteria from water. After making the filter, he poured water containing tiny particles and bacteria through the tube. Even though the pores in the xylem tissue are the right size for removing bacteria, viruses are usually much smaller and most probably wouldn’t be trapped in the filter.
For example, people who live in coastal regions are surrounded by water but it does them no good because one of the quickest ways to die of dehydration is to drink salt water.
Still, it’s effective and if you combine the process with others, such as cooking or heating, you won’t be wasting nearly so much fuel.
You’ll need a metal cup heavy enough not to float or heat-resistant glass, a pot with a domed lid and heat.
You’ll also need a heat-resistant glass or metal bottle, a cork or rubber seal for the bottle, a few of feet of tubing and a catch-basin. It’s just basically a larger version of the bowl-and-plastic desalination method that we just described. It involves using an electrical charge to remove the salt ions from the water and though it’s a great idea, they’ve only been able to reach about 25% desalinization. She prefers to live off the grid as much as possible and does her best to follow the “leave nothing behind but footprints” philosophy. Place saran wrap or other transparent , non permeable material over the hole with the edge weighted in place by the dirt you excavated so there is slack.
Distilled water removes these deposits quite effectively, and improvement continues the longer one consumes the water. It's not only acidic, but also contains pollutants like radioactive elements (eg, strontium), smog, bacteria, pesticides, and so on. Fluoride will already be effectively removed by distillation (note that RO systems do not remove all the fluoride).
Kentucky Conservation Officer Major Shane Carrier and boating education expert Zachery Campbell join us to discuss the thrills and chills of off-season boating and how to best save yourself.
A very small number of people have been known to survive for up to a week without water under special circumstances, but this has been a rare exception. It is often overlooked because most of us have such ready access to it nearly everywhere we go. I use it to drain out the sediments every couple months because I’m on well water that has a lot of calcium in it, which turns to a rock hard crust if you leave it.
Even though a lot of deep aquifers are mapped & a good source, pre-municipal Americans did dig shallow wells.
Obviously activated charcoal is best, but even ground briquettes contain carbon which is what absorbs the impurities.
He peeled the bark off of a short piece of pine branch and attached the sapwood to a plastic tube to make the filter. As of right now, it may not be a large-scale solution, but it could make a huge difference to rural communities without access to manmade filters. There are many methods for doing this but the most efficient and realistic way to do it at home in a survival situation is by using the distillation by evaporation method. You could even substitute plastic wrap for the lid and just put a small rock or something in the center over the glass to form a drip point.
For fun, she enjoys shooting, kayaking, tinkering on her car and motorcycle, and just about anything else that involves water, going fast, or the outdoors. As far as untreated natural water, the best would probably be morning dew far from large cities.
If you use a round, see-through glass bottle or jug, the process will be much quicker because the glass will act as a prism, heating the water faster.
