A collection of survival tips which could help you survive anywhere on earth
Posts Tagged ‘Water’
Some plants have leaves which are cup-like in shape; such that they will collect pools of water in their leaves.
Plants which grow leaves directly from the trunk, like most palm varieties, some ferns and bromelaides (from the pineapple family, these are usually small plants which grow on the side of other, larger, trees), often have leaves which are designed to catch rain and channel it down to the base of the leaf, where it meets the trunk. The water pools there so that the tree can slowly absorb it. These kind of trees and plants are often, but definitely not always, found in tropical areas and can provide a useful source of water. One great example of this is the Traveler’s Tree (Ravenala Madagascariensis). This comes from the banana family and can hold up to 1–2 liters (2–4pt) of water which pools between the leaf stalks where they attach to the tree.
Banana plants hold a descent amount of water in their trunk. This can be accessed by either slicing off the trunk at about 30cm (1ft) from the ground or by inserting a tap into the trunk. To tap a banana plant, take a 20cm (8in) length of bamboo, about the diameter if your thumb, ensuring that it is hollow all the way through. Sharpen one end with your knife and insert the bamboo tap firmly into the banana plant at about a 70 deg angle to the trunk of the plant. This will allow the water to start running out of the trunk and down through the tap. Create a water trap underneath the end of the tap, by placing a large leaf or piece of plastic over a depression in the ground, for the water to drip into and leave it for a few hours before returning to have a drink. The water may taste like green bananas but it is drinkable.
Other water bearing trees are the Boabab tree (often known as the tree of life), found in Australia, Africa and Madagascar hold a very large amount of water in its trunk. This tree also provides shade and edible fruits.
Extracting Water from Tree Roots
It is possible to get water from the roots of some trees by removing the bark, cutting shavings into a pile and pulping the root shavings with rocks then squeezing the water out of the pulp and letting the water drip into your mouth.
The roots of some trees will yield more water than others. Some trees with a higher water content are: the blood wood, the water tree and the desert oak; all found in Australia.
This method works if you are desperate but uses a lot of energy for the yield.
Water from Bamboo
Bamboo will usually yield an excellent supply of water in the hollow stems, between the joints. Water can be located by tapping the stem about 7-10 cm (3-4 inches) above a joint. If you hear a dull sound then they will most likely have water inside. You can shake the stems and listen for water inside too. Aim for thick stem bamboo. Water is most likely to collect in older, yellower stems. When you locate water, cut a notch just above the bottom joint and the water will run out freely. This water will be clean and good to drink as-is.
Water from Vines
Some vines can yield a reasonable supply of drinking water. The general characteristics of such vines are rough bark and off-shoots of about 4-6cm (1-2in) thickness.
Always be weary of plants with a sticky, milky sap as this is usually poisonous. Vines are no exception so observe this when trying various vines for water.
To get water from a water-bearing vine, simply cut a deep notch in the vine, as high up as you can, (it is important to cut the top first or else the vine will act as a vacuum and suck the water back up the vine) then cut it completely through at the base. At this point the water should begin to run out. Check that it is not sticky & milky and then collect the water in a container or let it run/drip straight into your mouth. Do not put the vine in your mouth as some vines can irritate your lips.
When the water has stopped flowing, cut a section off the bottom end to release water still inside the main vine. Repeat this until all water has been released.
Water from Cacti
Whilst most cacti have a fluid content, not all cacti yield fluid which is safe to drink. Some cacti can be very poisonous; like the the giant Saquarro cactus found in the California and Arizona regions of North America and in Mexico. On the other hand, the Barrel cactus is an exception to the “Avoid milky sap ” rule. This life saver can yield around a liter (2 pints or 33oz) of drinkable sticky milky sap. The best way to handle cacti is to cut off a piece to expose the inner flesh, then either cut chunks out pf the center to mash or suck the moisture out, or to cut and mash the flesh, while still in the base, till there is enough liquid to collect or drink then repeat.
Always be very careful when handling cacti as you really don’t want to get the spines stuck in your skin as they can be almost impossible (especially the fine ones) to get out in a survival situation and if left, they can cause weeping sores which can quickly turn septic.
Cactus fruits such as prickly pears can also provide liquid.
The liquid in some cacti can be tasteless and sour in other varieties.
Filtration should not be confused with sterilization. Whilst filtration will clear the water of debris, make it clearer and often make it taste and smell better, it will not remove bacteria so unless you are highly confident that the water is fresh, it always pays to sterilize it with water sterilization tablets, or by boiling or distilling it.
Fortunately there are many ways of filtering out the yucky bits with things which are readily available in the wild. The basic idea is to remove debris of all sizes by passing the water through different sized filters. Sand, Dried Grass, Pebbles and Charcoal all make excellent filtration material. Combine some of these in layers (smallest to largest) in a sock or your pants leg/shirt sleeve tied at the end and you’ll be good to go. Pass the water through the layers of filter material, catching the clean water as it comes out the bottom. It often pays, to run a couple of cups through the filter just to remove any fine dust or charcoal powder which may initially come through.
The type of filter that you will make will depend on the resources you have available at the time and how you intend to use the filter. There are several variations of the basic filter as mentioned above and then there are also some man made solutions which you may be fortunate enough to have with you. The following techniques listed are just some ideas but with a little ingenuity and resourcefulness, your options are almost limitless.
A great method for filtering water from a pool if you don’t have the means to boil it is by digging a hole beside a pool of water (1ft/ 30-40cm away and deeper than the water level in the pool) and creating a well.
Let this sit for a while and the water will filter through the dirt and sand, filling the well.
This water will initially be murky so scoop that water out and let it fill up again. This time the water will be clearer and good to drink.
Charcoal Straw Filter
Sometimes the only water available is in a crack or pool which is too shallow to fill a cup. This is when a filter straw comes in handy.
You must find something long and hollow like a straw. This maybe a piece of frame from a backpack or a length of hollow stalk from a dried plant or Reid. Stuff this with a wad of dried grass and push it down with a stick. place crushed charcoal in the straw next followed by sand. Finally place another wad of dried grass in the end and pack it down (not too firm but firm enough to hold the filtration material in place). You should now be able to drink the water directly through the straw.
Commercial Water Filter Straws
These nifty little devices can be purchased from most camping and fishing stores and are a nice edition to your survival pouch. Use them to drink right from the water source. They will filter the water and also kill about 95% of any bacteria. They can be used for about a week before they need to be discarded.
Cutting a section of thick bamboo so that it is hollow at both ends then packing one end with a wad of grass and then filling it to 3/4 with sand will make an excellent filter.
Water Sterilization Tablets
These can be purchases from most camping and fishing stores and are a handy addition to your survival tin. The manufacturers instructions on the packet should be followed.
UV Water Sterilization Pen
The handy devices are relatively new on the market, and are a really handy piece of kit to carry on your adventures. Retailing at around $260USD, they work by you shining the UV light into the water. UV light scrambles the DNA of nasty disease-causing bacteria, viruses and parasitic protozoa causing it to become inactive. At a relative lightweight 110g (3.8oz) incl. batteries they will disinfect 500ml (1pt) of clear water with just under a 50 second burst. These can also double as a torch and can be purchased from high-end outdoor adventure stores.
Disinfecting Water Using the Sun
The SODIS (Solar Disinfection) Method has been developed for developing countries as a low cost method for disinfecting water and eliminating diarrhea causing bacteria making it fit to drink. This method uses the sun’s UV rays to break down the bacteria and is endorsed by the World Health Organization. This technique involves filling clear PET plastic bottles with the suspect water and placing the cap firmly before laying the bottles out in the open, exposed to the sun, for the period of time specified below, depending on the weather conditions.
Suggested Treatment Schedule
Weather Conditions Minimum Treatment Duration
Sunny………………………………. 6 hours
50% cloudy………………………… 6 hours
50-100% cloudy…………………… 2 days
Continuous rainfall………………… Use rainwater!
This process can be hastened by laying a piece of corrugated iron against something so that is on a 45deg angle, facing the sun, and leaning the bottles against it so that they get maximum exposure to the suns rays.
If the water is very cloudy to begin with, it will need to be filtered prior to bottling. Once treated, the water can be stored in the bottle and consumed straight from the bottle.

This very effective technique could easily be adapted to both wilderness and urban survival situations and could be used by soldiers, troopers, scouts etc who are in an open top observation post (OP) and low on supplies. The advantage of using this method in a tactical/combat situation is that the is no need to alter the natural surroundings and no need for a fire; both of which would likely compromise your position and potentially your life. If used in this situation though, it is important that the containers are placed in a position low out of sight, perhaps even below ground level, so as not to produce shine or glare which could also give your position away.
When adapting this technique to a survival situation, the general method stays the same but the materials that you use may differ depending on what is available to you at the time. Plastic PET bottles may be substituted for glass or clear plastic bag, tied closed, and they may be laid against a rock or simply flat on the ground. Unfortunately for the planet, in this day and age, there are not too many places left on earth where you will not find some form of litter laying around. Fortunately, as a survivor, you can often find useful things amongst litter such as plastic PET bottles or even glass this will be even more prevalent along coastal areas. Of course you may need to improvise a cap/lid and you could make a plug this with a wad of fabric or leaves and then seal it over with mud or wild bees wax.
Clear bottles with a minimal amount of scratches work best.
This technique is very effective as:
- The yield is only limited by the size/amount of bottles that you have.
- The process doesn’t take too long
- The method can be carried out in a discreet, clandestine manner
- The method is effective in all weather conditions
- Requires low/no physical exertion
It is more efficient to melt ice than snow as ice requires less energy, therefore less fuel, to melt. Melting snow may be your only option. If so, an easy way of melting without a fire is to fill your drink bottle with snow and tuck it up under your jumper/sweater, whilst on the move and our body temperature will slowly melt it.
If you are too thirsty to wait for a whole bottle full to melt, you should melt a small amount of snow first by rubbing it between your palms, over your mouth, and drinking the drips.
In some situations, you may need to melt down sea ice for water. If this is the case, old, blue, sea ice with smooth edges is what you need to look for as it will be low in salt content and therefore good to melt and drink.
In the absence of old sea ice you could sea water in order to remove the salt and make it good to drink.
At a high level, Electrolytes help the body to retain fluid, regulating the hydration of the body as well as blood pH, and are critical for nerve and muscle function.
For example, muscle contraction is dependent upon the presence of calcium (Ca2+), sodium (Na+), and potassium (K+). Without sufficient levels of these key electrolytes, muscle weakness or severe muscle contractions may occur.
Serious electrolyte disturbances, such as dehydration and over hydration, may lead to cardiac and neurological complications
In a survival situation especially where heat and physical exertion are factors, the onset of dehydration can be hastened by not replenishing electrolyte, or at least salt, levels.
A simple electrolyte drink can be made by mixing the right quantities of salt, baking soda and salt a substitute for potassium in water then sweetening it with sugar. Unfortunately, in most survival situations, it is unlikely that you will have access to these ingredients.
For the survivor in the wild, your best bet for temporary replenishment of electrolytes is probably going to be ingesting around 10g (1/3oz) of salt daily. Salt alone will usually suffice if lost in the wilderness for a short time but the drink mentioned above would be a better option in an urban survival situation.
Chances are, that in a Survival situation, you will not have salt on hand so you will need to know how to find it. In some places, salt will be easier to find than others; near the coast, for instance, salt will be in good supply as the ocean is full of it; however, inland, your search may be more difficult.
Never drink seawater directly as your kidneys will not handle it. Either dilute it with fresh water at a rate of 1:6 seawater/freshwater. Salt is also the byproduct of evaporating or distilling sea water as described in the basics > water section.
Salt can also be extracted from seawater by soaking a piece of fabric, such as a shirt, in seawater and hanging it to dry. Once dry, salt residue will remain in the fabric which can then be fashioned into a ball and sucked on to ingest some of the salt.
Sea water holds approx 15g (1/2 oz) of salt per 470ml (1pint) therefore to meet the average daily intake of 10g (1/3oz), approx 320ml (1 1/3 cups) of seawater could be mixed with your daily freshwater. Young unripened coconuts hold about a liter of water and contain more electrolytes than most sports drinks.
Finding a supply of salt whilst inland will often be more difficult. Some wild plants have a salt content (see wilderness survival > wild food plants for more detail). Salt can be extracted from plants by boiling the plant until the container is dry leaving you with salt crystals on the bottom. These salt crystals are often black in colour.
Animal blood is also rich in vitamins, minerals and salt and is a valuable survival food which should not be wasted.
All animals eyeballs contain water which can be obtained through piercing it and squeezing out the liquid or by simply removing and eating it raw. Cooking the eyeball will remove any precious fluid contained in it so best consumed fresh and raw.
Fresh, drinkable water can also be found along the spine of any fish. To access it, gut the fish, lay it flat then remove the spine to reveal the water. (naturally large fish will yield the most water but be careful not to suck up the fish juices, if dehydration is a concern, as these are protein rich and will require additional fluid for your body to digest.)
This method could be the difference between life and death if lost at sea where supplies of fresh water are difficult to maintain.
Several liters of drinkable water can be found in the rumen of a camel and additional water can be obtained by squeezing it out the undigested stomach contents of the camel.
During drought in north-western Australia, local tribesmen dig for frogs that burrow in dry clay pans to stay cool. The frogs have a survival mechanism where they store water in their bodies. This water can be squeezed out and drank.
none of these techniques will be tasty but they will increase your chances of survival
This process is happening around us all the time. For example, nature uses evaporation to make clouds and condensation to make rain.
For the survivor, this can be a double edged sword. Humans experience fluid loss through breathing, talking, sweating, digestion and excrement but guess what; we are not alone. Most living things, experience fluid loss in this way and the survivor can harness this to increase their chances of survival. Heating anything which holds water will cause the water to evaporate.
In fact, for the most part, water just keeps on cycling around being consumed by all sorts living things, serving it’s purpose and then being released back into the ground or air as evaporation.
This trick is in catching it so that it condenses and provides you with a decent amount to drink.
Thankfully, with some knowledge the number of ways to collect this are limited only to your imagination.
Evaporating water and collecting the condensation will remove any impurities so therefore this process makes it possible to extract fresh, drinkable water from urine, seawater, contaminated water, poisonous liquid and sap, mud, clay etc.
The survivor will often be presented with the situation where the only liquid they have access to is unfit for drinking such as Sea Water, Urine, Contaminated or Poisonous Water and Suspect Plant Sap. Thankfully, by distilling these liquids, in a Still, the survivor can extract water which is fit to drink. The same method can be used to extract drinkable liquid from substance such as Earth, Foliage, Blood, Feces etc.
Although all stills work on the same basic principle of using heat to evaporate the water content from a substance, catching the water vapor and cooling it to condense the water droplets before channeling this into some form of container for drinking, there are many different ways of approaching stills depending on where you are and what materials & heating/cooling options you have available.
Some of the methods for creating a still are listed, in detail, below. There are also inflatable solar survival stills on the market which would be an ideal piece of kit to keep on a boat.
If you have fire as a heat source, the still can be a very efficient method of desalination of seawater and or decontaminating of water; or extracting water from poisonous liquid such as milky sap.
The tricky bit, when using fire as a heat source, is catching the water droplets as they evaporate. This can be done with a large plastic bag, tarpaulin or hoochie (folded into a cone shape) provided that the fire is low intensity (so as not to melt the bag or tarp).
The method for this is to make a tripod by lashing three 5-6ft sticks together and positioning it over the top of the fire. The plastic bag is then placed over the top of the tripod creating a cap.
Before placing the bag, or tarp, over the tripod, the opening edge of the bag/tarp must be folded back up, inside the bag so that it creates a catchment for the condensed water to pool.
Put the pot or improvised container of liquid on the fire and wait for the water to pool.
An alternative could be to use a
large piece of fabric instead of a plastic bag. Once the fabric is saturated, replace if with a dry piece. Let the saturated piece cool for a minute or two before wringing the water out into a container to drink.
You could also use a large flat leaf (e.g. A banana leaf) fashioned into a cone shape and pinned with a stick to catch the water vapor as it evaporates. A smaller tripod (20-30 cm) could be placed in the water container which would suspend the leaf cone above. Bamboo split in half lengthwise could be laid around the fire to catch the condensed water as it drips off the edges if the leaf cone.
The solar still method involves using heat from the sun to extract drinkable water from the ground, mud, foliage or feces via condensation.
Dig a hole in the ground about knee to thigh deep.
Place a container in the center of the hole and place cut vegetation around the container (you can leave out the vegetation if you don’t have any. So long as the ground is damp in the hole moisture will be drawn from the ground).
Cover the hole with a piece of plastic, weight it down with rocks and seal around the edges with sand, dirt, stones or mud. Place a small stone in the center of the plastic, above the container. Leave for a few hours.
If possible, you can place a piece of hose in the water container before sealing the hole so that you can drink the liquid without disrupting the still.
Inflatable Emergency Solar Still
There are a number of inflatable solar survival stills on the market which are an ideal piece of kit for boats and life rafts and are highly recommended for any voyage out to sea. Essentially they are an inflatable pyramid which uses evaporation and condensation caused by the sun to convert seawater into fresh drinkable water. These pack up nice and small for easy stowage and are available from most fishing and boating stores.
This method of collecting water uses evaporation and condensation to draw drinking water from a branch of a tree.
Place a plastic bag over the end of a branch (pick a branch with as much foliage as possible) and tie the opening of the bag tightly around the branch of the tree to seal it off.
Ensure that the branch is not pushed too far into the bag so that it is jammed up against the bottom of the bag as this may inhibit the condensation running down to the bottom of the bag.
Leave this for several hours. The sun will heat up the air inside the bag and this will cause the moisture in the tree branch to evaporate. The water droplets will condense on the inside of the bag and run down to the lowest point in the bag creating a small reservoir of water which is good to drink.
Set up as many of these as you can so that you get a good supply.
Like the solar still, the sweat bag still method can be used to draw drinkable water from foliage or contaminated water but without the effort of digging a hole.
Place a plastic bag (on it’s side) on the ground and brush the dirt off some stones and place them into the bag to form a small platform.
Place leaves, vegetation offcuts or foliage on top of the platform (this will keep the foliage up out of any water which pools at the bottom) and prop the top of the bag up with a stick to form a large hollow space filled with air. Ensure that you pad the top of the stick with fabric or a rock to stop it tearing a hole in the bag.
Seal the opening of the bag by tying and then just leave it to sit in the sun for a few hours.
The sun will heat the air inside causing the moisture in the foliage to evaporate and condense on the inside of the bag. The condensation will trickle down the inside of the bag and pool at the bottom.
This water will be good to drink.
You can also try substituting the foliage with a container of mud or urine.
Minimizing Fluid Loss
Fluid loss is unavoidable but there are steps you can take to minimize the amount you lose.
The following steps may seem extreme but they will help you minimize fluid loss an ultimately increase your chances of survival:
Exerting yourself will cause you to sweat to stay cool, which uses up precious fluid.
Don’t smoke or drink alcohol
If you smoke or drink alcohol, your body will use fluid to flush out your kidneys etc as your body goes into a detoxification process.
Laying directly on hot ground or heated surfaces such as rocks
If feasible, dig or clear a shallow trench in a shady spot and lay in it. The earth underneath will be cooler than the hot surface; but you must consider that the shade will move with the sun.
If water is extremely scarce. If water is available but in smaller quantities eat only small amounts avoiding fat (digesting fat requires a lot of fluid to break it down). If you eat without keeping your fluids levels up, your body will take fluid from wherever it is available, for digestion. Unfortunately this will be from your vital organs and will cause further dehydration.
Fluid is lost through evaporation. Observing the steam which comes off your breath on a cold morning will give you some indication of the amount which can be lost through evaporation.
Things you can do
Breathe through the nose and keep your mouth closed as much as possible
This will help you to avoid loosing fluid through evaporation. Your mouth has a much larger, damp, surface area and therefore, you will lose much more fluid through your mouth than your nose.
Keep water in your mouth
When moving over a distance in the heat, take a sip of water and hold it in your mouth, without swallowing it, as you travel. This will slow the rate at which you lose fluid through breathing and it will help to stop your mouth and lips from drying out.
Travel at Night
In warmer regions, travel at night or early in the morning, where possible, and rest in a cool place during the heat of the day.
Stay in shade where possible. Where there is no shade readily available, then you should erect something which will provide shade.
If there is no river, stream or pool of water on the valley or gully floor, look for places where clumps of green vegetation or trees are growing and dig there. You are likely to find water, or at least moisture, below the surface. Once you dig into the moist ground, leave the hole to rest for a few minutes which will allow the water to pool in the bottom for collection and drinking.
Water can also be found in dried riverbeds by digging on the outside bend. Chances of finding water in this situation are increased if there outside edge of the bend is protected by overhanging rock or log, or the area in which you dig is sandy; or has some form of green vegetation growing along the sides.
You should only need to dig about 50 – 70 cm (2ft) max. Any deeper and you run the risk of wasting precious body fluid through exertion. Survival is also about knowing when to cut your losses and continue you search elsewhere.
In coastal areas, digging about 100 mt (330ft) back from the high tide line will produce drinkable water. It will still be a bit salty but drinkable. The best results will come from sandy areas such as dunes.
Water seeping from rock walls (a seep) can easily be collected and can provide a reasonable amount of drinking water; ferns or vegetation growing out of a rock-face will often indicate a seep. The survivor can be almost certain to find a seep inside a cave or lava tunnel.
Collecting Water from a Seep
It is possible to sip the water straight from the rock, depending on how fast water is being released. Often there will only be a light seeping of water so you can also lay a piece if fabric or clothing over the seep until it is saturated and then wring the water out of it, either into a container or straight into your mouth.
Another method is to use a wick to divert the water into a container. To do this, place a container (cup, old discarded plastic bottle or even a broad soft leaf folded at the edges and pinned with twigs to form a container) securely near the seep (a man made container such as a discarded bottle could be hung from a string) lay a piece of string, cord, strip of fabric or shoelace across the rock where the water is seeping in such a way that it gets wet (this is the WICK). If the rock is vertical, secure the wick so that it does not fall off then put the hanging end in the bottle/container and leave it for a few hours. Before long, the wick will absorb the water to the point of saturation and the water will start to trickle nicely into the container. This method can be very effective and having a few of these set up can yield quite a good amount of water.
Springs occur where a flow of underground water breaks (or springs) through the grounds surface.
A spring can yield several hundred liters of water per day, even during a heavy drought, and can be a lifesaving find for the survivor.
Areas where granite rock bands or shelves break through the surface of the ground, and rocky cliffs should be searched for the presence of a spring. Look for the direction that the bands of rock are layered. Any spring water will actively move underground along the lines determined by the rock bands. This will give you some idea of where to look. A spring could look like a flow of water coming from a point in the rock or ground, or it could just look like a boggy patch of ground. In cliffs, it is worth investigating any areas where there is an excess of green vegetation growing.
At night or early morning, dew drops usually cover smooth surfaces such as leaves, grass, tree bark & and man made waste such as glass, tin/ iron and plastic. This can be an excellent supplementary source when collected. You can either soak this up with fabric or clothing or, if you are confident that it is safe, lick it directly from the source. Be careful though not to cut your tongue and some leaves are irritants and can cause your mouth to swell.
A reasonable amount of water can easily be collected by tying clean clothes around your legs and walking through long, dew soaked, grass at night or in the early morning. The liquid can then be wrung out into the mouth or a container.
Dew traps can be created by digging a hole in the ground about shin deep and placing a sheet of plastic, tarpaulin, leather or vinyl from a car seat or large leaf over the hole so that it sits in the hole and makes a depression. you will probably need to weigh down the edges with logs or stones. Leave it overnight and you will often find a pool of water in the morning.
Collecting Rain Water
When water is in short supply it is important not to overlook the small sources. Lots of little bits add up to a lot and these small water sources can greatly improve your chances of survival. Look for:
- Hollows in the fork of a tree, rock or ground where rainwater or dew may have pooled
- Trees, ferns and palms where broad leaves join the trunk as rain water or dew will often collect there
- Leaves which are shaped such that they hold small reservoirs of water
Rain traps are essentially the same as the dew trap however and can be used to catch and pool rain rather than dew, however when it is raining, any large smooth surface should be exploited (Tarpaulins, Plastic, Bamboo roofing, Large leaves etc) should all be fashioned in a way that they catch and channel rain from a wide area into the rain trap. Large sea shells, bamboo halves, sliced lengthwise also make good rain traps.
All rain water, no matter where you are in the world, is good to drink, as is.
If you are injured and cannot move, wrap a piece of fabric, like a strip torn from the bottom of a t-shirt, around the base of a tree and insert the loose end into the opening of a bottle or cup. The fabric will draw in moisture released by the tree and, once saturated, start dripping into the bottle/cup.
Watching for signs of water
There is a lot to be learned from watching animals as they go about their daily business I’m their environment. If you know what to look out for, you can pick up on tell-tail signs which will lead you to water, give you early warning if wild fire is near, help you to find salt and many more useful things.
- Birds flying low and fast are usually heading toward a water source.
- Birds flying from water are usually full and will often fly from branch to branch; fluttering and zig-zaging.
Honeybees nesting in the wild choose nest sites close to water supplies. Honeybees cannot survive without water as they use water to cool the hive, maintaining a temperature of around 35dec (C) or 95(F) preventing the wax from melting, water is mixed with pollen and honey to feed the young and to dilute their own food supply when the sugar levels are in excess of 50%. In hot climates, bees will require up to 2lt (2.1qts) per day. Bees will build their hive within 500mtrs of a sustainable watersource which could prove to be valuable to the thirsty survivor.
Honey is also a valuable survivor food which is rich in vitamins and a great energy source. Honey can be smeared over cuts providing protection from dirt and germs and properties which will hasten the healing process.
Tracks and Trails
- When you find converging game trails, following them, in the direction of the arrow that they make where they meet, will lead to water.
Man Made Objects
In the desert you should always look underneath any man made objects you may come across such as a sheet of iron or the like, it may have been placed there on purpose to cover the entrance of a well or bore. This is common practice amongst locals in arid places.
Three (3) Weeks without food. But only. . .
Three (3) Days without water.
When water availability is a concern, your first priority is to conserve the water that you already have contained in your body plus any supplies that you have left. There are some tips on conserving bodily fluid in the ‘fluid loss’ and ‘electrolytes (salt)’ articles further on in the water category.
Water can be sourced from most places but you need to know where to look.
Water is at the top of the priority list so you need to ensure that you secure an adequate supply as soon as possible (Not once you have already run out).
Whilst it is preferable to find a source of fresh running water, this will not always be an option. All water can be treated and made drinkable though so even if its not an ideal source, it should be collected and treated by using one of the methods described in this section.
- Does not have any living plants growing in or around it
- Has animal, reptile or fish bones or carcasses in or around it
- Has white chalky ring/s around the edges
These are often signs of chemical contamination and this water will need to be distilled before it is fit to drink. It is always advisable to boil water from pools.
- Never drink seawater without diluting as this will lead to kidney failure.
- Only ever drink urine as an absolute last resort.
Where the situation permits, you should always boil all water to avoid picking up any nasty stomach bugs which could causes vomiting and diarrhea which will cause you to lose fluid, which you cannot afford to lose.
Exertion, heat, injury, or an illness can all contribute to increases in water loss.
Dark yellow urine indicates dehydration.
Once you find a good source of water, Be careful not to drink too much too quickly as this will usually result in you throwing up, if you are at all dehydrated, resulting in further fluid loss and further dehydration. You should take it in small frequent amounts allowing your body to accept and absorb it.
