Immediate Water Provision
Ensuring a reliable and clean water supply is paramount in any urgent or emergency situation. Here are some methods to secure water immediately, with minimal resources:
-
Urban Water Access
:
- Sillcock Keys : In urban environments, access water from commercial buildings using sillcock keys. These keys open water spigots that lack traditional handles, typically found on the outside of buildings. This method is invaluable when municipal water is still running but access is restricted.
- Public Fountains and Buildings : Use water from public fountains, restrooms in public buildings, and other accessible infrastructure.
-
Foraging and Collection
:
- Natural Water Sources : Locate natural water sources such as rivers, streams, ponds, and lakes. These sources can provide significant amounts of water but require treatment before consumption.
- Rainwater Harvesting : Collect rainwater using tarps, buckets, or any large surface area. Ensure collected water is treated or filtered before drinking.
-
Water Filtration
:
- Portable Filters : Use portable water filters like the LifeStraw or Sawyer MINI. These filters are compact, effective, and require no power source, making them ideal for immediate use
- Gravity Filters : Gravity-fed systems like the Royal Berkey can filter larger volumes of water and are effective in stationary settings
-
Water Purification Tablets
:
- Chemical Purification : Use water purification tablets such as Potable Aqua or Katadyn Micropur MP1. These tablets are lightweight, easy to use, and can purify water quickly, making them ideal for emergency kits
- Boiling : Boiling water for at least one minute (three minutes at higher altitudes) is a reliable method to kill pathogens. However, it requires a heat source and suitable containers.

5 Ways to Collect Water in the Wild
Running out of water while in the wilderness could become a life-threatening scenario if you’re unable to find a new source. Here are five methods for finding water you can then purify and drink:
- Collect rainwater . Precipitation in most rural areas, far from highly polluted cities, can provide a significant amount of drinking water. Look for places where rainwater collects in natural aquifers (stores of groundwater just below the earth’s surface) or build your own rainwater collection system using a tarp and a sediment filtration system.
- Follow signs of green vegetation or wildlife . Desert plants, cacti, and shrubs are great vessels of water conservation. Seek out groupings of such plants or follow animal tracks to find water in dry, arid climates.
- Melt snow and ice . Boiling water from ice or snow will remove the most harmful contaminants and bacteria while also protecting you from hypothermia. Be advised that eating snow or ice can dramatically drop your body temperature, putting you at risk in a cold-weather survival situation.
- Search for signs of water underground . Lost caving and spelunking enthusiasts have survived for multiple days by licking cave walls to take in moisture. Small amounts of moisture and condensation can collect on stalactites or in crevices in the rockface of a cave, providing a stranded person enough pure water to survive for a few days.
- Trap condensation from plants . Water helps vegetation move nutrients throughout its plant structures. Then, through the process of transpiration, plants release the excess water into the atmosphere. Tie a plastic bag around the limb or branch of a small bush to trap this released moisture and supplement your drinking water supply.
How to Distill Water Using a Solar Still
In certain situations, it’s possible to collect and distill enough safe drinking water to survive by crafting a solar still (condensation trap) from a plastic sheet and a water bottle. As moisture from the ground evaporates, it collects on the sheet, then trickles into the vessel. The sun facilitates evaporation and causes impurities (including salt) to remain behind after the vapor-to-condensation process. To make your own rudimentary solar still, follow these steps:
- Dig a hole . It is unsafe to drink groundwater near the coast because nearby seawater may have contaminated local surface water. Seawater, or salt water, is toxic due to its high salt content. A solar still can help you to collect fresh water or to desalinate salt water, depending on where you choose to construct your still. Use your hands or a shovel to dig a hole roughly two to three feet down into moist sand or mud (for example, in a dry river bed) until you see water rising from the hole's floor.
- Establish a collection point . Place the water bottle or container at the center and drape a piece of plastic over the hole. You can place weights around the perimeter of the plastic sheet to hold it in place and add a small weight of sand on top of the plastic above the collection point.
- Form a tight seal around the edges of your solar still . Create a sealed, greenhouse-like structure above the groundwater source to allow the heat from the sun to evaporate the water below. Water droplets will condensate and collect on the underside of the plastic. These droplets will then run toward the central, low point of the plastic and drip into your collection container. If you are desalinating salt water, the amount of salt this process removes largely depends on the strength of the sun.
Urban Environments and the Sillcock Key
If you’re in an urban environment, buy a sillcock key!
What is a sillcock key?
A sillcock key is used to access water from the sides of buildings. You’d access the water from spigots/valves that look like this:
This spigot gives the business owner access to water on the outside of their building to use for cleaning, watering plants, etc. Most buildings have them but not all of them use a sillcock key. Some of them are regular turn spigots with a hose attached, and many of them have a panel over them that says “WATER” or something like that.
They use the sillcock key method to deter the general public from accessing the water. The general public is assumed not to even know what type of key would access that water, let alone own one.
When should you access water from the sides of buildings?
Technically, when you’re taking water from those spigots, you’re taking water that is paid for by the building. Thus, unless you ask permission, you’re taking water that belongs to the owner of the building.
I would only access those outside spigots in times of an “emergency.” Don’t just go walking up to them on a regular everyday basis, especially if you don’t have permission from the building owner, or if you do, do it quick and be wearing shoes with laces.
Where should you keep a sillcock key?
Keep one in your bug out bag, vehicle, EDC bag and even at home. Keep them anywhere and everywhere. You never know when they may come in handy.
How long will the water be good for?
As long as water is flowing, the water will be fine to consume, however, I suggest you sanitize it anyway, just to be safe. In some cases, the water may have been sitting in the pipes for a bit.
Where can you get a sillcock key?
You can purchase a 4-way sillcock key from any hardware store like Home Deport or Lowe’s, or online. Again, don’t be ‘that person’ that abuses the sillcock key by using it on a regular basis, especially if you don’t have to.
It doesn’t matter where you live because even in suburban or rural areas, there are buildings with water spigots on the outside. Take a walk around your area and spot the water access points along the buildings. Whether they use a sillcock key or not, they’re certainly useful to know in emergency situations.
I would highly advise that you have at least one of these somewhere. Don’t let the weight deter you. Water is life. It’s far more valuable than people realize. In an emergency, it’s one more resource to access water.
I have one in my everyday bag and it’s never made an impact on my overall weight, nor have I ever complained that it’s in there because of the weight. I understand the importance and that it’s worth their weight in gold.
Long-Term Water Provision
Sustainable, long-term access to clean water requires planning and resourcefulness. Here are strategies for achieving this through individual actions:
-
Urban Strategies
:
- Rainwater Harvesting Systems : Install rain barrels and other rainwater harvesting systems. These systems can be connected to downspouts to collect and store rainwater for future use.
- Greywater Recycling : Implement greywater systems to recycle water from sinks, showers, and laundry for irrigation and other non-potable uses.
-
Rural Strategies
:
- Wells and Boreholes : If you have access to land, consider drilling a well or borehole. This provides a reliable source of groundwater that can be treated for drinking.
- Surface Water Collection : Create ponds or reservoirs to collect and store surface water. These can be used for irrigation and, with proper treatment, for drinking.
-
Filtration and Purification Systems
:
- Household Filters : Install household water filtration systems to ensure a continuous supply of clean water. Systems like the Royal Berkey provide high-capacity filtration and are suitable for daily use
- Atmospheric Water Generators : Use atmospheric water generators to extract water from the air. These devices are particularly useful in humid climates and can provide a steady supply of drinking water
-
Water Storage
:
- Storage Containers : Use food-grade containers to store water. Ensure they are kept in a cool, dark place to prevent contamination.
- Emergency Reserves : Maintain an emergency water reserve. The CDC recommends storing at least one gallon of water per person per day for at least three days.
-
Skill Development
:
- Water Treatment Skills : Learn various water treatment methods, including boiling, filtration, and chemical treatment. This knowledge ensures you can safely handle any water source.
Basic Water Storage
Clean, potable water is a life necessity. Our bodies need it to survive. We use it to clean ourselves, preventing illness and infection. We also use it to prepare food. Having plentiful water after a disaster cannot be overemphasized. Experts say that we’ll need one gallon of water per person per day. To my way of thinking, that’s almost absurdly minimal. I’d suggest at least one-and-a-half to two gallons. More is always better. The problem is that water is heavy and can be difficult to store in mass quantity. You can’t shrink it down either. It takes up a lot of space.
Calculate Your Water Needs
Regardless of where you live, at a minimum, your group should have ten days’ worth of potable or purifiable water per person on hand at any time. For a group of four, that amounts to eighty gallons of water. That’s four twenty-gallon water bottles.
If you have limited storage space in your home, that might be the maximum you can store. If you live in an area that’s susceptible to catastrophes like hurricanes, blizzards, or earthquakes that could disrupt water supply for up to a month, you should plan to have more water on hand, up to thirty days per person.
Discuss with your group what you can realistically store in the space you have. If you follow all the storage goals in the weeks to come, you’ll end up with about fifty-two gallons of water per person. That’s potentially enough for three full months of off-the-grid (and pipes) living. If you don’t have the space to store that much water, simply come up with a realistic, safe goal and then cut off your storage there. Don’t forget to rotate your water supply if you’re not purchasing sealed water. That’ll keep your water safe and potable.
Look back to the list you made for how much water you have stored right now. Did you include the contents of your water heater? The average water heater holds about thirty gallons or so. That’s enough to last a group of four a few days, and it’s likely already there, without any planning on your part.
How many days could you last on the water you have stored right now? Do the math, I’ll wait. If you have four people in your group and you have forty gallons stored, at two gallons per day you have enough for five days. And that’s figuring nothing more than occasional sponge baths for cleanup.
What are the best ways to store water? I like to use cleaned-out soda and juice bottles. A two-liter bottle is roughly half a gallon. I like them because they’re both easy to store and not too cumbersome to use as is. There are, of course, containers specially made for storing water. I know several discount retailers that sell seven-gallon containers in their sporting goods sections, and those containers are nice to have. Most of them have a built-in spigot, making them easy to use. But again, water is heavy, and even a seven-gallon container takes a bit of oomph to move.
You could, of course, purchase commercially bottled water. But this can be expensive, and the water isn’t much better than what’s available in many homes free from the tap. That said, for some people this might be the most feasible option.
Some folks advise that if you have the time to do so in an emergency, you should fill up your bathtub. Not a bad plan, but how many of you have bathtubs clean enough to drink from at any given time? Of course, the water from the tub could be used for other purposes such as cleaning. What you’ll want to do, though, is cover the filled bathtub to keep dust and other stuff out of the water. You can buy shower curtain liners at most dollar stores, and these would work well for that purpose. Just drape one over the tub and use books or something on the sides to keep it in place. Also, if you go this route in an emergency, use only the cold faucet tap so you don’t empty your water heater.
The Waterbob
There’s a product specifically designed for storing emergency water in the bathtub. The WaterBOB is a large plastic bladder that you roll out on the bottom of your tub, then fill from the faucet. It holds up to one hundred gallons and comes with a handy siphon pump for transferring the water from the bladder to pitchers or jugs. Since it’s sealed, there’s no worry about debris falling into the water. This would provide an excellent backup to your other water storage. But it should only be considered a backup. Obviously, it’ll work only if the faucets are still running. Should you not be home at the time of the initial crisis, you might miss your window of opportunity to fill the WaterBOB. So keep storing water as instructed. You can find the WaterBOB at this website: www.waterbob.com .
Storing Your Water Safely
Your water should be stored in an easily accessible location. A basement is OK, if you’re ready, willing, and able to carry that water up and down stairs. A better solution might be closets, pantries, that sort of thing. Someplace cool and dark is best. Stored water also needs to be rotated regularly. Figure on a six-month schedule for rotation. Use the old water for houseplants, pets, and gardens. This doesn’t apply to commercially bottled water. Kept sealed, this water will stay fresh pretty much forever.
Important Note About Water Storage
As we go through each of the following sections, you’ll be instructed to continue setting aside water for each member of the group, one gallon per person per week. However, it’s also time to start rotating your supply to ensure that the water you’re storing doesn’t get stale. Here’s what you should do. Your water should be stored in such a way that you can easily determine which bottles are the oldest. Going forward, you’ll remove one gallon from your storage and pour it into the water dish for the pets, use it for cleaning, or pour it into the garden. You’ll then replace it with two gallons of fresh water. This replaces the gallon you took out as well as adds another gallon to storage. This way, you’re constantly using up the oldest water as well as adding fresh to the stockpile. Note: Do not use milk jugs. They’re not designed for long-term storage and degrade rather quickly, developing pinholes in them. But if you’re storing purchased bottled water, rather than filling your own containers, there’s no need to rotate the supply. Commercially bottled water will remain fresh as long as the seals on the bottles are not 21 broken. So, if you’re storing cases of bottled water that you’ve bought at a warehouse store or grocery store, you can skip the whole rotation thing and just concentrate on building up your supply.
Tasks
- Determine a water-storage goal, in terms of how long you feel you may need to provide for your own water needs in the event of a disaster. Calculate how much water you should have stored. Remember, you’ll need 1.5 or 2 gallons per person per day.
- Work out a plan to achieve your storage goal. Begin or continue to gather containers that’ll work for your situation. Be sure they’re clean.
- Figure out a rotation schedule. What you want to avoid is dumping large quantities of your stored water all at once. The six-month rule is a guideline, not set in stone. Use up and replenish a few gallons each week to keep your supply fresh.
Water Filtration and Purification
We talked about the importance of storing water. Indeed, storing water is one of your ongoing tasks. Running just slightly behind this in importance is having the ability to filter and purify additional water supplies. There are, of course, many natural sources of water, such as lakes, rivers, rain, and snow melt. But no matter how absolutely crystal clear that water may be, it should still be filtered and purified.
One of the best investments one can make is to purchase a water-purification system such as a Big Berkey Water Filtration System. Yes, it’s expensive, but it’ll do the job far better than you may be able to accomplish without it. Other brands to look for are Katadyn and Aquamira.
As you compare costs and brands, take a hard look at the specs for each unit. You’re going to want something that will filter sufficient quantities of water to suit your needs. For example, if you have a group of five, you’re probably going to want a system that will do more than a gallon an hour. You also want to consider the size of the organisms the system will filter out. You want a filter that will remove at least down to the 0.2–0.3 micrometer range. That will handle the bad critters like cryptosporidium and giardia.
Unfortunately, such filtration systems don’t work so well on viruses, which tend to be considerably smaller. With that in mind, you may want to incorporate an additional step of chemical treatment or boiling to ensure safe water.
There are also many ways you can purify water without using such devices.
Boiling Water
You can bring the water to a rolling boil. It used to be that experts recommended letting the water boil for several minutes, but now the latest information says that the water needs to be brought only to a rolling boil. Doing so is enough to kill off any harmful organisms. Naturally, this method requires enough fuel to boil large quantities of water as well as the time to not only boil the water but allow it to cool enough to handle or consume. When at all possible, though, use boiling to disinfect the water—it’s the surest way to provide clean water.
Bleach
Nonscented chlorine bleach will render questionable water potable. Add sixteen drops (1/8 teaspoon) of bleach to a gallon of water, swish it around, then let it sit for about a half hour. If the water still has a faint chlorine smell, you’re good to go. If it doesn’t, repeat the process. If the water is very cloudy or very cold, double the amount of bleach. Bleach is fairly inexpensive, but it does have a limited shelf life. Once the bottle is open, expect full potency for about six months before it begins to degrade.
You can make your own bleach mixture using calcium hypochlorite, also known as “pool shock.” Here are the instructions for doing so, from the Environmental Protection Agency’s website:
Add and dissolve one heaping teaspoon of high-test granular calcium hypochlorite (approximately ¼ ounce) for each 2 gallons of water, or 5 milliliters (approximately 7 grams) per 7.5 liters of water. The mixture will produce a stock chlorine solution of approximately 500 milligrams per liter, since the calcium hypochlorite has available chlorine equal to 70 percent of its weight. To disinfect water, add the chlorine solution in the ratio of one part of chlorine solution to each 100 parts of water to be treated. This is roughly equal to adding 1 pint (16 ounces) of stock chlorine to each 12.5 gallons of water or (approximately ½ liter to 50 liters of water) to be disinfected. To remove any objectionable chlorine odor, aerate the disinfected water by pouring it back and forth from one clean container to another. ( http://water.epa.gov/drink/emerprep/emergencydisinfection.cfm )
This method is appealing because pool shock is very stable and lasts a long time if it’s kept dry and cool. It can also be very inexpensive, especially during clearance sales at the end of summer. Given that you’ll need to use only a very small amount to make your purification mixture, even one or two packages of pool shock will last you a good long time.
Water-Purification Tablets
Naturally, any camping supply store carries a wide range of water-purification tablets. These do work well, but you’ll be able to disinfect only small amounts of water at a time. You’ll go through quite a few tablets in just a few days if this is your primary disinfection method.
Water Bottles with Built-In Filters
There are also different types of water bottles with the filtration unit built in, such as those sold under the Aquamira brand. Great to have and recommended, but don’t count on using them to provide large quantities of clean water at any one time.
Of course, before disinfecting the water, it should be filtered to remove the larger “stuff” that may be present. One of the best ways to do this is to first let the water sit long enough for anything floating in the water to settle to the bottom of the container. Then, pour the water through one or two coffee filters. I have also seen elaborate DIY setups using successive layers of small gravel, sand, and charcoal before going through coffee filters. If you have the time and the means, this is not a bad approach.
Clean water is absolutely essential to survival. While storing quantities of it is one of the first steps in a preparedness plan, you need to have the means to make found water potable as well. Few of us have the means to store all the water we’ll need during and after a major disaster.
Water Distillation
Distillation is a process where you separate the components of a liquid from one another. When you distill water, you can separate the pure, drinkable water from any contaminants (such as salt, bacteria, or minerals) that might affect the water's taste or potability. A water still works by first heating water until it turns into steam, then collecting the steam in tubes or on a glass plate, and finally condensing the steam into new, purified water droplets that can be collected in a clean vessel. [1] You can purchase a water still at many hardware stores, or you can build your own out of common materials.
Stove-top Water Still
Just buy one if you really want one. If you need a long-term water distiller because you have running water from the tap or access to water but you need to make sure it’s drinkable (cough cough Flint, Michigan) it’s expensive (about 80 bucks) and slow, but it gets out heavy metals and chemicals unlike boiling and doesn’t require purchase of new filters or other recurring costs besides requiring ice and a working stove or other heat source. It is also entirely metal and will basically last forever. It also avoids the sometimes-gross taste of filtered water or chemically-disinfected water.
However, these benefits are also achieved with a solar still. This obviously requires heat and sun, though.
Distilling Water with a Plastic Water Bottle
How to Desalinate & Distill Water Using Simple Tools
In a survival situation, having access to drinkable water is crucial. Here's a step-by-step guide to desalinate water using simple materials you can find around you.
Materials Needed:
- Two plastic bottles (one larger than the other)
- A knife or a sharp object
Steps:
-
Find Two Bottles:
- Locate two plastic bottles: one larger and one smaller.
-
Prepare the Larger Bottle:
- Cut the bottom off the larger bottle. Keep the cut piece as it might be useful for other purposes.
- Fold the cut part of the larger bottle inwards to create a pocket. This pocket will be used to catch the distilled water.
-
Prepare the Smaller Bottle:
- Cut the smaller bottle horizontally near the top to create an opening for the saltwater.
-
Assemble the Desalination System:
- Fill the smaller bottle with saltwater.
- Place the larger bottle over the smaller bottle, ensuring the cut bottom of the larger bottle covers the top of the smaller bottle completely.
-
Set Up for Condensation:
- Place the assembled bottles in direct sunlight. The heat from the sun will cause the saltwater to evaporate, and condensation will form on the inside of the larger bottle.
-
Collect Fresh Water:
- The condensation, which is now fresh water, will collect in the folded pocket inside the larger bottle.
- To collect the water, gently tap the bottle so the water droplets drip down into the pocket.
-
Retrieve and Drink:
- Once enough water has collected, turn the larger bottle upside down. The fresh water will gather in the lip you created by folding the plastic.
- Open the larger bottle and pour the collected water into a container for drinking.
-
Repeat the Process:
- Set up multiple desalination systems with additional bottles to increase the amount of fresh water collected.
Tips:
- Ensure the setup is stable and secure to avoid spilling the collected fresh water.
- Place the system in a sunny location for the best results.
- Regularly check and maintain the setup to ensure optimal performance.
This simple desalination system can be a lifesaver in emergency situations where access to fresh water is limited. By utilizing readily available materials and the power of the sun, you can produce drinkable water from seawater.
Making a Medium Solar Water Still
Another solar still design more suited for environments where you have access to saltwater or contaminated water, but need to passively purify it looks like this:
A basic solar still typically consists of two water troughs – one water trough is filled with contaminated water, and the other is kept empty to collect purified water. A piece of glass is placed across the top of the contaminated water trough, angling directly down into the empty water trough. The bottom of the water trough filled with contaminated water is usually covered with black paint to help absorb solar energy from the sun.
Step One: Assemble your materials
Most of the materials you require for a solar water still can be acquired at a hardware store or home-brewing supply store. A solar water still will require more handiwork and assembly than a stove-top water still, but a solar water still can come in handy in emergency situations where you do not have working electricity or gas. Your materials should include:
- Plywood (4 feet by 8 feet)
- One sheet of high-finish, tempered glass (27.25 x 22 inches)
- Wood glue
- High-temperature black paint
- Screws
- Drill with drill bits
- Caulk
- PEX tubing (2 feet)
- Rigid insulation
- Two long, flat glass baking pans
Step Two: Cut the plywood into several pieces to form a wooden box.
The base of your solar water still will be a wooden box made out of plywood. The top of the box should have a slight incline so that the glass top will be at an optimal angle. Your box will be made of five different plywood pieces:
- A bottom base that measures 23.25 x 19 inches
- A short end piece that measures 5.75 x 20.5 inches
- A long end piece that measures 9 x 20.5 inches
- Two trapezoidal side pieces that measure 9 1/8 inches tall (at the long end), 5 1/8 inches tall (at the short end), and 26.75 inches wide
- Note that a circular saw set to a 9 degree angle can help you cut the trapezoidal pieces correctly
Step Three: Assemble the rigid insulation
Cut a piece of rigid insulation using the same measurements as the bottom base of your plywood box. Screw the insulation to the plywood base.
Step Four: Assemble the wooden box.
Using screws and wood glue, assemble all of the pieces of the wooden box together, except for the long end piece. The long end piece will be your hinged door and must be attached using separate door hinges. Make sure that the door faces the short end and that the two trapezoidal pieces face each other. Use caulk or weather seal to make sure all of the edges are airtight.
Step Five: Paint the inside of the box black.
High-temperature black paint will help the water inside the still heat up in the sun, allowing it to evaporate more efficiently. Coat the inside of the box thoroughly. Allow the painted box to dry for 3-5 days to ensure that all fumes and toxins are aired out before you finish assembling the still.
Step Six: Drill a hole for the water tube
Your PEX tubing will be used to collect the water droplets that form inside the solar still and pour them into a separate, clean container. To insert the piping into the box, drill a hole the same diameter of your tubing 1/2 inch down from the top of the box at the short side of the trapezoid. Only make a hole in one of the trapezoidal pieces: not both.
Step Seven: Assemble the water tube
In order to collect water effectively, your water tube must be open inside of the box (to collect water drippings) but closed outside of the box (to keep the water clean). Mark 19 inches on your PEX tubing, and slice it in half. This should leave you with a piece of tubing that is open for 19 inches and closed for 5 inches. Screw the open piping inside the short side of the box using three screws, making sure that a few inches of the closed tubing are able to stick out through the pre-drilled hole. [9] Slope it down to a point 1/4-inch below the starting height to make sure the water flows out of the box properly.
Use caulk or sealant to make sure that the piping fits snugly in the hole you drilled and that the open tubing is securely fastened to the plywood.
Step Eight: Add the glass roof
The glass plate will fit at a slight incline into the top of your water still, allowing water droplets to form inside and then flow down the incline and into your PEX water tubing. From there, the purified droplets will leave the still through the closed piping and into a separate container. After making sure your glass plate has been thoroughly cleaned, caulk the outer edges of the glass thoroughly. Then gently lay it on top of your assembled box. If you have measured correctly, the glass roof should be at a 5-10 degree angle, which is ideal for water collection. [12]
You can use a temporary stop or painters tape to secure the caulked glass roof until it has dried thoroughly.
Step Nine: Place glass pans filled with water inside the still.
One of the sides of your still has been attached with hinges, which will allow you to open and close the door at will. Fill two flat, glass baking pans with water (1-2 inches or so) and insert them into your assembled still. Tin foil containers or other non-absorbent materials work too, but the key thing is that they are wide and flat. This will serve as the water source that will be purified by the sun.
Step Ten: Sanitize water containers for long-term storage.
Note on Water Distillation
If you plan to store your distilled water for long periods of time, be sure that your storage container has been thoroughly sanitized. Dilute one teaspoon of bleach in one gallon of water. Use this solution to thoroughly coat the inside of your storage container. After about 30 seconds, pour out the bleach solution. Let your container air-dry or rinse it with clean water. [14]
- Distilled water can be used not only for drinking but also for making soap, filling steam irons, and in automobile repairs. [15]
- Make sure that all components are fully dried and airtight before first use to prevent leaking and warping.
- Clean all components of your water still thoroughly before distilling drinking water. They might be dusty or dirty.
- The materials you use in your water still should all be heat resistant to prevent warping, melting, or leaching chemicals into your purified water. Make sure your collection buckets, tubes, and lids are all heat-proof.
- If you plan on drinking your distilled water, be sure that your materials are considered food-safe. A number of building materials (such as vinyl and plastics) are not toxic to touch but might leach toxins into your water.
- It is not recommended for you to use a homemade water still for alcohol distillation. You might inadvertently create the toxin methanol, which can cause blindness when ingested. The fumes are also extremely flammable and dangerous.
- It is not recommended for you to drink only distilled water for extended periods of time. While distilled water can help you stay healthy in certain short-term situations (such as a Cryptosporidium outbreak or temporary water contamination), distilled water also deprives your body of essential minerals and nutrients. [16] If it is safe for you to drink non-distilled water, you should do so.
- If your water source has been contaminated with fuel or toxins, you should find another source of water: your home treatment plan might not work well enough to keep you safe. [17]
- Be careful about touching the components of your water still: they get very, very hot during the distillation process.
