Chapter 4: Water |
General Facts About WaterAstronomers often refer to the Earth as the "Blue Planet," so abundant is the water that covers 70% of the planet's surface. Ninety-seven percent of the earth's water is in the oceans, but that water is not readily available for human use because of its high salt content. Of the 3% that consists of fresh water, two thirds is locked in glacial and polar ice. That leaves only 1% of the earth's water available for human use.
Scientists believe that life began in the oceans. If that is true, then we apparently took part of the oceans with us when we left our watery birthplace, for fully 70% of the human body is made up of water. A newborn's body consists of 77% water while an adult's consists of approximately 70%. The percentage gradually decreases throughout life with the elderly's body consisting of only 50% water. |

Want to stay young? Drink plenty of pure water! Every cell in the human body contains water, which is
necessary for virtually every chemical reaction required to keep us alive
and healthy. We can live for weeks without food but only a few
days without water. Water is needed to carry oxygen and nutrients to the
cells, to dissolve minerals, for lubricating the joints, moistening and
protecting body tissues and organs, and for flushing out waste products.
When we don't get enough water a condition known as dehydration
occurs. The symptoms of dehydration include thirst, less frequent urination,
dark colored urine, dry skin, fatigue and lightheadedness. The symptoms
of dehydration in children include dry mouth and tongue, no tears when
crying, no wet diapers for 3 hours or more, sunken abdomen, eyes or cheeks,
high fever, listlessness, irritability and skin that does not flatten
when pinched and released. Today, with growing populations and increasing pollution of our natural resources, we are facing a water crisis. The World Health Organization estimates that over one billion people lack safe drinking water, and water borne diseases are responsible for the deaths of 4,000 children every day! It is estimated that the average American uses about 50 gallons (190 l) of water per day. This includes not only water for food preparation and drinking, but all other uses as well, including showering, flushing the toilet, etc. During an emergency, when our municipal water is cut off, we are obviously going to have to make do with much less! The medical profession tells us that we should drink 8 glasses of water a day. The US National Research Council recommends a total of 2.7 liters (about 3 quarts) of water (including food sources) for women and 3.7 liters (about a gallon) for men. The actual amount of water we need will vary depending on temperature, humidity and activity level. In hot climates and when the level of activity is high, the human body may require up to two gallons (8 l) of water per day to avoid dehydration. Survivalists usually agree that when computing your water needs during an emergency you should plan on one gallon (4 l) of water per person per day. This allows for drinking, food preparation and minimal washing (such as sponging off.) During hot weather and especially when the activity level is high this amount should be doubled. A water dispenser like the one pictured, along with a few extra bottles of purified water, will provide emergency water for drinking and food preparation during a short-term emergency. We keep this unit in our kitchen for our everyday drinking water needs, refilling it with a countertop reverse osmosis filter. When your municipal water fails, one of the easiest places to get a small amount of emergency water is from the water still remaining in the pipes in your house. First shut off the main water valve into your house to prevent the water from flowing back into the water main. Then open a tap at the highest location in your house, to allow air to flow into the pipes, and collect water from a tap at the lowest location in your house. You may also be able to use the water stored in your water heater by collecting it from the drain tap located near the bottom of the unit. |

Preparing for a DisasterSince water is so vitally important, and because so much of it is needed for survival, we should prepare for a disaster by storing as much as we practically can, and by making preparations for collecting additional water. Since the water we collect will most likely be contaminated, we will also need to be prepared to filter and purify our water. Polluted water is extremely dangerous. It has been estimated that worldwide, water borne diseases are responsible for about half of all hospitalizations. Bacteria in our drinking water is the cause of many deadly diseases, such as cholera, amebic dysentery and life-threatening diarrhea. Even in the best of times the water in our rivers, streams and lakes is unsafe for drinking. Imagine how much worse it will become when our sewage treatment systems are not working properly. There is no doubt that more human wastethe primary source of dangerous disease-causing bacteriawill enter our water supply after a disaster strikes. Even water collected from rain and snow, due to pollution in the air, must be treated before it is consumed. Survivalists tell us that rainwater should be treated pretty much the same as pond or river water. |

Storing WaterEven the purist water will go bad due to bacterial growth when stored over an extended period of time. Whenever water is stored for an emergency it should be rotated and replaced regularly. The old water should be used (I use it to water my garden when rain is scarce) and the storage containers should be washed and rinsed and replaced with fresh water each year. The shelf-life of stored water can be extended by adding a small amount of household chlorine bleach (e.g., Clorox.) To prepare water for storage add 4 drops of chlorine bleach per gallon of water (1 drop per liter). For larger vessels add one teaspoon of chlorine bleach per 30 gallons (4 cc per 100 liters). Don't worry about being exact with your measurements. Avoid buying chlorine bleach with scents or other additives. Use only plain old-fashioned chlorine bleach. Water can be stored in many different types of containers, from small plastic bottles to 55 gallon (200 l) drums. Old milk containers are not recommended because they can never be cleaned thoroughly enough to prevent spoilage from bacteria. Five gallon plastic containers are great. They will also come in handy if you need to transport water. Fifty-five gallon (200 l) plastic drums are ideal if you have room to store them. These can be quite expensive if purchased new, but there are always used drums available if you search for them. I have purchased used drums for as low as $10 each from retail outlets, and for as little as a few dollars each at estate sales. Be sure that your drums have not been used to store toxic materials. All plastics are slightly porous and it is impossible to completely remove the toxins from the plastic. Beverage bottling companies usually receive their ingredients in food-grade plastic drums that are perfectly suitable for water storage. If you are unsure about what was originally stored in your plastic drum, then use that drum for non-potable water only. Non-potable water will come in very handy for washing and for flushing your toilet. I suggest that you use a large permanent marker to mark your water storage containers as either "Potable" or "Non-Potable." |

Purifying WaterWe will now consider the various ways that water can
be filtered and purified. As we will see, some methods do not lend
themselves well to emergencies. The method you will use will depend on
the equipment you have available and how dirty your water is. There are three basic ways to purify water:
Mechanical Filtration

Conserving WaterAs we saw earlier, due to overpopulation and pollution, clean fresh water is a diminishing resource worldwide. The U.S. Environmental Protection Agency (EPA) states that runoff from driveways, streets and yards is the single biggest threat to the health of American waterways. According to the EPA, Americans apply 67 million pounds of pesticides to their lawns every year. Agricultural run-off of fertilizers and pesticides has created a dead zone in the Gulf of Mexico where the Mississippi River enters and for miles out into the Gulf. Even during normal times water should be conserved as much as possible, and efforts should be made to minimize the pollution of our streams, lakes and oceans. In the future, hopefully more organic methods will be employed for growing crops and the use of chemicals can be reduced. Homeowners can reduce pollution of our fresh water by refraining from using chemical fertilizers and weed killers on their lawns. Ironically, two of the weeds that people find most troublesomedandelions and plantainsare also edible plants that can serve as excellent survival foods (more on these "weeds" later.) During times of emergency, when the municipal water
has ceased to flow, even more attention will need to be given to water
conservation. Toilet flushing, for example, will have to be kept to a
minimum. Excessively long and frequent showers will have to be eliminated.
We will also have to learn how to reuse water as much as possible. If our sewer systems are backed up, care must be taken
to insure the proper disposal of human and animal wastes. We must endeavor
not to pollute our streams and lakes, which will no doubt be serving as
someone'sperhaps our ownsource of fresh water. Human
waste is a very dangerous contaminant of water resulting in many deadly
waterborne diseases including life-threatening diarrhea. We will discuss
proper waste disposal, including disposal of human waste, in a later chapter
of this web site.

Action Step 8: Planning For Your Water NeedsA. How Much Water? Open your Action Planner to the page where, in Action Steps 1 and 2, you made a list of the potential emergencies that concern you along with the scope and duration that each emergency is likely to involve. Consider now the longest duration that you considered likely for the events that cause you the most concern. Is it one week? One month? Six months? Now consider the number of people in your family and figure on needing at least one gallon (4 l) of water per person per day. Do you have other family members who might move in during an emergency or a neighbor who you might want to help? (Your neighbors will probably not be as prepared, and you must decide if you will be willing and able to help them.) Multiply the number of people by the number of days. That is the minimum number of gallons of water that you will need to get through the longest siege that you foresee. Write that number down in your Action Planner along with the words "water needed." If that sounds like a lot, remember that you should be able to replenish some of your water supply by collecting precipitation (rain or snow) or by scrounging from a lake or stream. But to do that you must have the necessary supplies, including purification and filtration equipment. If you will be able to collect additional water to help replenish your stored water, you might be wondering how much water you will actually need to store. I recommend that you store at least a 30 day supply. So multiply the number of people by 30 and that will give you the minimum number of gallons that you will need to put into storage. Write that number in your Action Planner along with the words "minimum storage." Remember that one gallon per person per day is the absolute minimum, not allowing for washing. Additional water could turn out to be greatly appreciated by everyone! If practical you should store two gallons per person per day. B. Water Checklists: In Action Step 6 you created a "Get" list and a "Do" list for water. Turn to that page now. In the "Get" column begin making a list of the items that you would like to acquire to meet your water needs, including collection materials, water treatment chemicals, water filters, etc. Continue on the back side of the page if necessary. In the right column under "Do" begin making a list of the things that you would like to do, or accomplish, to help you meet your goal for water storage. This list might include things like: Locate water sources around my home, Ask neighbors about local wells, Build a system to collect rainwater, etc. When you acquire an item or accomplish a task check it off your list. As you think of additional items add them to your lists. You do not have to run out and buy everything that you need right now. But start somewhere, even if it is only with one five gallon storage container. You can add to your stock as you are able, until you have reached your goal. Even though you do not have everything that you need right now, you will have made a start, and you will have a plan. It will only be a matter of time before you will reach your goals. Below is a sample "GET" list of items that you may want to acquire and a sample "DO" list of things that you might want to accomplish to help you prepare for your water needs during an emergency. Use these lists to help you formulate your own check lists:
