Rainwater and snowmelt are the primary sources of all drinking water on the planet. Rainwater harvesting is the practice of collecting the water produced during rainfall events before it has a chance to run off into a river or stream or soak into the ground and become groundwater. Rainwater harvesting can be classified into two broad categories: land-based and roof-based. Land-based rainwater harvesting occurs when rainwater runoff from the land is collected in ponds and small reservoirs before it has a chance to reach a river or stream. Roof-based harvesting, on the other hand, involves collecting the rainwater that falls on a roof before the water even reaches the ground. Although roof-based systems generally produce water with lower levels of chemical and biological contaminants, the water produced by both systems is subject to contamination and must be properly treated before it can be used. The level of treatment you need to provide depends, to a great extent, on whether you will be using the water for potable purposes (such as drinking, food preparation, bathing, and dish- or hand-washing) or for nonpotable purposes (such as toilet flushing, clothes washing, and watering). Obviously, rainwater that is intended for potable purposes must receive a higher level of treatment than rainwater that is intended for irrigation purposes.
Government does not set minimum treatment requirements for rainwater that will be used as a drinking water source for a single household nor do they regulate nonpotable uses of rainwater.
If you have access to a public water system, we encourage you to utilize your rainwater
collection system for nonpotable use only. This approach will:
• Reduce your construction, treatment, and operational costs, because less
treatment is required for nonpotable uses than for potable uses.
• Lower your monthly water bill because you will need to buy less of the public
water system’s drinking water for nonpotable use.
• Conserve the natural resources being developed and utilized by your public
What Kinds of Contaminants Can Be Found in Rainwater?
Rainwater and snowfall are the ultimate sources of all drinking water on the planet. Rainwater and melted snow runs off the land and collects in lakes and rivers. They also seep through the ground and recharge the aquifers that supply drinking water wells. Regardless of where you currently obtain your drinking water, it originally fell from the sky.
The water in a raindrop is one of the cleanest sources of water available. Rainwater can absorb gases such as carbon dioxide, oxygen, nitrogen dioxide, and sulfur dioxide from the atmosphere. It can also capture soot and other microscopic particulates as it falls through the sky. Nevertheless, rainwater is almost 100% pure water before it reaches the ground.
Pure water is considered the universal solvent; it can absorb or dissolve contaminants from almost anything it comes into contact with. That is why it is especially important to design and operate your system so that the rainwater picks up as few contaminants as possible before you consume it.
We use the term “debris” to describe any contaminant that you can see. Debris includes leaves and twigs, dust and dirt, bird and animal droppings, insects, and other visible material. Although debris obviously reduces the aesthetic quality of the water, it can also pose unseen chemical and biological health threats. For example, leaves and dust can contain unseen chemical contaminants such as herbicides and pesticides. Similarly, bird and animal droppings can contain microscopic parasites, bacteria, and viruses.
Although rainwater can be contaminated by absorbing airborne chemicals, most of the chemicals present in harvested rainwater are introduced during collection, treatment, and distribution. By properly designing and operating your rainwater harvesting system, you can minimize your exposure to a variety of chemical contaminants that include organic chemicals, such as volatile and synthetic organics, and inorganic chemicals, such as minerals and metals.
Volatile Organic Chemicals
Volatile organic chemicals (VOCs) can be introduced when rainwater comes into contact with
materials containing refined organic products. These VOC sources include plastics, glues, and
solvents, as well as gasoline, greases, and oils. Most VOC contamination at rainwater systems
occurs because the materials used to construct the system were not manufactured specifically
for drinking water applications; these materials may not meet the standards set for potable
water products and may release undesirable levels of VOCs into the water. Although most VOC
contamination results from improper construction practices, VOC contamination can also occur when raindrops fall through an atmosphere containing gasoline or solvent vapors.

Synthetic Organic Chemicals
Synthetic organic chemicals (SOCs) are chemicals that are typically found in pesticides,
herbicides, and similar man-made products. Since SOCs are not very volatile, these contaminants are usually introduced when debris such as dust and leaves are allowed to enter the system. However, SOC contamination can also be introduced if you install your rainwater collection and storage system in an area where aerial herbicide or pesticide application occurs. Regardless of how the chemical reaches the rainwater system, SOC contamination is usually the result of environmental exposure rather than poor construction practices.
Minerals are inorganic materials found naturally in the environment. Most minerals are
inorganic salts (such as calcium carbonate, sodium bicarbonate, magnesium sulfate, and sodium chloride) that affect the flavor of the water but generally do not pose an actual health threat. The most significant exception to this general rule of thumb is asbestos, which is a family of fibrous silica salts used to manufacture a variety of products. Under certain conditions, some of these products can release a form of asbestos that can pose a long-term health threat if ingested or inhaled. Minerals, especially calcium and magnesium salts, are what gives water its hardness. Rainwater contains virtually no minerals before it is harvested and so it is a very soft water. It is also slightly acidic, with a pH around 5.6, due to the carbon, nitrogen, and sulfur dioxides it absorbs from the atmosphere. Because it takes time for rainwater to absorb minerals, most of the minerals present in harvested rainwater will have been leached from materials used to construct the system rather than from environmental sources.
Metals include lead, arsenic, copper, iron, and manganese. Some metals, such as lead and arsenic, can pose a long-term health threat if they are present in high enough concentrations. Other metals, such as iron and manganese, can affect the appearance and taste of the water but pose no health threat. It takes time for metal to dissolve in rainwater. Therefore, this type of contaminant is usually present only after metallic materials such as lead solder, iron and copper pipe, and brass fittings have been exposed to rainwater for several hours or longer.
Rainwater seldom contains any type of microbiological contaminant until it is harvested and stored. The water in a raindrop is extremely pure, but it is virtually impossible to maintain that level of purity during the collection, treatment, and distribution processes. Rainwater can be contaminated by two major categories of microbiological agents: those that cause disease and those that do not. Microbiological contaminants that can cause a disease or infection are called pathogenic, while those that do not are called nonpathogenic. Nonpathogenic organisms can be present in high numbers regardless of where your home is located.
These nonpathogenic microbes include many kinds of protozoa, algae, bacteria, and viruses.
Although they do not cause illness, nonpathogens often reduce the aesthetic quality of the water and can interfere with the operation of the rainwater harvesting and treatment facilities, increasing

operational and maintenance requirements. For example, high concentrations of algae can make the water slimy, plugging the filters used to treat the water, or fungi and bacteria can colonize in the water lines in your home. Pathogenic organisms are not normally found in rainwater. However, they can be present if the
rainwater collection or storage facilities have been contaminated by fecal material such as animal or bird droppings. Pathogenic microbes pose a greater health threat to rainwater users than most chemical contaminants, for a number of reasons, including:
• Pathogens can cause disease after a single exposure, while most chemical contaminants may
require months or even years of exposure before causing a health effect.
• Pathogens do not affect the taste, smell, or appearance of the water. Many chemical
contaminants, on the other hand, make the water taste, smell, or look different, especially if the chemicals are present at levels that would pose a short-term risk.
• Pathogen levels can rise very quickly, while chemical levels tend to remain fairly constant.
Consequently, it is relatively easy (though somewhat costly) to periodically test for chemical
contaminants, while it is both difficult and costly to continuously test for most pathogens.
• A disease caused by pathogens can usually be passed from person to person, while the health
effects caused by chemicals affect only those that actually consume the contaminated water.
• Waterborne illnesses caused by pathogens can be a serious health risk for the elderly, infants, chemotherapy patients, and other individuals with a delicate or weakened immune system. Pathogenic microbiological contaminants include certain types of protozoan parasites, bacteria, and viruses. The infectivity rates (the number of microbes required to cause a disease) and the virulence (the severity of the disease) vary, depending on the type of pathogen present and the immune system of the person that is exposed. Some pathogens can cause an illness if a person with a weakened immune system is exposed to just a few organisms. Some of the pathogens that can be introduced through improperly designed and operated rainwater systems are shown in Table 1.1.
|Type of Pathogen||Organism||Source|
|Parasite||Giardia lamblia||cats and wild animals|
|Parasite||Cryptosporidium parvum||cats, birds, rodents, and reptiles|
|Parasite||Toxoplasma gondii||cats, birds, and rodents|
|Bacteria||Campylobacter spp.||birds and rats|
|Bacteria||Salmonella spp .||cats, birds, rodents, and reptiles|
|Bacteria||Escherichia coli||birds and mammals|
Using Ceramic High Efficiency Filters can remove 99.99% of pathogenic debris from water sources for usable potable water. Setting up a primary storage tank for collection and transferring water via gravity or pumping station to a potable storage tank is the preferred method of insuring water is clean, free from pathogens.
Shelter is an important aspect of every outdoor venture or survival situation. Your first layer of shelter is the clothing on your back, this provides you just enough to stay warm and dry for short periods of time. Your second layer of shelter is a stationary structure whether it is a small tent or a full blown log cabin. Knowing how to either aquire or make shelter for you and your family in an emergency is an important skill.
Take shelter in your vehicle if travelling to your family designated meet zone or safe zone. If SHTF it’s best to stay away from urban areas and park or set camp off main roads away from view. Back country roads and crop fields may provide the seclusion needed to avoid possible unwanted human contact. If you’re on foot or traveling with a small group, try to set camp near a secluded water source.
2: Water is Life.
You will need water. The rule is 1 gallon per person per day in warm climates. You and your family can survive on less, but it’s always best to have reserves. You have many options once you find a source of water to treat the water to insure it’s safety and avoid health concerns. If you know the water source is clean such as a well or city storage then it would be safe to assume it is drinkable. If your only option is open water sources, you need to treat the water as unclean until treated.
Safe water treatment options.
Boil water after you have filtered out the large debri. Boiling water will kill any bacteria or protozoa and male the water safer to drink, but will not remove heavy metals or smells. After boiling let the water stand before consuming.
Add 4 drops of bleach per gallon of water and let stand for half an hour stirring occasionally. Then consume. This also will kill bacteria and viruses but not address heavy metals.
Mechanical filtering and carbon filtering will remove all bacteria and viruses. Mechanically treated water can also remove heavy metals, smells and radiation. See SHTFandGO.COM for their line of mechanical filtering systems.
A blade, machete, hatchet, axe or some other cutting tool is the most important tool to the Bushcrafter. It is as important as the sword to knight. A good Bushcraft blade is sturdy and light and is made from the highest quality materials with the tang running the full length of the knife. With appropriate use, the Bushcrafter can use this blade to give or take life. A Survival Knife is just that, survival. One can clean animals for consumption and make tools for hunting and trapping.
The ability to make fire under almost any condition is essential part of Bushcraft survival. Without Fire modern man is nothing more than a wild animal. There are many techniques to building a fire; a fire drill, smoldering plants and trees, sunlight, striking rock that contains iron such as flint, and of course matches, lighters, and modern fire starting tools. Firecraft in the ability to create, control, and use fire to aid in one’s survival. Another critical skill in Bushcraft is the ability to transport fire, usually by carrying a burning coal around in some type of dry sage grass to keep it smoldering.
5: Rope, Cordage and Knots
The ability to tie or join two or more pieces of natural or man made material is a vital skill for survival. By joining two or more pieces together, you not only increase the strength of the material but also the usability as shelter, a raft, a weapon or a sled. Fishing and trapping are important survival skills and without the ability to tie knots and obtain or create cordage.
6: Hunting and Trapping
Protien and fats are important to sustain nutrition. Hunting and trapping is the pursuit of animals and fish for food. A mastery of many elements in Bushcraft including tracking and ropecraft lead to the ability to hunt for food by use of traps, nets and snares or weapons that stab and cut. The ability to capture and kill animals for food is a essential skill necessary to live in the wild. Once food has be caught and or procured, food storage and treatment is also a skill necessary to store enough food to last harsh winters.
Tracking animals and humans is an important part of Bushcraft survival. Tracks made by humans and animals on the ground, when read correctly, show a pattern of the habits of the animal or human. Once you establish this pattern, you will have the ability to continuously and carefully observe the animal’s movements and patterns. It is important to recognize that animals you find in the forest are as much creatures of habit as human beings. A particular animal you are stalking will follow the same path to and from water each day or to and from a food source. It will hunt and forage in the same area and only leave when it is driven out by an outside force, predator, fire, flood or drought. This pattern forming characteristic of all animals makes it possible for the experienced bushcrafter to predict the animal’s movements, and so he selects the sites for his traps, snares or ambush.
If you are just travelling from an emergency hot spot to your safe zone or to meet family, emergency food stores or food rations will be you best saurce of nutrition while you’re on the go. Once you are settled at a camp or in wild yoi’ll need a source of food.
Have you ever looked at a wild plant or bush, and wondered if you could eat it? For the Bushcrafter, foraging is very important element to survival. All hunters and fisherman know that if it was easy, they would not call it hunting and fishing, they would call it catching. Being able to identify and eat plants without getting sick can make the difference between surviving and not surviving.
