Whether you are in the wilderness, facing a natural disaster, or preparing for uncertain times, understanding water sourcing and purification techniques is crucial for maintaining hydration and preventing waterborne illnesses. In this article, we will explore effective methods for sourcing and purifying water to ensure access to safe drinking water in survival situations.

Water Sourcing Techniques

Natural Sources:

• Rivers, Streams, and Lakes: When it comes to sourcing water in the wilderness, rivers, streams, and lakes are often readily available. However, it’s essential to learn how to identify and locate these natural water sources correctly. Understanding the terrain and topography can help you identify potential watercourses. Look for signs of flowing water, such as the sound of running water or the presence of vegetation along the banks. When assessing the safety and suitability of these water sources, consider potential contamination risks from upstream industrial or agricultural activities. It’s advisable to purify water obtained from rivers, streams, or lakes before consuming it.
• Springs and Seeps: Springs and seeps are valuable water sources that can often provide clean and reliable water. A spring is a natural water source that emerges from the ground, usually from an underground aquifer. Seeps refer to areas where water slowly seeps out of the ground, forming small pools or damp areas. These sources are generally cleaner than rivers or lakes since the water has been filtered through the ground. When locating springs or seeps, keep an eye out for areas with lush vegetation or damp ground. Collect water from these sources using a container or by constructing a simple filtration system to remove any debris before consumption.

Rainwater Collection:

Rain water collection is a valuable method for sourcing water, especially in areas with regular rainfall. Setting up rain barrels or using a tarp to collect rainwater allows you to harness this renewable resource and create a potentially safe water source. Here’s a more detailed exploration of these methods:

Rain Barrels: Rain barrels are large containers specifically designed to collect and store rainwater. Follow these steps to set up a rain barrel system:

1. Select a Suitable Barrel: Choose a food-grade plastic or recycled barrel with a tight-fitting lid to prevent debris and contaminants from entering the water.
2. Positioning: Place the rain barrel under a downspout or an area where rainwater runoff occurs. Ensure it is stable and elevated to allow easy access to the spigot at the bottom.
3. Gutter and Downspout Diversion: Direct the downspout into the barrel using a diverter kit or by cutting the downspout and attaching a flexible extension that leads to the barrel.
4. Screen and Filter: Install a fine mesh screen or filter at the entry point to the barrel to prevent leaves, insects, and other debris from entering.
5. Overflow System: Include an overflow system, such as a diverter or hose, to redirect excess water when the barrel is full, preventing overflow and potential water damage.

Tarp Collection: In situations where rain barrels are not available, using a tarp or plastic sheet can be an effective method to collect rainwater. Follow these steps for tarp collection:

1. Select a Suitable Tarp: Choose a large, durable, and preferably waterproof tarp or plastic sheet.
2. Site Selection: Identify an open area where rainwater can collect without obstruction, such as a clearing or an open space away from contaminants.
3. Anchoring and Inclination: Securely anchor the tarp using stakes or rocks at the corners and along the edges. Ensure the tarp is slightly inclined to allow rainwater to flow towards a central collection point.
4. Collection Container: Position a clean and sanitized container, such as a bucket or storage container, beneath the lowest point of the tarp where water accumulates.
5. Filtration: Filter the collected water using a cloth or a fine mesh screen to remove any debris or impurities before consumption or storage.

Additional Methods for Rainwater Collection:

Roof Runoff: Directing roof runoff into rain barrels or storage containers is an effective method. Install gutters and downspouts to channel rainwater into the containers. Consider using a first-flush diverter system to divert the initial rainfall, which may contain more debris, away from the storage container.

Rainwater Harvesting Systems: For more extensive rainwater collection, consider implementing a rainwater harvesting system that incorporates multiple collection points, underground storage tanks, and a filtration system. These systems can be complex and require professional installation but offer long-term water sustainability.

Remember to regularly clean and maintain rain barrels or collection tarps to prevent the growth of algae or the accumulation of sediment. Additionally, use stored rainwater within a reasonable timeframe and treat it appropriately before consumption, especially if the water will be stored for an extended period. By utilizing rain barrels and tarps for rainwater collection, you can ensure a renewable and potentially safe water source, providing you with a valuable supply of water for various purposes in survival situations.

Groundwater:

Wells and Digging Techniques: Accessing groundwater through wells is a more involved process but can provide a reliable and relatively safe water source. Digging a well requires careful planning and the use of appropriate equipment. It’s crucial to identify the ideal location, considering factors such as soil composition, proximity to potential contamination sources, and accessibility. Wells can be dug manually using shovels or with the assistance of mechanical tools like augers or well drilling rigs. Ensure you follow safety guidelines while digging, such as securing the well walls to prevent cave-ins. Test the water quality before consuming water from a newly dug well to ensure it is safe for drinking.

By understanding these water sourcing techniques in more detail, you can confidently locate and collect water from natural sources, harness rainwater, and tap into groundwater reserves. Remember to prioritize water purification and assess the safety of the water before consuming it to minimize the risk of waterborne illnesses.

Water Purification Methods

Boiling: Boiling water is one of the simplest and most effective methods to purify water in a survival situation. Here are some key details on this purification method:

1. Bring water to a rolling boil: Heat the water until it reaches a vigorous, rolling boil. This ensures that harmful microorganisms, such as bacteria, viruses, and parasites, are killed.
2. Maintain a boil for at least one minute: Once the water reaches a rolling boil, continue boiling it for at least one minute. In higher altitudes where water boils at a lower temperature, it is recommended to boil water for three to five minutes.
3. Allow the water to cool before consumption: After boiling, let the water cool naturally before drinking or storing it in clean, covered containers.

Filtration: Filtration is an effective method for removing physical impurities and some microbial contaminants from water. Here’s more information on two types of filtration methods:

1. Portable Water Filters: Portable water filters are compact devices that use physical barriers, such as ceramic, activated carbon, or hollow fiber membranes, to trap and remove contaminants. These filters typically come with different pore sizes, which determine the size of particles and microorganisms they can effectively filter out. Follow the manufacturer’s instructions for proper use and maintenance of portable water filters.
2. Improvised Filters: In survival situations, you can create improvised filters using readily available materials. One method involves constructing a filtration system using layers of coarse gravel, fine sand, activated charcoal, and cloth. This setup helps remove larger debris, sediment, and some microorganisms. Remember that improvised filters may not be as effective as commercial filters and should be used as a temporary solution until better filtration options are available.

Chemical Treatment: Chemical treatments can effectively disinfect water and kill a broad range of microorganisms. Here are two common chemical treatment methods:

1. Chlorination: Chlorine-based products, such as chlorine bleach or chlorine tablets, can be used to treat water and make it safe for consumption. Follow specific instructions provided by the manufacturer or trusted sources for the correct amount of chlorine to add based on the volume of water being treated. Allow the water to stand for about 30 minutes after adding chlorine before using or consuming it.
2. Iodine Treatment: Iodine tablets or liquid iodine can also be used to disinfect water. Similar to chlorination, follow the instructions on the packaging for the appropriate dosage based on the volume of water. Let the iodine-treated water stand for the recommended contact time before using or drinking it. Note that iodine treatment may not be suitable for pregnant women, individuals with thyroid conditions, or those with iodine allergies.

Solar Disinfection (SODIS): Solar Disinfection, commonly known as SODIS, is a low-cost method that utilizes sunlight to kill harmful microorganisms. Here’s an overview of the SODIS method:

1. Fill clear plastic bottles: Fill clear PET (polyethylene terephthalate) bottles with water, leaving some air space at the top.
2. Place bottles in direct sunlight: Set the bottles in a sunny area, preferably on a reflective surface, such as a metal sheet or aluminum foil, to enhance the solar radiation.
3. Expose to sunlight for 6 hours (or longer): Leave the bottles undisturbed in the sunlight for at least six hours on a clear day. Cloudy weather may require longer exposure times.
5. Use caution with turbid water: SODIS is most effective with clear water. If the water is turbid or cloudy, it should be filtered or settled before using the SODIS method.

Remember that while these purification methods can significantly reduce the risk of waterborne illnesses, they do not eliminate chemical contaminants. If you suspect chemical contamination, such as from industrial pollutants or toxic substances, additional treatment or finding an alternative water source is advisable.
