Quick Answer
While rainwater can be a reliable source of drinking water in the wilderness, it's essential to properly collect, store, and treat it to prevent contamination and waterborne illnesses.
Collecting Rainwater
Collecting rainwater is simple and efficient. Look for a waterproof surface, such as a plastic sheet or a tarp, to direct rainwater into a collection container. Place the collection container under a tree with a wide canopy or create a makeshift rainwater collection system using a plastic sheet, sticks, and rocks. Aim to collect at least 2 gallons of water per person per day.
Storing Rainwater
Proper storage is crucial to prevent contamination and bacterial growth. Use a clean, food-grade container with a tight-fitting lid to store the collected rainwater. Label the container and store it in a shaded area, away from direct sunlight and potential sources of contamination. Keep the container covered and protected from dust, leaves, and other debris.
Purifying Rainwater
Rainwater may contain small amounts of particulate matter, bacteria, and viruses, making it necessary to purify it before consumption. Use a water filter or purification tablets to remove contaminants and make the water safe to drink. Aim to purify at least 1 gallon of water per person per day, and re-purify any stored water every 24 hours to maintain its safety.
