How to Collect Rainwater Safely in Wilderness?

Choosing the Right Container

When collecting rainwater in the wilderness, the container you choose is crucial. Opt for a sturdy, food-grade plastic container such as a 5-gallon bucket or a water jug with a screw-top lid. This will prevent contamination from the container itself and make it easier to transport and store the collected water. Avoid using tarps or other fabric materials that may be contaminated with chemicals or other substances.

Setting Up the Collection System

To set up a collection system, you’ll need to create a simple roof or overhang to direct the rainwater into your container. Use a tarp or a large piece of plastic sheeting to create a sloping surface that allows the water to flow freely into the container. Make sure the tarp is securely tied down to prevent it from blowing away in the wind. A good rule of thumb is to use a tarp with a collection area of at least 10 square feet to collect enough water for a day’s supply.

Storing and Purifying the Water

Once you’ve collected the rainwater, it’s essential to store it in a covered container to prevent re-contamination. Use a lid or a piece of plastic wrap to cover the container and prevent debris and insects from getting in. If you have access to water purification tablets or a portable filter, use them to purify the water before drinking it. If you don’t have these tools, you can also use boiling or solar disinfection (SODIS) to purify the water.
