Why have a 50 gallon drum in your basement that you can’t carry, that is under 8 feet of flood water, or buried under rubble that once was your home? Instead, you can keep a small, compact Geigerrig emergency water system in your car and/or home that you can throw over your shoulder and walk away from the danger.
The system sprays so that you can share the water and use the water to clean wounds, hydrate and help others. The in-line filter and water purification tablets allow you to make use of water you find along the way. Just grab the survival rig and go!
