Survivalist Tip: You must have plenty of containers to hold water; preferably made of steel, but firm plastic ones will suffice. Containers for long-term water storage come in a variety of sizes – starting at 5 gallons. If you plan to stay at home, I recommend much larger ones. You can keep these vessels in your garage or house or even in your apartment. Making certain the water stays fresh and drinkable is an obvious concern, so that’s why you also need a battery-powered water purification system. The ancient Mayans developed sophisticated water storage and purification methods without the benefit of electricity, computers, or utility companies. Therefore, it’s critical that you learn to gather, ration and treat your own water. These items will ensure a stable environment for you and your family. And, once things settle down, don’t just throw away these containers! Any good survivalist knows they’re for long-term use. Besides, you can store excess chocolate and gold bullion in them.
