Quick Answer
Water storage tanks are generally a better option for families due to their larger capacity, easier accessibility, and reduced risk of contamination.
Choosing the Right Tank Size
When selecting a water storage tank for your family, consider the minimum amount of water needed for a 3-day emergency supply. The American Red Cross recommends at least 1 gallon per person per day, which translates to 21 gallons per person for a 3-day supply. For a family of four, a 100-gallon tank would provide the recommended amount of water.
Tank Materials and Durability
Consider the material of your water storage tank, as it will affect its durability and resistance to corrosion. Polyethylene tanks are a popular choice due to their affordability and resistance to chemicals and UV light. Look for tanks with a Food and Drug Administration (FDA) certification, which ensures compliance with safe water storage standards.
Installing and Maintaining Your Tank
Proper installation and maintenance of your water storage tank are crucial to preventing contamination. Ensure the tank is placed on a level surface and the lid is securely fastened. Check the tank regularly for signs of damage, leaks, or contamination. Consider installing a float valve to automatically shut off the water supply when the tank is full, and a pressure relief valve to prevent over-pressurization.
