Quick Answer
STORING WATER UNDERGROUND HAS SEVERAL ADVANTAGES OVER ABOVE-GROUND STORAGE, INCLUDING PROTECTION FROM EXTREME TEMPERATURES AND CHEMICAL CONTAMINATION, AS WELL AS EASY ACCESS AND AESTHETIC APPEAL. IT ALSO REDUCES THE RISK OF WATER EVAPORATION AND CONTAMINATION FROM INSECTS AND ANIMALS. THIS METHOD IS ESPECIALLY SUITABLE FOR LONG-TERM WATER STORAGE.
Underground Water Storage Benefits
Underground water storage is ideal for preppers who need a reliable and long-lasting water supply. When stored underground, water is protected from extreme temperatures, which can cause it to degrade and become unusable. In areas with frequent wildfires or heatwaves, underground storage can ensure a consistent water supply even when the surface is contaminated. For example, a typical 1,000-gallon water tank can lose 1-2 gallons of water per day due to evaporation when stored above ground.
Choosing the Right Underground Storage
When selecting an underground storage location, look for sites with stable and impermeable soil, such as clay or concrete. The ideal location should also be away from potential water sources, including nearby rivers, lakes, or aquifers, to prevent contamination. In areas with a high water table, it’s essential to choose a location with a sufficient depth to prevent water saturation. A general rule of thumb is to store water at least 10-15 feet below the surface to minimize the risk of contamination.
Installation and Maintenance
Installing an underground water storage system requires proper planning and execution. First, drill a well or excavate a hole to the desired depth, then line it with a durable and impermeable material, such as PVC or concrete. Next, install a secure lid or cap to prevent accidental access or contamination. Regularly inspect the storage site for signs of damage, leaks, or contamination, and perform maintenance tasks as needed to ensure the water remains safe and usable.
