Quick Answer
An emergency well should be at least 10-20 feet deep to ensure access to a reliable water source and minimize the risk of contamination from surface water or nearby water sources. This depth also allows for a reasonable amount of water to be stored in the well. Shallow wells may not provide a steady supply of water.
Choosing the Right Site
When selecting a location for an emergency well, it’s essential to consider factors such as soil composition, water table depth, and nearby water sources. A well-drained area with a mix of sand, silt, and clay is ideal, as it allows water to penetrate and accumulate. AVOID areas with high concentrations of salt, minerals, or other contaminants. A well placed at the top of a slope or near a natural water course may be subject to contamination or flooding.
Digging and Safety Precautions
To dig a safe and effective emergency well, start by excavating a shallow pit (about 3-4 feet deep) to check for water table depth and soil composition. Use a shovel, pickaxe, or backhoe to carefully dig the well, taking care not to collapse the sides or create a hazard. Install a sturdy well casing (at least 6 inches in diameter) to prevent collapse and protect the water from contamination. Ensure the well is at least 10 feet away from any potential sources of contamination, such as septic systems or animal enclosures.
