What is the minimum allowable distance between a drinking water well and a septic system?

The minimum allowable distance between a drinking water well and a septic system is typically set at 50 feet to safeguard the drinking water supply. This distance is critical for preventing contamination of the well water from potential pollutants that may leach from the septic system.

Septic systems treat and dispose of wastewater, but they can also harbor bacteria, viruses, and other contaminants. Having a buffer zone helps ensure that any effluent that may seep into the ground does not reach the well, thereby protecting public health. Local regulations may vary based on environmental conditions, local geology, and other factors, but the 50-foot guideline is a common standard that balances practicality and safety for well installation near septic systems.

Understanding this distance is essential for plumbers and other professionals in the industry to ensure they adhere to safety regulations and provide safe water for their clients.
