How far should a septic system be located from drinking water sources?

The recommended distance for a septic system to be located from drinking water sources is at least 50 feet to ensure the protection of the water supply. This distance is critical because it helps prevent potential contamination from pathogens, nitrates, and other pollutants that can leach from the septic system into the groundwater or surface water, which could then enter drinking water sources.

By maintaining a separation of at least 50 feet, the design aims to provide sufficient space for natural filtration and attenuation processes to reduce the concentration of harmful substances before they can reach the drinking water supply. This distance is in line with accepted best practices and regulatory guidelines for public health and environmental safety.
