What is the necessary setback for a septic tank from a pressurized water line?

The necessary setback for a septic tank from a pressurized water line is 10 feet. This regulation is in place to prevent potential contamination of the potable water supply. The proximity of a septic tank to a pressurized line poses a risk; if the septic system were to develop a failure or leak, harmful substances could potentially migrate through the soil and reach the water line. By maintaining a minimum distance of 10 feet, the likelihood of this contamination is greatly reduced, ensuring the safety of the drinking water supply and adhering to health standards and regulations.

The other distances listed, while they may have their applications in different contexts or for different types of systems, do not provide the safety buffer that the 10-foot requirement ensures in this specific scenario. This makes the 10-foot setback the appropriate and correct standard in Georgia for the separation of septic systems from pressurized water lines.
