For public water supply lines from tanks, what is the minimum distance required?

The minimum distance required for public water supply lines from tanks is 10 feet. This requirement is based on regulations that aim to ensure the safety and health of the public water supply. The reasoning behind this minimum distance is to prevent contamination of the water supply from potential sources of pollutants or pathogens that may be present in nearby tanks or structures. Maintaining a 10-foot distance creates a buffer zone, reducing the risk of backflow or contamination that could occur if the two were situated closer together.

This requirement is crucial for safeguarding the integrity of drinking water and ensuring compliance with health regulations. Factors that influence this distance include the type of materials used in the construction of the water lines, the nature of the tanks, and environmental considerations. By adhering to the 10-foot minimum distance, installers help to maintain a safe and reliable public water supply.
