How far must a pressurized water supply line be from a sewage tank?

The regulation requiring a pressurized water supply line to be at least 10 feet from a sewage tank is based on health and safety standards aimed at preventing contamination of drinking water supplies. Maintaining this distance helps to reduce the risk of pathogens and pollutants from the sewage infiltrating the water supply, which could occur through leaks or backflow in the event of a malfunction.

This 10-foot minimum distance is recognized in various plumbing and construction codes, emphasizing the importance of keeping potable water systems separate from sewage systems to ensure safe and clean drinking water. Adhering to this standard contributes to the overall safety of public health by mitigating the potential for cross-contamination between water supply lines and sewage tanks.
