What is the required distance between public water supply lines and sewer pipes with watertight joints?

The required distance between public water supply lines and sewer pipes with watertight joints is 10 feet. This regulation is designed to prevent contamination of drinking water supplies due to potential leakage or failure of sewer pipes. Maintaining this distance provides a safety buffer that minimizes the risk of cross-contamination between the potable water system and the waste management system.

In the context of public health and safety, adhering to these specifications is crucial to ensure that water supplies remain clean and uncontaminated, thereby preventing waterborne diseases and other health hazards associated with contaminated water. Proper separation distances are an essential aspect of water supply management and are critical in maintaining the integrity of public health systems.
