What is the mandated distance for public water supply lines from drip irrigation systems?

The mandated distance for public water supply lines from drip irrigation systems is 10 feet. This requirement is based on the need to prevent cross-contamination and ensure the safety of the drinking water supply. The 10-foot separation helps to minimize the risk of pollutants from the irrigation system being drawn back into the public water supply, particularly during conditions such as backflow events.

Maintaining this distance is crucial in safeguarding public health and ensuring that the water quality remains uncontaminated. Regulatory guidelines typically set these distances to reflect the industry standards for health and safety, emphasizing the importance of proper installation and maintenance practices in irrigation systems.
