What is the horizontal separation required when installing collection systems lines in relation to water lines?

The recommended horizontal separation between wastewater collection systems and potable water lines is typically set at a minimum of 10 feet. This distance is crucial to ensure that any potential contamination from the wastewater system does not affect the drinking water supply. The separation helps to minimize the risk of pollutants or pathogens migrating from the collection system into the groundwater or the water supply lines, especially in the event of leaks, breaks, or other failures in the wastewater infrastructure.

Maintaining this separation also aligns with best practices and regulatory standards aimed at protecting public health and ensuring the safety of drinking water. The specified distance reflects both engineering practices and public health policies designed to prevent cross-contamination.
