According to the standards, how far should public water supply lines be from lined evapotranspiration beds to ensure safety?

The correct distance for public water supply lines from lined evapotranspiration beds is 10 feet. This standard is established to minimize the risk of contamination of the water supply. Evapotranspiration beds are used for the disposal of wastewater, and ensuring a safe distance helps prevent potential leaching or migration of contaminants into the public water supply system.

The 10-foot buffer zone is based on hydraulic and environmental factors that consider both the properties of the soil and the nature of the wastewater involved. This distance allows for adequate protection and ensures that any potential contaminants are less likely to affect the public water supply, thereby safeguarding public health.

Other distances, either shorter or longer, do not provide the same level of assurance against possible contamination risks as established by industry standards. As such, the 10-foot separation is a critical measure in maintaining safe and effective public health regulations.
