How far must lined evapotranspiration beds be from streams, ponds, lakes, or rivers?

The correct distance requirement for lined evapotranspiration beds from streams, ponds, lakes, or rivers is 50 feet. This spacing is essential to prevent potential contamination of water bodies from wastewater and to ensure proper separation for environmental and health protection. This distance helps to mitigate the impacts of any seepage or overflow from the evapotranspiration beds, allowing for adequate buffer zones to maintain water quality and safeguard aquatic ecosystems. Additionally, the regulation reflects best practices in wastewater management by promoting the protection of surface water sources.

The stipulation of 50 feet might stem from considerations of groundwater flow and surface runoff patterns, ensuring enough distance to minimize the risk of pollutants reaching these natural water bodies.
