What is the required minimum setback for down-gradient drains from the edge of a reserve drain field?

The required minimum setback for down-gradient drains from the edge of a reserve drain field is crucial for ensuring that the wastewater flow does not contaminate any nearby water sources or interfere with the functionality of the septic system. A setback of 30 feet provides a sufficient buffer that helps protect groundwater and maintain the overall health of the surrounding environment.

Having this distance allows for the natural absorption and filtration processes to occur effectively, ensuring that any potential contaminants are adequately treated before reaching nearby surface or groundwater. This setback is particularly important in maintaining the integrity of the septic system and preventing any public health risks associated with contaminated water. The specified distance typically aligns with regulatory standards aimed at safeguarding both human health and environmental quality.
