Which of the following distances is required for a sewage tank from the edge of the drain field?

The requirement for the distance of a sewage tank from the edge of the drain field is established to ensure proper functioning and maintenance of the septic system. A distance of 50 feet helps prevent the potential contamination of the drain field from effluent leakage or overflow originating from the sewage tank. This separation distance is crucial to minimize the risks associated with effluent reaching areas where water is absorbed or where it could contaminate groundwater. Proper spacing is also necessary to promote the unhindered operation of both the sewage tank and the drain field, allowing for adequate space for maintenance, repairs, and inspections while contributing to the overall health and safety standards of the septic system.
