What is the minimum distance between a sewage tank and a storm water structure?

The minimum distance of 25 feet between a sewage tank and a storm water structure is established to ensure proper function and minimize the risk of contamination. This distance is critical for several reasons related to public health and environmental protection.

Firstly, it helps to prevent potential leachate from the sewage tank from entering the storm water system, which could lead to the contamination of surface water bodies. Contamination could occur from overflow or infiltration during heavy rainfall, where storm water collects runoff that may carry pollutants.

Additionally, maintaining this distance allows for adequate space for maintenance and repair operations. It is essential for service vehicles to access the sewage tank without obstruction, ensuring that inspections and pumps can be conducted efficiently.

The regulations surrounding these distances are developed based on best practices from public health and environmental management disciplines, emphasizing the importance of preventing cross-contamination between sanitary waste systems and storm water drainage systems.
