Which term describes the proper distance between a sewage tank and a water supply for safety?

The term that describes the proper distance between a sewage tank and a water supply for safety is known as the "separation distance." This concept is crucial to ensure that contaminants from the sewage system do not enter the drinking water supply. Maintaining an appropriate separation distance helps prevent groundwater contamination and protects public health by ensuring that there is a safe buffer zone between sewage and potable water sources. Regulatory guidelines often specify minimum separation distances based on factors like soil type and local environmental conditions to further safeguard water quality.

While the other terms may seem relevant in discussions about safety and environmental management, they do not specifically define the required distance that must be maintained between sewage systems and water supplies.
