What is the minimum distance of undisturbed soil required between the septic tank and the nearest drainage field?

• A. 3 Feet
• B. 4 Feet
• C. 5 Feet
• D. 6 Feet

Answer: (C)

The minimum distance of undisturbed soil required between the septic tank and the nearest drainage field is set at 5 feet to ensure adequate separation. This separation is crucial for several reasons, primarily relating to the effective functioning of the septic system and environmental protection. Having this buffer zone helps to prevent potential contamination of the drainage field from effluent that may overflow or leak from the septic tank, as soil acts as a natural filter. It ensures that any contaminants in the effluent have sufficient space to be treated by the soil's natural properties before they can potentially reach the drainage field. This distance also accounts for the movement of water and possible saturation levels in the surrounding soil, allowing for proper drainage and preventing the systems from interfering with one another. Maintaining regulations involving such distances is essential not only for public health but also for the longevity and efficiency of the sewage system as a whole. Understanding these requirements is critical for anyone involved in the design, installation, or maintenance of private sewage systems in Illinois.
