How wide should the top of an embankment be at minimum?

The minimum width of the top of an embankment should be at least 2 feet. This width is crucial for several reasons related to the stability and safety of the embankment. A wider top provides a better platform for access during maintenance and inspection processes. It also aids in distributing the load more evenly across the supporting soil structure, reducing the risk of erosion or failure.

In the context of septic systems, the width of the embankment can influence water drainage and the overall effectiveness of the system. If the embankment is not wide enough, it may compromise the intended function and stability, leading to potential issues with the septic system over time.

Wider embankments, beyond the minimum requirement, could improve accessibility and support larger equipment during maintenance, but the established 2-foot width is the minimum necessary to ensure safety and functionality. Adhering to this standard is fundamental to maintaining the integrity of septic installations.
