Edge depth requirement for mound cover states that edges must be at least how many inches deep?

Explanation:
Edge depth for mound cover is about ensuring the outer edge of the mound has enough soil to protect the system from weather, erosion, and surface loads. The minimum depth at the edge is six inches, which provides a stable, insulating shield over the components and helps prevent surface runoff or animals from exposing the riser or pipes. If the edge were shallower, you’d risk erosion, frost-related issues, or physical damage that could compromise the mound’s performance. Deeper edges, like eight or twelve inches, are not required by the standard but could offer additional protection; four inches would be insufficient to guard against these risks.
