Must the mantle be placed in all directions from the absorption trenches?

Explanation:
The mantle is the final soil cover used to restore grade over the absorption trenches. It doesn’t need to extend in every direction around the trenches. The purpose is to bring the surface back to its intended grade and protect the trench area, not to create a surrounding mantle radiating outward. Extending mantle beyond the trench area isn’t required and could even interfere with drainage and infiltration. So, placement in all directions is not necessary.
