The top of the pump station has 8' of cover on them. Reinforced cover tanks will be needed unless a lift station is installed in the basement to allow for a shallow installation. s The inspection pipes on the tanks and mound are to be left at grade. The lateral cleanouts are to be left below grade in an enclosure. This is to protect them from lawn equipment.
