The prefab lift station has a well casing including mechanical equipment therein and a horizontal upper rim. A foundation slab is mounted to the horizontal upper rim and covers the well casing. A building is mounted to the foundation slab. The foundation slab and the building are mounted offset from a center of the horizontal upper rim, to accommodate a hatch through the foundation slab in front of the building giving unrestricted access inside the well casing. A portion of the slab and a portion of the building are overhanging outside the horizontal upper rim. The foundation slab has a weightless volume incorporated therein for shifting a center of gravity of the foundation slab and the building to a region inside the horizontal upper rim of the well casing. The foundation slab and the instrument building are self-balanced on the well casing. |
