Abstract: During installation and before a floor or foundation slab is put in place, a sewage ejector basin is set below grade and a basin extension of the present invention set in place around the basin. The basin extension of the present invention is rectangular in shape and comprises four basin extension sidewalls in communicable relation to each other at right angles; an opening within a top of the basin extension to allow access to the basin; and an opening within a bottom of the basin extension to accommodate a basin. An inlet pipe is routed underground and into the basin. A discharge pipe and a vent pipe are routed out of the basin and through a basin lid, oriented horizontally in relation to the floor, passed through a basin extension sidewall of the basin extension of the present invention, routed under the floor and toward a wall of a mechanical room.
