The tank has vertical walls joined to a horizontal bottom with a diagonal wall bridging between an intermediate portion of one of the vertical walls and the bottom. The diagonal wall has an access opening formed therein, and it cooperates with the one vertical wall and the bottom to form a sheltering recess, in the tank, for pumping station components. The pumping station has the relevant components emplaced in the tank, and sewage water admitting and discharging facility, with a submersible pump and water-handling piping. Station components, and portions thereof, are sheltered in the recess of the tank, to accommodate an optimum water flow in the tank, and to minimize an entanglement of solid objects with the components.
