A waste or storm water pumping station and system used to pump water from a lower elevation to a higher elevation during the process of moving or managing the water is disclosed herein. The pumping station has a wet well collection chamber with a sloped floor and an integral valve vault chamber cast within the pump station body, which results in increased storage capacity in the wet well chamber for pump station components. Additionally, the pumping station may be installed as a single unit of equal depth to eliminate differential settlement and multiple or uneven excavations.
