Abstract
A unitary concrete structure pumping station useful in pumping waste fluids and the like during the passing of such materials from one part of a gravity flow waste system to another. This concrete structure is simple to install and use and many of the problems associated with conventional pumping stations are alleviated. The structure is comprised of several parts that can be made pre-assembled at the factory or assembled in the field prior to installation. By being a unitary structure this pumping station is resistant to movements within the earth and therefore less likely to incur line breaks.
