ABSTRACT:
A sewage pumping or lift station is mounted on the upper edge of a standard concrete wet well. A vertical partition divides the station into a machinery chamber and an access chamber that are hermetically isolated from each other. The floor of the machinery chamber is imperforate except for a hole through which a sewage inlet pipe passes and that hole is sealed by weldments attaching the inlet pipe to the floor; this hermetically isolates the machinery chamber from the sewer gases in the wet well. Any other components which must communicate with the wet well pass through sealed holes in the vertical partition.
