摘要

A wastewater sump assembly for receiving and disposing of undesired fluid and, in some cases, solid waste is disclosed. A sump basin formed from a base, an upstanding wall and a top which are all defined from a single, integral, monolithic material may be employed. The top of the monolithic basin includes a pump access aperture sized to allow passage of a submersible pump. Pipe stubs are provided in a recessed area of the top to allow for easy connection to outlet and vent piping. Interchangeable switches of differing types, e.g. a diaphragm switch and a float switch can be utilized with the sump basin. Certain switch subassemblies include a handle to facilitate easy removal. The handle may also be utilized to hold a cord seal in place atop the sump. A diaphragm switch in accordance with the present disclosure may be positioned externally of the sump.
