ABSTRACT:
Conventional sewage ejector systems include a standpipe into which effluent may drain and seep into the surrounding soil thus causing pollution problems. This device includes a sewage ejector nozzle connected to a discharge pipe and forming part of said pipe. The nozzle and pipe are detachably secured within a sealed standpipe so that when the system is not working, the effluent within the discharge pipe drains back into the standpipe and is contained thereby until the next discharge cycle commences at which time it is picked up by the effluent passing through the jet which includes a venturi restriction. When the effluent in the standpipe is all ejected, air is picked up and entrained in the effluent stream thus aerating the discharge effluent.
