Abstract: A sewage system comprising a network of sewage sumps that temporarily store sewage produced in a dwelling or other structure, each of said sumps preferably comprising a computer controller for operating a pump in the sump such that the sewage collected in the sump may be pumped out of the sump and into the collection system in a controlled manner to regulate the flow of sewage material in the system. The regulation of the sewage flow permits the efficient operation of a sewage treatment facility that receives sewage from the network of sewage sumps by insulating the facility from the peak burdens that would be placed on it at certain times of day in the absence of a system that regulates sewage flow into the system at the source of the sewage.

Abstract: An integrally molded plastic sump basin formed with two distinct portions including a constant depth, shallow dry well at the top defining a controls area that is isolated from a varying depth wet well below, said wet well defining a pump chamber. All electronic controls, level sensor controls and valve extension control are situated in the non-hazardous dry well while pump(s) and associated piping are contained within the potentially hazardous wet well part of the basin. The sump basin may be formed with a drop inlet opening for sewage entry that enhances installation flexibility and provides more efficient processing of sewage entering the basin.

Abstract: A plastic pipe joint between two dissimilar plastics, one being a non-glueable olefin or rubber and the other a glueable or solvent-weldable plastic. The joint consists of a glueable, plastic ferrule compression fitted over the end of an olefinic or other non-glueable pipe by means of an internally expanded metal insert inside the olefinic pipe. A method for employing the instrumentalities of the invention in a pipe joint is also described.
