A self-contained, indoor wastewater disposal system for collecting, grinding, and pumping wastewater is readily installed within a building such as in the basement thereof by connecting to a wastewater feed pipe, to a wastewater discharge pipe, and to an electrical power supply such as a standard 120 volt or 220 volt electrical outlet. The system generally includes a tank, a grinder pump, and an alarm unit for indicating a problem with the operation of the system. The alarm unit is desirably operable to indicate loss of electrical power to the grinder pump, indicate an overflow water level in the tank, and/or indicate adegradation of performance of the grinder pump. The tank may be configured for receiving the wastewater feed pipe from the building at either of two orientations which are disposed ninety-degrees from each other so that the system may be easily and closely positioned adjacent to a wall of the building and so that the connection of the wastewater feed pipe to the tank is obscured from view.

Indoor wastewater disposal system and tank therefor

Home wastewater disposal unit

A grinder pump station is capable of having its height adjusted in the field during installation, and includes a substantially cylindrical inner wall having an inner surface and an outer surface. The inner surface of the inner wall defines a cavity for insertion and mounting of a grinder pump therein. In addition to the substantially cylindrical inner wall, there is a substantially cylindrical outer wall having an inner surface and outer surface, wherein the outer wall has a diameter greater than the inner wall. For increasing the structural integrity of the grinder pump station, a plurality of rigid members extend between the substantially cylindrical inner wall and the substantially cylindrical outer wall, each of the plurality of rigid members being affixed to the inner wall and each of the plurality of rigid members being engaged to the inner surface of the outer wall. A base disposed is located adjacent to a lower portion of the inner and outer walls. The grinder pump station may include a plurality of rigid members that define a central corrugated wall. The central corrugated wall may further comprise a plurality of alternating crests and troughs, wherein each of the crests are engaged to the inner surface of the outer wall and each of the troughs are affixed to the outer surface of the inner wall.

Grinder pump station

A grinder pump station capable of having its height adjusted in the field during installation has a longitudinal tank having a substantially cylindrical non-corrugated inner wall secured to a substantially cylindrical corrugated outer wall, a separate transition section for mounting a grinder pump unit within the longitudinal tank, a removable lid assembly attached to the top of the longitudinal tank, and a base attached to the bottom of the tank. A grinder pump unit may be mounted inside of the tank. The removable lid assembly includes an electrical and ventilation interface for the grinder pump unit mounted in the tank, thereby facilitating adjustment of the height of the tank through variation in its longitudinal extent without interference with the electrical and ventilation interface. The transition section separates an upper tank portion from a lower tank portion, preferably has a non-corrugated side wall, and includes a sewage inlet opening and a sewage outlet opening through its side wall.

Grinder pump station and method of manufacture thereof

An integral, readily installed, universal pump assembly has an integral, liquid-tight outer housing for supporting within a single liquid-tight containment vessel an electric motor driven pump, and discharging liquid from a discharge outlet of the pump. The assembly includes at least one normal high and low liquid level sensing control pneumatic pressure operated electric switch supported within the housing for deriving on-off switching control signals for controlling normal on-off operation of the pump. At least one liquid level sensing diving bell is supported on the housing and has at least one lower open end exposed to the liquid in the collection tank for deriving varying pressure pneumatic liquid level indicating signals for application to the pressure operated switch for deriving the on-off control signal. A dynamically operated liquid level safety cutoff valve is provided within the sensing diving bell for cutting off leakage of liquid into the normal on-off control switch upon the liquid level in the sensing diving bell exceeding a predetermined level. A second liquid level sensing diving bell and pressure operated control switch may be added for deriving a high liquid level alarm output signal. The housing contains a single, closed, liquid-tight chamber in which both the pneumatic pressure operated on-off control switch and a high liquid level alarm pressure operated, control switch
