Grinder pumps can be installed in the basement or in the yard. If installed in the yard, the holding tank must be buried deep enough that the pump and sewage pipes are below the frost line. A grinder pump is different from a sump pump or effluent pump. There are two types of grinder pumps, semi-positive displacement (SPD) and centrifugal.
KOS+ M openwell submersible pump. Small-scale sewage pumping is normally done by a submersible pump.. This became popular in the early 1960s, when a guide rail system was developed to lift the submersible pump out of the pump station for repair, and ended the dirty and sometimes dangerous task of sending people into the sewage or wet pit.

When the sewage level rises to a predetermined point, a pump will be started to lift the sewage upward through a pressurized pipe system called a sewer force main if the sewage is transported some significant distance. The pumping station may be called a lift station if the pump merely discharges into a nearby gravity manhole. [4]
Grinder pumps are typically used for light weight sewage applications, whereas chopper pumps are used for tough solids handling applications. The chopping system consists of a set of rotating cutters that are keyed to the shaft and work in conjunction with the stationary cutters, which are bolted to the suction plate.
The engine house would contain the engine, the generator, the necessary switchgear and fuses, as well as the engine's fuel supply and usually a dedicated workshop space with equipment to service and repair the engine. Wealthy households could afford to employ a dedicated engineer to maintain the equipment, but as the demand for electricity ...
It is the most powerful water lifting system in the world, not considering pumped-storage hydroelectricity stations. [1] There are 14 4-stage 80,000-horsepower centrifugal pumps that push the water up to the top of the mountain. Each motor-pump unit stands 65-feet high and weighs 420 tons. The pumps themselves extend downward six floors.

The deaerator lift pumps discharged the condensate to the deaerator and from there it passed through microwire and magnetic filters to the boiler feed pump suction main. The main boiler feed pump was driven by a steam turbine which received its steam from the main H.P. turbine exhaust.
