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.

3. Pumping station - Wikipedia

   en.wikipedia.org/wiki/Pumping_station

   A four pole or six pole AC induction motor normally drives the pump. Rather than provide large open passages, some pumps, typically smaller sewage pumps, also macerate any solids within the sewage breaking them down into smaller parts which can more easily pass through the impeller. The interior of a sewage pump station is a very dangerous place.

   In a typical set-up, a receiving well is provided close to the properties being served so that all sewage can gravitate to the well. An electric macerator pump (also called a grinder pump) pumps the finely macerated sewage through a narrow diameter continuous plastic pipe which discharges into the nearest gravity sewer or treatment plant. The ...

6. Vacuum sewer - Wikipedia

7. Jet aerators - Wikipedia

   en.wikipedia.org/wiki/Jet_aerators

   Jet aerators can be installed either as submersible units or piped through the tank wall using an external dry-installed chopper pump to feed the aspirating ejector(s). Jet aerators are easily configured into any basin geometry including circular, rectangular, looped reactors and sloped wall basins.
