The Earliest Industrial Sewage system was developed and invented in twentieth century. This system is called Davyhulme Sewage Works, (the activated Sludge). This system was activated all over the world.
Completely depends on the size and application. The volume of debris required to grind and the materials it's comprised of will wear the grinder teeth and impeller. I would say it's safe to assume an average 1/2 HP residential sewage grinder pump running a single family home would run at least 5 to 10 years maintenance free. 20 years wouldn't be out of the possibility, but if you have a garbage disposal, frequently dispose of chemicals down the drain, or have a lot of usage I would say 20 years wouldn't be so likely, 10 would be more realistic.
