I am in college to become a wastewater technician, and while the major involves practical work skills, we do not learn any history at all (beyond ones tied to safety rules/regulations). Providing clean drinking water, and disposing of waste water, is incredibly important to the development of civilization... but it feels like it's weirdly difficult to find historical accounts of what practices we used in the past.

So I'm wondering how we provided drinking water and transported wastewater during about the industrial revolution era. At this point, sewers were built--but then what? What did the process treatment path look like? What techniques did we use to dispose of sewage? Same with drinking water, how did we clean it before it was sent to people's homes? Municipal water wasn't widespread until the 19th century, but how did drinking well systems work during this time period? etc
