manhole city street sewer sewage 1200923

As I’m working on a new PDF about sewers, it seems fitting to have this week’s “10 Questions..” series be about the same topic.

Some of these prompts/questions can be applied to individual settlement sewer systems or the concept as a whole.


  1. How old is the sewer system?
  2. How extensive is it/how much area does it cover?
  3. Are there regional variations in terms of design, how much it can handle etc?
  4. How is it accessed for maintenance and so forth?
  5. Who is in charge of upkeep and how do they raise funds to do so?
  6. Are there any urban legends regarding sewers?
  7. Where ultimately do the sewers lead to?
  8. Does any flora/plants etc grow in there?
  9. What creatures, living or otherwise, call this place home?
  10. What is allowed to be put into sewers and how is it monitored?

Bonus question : Are there any famous stories or tales that feature sewers heavily?
