A really great fictional work, Pompeii by Robert Harris, has a hero who is a newly appointed water engineer for Pompeii. The young engineer Marcus Attilius Primus has just taken charge of the Aqua Augusta, the enormous aqueduct that brings fresh water to a quarter of a million people in nine towns around the Bay of Naples. His predecessor has disappeared. Springs are failing for the first time in generations.
Thanks for the recommendation. Sounds interesting and I am a voracious reader.
