Sewer Systems
Plumbing is a thing of old though the systems we are used to now only came into existence not so long ago. Before now, when people had to ease themselves, they had to find different ways to do it. But as times changed, cities started building sewer systems that are different from what we know now – they had underground tunnels.

The tunnels were a “safe place” for people to get rid of their waste, and they would just throw any and everything in. But the issue is, there was no drainage system, so there was the potential for it to overflow. That leads us to wonder what the disaster was like when the drains would overflow.
