See a city of 200,000 swept away by sewage in Cities: Skylines

40 Citiesskylines

Scientists use Cities: Skylines, asking how a town of 200,000 people fares when hit by a sewage tsunami, or sewagenami.

As you can see, living conditions take a hit, parks are likely to remain closed for some time, and slip roads become skid roads. That, and everyone's dead. Good work, chap; get this peer reviewed pronto.
