Public Utilities/Services

[kalos72]

As my players and I talk about their plans to rebuild the NYC area one point keeps popping up as the major roadblock. Forgetting about food or electricity or marauders...

Fresh water and sewage treatment...without both any major population center is just a cesspool waiting for outbreaks.

The players are thinking public restrooms and water points...

My biggest problem is just not understanding how the modern system works honestly. How DOES a major city gets its water delivered? OR what does happen to the waste once I flush the toilet?
