I think, I'll add that to my answer, thanks :-) | |

I'd expect some minor spillage in the process of collecting the sewage, and without a good water supply it's not convenient to just shower off, so it's more disease risk for your population even just to keep sewage sitting around in the open until its time to lower it down and use it's gravitational potential energy. | |
