In a vaguely Medieval setting with some limited magic, how would an underwater city handle sewage?
Sanitation was one of the biggest limiting factors in the growth of human cities, and being under water is going to make the usual ways of removing sewage less feasible.
Some points:
- These cities are built in areas of weak currents.
- Magic exists but isn't all powerful.
- Magically creating currents on a city scale would cost more then the rulers can/want to spend.
- The inhabitants can breathe water and are mostly humanoid.

One imagines it would work exactly the same way fish currently "handle" their sewage. Or the way air-breathers "handle" their carbon dioxide output. One organism's output is another organism's input. Your city will be a bit hazy from the algae.

@AlexP as far as I understand, the sewage was dumped into the river by the way of the open and closed ditches. The river went out to the sea, it didn't bother population much after that. This system relies on strong currents and gravity assist.

(a) Are you asking only about sewage, or all forms of sanitation? (the latter might be too broad, so I'm hoping for the former). (b) How many people, on average, are in a city? (c) How far underwater are they? Please measure from water surface to the ground. (d) A weak current is mighty powerful when a lot of water is involved. What, exactly, is a "weak current?" (e) Most natural water isn't all that clean to begin with. After all, fish poop when they need to, current or not. How "clean" must the water be? Said another way, how much sewage/sanitation are we moving and why?

Two factors are important here
- one, there are consistent currents, strength is less important than consistency.
- two, sea floors are not, generally, flat on a large scale.
Taken together this means that getting sewage downhill and/or down current away from a city should be possible and even practical making it "someone else's problem" which is what medieval cities traditionally did and to some extent what we still do to this day.

Perhaps a siphon type system can be rigged up, no magic required, just poo into a constantly sucking pipe, or a pipe that requires a few actuation of a hand/ foot pump to create the suction. The pipes can lead out of the area, or into a deep sea crevice. Out of sight out of mind, especially for the medieval types.

One imagines it would work exactly the same way fish currently "handle" their sewage. Or the way air-breathers "handle" their carbon dioxide output. One organism's output is another organism's input. Your city will be a bit hazy from the algae.

@AlexP as far as I understand, the sewage was dumped into the river by the way of the open and closed ditches. The river went out to the sea, it didn't bother population much after that. This system relies on strong currents and gravity assist.

@Cumehtar: Ah! So an underwater medieval city, which is already in the sea, what will it do with the sewage?

(a) Are you asking only about sewage, or all forms of sanitation? (the latter might be too broad, so I'm hoping for the former). (b) How many people, on average, are in a city? (c) How far underwater are they? Please measure from water surface to the ground. (d) A weak current is mighty powerful when a lot of water is involved. What, exactly, is a "weak current?" (e) Most natural water isn't all that clean to begin with. After all, fish poop when they need to, current or not. How "clean" must the water be? Said another way, how much sewage/sanitation are we moving and why?
