Where does my poop go?

I know there are sewers and stuff, but does it stay there? If so, why doesn't it overflow? WHERE IS MY POOP?

It goes to a sewage treatment plant. When it gets there, it is collected in a pool filled with water and aerobic bacteria. The bacteria eats the organic compounds in the poop. The remaining sludge is collected, dried, and shipped to landfills.
