How come all sewers don’t stink?

Question

Sometimes ones in the city do. But like, why not all sewers? Do the good ones have valves that hold all the poop and pee back?

I’ve worked around a few sewers before, one thing that did often stand out was the smells of detergents and soaps. On a cold day in the morning, you’d get the showers and washing water, and it would be pretty warm in them too.
There would be more soaps and shower gel than crap, so they wouldn’t be all that bad.
