Most sewage has primary treatment which removes solids such as fecal material , condoms, and anything else that is flushed. After that it gets secondary treatment which involves aereation either forced by blowers or in an oxidation pond. Then it is allowed to settle. The by now clear water is decanted off. Sometimes it gets tertiary treatment which is treatment with chlorine to remove any pathogens.
As one of the responders mentioned the Mexican city of Tiajuana does not treat sewage. This is a real problem for Imperial Beach, a city just south of San Diego.
The sludge that remains after the decanting is dried and eithe burned or can be used for fertilizer for golf courses or other non food plants. It can't be used to for plants that are to be consumed because it has a tendency to contain heavy metals that are bad for people or animals

Arrange to take a tour of your local municipal sewage treatment plant. I'm sure that you will feel much better about what is dumped back into our rivers and oceans.

In the U.S., sewer water is usually treated (i.e.: filtered) before we dump it into the river.
Poor countries, like Mexico, usually do not treat their water. So they dump raw poo into the ocean and rivers.
