Depends on where you live.
In some places it is piped into the nearest river, lake, or ocean. In others, it goes through primary treatment (allow solids to settle) and then is piped into the nearest river, lake, or ocean. In some cases, it goes through multiple layers of treatment (secondary treatment might consider of filters, bacteria to remove heavy metals, chemicals to kill harmful bacteria or reduce the PH level, etc.), and then it piped into the nearly river, lake, or ocean.
In some cases, treated water might be recycled back into housing for non-drinking water, into agricultural uses, etc. Some communities have separate water for say lawn watering, outdoor fountains, etc. vs. drinking water.
Evidentally not very well because they are finding pharmacuticals in our drinking water all over the world.
Call your city water treatment center to find out the answer to your question.
