Only some of it comes back through the sewage system. A lot of it just ends up lost to evaporation, or being incorporated into products. Think about your typical use of water to irrigate farmland (which is the majority use of water in many places); you don't really get any of that back as freshwater discharge at all. If you did, that means they're irrigating too much to the point that they're flooding their fields and causing runoff.
