Just to be complete: The innovation of Rome, most "exported" to the main cities of the empire, is the sewer systems. The city of Rome had a vast network of sewers as early as the 6th century BC, which brought the city waters to a large sewer collector which blossomed into the Tiber, (the Cloaca Maxima) and of which some remains can still be seen today.
