Aqueducts were the way that places in Rome transported water to to their cities and towns. They were made from cement and concrete. They used gravity to transport the water from a water source that was higher than the city and it had long hollow shafts that let air into the aqueducts. They also had these big drops in the aqueducts so the water would gain speed and then go higher into another part that goes to the city, shown in the picture below.
There was approximately 260 miles of aqueducts but only 30 miles of them ar visible. Aqueducts wasn't their only way of transporting water in general, but for short distance like from on important building to another in the same city-state then thay would sometimes put then in a form of big jars and let horses pull them in a carriage.

This is an aqueduct that is going to one city-state in Greece. They were built with arches for better and sounder structure.
