queducts were built in ancient Rome to move water. Transporting water was a difficult problem before modern plumbing. Roman aqueducts carried water across valleys or hillsides using gravity, above ground stone arches, and underground pipes made of stone and clay. Water was brought to Rome from 57 miles away by 11 aqueducts.
They got the fresh water from springs underground and moved it many miles.
Once the water made it to Rome, it was stored in collecting tanks. Most people gathered there water from these tanks each day. Only the rich and officials in the government had private water tanks in their home.
Many Roman aqueducts still stand today. Engineers today agree that the ancient Romans were the greatest aqueduct builders ever.
