It can be said that in some households it was, although not in most of them.
During the days of the Roman Empire, in the city of Rome the water was supplied by means of aqueducts, some canals commonly underground, but that also were constructed, depending on the unevenness in the land, on bridges with arches.
The aqueducts brought water from the mountains to the city's public water sources, where most citizens were supplied with the water they needed.
Some wealthy Romans connected their homes directly to the city's water network allowing them to have fresh water all the time.
However, the water did not go beyond the first floor of a building, which meant that a large part of the Roman population, who lived in multi-story buildings, did not have that privilege.
