It is estimated that Roman Sewers were invented between 800 and 735 BC. The open channel Cloaca Maxima is guessed to be built sometime between the sixth and fourth century BC. It was built to drain the low lying land that was in the Forum. From the Cloaca Maxima, a network of sewers was gradually built. Most Roman sewers emptied into the Tiber and were for draining water above and below ground. Waste from people was thrown into the street and most was swept into this network of sewers with aqueduct water.

Romans
Yes. Romans were the first empire to really care about hygeine and health. They created sewers, latrines (the first toilets), the Roman baths (public cheap baths which everyone could afford to go to), and the aqueducts, which provided up to 80 gallons of fresh water for every one in the city each day.
The Romans, like everyone else in those days, built walls and fortifications around their towns.
The Etruscans were considered to be the first romans!

The Romans built sewers for the reasons one builds sewers: to channel and dispose of waste and for hygiene.

For a short answer- they were not. Here is a more detailed explanation why. The Romans were not unclean because they built some of the first sewers and they often visited the public baths. The Romans were among the first people to frequently wash. Their bathhouses were a place where anyone could go- even slaves- and it was free. They used sewage systems to remove waste from their cities. Some of their sewers were so good that they are still in use today.
