Yes and it still widely used even today
Lead water pipes.
Because that was the best material they had at that time.
That was the best material they had.
At the time of the Roman Empire, the Romans used pipes made of lead, because it is a cheap metal that is easily worked into pipes, and which unlike iron doesn't rust. The Romans didn't worry about lead poisoning. Lead pipes continued to be used even into the mid 20th century, before we became more concerned about the danger of lead poisoning.
It wasn't. Aqueducts were made of stone, engineered to amazingly exact specifications, then polished and smoothed. Lead was actually advised against for the use in aqueducts, for its toxicity, by Vitruvius in De Architectura.

Because they had no better materials at that time.
Plastic was not invented during that time period.
Lead was used for water pipes because it is cheaper, more malleable, and more flexible, and can be welded together easily. But it should not be used for water pipes of any kind because of the risk of water contamination. Metals such as copper are more expensive but superior in performance, and modern PVC is much lighter and easier to use for drainage pipes, and for pipes not carrying great pressure.
The Romans used the first basic pipes, aqueducts, baths and many other innovations in water usage.
Lead is toxic to humans (causes brain damage) thus when using a solder to join copper water pipes it is best not to use a solder containing lead as this will get into the water passing through the pipes and slowly poison the user of this water.
