Plumbing originated during ancient civilizations such as the Greek, Roman, Persian, Indian, and Chinese cities as they developed public baths and needed to provide potable water and wastewater removal, for larger numbers of people. Roman roofs used lead in conduits and drain pipes and some were also covered with lead, lead was also used for piping and for making baths. Plumbing reached its early apex in ancient Rome, which saw the introduction of expansive systems of aqueducts, tile wastewater removal, and widespread use of lead pipes.
Most large cities today pipe solid wastes to sewage treatment plants in order to separate and partially purify the water, before emptying into streams or other bodies of water. For potable water use, galvanized iron piping was commonplace in the United States from the late 1800s until around 1960.

The thicknesses of the water pipe and tube walls can vary. Pipe wall thickness increases with schedule, and is available in schedules 20, 40, 80, and higher in special cases. Wall thickness does not affect pipe or tubing size.
