Pipe bursting is a trenchless method of replacing buried pipelines (such as sewer, water, or natural gas pipes) without the need for a traditional construction trench. "Launching and receiving pits" replace the trench needed by conventional pipe-laying.
The pipes were hollowed-out logs which were tapered at the end with a small hole in which the water would pass through. [23] The multiple pipes were then sealed together with hot animal fat. Wooden pipes were used in Philadelphia, [24] Boston, and Montreal in the 1800s. Built-up wooden tubes were widely used in the US during the 20th century.
Prestressed concrete cylinder pipe (PCCP) is a common variety of large-diameter concrete pressure pipe used for transporting water and wastewater. PCCP is typical manufactured according to the American Water Works Association (AWWA) standard C304. [ 1 ]
[3] [4] Roman roofs used lead in conduits and drain pipes [5] and some were also covered with lead; lead was also used for piping and for making baths. [6] The Latin for lead is plumbum. In medieval times, anyone who worked with lead was referred to as a plumber; this can be seen from an extract about workmen fixing a roof in Westminster Palace ...
