What were sewer pipes made of in the 1950s?
In the 1950s, ductile iron pipe was introduced as an improvement on cast iron. It has higher strength and similar corrosion resistance, making it an attractive material for water and wastewater uses. Similar to cast iron, there were also many types of linings developed to prevent corrosion in the interior of the line.
What is terra cotta pipe used for?
This material, also referred to as terra cotta, is stronger and fits together more tightly than older clay plumbing. It’s still routinely used in public sewer systems today. Modern installations include encasing the clay pipes in concrete to protect against root intrusion and damage from ground shifting.
What kind of sewer pipes are used in older homes?
Older Homes: Clay, Cast-Iron, and Orangeburg In older properties built before the 1950s, you might find clay pipe, cast-iron pipe, or a fiber conduit pipe called Orangeburg.

What kind of sewer pipe is bituminized fiber?
Bituminized fiber drain and sewer pipe (a.k.a. Orangeburg pipe). This type of sewer pipe (2” – 18” diameter) was manufactured as an oval conduit* for wiring, etc., from the 1890s to the early 1940s; thereafter, it was made as a round pipe until the 1970s.
Where did the fiber conduit pipe come from?
Early on fiber conduit pipe was called “Alkacid” by the Fiber Conduit Co. of Orangeburg, NY. The oil industry soon stopped using the fiber “Alkacid” pipe, and started using a cement-asbestos pipe. 1948 saw the name Fiber Conduit Company changed to the Orangeburg Manufacturing Company.
What kind of material is a sewer pipe made of?
During the industrial age in the United States, a new type of conduit pipe evolved, made of wood fibers bound together with a water resistant adhesive, and, thereafter, infused with liquefied (hot) coal tar pitch.
