Learn about what an Orangeburg sewer pipe is and why it matters

Although Washington Energy can not support plumbing services involving Orangeburg Pipe or sewer, it’s important to us you understand the potential risks if your home still utilizes Orangeburg sewer pipes.

Orangeburg pipe is bituminous fiber pipe made from asphalt and layers of wood pulp which is pitch-pressed together – essentially tar paper. Lightweight and brittle, this piping absorbs moisture and deforms under pressure. It started out as a substitute to cast iron pipe, which was heavily taxed during WWII to support the war effort.

How long does Orangeburg pipe last?

Orangeburg has a life expectancy of approximately 50 years. After 30 years, deformation may begin to occur. All homes with Orangeburg pipe are pre-1972 and 40 or more years old. That could put your house at risk.

What happens when the Orangeburg piping begins to deteriorate?

Once the product begins to break down homeowners can expect frequent clogged lines, tree root invasion and even total pipe collapse. Once the deterioration process begins, Orangeburg sewer pipes deform quickly, allowing tree roots to break in to them and literally shred them.

How do you tell if your Washington home has Orangeburg pipe?

If your house was built between 1940 and 1972, there’s a chance you have Orangeburg. The product was used as the standard piping as late as the 1970’s. Also, if you have frequent clogs in your main sewer line or you see indentations in the front yard that line up with where the sewer should be, it’s might be a sign of Orangeburg pipe deterioration. If your neighbors have Orangeburg, you probably do too.
