Orangeburg Pipe at a Glance
What is Orangeburg Pipe?
Orangeburg pipe (also called "fiber conduit" or "Bermico pipe") is a type of bituminous fiber pipe made from layers of ground wood pulp fibers bound together with coal tar pitch. The name comes from Orangeburg, New York, where the Fiber Conduit Company manufactured it starting in the 1860s.
Originally designed for electrical conduit, Orangeburg became popular for residential sewer lines from the 1940s through the early 1970s because it was:
- Inexpensive - Cost significantly less than cast iron or clay
- Lightweight - Easy for workers to carry and install
- Simple to cut - Could be cut with a hand saw
- Marketed as "no corrode" - Unlike metal pipes
The pipe was marketed with a 50-year lifespan, but real-world performance has shown that most Orangeburg pipes fail within 30-50 years. Since the material hasn't been installed since the early 1970s, virtually all remaining Orangeburg pipes are now at or beyond their expected lifespan.
⚠️ Why Orangeburg Fails
Orangeburg pipe absorbs moisture over time, causing it to soften, deform, and eventually collapse. The tar pitch binder breaks down, and ground pressure causes the round pipe to become "egg-shaped" or completely flat. Tree roots easily penetrate the softened material, accelerating failure.
Orangeburg vs Cast Iron: Key Differences
| Feature | Orangeburg | Cast Iron |
|---|---|---|
| Material | Wood pulp + coal tar | Iron alloy |
| Lifespan | 30-50 years | 75-100 years |
| Common Use | Sewer lines (underground) | DWV systems (inside home) |
| Failure Mode | Softens, deforms, collapses | Corrodes, cracks, root intrusion |
| Trenchless Repair | Excellent (soft = easy to burst) | Good (harder material) |
| Replacement Cost | $3,500-$15,000 | $8,000-$25,000 |
Many homes built 1945-1975 have both Orangeburg (sewer line) and cast iron (interior drains).Learn about cast iron pipe replacement →

How Orangeburg Pipe Replacement Works
Schedule a Sewer Camera Inspection
Contact a licensed plumber for a video camera inspection ($150-$400). The camera footage will confirm if you have Orangeburg pipe and reveal its current condition—deformation, cracks, root intrusion, or collapse.
Get Multiple Quotes
Request written quotes from at least 3 licensed plumbers. Compare trenchless (pipe bursting) vs traditional excavation options. Ask about warranties—quality contractors offer 10-25 year warranties on new pipe.
Choose Replacement Method
Trenchless pipe bursting is ideal for Orangeburg because the soft material breaks apart easily. Traditional excavation may be needed if the line has multiple bends or is under permanent structures.
Contractor Pulls Permits
Your licensed plumber obtains necessary permits from your local building department. Never skip permits—unpermitted work creates problems for resale and may void warranties.
Replacement Work (1-3 Days)
Trenchless replacement typically takes 1 day. Traditional excavation takes 2-3 days. The old Orangeburg is removed (or burst apart) and replaced with modern PVC or HDPE pipe.
Final Inspection and Testing
City inspector verifies code compliance. Your plumber performs a final camera inspection and flow test to confirm proper installation and drainage.
