What Are Orangeburg Pipes?

Orangeburg is a type of sewer pipe made from wood pulp fibers saturated with coal tar pitch. It was widely used from the 1940s through the 1970s, particularly during rapid suburban development.

The problem?
It was never designed to last long-term.

Over time, Orangeburg pipes absorb moisture, lose structural integrity, soften, deform, and eventually collapse. If your home was built before 1980 and the sewer line has never been replaced, there is a real possibility that Orangeburg is still buried beneath your property.


Why Simi Valley Homes Are at Higher Risk

At Sewer Scope Pros of San Fernando Valley, we perform sewer camera inspections throughout Los Angeles and Ventura Counties. Among all the cities we serve, Simi Valley consistently shows the highest concentration of Orangeburg sewer lines.

Many Simi Valley neighborhoods were developed during the post-World War II housing boom—exactly when Orangeburg was the material of choice. In recent inspections, we repeatedly encounter severely deteriorated Orangeburg pipes that are well beyond their intended lifespan.


Common Problems with Orangeburg Pipes

Orangeburg pipes are not just outdated—they are structurally unstable. During inspections, we commonly find:

Because Orangeburg softens and deforms when wet, it loses its round shape and restricts flow, creating chronic drainage issues and sudden failures.


Sewer Line Issues Common in Simi Valley

In addition to Orangeburg failures, sewer inspections in Simi Valley frequently reveal:

When Orangeburg is present, however, the risk of total collapse is significantly higher. These pipes often resemble wet cardboard after decades underground—and when they fail, they fail fast.


How to Know If You Have Orangeburg

The only reliable way to identify pipe material and condition is with a sewer camera inspection. A standard home inspection does not evaluate the sewer lateral.

During a sewer scope, a high-definition camera is inserted into the main sewer line to inspect:

Typical visual indicators of Orangeburg include:

If Orangeburg is present, the condition is documented and explained clearly, along with realistic next-step options.


Protecting Your Home and Your Investment

If you own—or are buying—a home in Simi Valley that was built before 1980, a sewer inspection is one of the smartest preventative steps you can take.

Sewer line replacement can cost tens of thousands of dollars, and interior damage from backups can be even more costly. Knowing the condition of your sewer line in advance allows you to:

A sewer inspection is a small investment that can prevent major financial surprises.


Final Thoughts

Simi Valley has a disproportionately high number of homes with aging, high-risk Orangeburg sewer lines. These pipes often fail silently—until the day they collapse.

If your home was built during the post-war boom or you’re purchasing in one of Simi Valley’s older neighborhoods, a sewer camera inspection is essential.
