How Tree Roots End Up in Sewer Lines

Trees bring more life and vibrancy to any yard and landscape, but their roots can also cause unexpected damage to underground sewer systems. USA Pipe Repair, the go-to expert in trenchless pipe lining in Richmond, VA, explores how roots end up in sewer lines and the possible solutions to this problem.

Why Roots are Attracted to Sewer Lines

Tree roots naturally seek water and nutrients to sustain the tree’s growth. Sewer lines, especially older ones, often provide an ideal source of both. Small leaks or cracks release moisture and organic material into the surrounding soil. Once roots detect this, they begin growing toward the source, eventually finding their way into the pipes. It’s not uncommon for pipe lining companies like USA Pipe Repair to encounter repairs that involve clearing out tree roots from sewer lines.

How Roots Enter the Pipes

Even the smallest cracks, gaps, or loose joints in sewer pipes can be entry points for tree roots. Once inside, they continue to grow and expand, eventually causing blockages and even pipe breakage. Older pipes made of clay, cast iron, or Orangeburg (bituminized fiber pipe) are particularly vulnerable to root intrusion. Cast iron pipe lining creates a smooth, impenetrable barrier against tree roots, and can be recommended if the original pipes are still structurally sound.

Do All Trees Cause Problems?

Some tree species, like willows, poplars, and silver maples, have more aggressive root systems and are more likely to cause issues with sewer lines. However, any type of tree can potentially cause problems if planted too close to underground pipes. It’s a good idea to do some research before planting trees in your yard, and for good measure, keep them at least 10 feet away from where your sewer pipes are located.

Addressing Tree Root Intrusion

An effective way to address tree root infiltration is CIPP pipe lining. After a thorough inspection, the pipes are cleaned and cleared of any roots, debris, or buildup. A resin-saturated liner is then inserted through a cleanout or small access point, inflated, and cured to create a durable, seamless pipe within the existing one. This new inner layer seals any gaps or cracks and is more resistant to issues like corrosion and root intrusion.
