What might happen if tree roots enter an old drain?

When tree roots infiltrate an old drain, they can disrupt the flow of wastewater and create significant blockages. This occurs because the roots tend to grow toward the moisture within the drain, leading to their expansion and ultimately restricting the pipe's diameter. As roots continue to grow, they can cause additional obstructions by entangling with other debris that might be present in the drain, resulting in backups and increased pressure within the drainage system.

Blockages can lead to a host of issues, including sewage pooling, unpleasant odors, and potential damage to the drainage infrastructure, all of which necessitate repairs and maintenance. Understanding the behavior of tree roots in relation to drainage systems is crucial for preventing such complications and ensuring effective drainage operations.
