Handling Tree Root Infiltration in Sewer Lines

raameen irfan • Aug 25, 2023

Causes of Tree Root Infiltration

Tree roots seek water and nutrients, and sewer lines, often carrying wastewater and moisture, provide an ideal environment for roots to thrive. Several factors contribute to tree root infiltration in sewer lines:

  • Hydrostatic Pressure: 

Sewer lines contain moisture that can create a pressure gradient. Tree roots, with their innate ability to sense moisture, can grow toward these areas of higher moisture concentration.


  • Seeking Nutrients: 

Sewer lines can contain traces of organic matter, a valuable nutrient source for trees. Roots are naturally drawn to these nutrients, prompting them to penetrate the sewer lines.


  • Small Cracks and Joints: 

Even tiny cracks or gaps in sewer pipes can release moisture into the surrounding soil, attracting roots. As the roots grow, they can exploit these openings and infiltrate the sewer system.



  • Vapors and Condensation: 

Sewer lines emit vapors and condensation, which trees can detect. Roots can extend toward these sources of moisture, leading to infiltration.

Impact on Sewer Systems

Tree root infiltration can have significant negative consequences for sewer systems:

Clogs and Blockages: 

As roots infiltrate sewer lines, they can catch debris and grease, leading to blockages that impede the flow of wastewater. This can result in sewage backups, flooding, and environmental contamination.

Structural Damage: 

The force exerted by growing roots can crack and damage sewer pipes. As roots continue to grow and multiply within the pipes, they can cause structural weaknesses and even collapse.

Reduced Efficiency: 

Infiltration by tree roots can diminish the capacity of sewer lines, requiring frequent maintenance and reducing the overall efficiency of the system.



Maintenance Costs: 

Municipalities and property owners face increased costs for repairs, cleaning, and maintenance of sewer systems due to the persistent intrusion of tree roots.

Handling Tree Root Infiltration

Addressing tree root infiltration requires a combination of reactive and proactive measures.

1. Mechanical Augering: 

When root infiltration is detected, mechanical augering can be used to remove the roots and clear the pipes. However, this is a short-term solution and might need to be repeated frequently.

2. Hydro Jetting: 

Hydro-jetting involves using high-pressure water to break down and flush out roots from sewer lines. It can provide temporary relief but may not prevent future infiltration.


3. Chemical Treatments: 

Root-killing chemicals can be applied to sewer lines to deter root growth. However, this approach has environmental concerns and needs to be used cautiously.

4. Pipe Relining: 

In cases of structural damage, pipe relining involves inserting a new lining into the existing pipe, sealing off cracks, and preventing further root infiltration.

5. Root Barriers: 

Installing physical barriers made of materials like metal or plastic can prevent roots from accessing sewer lines. These barriers are typically installed underground near the pipes.

Preventing Future Infiltration

Proactive strategies are essential to prevent recurring tree root infiltration:

  • Species Selection: When landscaping near sewer lines, opt for tree species with less aggressive root systems. Avoid planting large trees near pipes.
  • Root Zone Management: Regularly inspect and maintain the area around sewer lines. Keep trees adequately watered to minimize the incentive for roots to seek out moisture from pipes.
  • Barrier Installation: Consider installing root barriers during construction or landscaping projects to discourage root growth toward sewer lines.


  • Regular Inspections: Conduct routine inspections using cameras or other technology to identify root infiltration early. Prompt action can prevent major issues.
  • Hydro Zoning: Design landscaping so that trees are planted farther away from sewer lines. This practice creates a hydrological buffer zone that reduces the likelihood of root infiltration.

Securing Sewer Systems

The integrity of sewer systems is seriously threatened by tree root intrusion, which could result in clogs, blockages, and structural damage. Municipalities, property owners, and urban planners must comprehend the root causes and effects of this incursion. It is possible to control and reduce the risks connected with tree root infiltration in sewer lines by putting in place a combination of proactive tactics, such as root barriers and species selection, and reactive measures, including mechanical augering and hydro-jetting. In the face of this ongoing problem, a comprehensive strategy that includes upkeep, prevention, and innovation will be necessary to guarantee the longevity and effectiveness of sewer systems.
