Root Control

Roots and grease are the #1 cause of sewer system overflows (SSOs), creating havoc for system owners and residents. Problems such as I&I, decreased capacity, increased PM costs and unnecessary overtime and man-hours are common effects of systems that are left untreated. The best course of action is preventive care, ensuring your sewer pipes stay healthy and root-free.

Duke’s Root Control utilizes Razorooter® for root removal. Razorooter® is a chemical-laden, thick foam that has the consistency of heavy shaving cream. Since effectively killing tree roots in sewer systems requires access to the entire line, the Duke’s crew inserts a hose from manhole to manhole. The hose releases and sprays the foam in all directions, allowing it to adhere to roots and penetrate through wye connections to kill roots, even in lateral lines. The entire system is treated as the foam compresses against pipe surfaces and penetrates cracks, joints and connecting sewers. This treatment kills roots on contact inside and outside the pipe walls. The roots then decay naturally and slough away, with regrowth delayed for two to three years. Razorooter® does not harm trees and other above ground vegetation, and disruption to residents and businesses is minimal.

Of course there are other methods for removing tree roots from sewer pipes. They can include mechanical root removal and either replacement or lining of existing sewer pipes.

• Mechanical root removal involves physically cutting away roots. This can damage pipes and lead to thicker regrowth, often requiring more frequent cutting.

• Replacing or lining a pipe is another option for root removal. This method, however, is expensive, can be disruptive and doesn’t guarantee the thirsty roots won’t find their way through the pipe once again.

Regardless of the method used, the best root control program is one that minimizes damage, disruption and costs through regular, proactive maintenance. Duke’s exclusive root control chemicals translocate up the roots with each application. This preventive maintenance prolongs the life of your pipes, providing you with substantial cost savings in the long run.
