Mature trees add beauty and shade to landscapes, but their roots can cause extensive damage to sewer pipes. Roots grow into the pipes because they like it there! Sewer pipes contain water, nutrients and oxygen – the essential elements for trees to grow. Aside from sewer blockages and backups caused by FOGG, tree roots growing inside sewer pipes are one of the most expensive sewer maintenance items experienced by our customers. Roots from trees growing on private property and on parkways throughout the service area are responsible for many of the sanitary sewer service backups and damaged sewer pipes experienced in our community.
