Much of Roto-Rooter's excavation work involves digging up existing water and sewer lines and repairing the damaged pipe sections or replacing the entire pipeline. This can be a small job or a large one, depending on the region of the country and the severity of the damage. For instance, sewer and water lines in South Texas and Florida only lie a few feet beneath the ground because of a shallow frost depth and lack of basements. However, in colder climates, some sewer systems are buried anywhere from 4 to an even 18 feet underground. The depth is mandated by climate, depth of connecting infrastructure and local plumbing codes. The shallowest lines can be repaired by small Roto-Rooter crews with shovels. However, deeper sewer and water lines require larger, more sophisticated excavation equipment, like backhoes, mini excavators or other heavy duty machinery.
