Abstract
A heated fluid is used as a thermal herbicide for scalding and killing roots growing within sewer lines. The process includes the steps of heating a fluid, isolating a length of a sewer line, and then filling the isolated length of sewer line with the heated fluid for a lethal period of time required for the heated fluid to act as a thermal herbicide for killing the roots within the length of sewer line. When treating an adjacent length of the sewer line, the preheated fluid is removed from the preceeding section, reheated, and then inserted into the adjacent isolated length of the sewer line.
