System and method for disinfection of a plumbing system associated with liquid waste

A thermal disinfection system configured for use with a liquid-carrying conduit existing in place (i.e., in situ) in a plumbing system existing in place (i.e., in situ), the thermal disinfection system comprising:

• a heating device configured for thermal contact with at least a portion of said liquid-carrying conduit, thereby defining a thermal contact region of said liquid-carrying conduit;
• a thermal insulating layer disposed on said heating device configured to be located on a surface of said heating device opposite from said liquid-carrying conduit;
• wherein said thermal disinfection system is configured to be installed in the field on said liquid-carrying conduit that is existing in place (i.e., in situ) in said plumbing system that is existing in place (i.e., in situ);
• and
• wherein said heating device is configured to heat and dry a lumen defined by said liquid-carrying conduit along said thermal contact region to a specified temperature to prevent or inhibit microbial activity from advancing through said lumen defined by said liquid-carrying conduit.
