A drape according to the present invention is constructed of or includes conductive and insulating drape segments and is disposed over a top surface of a thermal treatment system having a basin recessed therein. A portion of the drape is pushed down into, and conforms to, the basin to form a drape container or receptacle within the basin for collecting a sterile medium. The conductive segments provide a signal indicating the presence of liquid and/or leaks within the drape container to the system to facilitate control of system operation. In addition, a drape utilized for a plural basin thermal treatment system may form a drape receptacle within each basin. Each drape receptacle includes conductive and insulating drape segments to detect the presence of liquid and/or a leak within that drape receptacle. The conductive segments of the drape receptacles provide signals to the system to facilitate control of system operation.
