Claim 4:
5. A method for retarding the growth of biological organisms in piping by attaching a biocidal metal structure in the piping, by:
choosing a piece of piping that a substance may pass through;
choosing a metal structure of at least an equal length as the piping;
placing the metal structure in at least a portion of the piping;
passing an electric current through the metal structure such that the metal structure gets hot enough to fuse at least a portion of the metal structure to at least a portion of the inner wall of the piping;
the metal structure is attached to the piping such that at least a portion of the metal structure is exposed to the inner area of the piping and at least a portion of the metal structure may be exposed to at least a portion of the substance passing through the piping.
