Abstract: A system and method for a process to prepare piping such that it has a reduced chance of having biological organisms developing or growing within it by the addition of a metal structure to at least a portion of the inner wall of the piping. The system utilizes a limited amount of metal on or close to the inside wall of the piping to retard or suppress the growth of biological organisms within the piping. The limited amount of metal inside the pipe does not materially interfere with the structural aspects or performance of the pipe, nor does it significantly increasing the material costs of the pipe, while providing a unique and novel improved anti-biologic organism performance. The system is suitable for residential or commercial use.
