The Parmley System of Segmental Pipe Construction - Ohio

The Parmley System was a comprehensive system of reinforced concrete constructions (monolithic, segmental, and unit pipes). The first patent for the system was issued in 1902. This catalog features segmental pipe construction, which Parmley believed was one of the most efficient methods by which sewers and pipe lines could be built.
