Carbon steel, galvanized carbon steel and copper have been traditional materials used for building water supply piping. For many small buildings, the maintenance for these systems is tolerable. For larger buildings, where high reliability in service is necessary, and for the handling of various water qualities and conditions, the maintenance costs may be higher than desired by building owners and reliability lower than required by operators of electronic equipment.

Stainless steel piping is an alternate material that offers high reliability, when properly designed and installed. Although water treatment is still required for scale, dirt and biological control, performance of stainless steel is much less dependent upon water treatment, flow velocity, turbulence and other conditions affecting carbon steel and copper piping. Japan has been successfully using stainless steel in high reliability building water supply systems for some years. This paper identifies key procurement, fabrication and water treatment guidelines for a low maintenance, high reliability stainless steel building water supply system.
