STI/SPFA members build steel water pipe that meets or exceeds the requirements of ASCE, AWWA, SWPMTAC, and all industry standards for water transmission. The welded steel pipe built by Members is available in diameters up to 180 inches under either internal or external pressure.
STI/SPFA members are involved in standards development activities and have written several design manuals, developed design software, and are actively involved in research projects testing joint efficiencies and recommending coating procedures on internal welds after backfill is in place.

STI/SPFA honors utility management companies or agencies whose steel water pipe or pipeline has been in continuous service in the water delivery infrastructure for more than 100 years. This honor demonstrates the strength and durability of steel for use in the water infrastructure. With rising concern about the aging of infrastructure components across the nation, STI/SPFA’s Steel Water Pipe Century Club recognizes utilities that have properly maintained their steel pipe components, resulting in 100 years or more of uninterrupted delivery of clean drinking water critical for sustaining community growth, commercial growth, industrial growth and, most importantly, for sustaining life.
