Water Transmission Main Failure
Springfield Water and Sewer Commission
Water and Wastewater

Springfield Water and Sewer Commission suffered a catastrophic failure in a 54" diameter water transmission pipeline. The pipe section, put into service in 1928, failed along a longitudinal, shop-made weld seam near the top of the pipe.

During manufacture, the pipe segments were dipped in a coal tar coating for internal and external corrosion protection, and the pipe was joined circumferentially in the field with riveted seams. Based on the field and laboratory investigations, CPI concluded that the original seam welds had been of poor quality and contained numerous voids and areas of a lack-of-fusion between the filler and base metals. Additionally, rough weld surfaces caused original coating adhesion and film quality to be poor at the welds. Once the coating began to fail at the rough weld surfaces, corrosion of the weld metal occurred and, over time, the porous welds provided ideal conditions for corrosion to proceed. The weld joints eventually thinned to the point that they were not able withstand the internal water pressure, and the pipe failed.
