A number of water main breaks occur every year in municipalities due to ageing, aggressive environmental conditions and undesirable soil conditions. However, the failure mechanism observed in cast iron water mains is often obscure. Non-uniform soil support conditions resulting from the erosion of the surrounding soil by the water escaping from leaks may induce excessive stresses on the pipe wall. Due to partial erosion of backfill soil or the presence of large rock pieces, the localised point su...

AbstractCircumferential cracking or ring fracture has been identified as the most common type of failure mode for cast-iron water mains. However, the cause of circumferential cracking in water main...
