Abstract
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...
