Stormwater drainage is one of the important infrastructures of any modern urban city. A well planned, operated and maintained stormwater system should drain stormwater runoff effectively during normal periods and during floods. However, with rapidly expanding cities, unanticipated problems from changinf land usage, system overloading, pollution and deteriorating environment cause problems to stormwater assets and contribute to its failure. These issues are more problematic in larger and older cities where replacement is costly. Kogarah Council, a local government authority in Sydney, Australia, is anticipated to face many of the challenges this problem poses as it manages the urban water cycle system in an integrated manner to protect, restore and enhance the stormwater assets. The council owns a significant part of these assets that were constructed back in the 1930s.
