In one delightfully surprising, attention-grabbing event, the 50 year anniversary of the completion of a concrete water tower, was celebrated. Esem provided a new appreciation of this imposing structure that some took for granted or perhaps even saw as a blight on a sedate low rise, Federation-housed landscape.

High in the sky images projected an unprecedented engineering marvel of the 1960s. The Petersham water tower sits atop of huge hidden reservoir carved out of bedrock in the 1880s. Architecturally innovative, its construction was an engineering feat, partly met by being one of the first major city works to use computers to test for structural stress. And the people responsible? Their names and faces were finally up in lights.
