History of the Aqueduct Trail

The O’Shannassy Aqueduct trail was designed to have a constant gradient and to operate completely by gravity, without the need for any pumps or other mechanical devices.  Construction began in 1911 with a total cost of $853,780.  Much of the aqueduct was dug by hand and took a little over 3 years to build and completed in October 1914.  Just in time to help Melbourne avert a major drought which affected most of Australia at the time.
