Since January 2019 Melbourne Water has been upgrading O’Shannassy Reservoir. With a high annual yield of 60 gigalitres (60 billion litres) it is a crucial part of Melbourne's storage reservoir system, providing many homes and businesses with world-class drinking water.
Constructed in 1928 by the Melbourne Metropolitan Board of Works, the reservoir has been upgraded over time with new technology to keep it working at its best. This project will ensure the reservoir continues to operate effectively by replacing the outlet pipe and tower structure.
Construction commenced January 2019 and is expected to be complete in mid-2020.
What to expect
O’Shannassy Reservoir is closed to the public so we expect minimal disturbance.
To ensure public safety, five kilometres of the O’Shannassy Aqueduct Trail from O’Shannassy Weir to Woods Point Road will be closed during the construction. Visit Parks Victoria's website for other walking tracks nearby.
Every effort has been made to minimise vegetation impact, but some removal will be necessary to complete the works. In accordance with statutory requirements any vegetation removal will be supervised by a qualified arborist and wildlife handler.
