 From 2006 a new raw water pumping station and associated infrastructure were built on the reservoir's south-eastern side, including pipeline, power supply and access road.It was formerly the major distribution reservoir for Sydney's main water supply system until the commissioning of the Prospect Water Filtration Plant in 1996.The reservoir's role has since been changed to that of an off-line storage service reservoir, which covers daily fluctuations of demand in the distribution system.
