Water pipe network

In the ACT, we deliver more than 100 million litres (100,000,000 l) of water each day to ACT residents. Water from the Mount Stromlo and Googong water treatment plants is delivered by bulk supply mains to 47 urban service reservoirs. From here the water is fed into distribution mains to transport it to households.

The size of these pipes in the network are designed to transfer enough water for all the households serviced by the reservoir in a 24 hour period. Pipes can be as thick as 1500mm (1.5 metres) in diameter near the treatment plant. They can be as small as to 100mm in diameter for pipes leading to the smaller reservoirs.
