Melbourne's storages increase slightly


Melbourne’s water storages increased by 0.5% of capacity which is equivalent to a net increase of 9.1 billion litres during the week.

Storages are now 59.4% full (1,076.0 billion litres). At the same time last year storages were 68.3% full. The 8.9% drop over this time translates to a reduction in volume of 162.5 billion litres.

The four major catchments received an average of 27.2mm of rain, 5.2% below the long-term average.

10.8 billion litres flowed into dams during the week, 18.5% below the 30-year average.

Melburnians used an average of 135 litres of water per person per day. This is three litres less than the previous week.

Permanent water use rules are currently in place and Target 155 has been launched to encourage Melburnians to reduce water consumption.

Information on Target 155 is available on the Department of Environment, Land, Water and Planning’s website or by contacting your local water retailer.
