Melbourne's storages up slightly

Melbourne’s storage levels increased by 4.5 billion litres, equivalent to an 0.3% increase.

The four major catchments received 20.9% more rain than the long-term average for the period.

However, the amount of water flowing into storages (8.8 billion litres) was 13.7% below the 30-year average.

Water storages are now 58.9% (1,066.9 billion litres) full, compared with 68.6% (1,242.6 billion litres) at the same time last year - a difference of 175.7 billion litres.

Melburnians used an average of 138 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.
