Start of summer sees storage levels dip


Melbourne's water storages decreased by 0.3% of capacity this week, representing a net loss of 5.5 billion litres.

The four major catchments received between 0.4 to 15.6 mm of rain, the average being 6.5 mm. This was 68.3% below the long-term average for the period of 20.5 mm.

The 6.1 billion litres of stream flow was 21.9% below the 30-year average for the period (7.8 billion litres).

Water storages are now 72.3% (1,309.9 billion litres) full, compared with 70.8% (1,283.4 billion litres) at the same time last year - a difference of 26.5 billion litres.

Melburnians used an average of 173 litres of water per person per day. This is 23 litres more 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.
