Metro weekly water update – 18 January 2019
Note: 1 billion litres = approx. 400 Olympic swimming pools. Please note these figures are rounded (except for rainfall) to the nearest whole number.
Average daily water use over the last week was 997 million litres, which was slightly below the forecast of 1.053 billion litres.
Since 1 July 2018, we have used 151 billion litres of water - this is 5 billion litres above what we had forecast for this period. It’s worth noting our forecast for winter/spring was more ambitious than previous years and actual total water use is around the same as this time last year.
Dam level (total for 15 dams)
The dam storage level has remained steady over the past week, sitting at 53 per cent* of full capacity.
*Please note some dams are filled from different sources - dam levels include the transfer of groundwater and desalinated seawater from treatment plants as well as streamflow (that comes from rainfall). Dam levels are no longer an accurate indicator of the status of Perth's water supply situation.
Streamflow (total for 15 dams)
From 1 May 2018 to 17 January 2019 the dams have received 147 billion litres of streamflow. The post-1975 average for the May to January period is 181 billion litres.
Sprinkler roster compliance
The two-day-a-week sprinkler roster now applies across Perth, so make sure your sprinklers are programmed for your rostered water days and only to come on once, either before 9am or after 6pm.
Our team of inspectors issued 108 warnings and 129 fines this week. Since 1 January 2019, we have taken a total of 483 actions (warnings + fines) compared with 256 actions for the same period in 2018.
Perth has received 1.8 mm of rainfall since 1 January. Average rainfall for January (1994-2017) is 16.7 mm.
