Metro weekly water update - 10 August 2018
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 595 million litres, which was above the forecast of 549 million litres. So far this current financial year we have used one billion litres of water more than the 22 billion litres we had forecast.
Perth’s dam storage levels have increased (by 19 billion litres) from 180 billion litres to 199 billion litres of usable storage (for the 1 August to 8 August period). Please note our dams store water from three different sources and this increase is due to groundwater and desalinated seawater transferred from treatment plants as well as streamflow (produced by rainfall).
Streamflow (total for the metro’s 15 dams)
*We are experiencing a technical difficultly with our streamflow reporting this week. As soon as the data becomes available we will include the information in this update and on our website. From 1 May 2018 to 2 August 2018 the dams had received 33.8 billion litres of streamflow.
Sprinkler roster compliance
The Winter Sprinkler Switch-off now applies, and our inspectors issued 83 warnings and 17 fines this week. Since 1 January 2018, we have taken a total of 5710 actions (warnings + fines) compared with 6814 actions for the same period in 2017.
Perth has received 580 mm of rainfall since January this year. According to updated figures released by the Bureau of Meteorology the cumulative mean rainfall (1994-2017) for the Perth metro for the January to December is 732.8 mm.
General water news
At this time of year we see many of the open stormwater drains that Water Corporation and councils manage start to fill up. It can be tempting, especially for children and dogs, to play in drains.
Now is a good time to remind everyone to keep away from drains as they can become dangerous. If a pet or child becomes caught in a drain it could cost them their life or endanger others who rescue them.
