Metro weekly water update 21 June 2018

Note: 1 billion litres = approx. 400 Olympic swimming pools.  Please note these figures are rounded (except for rainfall) to the nearest whole number.

Water use

Average daily water use over the last week was 630 million litres, which was slightly above the forecast of 609 million litres.  Since 1 July 2017 we have used 280 billion litres of water, which is 7 billion litres below the 287 billion litres we had forecast.

Dam levels

Over the last seven days, Perth’s dam storage levels have increased (by about 3 billion litres) from 143 billion litres to 145 billion litres of usable storage. Perth’s dams store water from three different sources… groundwater and desalinated seawater transferred from treatment plants as well as streamflow (produced by rainfall).

Sprinkler roster compliance

The Winter sprinkler roster now applies, and our inspectors issued 232 warnings and 31 fines last week.  Since 1 January 2018 we have taken a total of 4523 actions (warnings + fines) compared with 5399 actions for the same period in 2017.

Annual rainfall

Perth has received 295.2mm of rainfall since January this year.  According to updated figures released by the Bureau of Meteorology the cumulative mean rainfall for the Perth metro is 303.5mm (1994-2017).

Planning Perth’s water supplies for the long-term

In October 2009 we released Water Forever: Towards Climate Resilience our 50-year plan to deliver sustainable water and wastewater services to Perth and surrounding areas.

Water Forever was developed with input from the community and businesses to ensure it reflected their views and preferences for securing our water future.

As you can imagine our plan for securing Perth’s water future is quite detailed – it has over 100 pages of information - but if you only have time for the headlines – we have an eight page summary available. 

Why not give the summary a read and impress your mates about your water knowledge at your next BBQ!
