• Over the 91 days of summer, water use was below target for 63 days (nearly 70 per cent of the days throughout summer). This was a great effort by the community after the warmest spring on record which caused a spike in water use.
  • Over the 91 days of spring, water use was above target for 78 days (85 per cent of the days throughout spring).
  • Monday, 8 February 2016 was the hottest day throughout summer in Perth which led to the highest daily water use.  The temperature peaked at 42.5 degrees, with daily water use reaching 1.242 billion – or the equivalent of 552 Olympic sized swimming pools of water. 
  • With summer now behind us and temperatures decreasing in autumn, Water Corporation predicts daily water use should fall below 1 billion litres in mid-March.
  • While water use has been below target for most of summer, we have still used more than we should have this financial year. Water use remains nearly 4 billion litres above target (since 1 July 2015) which is enough water to fill about 1,778 Olympics swimming pools.
  • We’re asking households and businesses to help save water by reducing their sprinkler run times by two minutes per station through our Whatever you do, just drop 2 campaign.
  • Many people do not realise that over 40 per cent of water use in the home occurs outside in the garden. By reducing sprinkler run times by two minutes, a household can save around 480 litres of precious water each week.
  • Over summer we issued 2,183 infringements across the Perth metropolitan area - a 280 per cent increase from last summer. 
  • If you witness anyone breaching the sprinkler roster you can phone Water Corporation on 13 10 39. Property owners receive a fine if they are sighted breaching the sprinkler ban by an inspector, and a warning if they are reported by a member of the public, or if an inspector observes that sprinklers have been used.

How the drying climate affects water supplies

  • In 2015, Perth metro recorded its equal warmest year in 117 years of records - equal with 2011 and 2012.
  • Perth metro experienced its ninth-driest winter on record in 2015.
  • Warmest spring on record for most sites across Perth and driest spring in five years at Perth metro.
  • The drying climate resulted in record low inflows to Perth’s drinking water dams and the warmest spring on record caused unprecedented high water use. Perth’s dams received 11.4 billion litres of inflow in 2015 – the lowest inflows since records began in 1911.
  • Water use has returned to levels we would expect for this time over year over summer, however we are still nearly 4 billion litres above target since 1 July 2015.

*Note: This is water used by the Integrated Water Supply Scheme, which supplies water to Perth, Mandurah, the Goldfields and Agricultural Region and parts of the South West.
