Water from Victoria’s Desalination Plant has begun to flow into Melbourne’s storages, securing our water supply and helping to avoid harsh restrictions.
Minister for Water Lisa Neville said the largest ever order of 125 GL would start to reach Cardinia Reservoir from today and be delivered progressively over the next year.
This additional water will contribute 6.9 per cent to Melbourne’s storages – which would be a further 4.2 per cent lower today without the desalinated water delivered over recent years.
Even with recent rainfall, Melbourne’s water storage levels currently sit at 49.8 per cent, 8.3 per cent lower than same time in 2018 and close to their lowest level since 2011, after the Millennium Drought severely impacted our water storages.
These low levels are a result of below average inflows into Melbourne storages in 18 out of the past 20 years, combined with higher than normal temperatures and huge population growth of 1.4 million in Melbourne since 2001.
The Bureau of Meteorology’s latest three-month seasonal climate outlook predicts the above average autumn temperatures and below average rainfall are set to continue. Given Melbourne’s water demand has outstripped supply in recent years – it shows why the desalinated water order is crucial to providing water certainty.
Only metropolitan Melbourne customers pay for the desalination order and this cost is subsidised as much as possible. This year’s order is expected to add an average of around $10 per household for the year. Even with the desalination order for 2019-20, Melbourne’s bills remain the lowest of any capital in Australia.
Melbournians can also do their part by adopting water efficiency measures at home to help reduce demand and make sure they’re following the Permanent Water Saving Rules when it comes to using water in the garden or outside the house.
Our average annual daily use is around 161 litres per day but by making a few small changes, such as shorter showers or turning the tap off while brushing your teeth, we can reach our target of 155 litres per day.
These simple tips, along with the desalinated water order, will help mitigate the need for harsher water restrictions and ensure we have enough water supply to meet our needs into the future.
While the State Government issued the above Press Release they have failed to add that the Upper Yarra Dam (Melbourne's third largest)has been kept low due to the danger of the dam wall failing and causing a catastrophic flood in the suburbs of Melbourne. Work on the dam begins in September and won't be complete until 2021.
