Victorian Water Accounts 2018–2019 A statement of Victorian water resources Victorian Water Accounts 2018–19 1 Foreword The 2018–19 Victorian Water Accounts provide an overview of the use and management of Victoria’s water resources. In a time of more extreme weather events and extended periods of water scarcity, regular and comprehensive public water reporting has never been more important. Victoria continues to lead the way in such reporting. Victoria has developed online platforms to make monthly and annual reporting more easily accessible to the public. In 2018–19, conditions were again drier than in the previous year, with below-average rainfall across most of Victoria. Northern parts of the state experienced particularly dry conditions and large parts of East Gippsland continued to suffer from a severe multi-year drought, which affected large parts of eastern Australia. The decreased rainfall and hot conditions meant that there was less surface water available in 2018–19, compared to previous years. Consequently, there was an increase in the number of Victorian towns on water restrictions and an increase in restrictions on the volume that licensed landholders were allowed to divert from streams. The release of the Victorian Water Accounts 2018–19 marks the sixteenth in the series of annual reports. These accounts show the total volume of surface water, groundwater and recycled water available in 2018–19 was 12,073 GL, compared to 15,375 GL in the previous year. Victoria is in a good position to face the challenges of population growth, climate change and extended periods of drought and dry conditions, but we cannot be complacent. The Victorian Government, together with our partners, is leading the way in managing our water resources sustainably through Water for Victoria, our plan for responding to the pressures of climate change and population growth and for doing more with less water. This includes building the Victorian Water Grid with major pipeline extensions, irrigation modernisation, use of the desalination plant and investing in recycling, stormwater use and water efficiency. Together with the Victorian Water Accounts Highlights, released last year and available at https://howmuch.water.vic.gov.au/, we will soon be releasing an online version of the surface water accounts. These combined products will provide a new way to engage with water data and learn more about how water is managed. We are always looking to improve how we report, and if you have any suggestions about this please let the team know what you think by emailing us at [email protected].

  • Dams in Victoria Safe and Versatile Infrastructure
    Dams in Victoria Safe and versatile infrastructure A dam is a wall that holds back water to form a basin, lake or reservoir. Dams are typically made of earth, rock or concrete. Dams can be privately owned, owned by business or a Government agency. They can be used to store water for drinking, industry or farming, to protect property from flooding, or for recreation. Dams in Victoria Victoria has about 450,000 dams – this number shows how important dams are to the economy and our way of life. The sizes of our dams range from major storages such as Dartmouth dam (about 4,000,000 ML), Lake Eildon (about 3,300,000 ML) and the Thomson dam (about 1,070,000 Farm dams ML) to small swimming pool-sized dams on farms or lifestyle properties. These smaller privately-owned dams are the most Generating power: these large dams hold water for cooling common type of dam in Victoria. Together, Victoria’s dams have coal or gas-fired power stations or to generate hydro-electric a total storage capacity of about 13,400,000 ML. power. How we use our dams Recreation: some of the lakes created by dams are used for recreational activities such as boating and fishing.

This Deakin University project jointly with Griffith 15 University, for the National Centre of Excellence in Desalination (NCEDA), follows these new investments. We ask how best to manage bulk water supply and retail supply given the facts and fears of uncertain rainfall, modelled over a 100 year simulation period.

  • Water Supply Options for Melbourne
    Submission to the Environment and Natural Resources Committee Inquiry into Melbourne’s Water Supply Water supply options for Melbourne An examination of costs and availabilities of new water supply sources for Melbourne and other urban areas in Victoria Alan Moran Director, Deregulation Unit, Institute of Public Affairs Institute of Public Affairs Occassional Paper, revised August 2008 Water supply options for Melbourne Summary greenfield developments. Recycling Eastern Treatment Plant (ETP) water appears to be prohibitively costly, while Melbourne’s water supply is suffering from a combination releasing treated water and substituting it for other sources of drought and a failure to build new storage facilities over is also expensive. Some variations of household rainwater the past 23 years when the population has increased by tanks rival the Wonthaggi desalination plant proposal in over 30 per cent. These matters may be aggravated by providing the most expensive solutions.
