Our long term commitment to Melbourne's liveability

To understand the importance of water, you only need to look back to the ‘Millennium Drought’ that crippled Victoria between 1997 and 2009, which dramatically changed how Victorian government, business and residents now manage the state’s water supply.

22 March 2016

As a Federal Government Productivity Commission report declared in 2011, water must be treated differently to other utilities such as gas, electricity or telecommunications because it is literally ‘essential for life’.

The health of Melbourne, as a major city, is intrinsically connected to water.

The ability of the city’s industry to thrive and expand needs an uninterrupted water supply. Outside the metropolis, the need for agriculture to access water is obvious. Community facilities and social life can wither and die without water, and that has been proven to have a substantial impact, economically as well as physically. 

We are aware that Melbourne’s residents - who use two thirds of our supply - community organisations and local businesses, cannot afford to endure the level of water restrictions demanded by the Millennium Drought.

During the most urgent water restrictions of the Millennium Drought, when water could no longer be allocated for maintaining community infrastructure such as sports fields, some estimates costed the damage to ‘welfare in the community’ of no longer having such communal outdoor recreation facilities as between $400 million and $1500 million. Now consider the potential financial cost of water restrictions to individual households or businesses or, for that matter, the medical bills of Victorians who hurt their back lugging buckets of water from their shower to their dying flowerbeds. A major drought cripples a metropolis like Melbourne and a State like Victoria, on every level.

From hygiene to hydration to food crops to grassy fields to the leaves on trees: water is the link that keeps society going.

We have always maintained a long-term view of Melbourne’s water needs and our role in supplying this most precious commodity. We are an enthusiastic signatory to the United Nations’ Global Compact and we are currently investigating how we can align how we operate more closely with the Sustainable Development Goals. 

Locally, we collaboratively plan for the city’s water future - towards 2060 and beyond. We are aware that Melbourne’s residents - who use two thirds of our supply - community organisations and local businesses, cannot afford to endure the level of water restrictions demanded by the Millennium Drought.

The good news is that we’re confident we have many of the answers.

In the past, business water needs, sprinklers on sporting grounds, firefighting water, the water that filled every toilet cistern and the drinking water in every tap in every house came from the same fresh, pure water source, direct from our potentially over-stretched dams. But this does not have to be the case and increasingly is not. Integrated water cycle management now includes the harnessing of the city’s sewage and storm waters, previously regarded as unclean and removed from the city as quickly and discreetly as possible. 

However, with the appropriate level of treatment, these rich resources can be harnessed for the myriad of water needs that do not require the sheer purity of Melbourne’s drinking water. Given it is estimated that the city generates around 540 GL a year of excess water through stormwater runoff alone, the benefits of capturing and reusing that water are obvious.

These realisations have driven the evolution of the city’s water supply, with investment on all levels, from household rainwater tanks to transfer pipelines, and major new stormwater and sewerage infrastructure that is dedicated to rehabilitating and reusing these waters, rather than flushing it away.

Businesses make a positive contribute to sustainable water use.

The state’s business community has bought in, dramatically dropping the overall use of water for industry (reducing usage from 138 GL (Gigalitres) in 2000/01 to 89 GL in 2010/11) and getting smarter. As an example, the proliferation of commercial car washes across the city could not have survived the drought or beyond had they not crafted a way to use recycled waste water/non-drinking water.

We are committed to providing our water services within the carrying capacity of nature. And we are committed to helping create better places for people to live. We have committed to supplying recycled water to around 100,000 homes or approximately 200,000 people in the northern growth area. 

Victoria’s desalination plant is operational and ready to transform salt water to combat future climate change effects or major droughts, while Melbourne’s metropolitan water utilities are innovating to reduce or eliminate reliance on dams for the water needs of the city’s community spaces. 

Melbourne is transforming from a city reliant on its dams to a city with a healthy, rich future, from lush sports grounds and community resources to kitchen taps that deliver the pure drinking water we love.
