The review of the Central Region Sustainable Water Strategy started in 2016, and it is the first sustainable water strategy to be reviewed. Sustainable water strategy (SWS) reviews The first regional SWS identify what was achieved, the lessons learned, where we currently are, the The CRSWS was Victoria’s first SWS.

Climate change recognised Aboriginal involvement in waterway The CRSWS was one of the first planning improved government water planning documents to implement the climate change policy The CRSWS formalised the engagement of direction in the Our Water Our Future Traditional Owner groups in water White Paper. It gave impetus to the planning and management, and it helped mandatory preparation of drought incorporate Aboriginal social, spiritual and response plans by water corporations and cultural objectives in strategies and plans CMAs and to low-inflow scenarios in including regional waterway strategies seasonal watering proposals.

All levels of water planning now consider potential climate It also laid the basis for Water for Victoria’s change impacts as a result of the Climate focus on recognising and managing for Change Act 2017, Victoria’s Climate Aboriginal values. Change Adaptation Plan 2017-2020 and other initiatives. Monitoring and reporting CRSWS actions resulted in better monitoring and reporting of waterway health, groundwater and water consumption. They improved water accounting, demand modelling and reporting. 4 Central Region Sustainable Water Strategy review report At a glance Department of Environment, Land, Water and Planning The CRSWS reduced demand for water Water-use efficiency is now Water conservation on a broad scale business-as-usual Other CRSWS successes include adoption CRSWS actions supported the locking-in of the 6-star standard by the Victorian of water-use efficiency measures, and Building Authority, trialling the water is used far more efficiently in the implementation of digital water meters, region than it was 20 years ago. The continuing the Schools Water Efficiency strategy, launched as Melbourne endured Program and extending the Pathways to record-low inflows and serious concerns Sustainability program for Melbourne’s about storage levels, offered positive, top-200 water users into the WaterMAP practical responses to the worsening program, which saved over 17 GL of water. drought. Consequently, demand for water fell by over 30% in 1997–2009 despite Melbourne adding some 500,000 people. On a per-person basis, Melbourne’s water consumption declined to levels not seen since the 1930s, and water managers were able to maintain supply throughout the Millennium Drought. Making the region more water-efficient CRSWS actions helped replace over 460,000 inefficient showerheads and over 4,500 inefficient toilets. Water restrictions and the Target 155 campaign had major behavioural change benefits. Between 2003 and July 2011, over 300,000 water-efficiency rebates were provided across Victoria, resulting in an estimated 1,758 ML a year of reduced demand for drinking water.
