The Future
 Building a New Social Contract
 Adapting to a Drier Future Climate
 Supporting Sustainable Growth
 Reducing the Environmental Footprint

20. November 24, 10 20
Strategic Directions
Building a New Social Contract
 Meeting future needs of
customers
 Fit for purpose products and
services
 Water market
 Third party access
Adapting to a Drier Future
Climate
 Being able to manage under
a range of climate scenarios
 Identify new sources of
water
Supporting Sustainable Growth
 Sale of growth water from
WMPP savings
 Intelligent operating systems
 Integrated approach to water
resource management
Reducing the Environmental
Footprint
 Development of GWMWater
energy projects
 Manage septic tanks as part
of the resource

21. November 24, 10 21
Sustainable Water &
Infrastructure
 The offer of drinking water for all
 Renewable energy
 The next source of water

22. November 24, 10 22
Drinking Water for All
 Many small “towns” or villages 10 – 100 people
 Cost of water treatment is not viable for small towns
 Various classes of towns, fully treated, disinfected only, raw water supply
 Lowest percentage of towns / customers supplied in Victoria
 WMP creates the opportunity of centralised treatment
 30 towns on main system – some already treated – many not
 Central treatment considered in business case
 Economics didnʼt stack up then
 Benefits for rural customers not clear
 Cost of treatment for water not needing to be treated
 Approaches / Options
 Central treatment – e.g. membrane – significant head available in parts of the
system
 Point of use – small towns / rural industry e.g. where export requirements
necessitate this
 Other?

23. November 24, 10 23
Renewable Energy
 WMP will triple GWMWaterʼs energy use – 40 000 MW hr
 WMP was Victoriaʼs first major water saving project
 Commenced before the focus on renewable energy
 GWMWater Board considers that “climate is our business”
 We should play our role in managing our impacts on climate as we are
critically dependent on climate
 Current Board has recently managed major capital project $680 M WMP
 Experienced in managing major capital investments
 Keen on the idea of owning own infrastructure
 Understands risk profile, e.g. compared to PPA
 Approaches / Options
 Regional scale - e.g. wind farm - 6-8 turbines, phasing
 Participation in joint schemes, e.g. solar
 Affordability
 Major issue for economic regulator Essential Services Commission

24. November 24, 10 24
Next Source of Water
 WMP and earlier NMP
 Saved 150 GL of water
 Recent climate sequence shows that these savings may not be enough under
some scenarios
 MDB Plan - will constrain further development of traditional sources
 Water Supply-Demand Strategy
 50 year plan for sources vs use
 Integration of other elements
 Septics
 Stormwater
 “New” pockets of groundwater
 Desalination
 Water savings - leakage, evaporation
 Demand management
 Water market
 Plenty of experience in many areas with these
 We will be seeking know-how to feed into this development
