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?

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

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
