The Strategy Arrow
The essential
things that
we have to
get right
before we
can hope to
achieve our
Water availability and
Waste (re-use,
recycling, composting,
energy from waste)
Food and farming
Avoiding dangerous
climate change
Maintaining &
enhancing the
natural asset base
Land use
Marine environment
High Level Goals
High Impact Policies
Licence to Operate
Questions raised due to the drought
2004 - present
How effectively are we managing demand and
balancing it with environmental needs?
How well are we communicating with the public?
Do we have the right framework in place?
Key Water Outcomes
To improve water quality
and the ecology which it
To meet current and future water
demand, which is sustainable
Value for money and affordable
Climate change proofed - both mitigation and
Climate Change
UK climate impact scenarios predict an increase in
temperature, with wetter winters and drier summers
This will have multiple impacts on
water including:
Changes in the pattern, duration and frequency of
droughts and precipitation
Reduced water availability & environmental quality
Increased public demand
Climate Change, Energy and Water
Supply and treatment of drinking water and removal and treatment
of sewage used 8,100 GWh of energy in 2004/5
4.1 million tonnes of greenhouse gas
Predicted increase in water demand = more energy used
for abstraction, treatment, and supply and subsequently in
wastewater treatment and disposal
Additional household energy consumption due to personal water
Water Smart Homes and Businesses
Consumer education
Efficient water fittings
Rainwater harvesting and
Greywater reuse
Past Trends in Water Consumption
Environment Agency data shows household water consumption has
risen by 70% over the past 30 years mainly due to the introduction of
water demanding appliances.
Resource Management
Levels of water
Increase rate of metering in
areas of serious water stress
Serious water stress
Reduce leakage
Statutory 25 year water resource management plans
Water Strategy
A coherent, focused policy
framework which is resilient to
climate change
Better public appreciation of the value of water and the
consequences of wasting it
Water smart consumers, housing and industry
A water industry contributing fully to national energy and carbon
A water sector contributing to the maintenance and enhancement
of the natural asset base
Partnership Working
Series of Stakeholder
Engagement workshops on
key areas during spring
