Climate Change Adaptation Strategy
System
Performance
Performance declines over time due to external
influences and asset deteoriation
Knowledge about
Climate Change
Performance standard
Incremental adaptation responses
Large investment in
infrastructure
More rapid change in external
drivers than anticipated will after a
few years result in more rapid
decline in performance

Expansion of Water Safety Planning approach
Water cycle level allows integration of
different stakeholders views and collaborative
actions
Common risk approach and risk criteria
facilitates comparison of different risks
Generic tools to facilitate risk process are key
to ensure adequate application and increase
trust in the results
Adaptation at different decision levels
(operators, managers) improves effectiveness

SIMDEUM improves the quality of
(drinking water) network models
Improved network models lead to a
better understanding of e.g. flows and
water quality in networks
This improves the understanding and
interpretation of sensor measurements
Better understanding of water flows and
processes in networks helps to optimize
(necessary) investments costs in networks

Planning for resilient water supply
Integrated Water Resource Management promotes
• water resources allocation
• better planning for more resilient water supply and
sanitation systems
• safety against flooding
• reliability of water supply during extreme hydrologic
events
and stimulates economic development

Towards new design concepts
Regions under water stress need to
consider:
• New design concepts (e.g. flood proof
well fields)
• New (additional) water resources
• Adaptive Water Sensitive Cities
Breakthrough sector-wise approach
(drinking water supply, waste water and
stormwater management)

Interruption of power supply,
assets out of business
Leakage through infrastructure

Risks for microbial infection of
raw water and introduction of
chemical substances
Increased concentrations of
chemical substances in raw water
Need for backup water supply

Climate proofing of European Water directives
• GWD implementation in MS can cause barriers to MAR & dune infiltration for
subsurface water storage and water quality improvement.
• WFD pricing policy for water in some MS will cause barrier to sustainable water use
(selling price lower than production cost).
• DWD inclusion of RA/RM concept would boost WCSP approach.
• UWWTD and BWD drivers behind investments urban water cycle; Stricter national
standards will increase investment needs (CSO).
• BWD allows the use of EWS for overflows in receiving waters.
• Infiltration of residual waste concentrate from desalination in the subsurface.
