1 PREPARED - Enabling Change Environment Programme - Call FP7-ENV ENV Adaptation of water supply and sanitation systems to cope with climate change Adaptation to climate change : 'Adjustment in natural or human systems in response to actual or expected climatic stimuli or their effects, which moderates harm or exploits beneficial opportunities.' (IPCC, 2007).

2 Observed annual average temperature UNECE Europe Source: Europe s environment: the fourth assessment Observation: Climate is changing 1.4 C increase in the annual average temperature (compared with preindustrial levels in EU) Europe is likely to warm C by 2080, or possibly Temperature deviation, compared to average ( C)

Units are in mm relative to the average for 1961 to Error bars are 90% confi dence intervals.

11 Identified impacts of climate change either expected or already observed for water supply and sanitation systems Water supply: Surface water availability Change in run-off patterns and surface water quality Groundwater availability (decreased natural recharge) Saline intrusion in groundwater in coastal area Changing demand patterns, land use (temperature, crop) Flooding of well field Biogrowth in distribution network Treatment efficiency (e.g. MAR systems) Sanitation extreme precipitation (sustainable drainage, CSO, increased storage, WWTP) Salt water intrusion Vernagt glacier (Austria) lost more than 50% of mass between 1912 and 2003, Source: Global Outlook for Ice and Snow, UNEP, 2007
