Europe faces rising long-term dangers as flooding, water shortage and air pollution more and more converge throughout the continent, in response to a brand new evaluation from engineering and structure consultancy Sweco.
The report, An excessive amount of, too little, too polluted, warns that climate-driven climate extremes, ageing infrastructure and declining water high quality are creating prices and vulnerabilities that aren’t absolutely mirrored in present pricing methods or funding selections.
Drawing on European knowledge and Sweco’s engineering and architectural evaluation, the report states that round 20% of Europe’s land and 30% of its inhabitants expertise water stress annually. Flooding prompted an estimated €18 billion in harm throughout 2024 and affected greater than 400,000 individuals.
On the similar time, 32% of groundwater our bodies are underneath stress from diffuse air pollution, primarily linked to agriculture, whereas prescribed drugs and PFAS “endlessly chemical compounds” are actually being detected in most European water our bodies.
In line with the report, the challenges of flooding, water shortage and air pollution can not be handled individually.
“Europe’s water problem not issues remoted occasions or particular person areas. Sweco’s evaluation reveals that flooding, shortage and air pollution should be managed as one interconnected system, or the dangers will proceed to develop and threaten Europe’s water safety, public well being, infrastructure reliability and financial stability,” mentioned Mattias Salomonsson, Water Skilled at Sweco.
The report additionally highlights issues over ageing infrastructure and underinvestment in water methods throughout Europe. Sweco mentioned a lot of the continent’s water infrastructure was designed a long time in the past for various weather conditions and decrease therapy calls for. In lots of international locations, round 20% of handled water is misplaced by means of leakage.
Utilizing pricing knowledge and technical price modelling, Sweco estimated that introducing superior therapy to take away micropollutants would improve common water prices by round 6%, with the most important impacts anticipated in international locations the place water costs are at the moment comparatively low, together with Sweden, Eire and the Netherlands.
The consultancy argues that the long-term prices related to flooding, provide disruption, tighter regulation and environmental degradation should not adequately mirrored in present water pricing or infrastructure funding methods.
“The true price of water extends far past the water invoice. Failure to think about future flood harm, provide disruptions, stricter regulation and environmental degradation at an early stage implies that dangers and prices improve over time. Nonetheless, options do exist and throughout Europe, Sweco is supporting private and non-private purchasers in strengthening water methods by means of long-term planning, risk-based investments and built-in approaches that improve resilience,” mentioned Salomonsson.
The report identifies six precedence actions for governments, municipalities, utilities, traders and insurers, together with necessary water threat assessments, long-term municipal water methods, renewal of ageing infrastructure, resilience-based utility operations, integrating water threat into funding and insurance coverage selections, and better use of nature-based options in land-use planning.
Sweco mentioned examples of those approaches are already being applied in a number of European international locations, together with superior wastewater therapy tasks in Germany and Belgium, climate-adapted city areas in Denmark, round rainwater storage methods within the Netherlands, drought resilience planning on Jersey, and dam security and flood reassessment work in Norway.
