(100 year rains have occurred) Today Sweden invests 200 million Euro per year in renewal of the drainage systems A rough estimation is that the pace of renewal will grow 3 to 4 times during the next 25 years Is that probable, likely, feasible ? 7 Climate adaptation in Jönköping at lake Vättern Secure drinking water supply Renewal of pipes City regeneration projects Higher environmental requirements Growing City 88 Renewal strategy for piping systems • Step 1: Prioritize pipes • Step 2: Water flow directions and lowest points • Step 3: City-area based renewal Implementation: • Inventory • Responsibility division • Prioritize (very high, high, medium, low) • Response activity plans • Detailed planning • Realization Instead of just looking at the age of the pipes, also look at climate change impacts: 80% of system in need of renewal. Innovative renewal needed. 9 Yttre skyddsportar ska skydda Göteborg mot översvämningar och stigande havsnivå 10 FloodResilienCity Skydda Europeiska storstäder mot översvämning (17 M€, Interreg) Aim is to integrate • the increasing demand for more houses and other buildings with • the increasing need for more and better flood risk management measures • in North West European cities along rivers: France: Paris, Orléans Belgium: Brussels, Leuven Ireland: Dublin Great-Britain: Sheffield Germany: Mainz Netherlands: Nijmegen 11 Översvämnings riskhantering & hydromodellen När behöver man en hydromodell? • Awareness: To show flood risks (where, cost, frequency) and explain how to manage it • Avoidance: To limit flood damage and ease recovery by planning and adapting buildings, infrastructure, surfaces and economic activities and building capacity in individuals and institutions to become more resilient • Alleviation: To reduce flood risk by implementing physical, technical, non-structural and procedural measures for the management of water systems • Assistance: To provide support to for a quick recovery process by engaging and building capacity in communities, and others prior to, during and after flood events Hydromodell 12 Most recent plan for dike relocation Nijmegen When there is a flooding in your country … Who is responsible? Who will suffer? What will be the losses? What is your strategy? Where do you start? How fast can your region recover? Who will take measures that it will not happen again? Could it be prevented?
