PREPARED - Catalogue of European adaptive initiatives of the water sector to face climate change impacts D1.1.1

Adaptation to climate change, though not always percieved as such, is often already reality in the urban water sector. Several adaptation strategies have been tested to address the key questions: Adapt to what? What to adapt? How to adapt? In this context, within the framework of the EU-project PREPARED, a tentative classification and catalogue of implemented initiatives in the water sector has been compiled. This catalogue is organized into four categories of initiatives: 1, risk assessment and management, 2, supply-size measures, 3, demand-side measures and 4, global planning tools. The document aims at providing examples on how utilities could go ahead into preparing their water supply and sanitation systems to climate change. Initiatives include various measures ranging from the promotion of active learning to the prevention of sewer flooding and water conservation measures. It is a living document and thus updated regularly along the project when new solutions and initiatives are known. In addition, this work and the subsequent database of adaptation initiatives are accessible to a broader audience thanks to the web-based 'WaterWiki' of the International Water Association (IWA).
