Climate change induced hydrological risks are making central European cities increasingly vulnerable against urban floods and at the same time make the water scarcity problem worse. Coupled with growing drinking water consumption and consequently rising amounts of wastewater to be treated, this threatens the safety of future water supplies.

The CWC project aims to help municipalities to reform outdated urban water infrastructure systems via applying a circular economy approach, which offers many economic and environmental benefits. This will be achieved by the project by promoting a water saving culture, including the use of non-conventional water resources and by taking the lead in adopting urban rainwater harvesting and utilisation as well as greywater recovery measures on city level.

The partners join forces to create a knowledge base for urban circular water management. This will be made available as digital learning resources for all willing to learn more about the topic. The partners will also co-develop with local stakeholders a set of innovative methods and tools (cutting-edge technological and nature-based solutions, smart governance tools exploring novel cooperation and financing schemes) usable all around central Europe.

WATER LOSS

Water loss

Water loss occurs in every water distribution system during its overall lifetime and it causes not only additional operating costs but also has negative social and ecological impacts.
In urban areas, up to 70% of distributed water can be lost or never invoiced.
