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The City Water Circles - CWC project aims to help municipalities to reform outdated urban water infrastructure systems via applying a circular economy approach, which offers many economic and environmental benefits. The outputs of the project will help European cities to implement water management on their territory. 


Model strategies and pilot investments have been developed, and the knowledge base supporting professional and decision-making activities will make the technologies, financial and policy tools that can be applied in cities freely available to all stakeholders.

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.
