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The City Water Circles - CWC project aims to help municipalities to reform outdated urban water infrastructure systems via applying a circular economy approach, which offers many economic and environmental benefits.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.
CWC PILOT ACTIONS
BYDGOSZCZ PILOT ACTION
Rain is profit - Bydgoszcz boasts a rain garden
New green and blue infrastructure was created in Bydgoszcz, a rain garden next to the historic palace of the Waterworks Museum.

SPLIT PILOT ACTION
Real time monitoring of water consumption in Split
Real-time water consumption monitoring with wireless tools at three different points in the University of Split, Faculty of Civil engineering, Architecture and Geodesy.
TURIN PILOT ACTION
Rainwater recovery rooftop garden and aeroponic greenhouse in Turin
"Meet water, meet people, meet plants" The pilot action demonstrates rainwater retention by nature-based solutions.
MARIBOR PILOT ACTION
Secondary raw material from rain and wastewater in Maribor
The pilot action demonstrates the potential of using treated wastewater and rainwater to produce secondary raw materials (SRM) based construction products.

SMART WATER GOVERNANCE
Smart Water Governance is the innovative approach to the circular management of water resources.
Active involvement and engagement of the stakeholders and to make a good use of technological tools are core elements in SWG.
DIGITAL LEARNING RESOURCES
GREY WATER
Greywater is all wastewater that is discharged from a house, excluding blackwater (toilet water).
Can we reuse it? Does it save money for households and institutes? What are technical and hygenic requirements of reuse?

RAINWATER HARVESTING
Harvesting rainwater for saving drinking water has gained enormously in significance as a modern water saving sanitary technique.
Digital learning resources
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.
Digital learning resources
WATER EFFICIENCY
Water efficiency is the reduced use of water possibly in all water consuming activities and sectors without comfort or functionality loss. It leads to significant savings in water and energy and to less wastewater production.

STATUS QUO OF 5 FUA
The CWC FUAs performed self-assessments about their background conditions related to circular water use. The assessment consists in 44 indicators that provide information, by means of charts, maps or tables.
DIGITAL LEARNING RESOURCES
WATER FOORPRINT
We consume water from our tap for many domestic uses, but also our purchases and habits influence our overall water consumption.
