As droughts, water scarcity and growing competition for water resources put increasing pressure on conventional water systems, the transition to a water circular economy is becoming more urgent. A new deliverable developed within the BOOST-IN project assesses the performance and uptake of Water Circular Economy Solutions (WACES) across Europe.
The assessment analysed 24 cases through questionnaires and interviews. The solutions were grouped into several categories, including monitoring systems, wastewater treatment processes- from primary to tertiary treatment with disinfection- management and training tools, and resource recovery approaches.
In parallel, a regional scan covering six regions of opportunity examined the main drivers, enabling factors and barriers affecting the adoption of these solutions.
The findings show that WACES support European policy objectives by improving water quality, enabling safe water reuse in agriculture and industry, and contributing to resource recovery. However, their uptake remains largely limited to pilot projects. Wider deployment continues to face challenges such as regulatory complexity, lengthy certification procedures, fragmented governance structures, high upfront investment costs and uncertain revenue models.
The deliverable identifies several conditions that can help accelerate implementation, including:
- Strong funding mechanisms and economic incentives
- Cross-sectoral cooperation between water, agriculture, industry and energy actors
- Simplified and harmonised permitting processes, investment in demonstration sites
- Increased public awareness and stakeholder engagement
Overall, the report concludes that a coherent policy framework, appropriate economic incentives and trust-building through transparent monitoring and stakeholder engagement are essential to scale up Water Circular Economy Solutions and strengthen Europe’s resilience to water-related challenges.
