The primary objective of DEMOWARE was to address the challenges of water stress in Europe, low public confidence, and fragmented approaches to water reuse. This was achieved through a highly collaborative programme focused on demonstration and exploitation, leveraging nine existing demonstration sites and one greenfield site. These sites encompassed agricultural, urban, and industrial applications of water reuse, aiming to stimulate innovation and foster greater cohesion within the developing European water reuse sector.

The specific objectives of the project:
• To demonstrate the technical feasibility of innovative technologies for wastewater reclamation and reuse.
• To showcase advanced monitoring and control systems that ensure the targeted removal or management of water constituents—such as pathogens, contaminants, and nutrients—across diverse water recycling schemes.
• To demonstrate how effective risk assessment and management of environmental and human health can maximize the socio-economic and ecological benefits of water reuse, while minimizing negative impacts.
• To enhance and promote the marketability of water reuse solutions.
• To strengthen the capacity of reuse scheme operators to implement socially acceptable projects within collaborative and efficient governance frameworks.
• To raise awareness and improve understanding of water reuse practices among public authorities and end-users.
• To develop a distinct identity and knowledge base for the emerging European water reuse sector, including the establishment of a European Water Reuse Association.
