Driven by increasing environmental pressures and climate challenges, the water sector is undergoing a major transformation in Wallonia. Ensuring water availability in both quality and quantity, while addressing floods, droughts and ecosystem preservation, is essential for public health, economic activities and environmental sustainability. This requires coordinated action across technologies, infrastructure and resource management, including drinking water production, wastewater treatment and reuse, and the protection of natural systems.

The water value chain spans natural resources, production, storage, distribution, treatment and uses, supported by transversal activities that enable innovation, governance and knowledge sharing.
