Seneffe is a Francophone commune of roughly 11,000 residents in central Hainaut, Wallonia, on the Brussels–Charleroi canal. At a summer municipal council (conseil communal) meeting reported by La Dernière Heure, storms and flood risk were central and the administration signalled it would accelerate prevention projects. Flood policy in Wallonia is shared between communes, the intercommunale managing water and sewerage, and the Service public de Wallonie (SPW), which maintains flood-hazard mapping at inondations.wallonie.be. The federal BE-Alert system delivers emergency warnings and the Royal Meteorological Institute (RMI/IRM) issues storm alerts.
Background
The July 2021 floods in the Vesdre and Meuse valleys killed 39 people and ranked as modern Belgium's deadliest natural disaster, prompting a regional overhaul of flood-risk mapping and river-management plans and leaving Walloon mayors under lasting pressure to demonstrate preparedness.
What to do
Residents should: check their address at inondations.wallonie.be; register at be-alert.be for SMS/voice warnings; monitor RMI (meteo.be) storm colour codes; photograph and document ground-floor contents for insurance; consider a drain non-return valve; and ask the commune (in French) about nearby retention capacity and égouttage plans.
Impact
Regional — Directly relevant to Seneffe residents and, by extension, to homeowners across Hainaut and Wallonia weighing flood exposure, insurance and drainage. The commune's willingness to prioritise prevention publicly reflects a wider post-2021 shift in Walloon local government toward visible, pre-emptive flood management.
