The Brussels-Capital Region activated the vigilance stage of its drought framework on 23 July, the day after its water coordination platform met. The platform is led by Brussels Environment and includes the water utility Vivaqua, the Port of Brussels and Safe Brussels, and it acted on forecasts showing no significant rainfall for the following ten days, with conditions across the country moving from dry towards very dry.
At this stage the measures are requests rather than rules. Residents are asked to stop washing cars, filling swimming pools, hosing down surfaces and watering lawns and plants. The existing ban on lighting fires in forests and regional green spaces stays in force, and the wildfire risk was rated at the second highest level.
Two of the indicators are worth more attention than the hosepipe list. Levels in the region's non-navigable watercourses are falling without yet being critical, which is the metric that decides whether ecological damage becomes permanent. And cyanobacteria are proliferating in some regional ponds, which is a public health matter as much as an ecological one, because it closes water to dogs and children rather than to boats.
The Port of Brussels response is the most instructive measure on the list, and the easiest to misread as a leisure restriction. It consolidated lock operations and limited recreational boating. Every time a lock cycles it sends a volume of water downstream, so grouping vessels into fewer lockages is not crowd management. It is a water budget decision, taken at the only point in the system where a regional authority can meaningfully turn a tap.
What is new here is not the dry spell. It is the machinery: a standing task force with a named lead, a staged alert scale, and a scheduled review date rather than an open ended appeal. Belgium spent most of a century engineering its water policy around having too much water. The institutions for the opposite problem are recent, and this is what they look like when they run.
