Orange

Several municipalities have declared an orange alert and imposed drinking water restrictions with immediate effect. Waldbillig and Bertrange are among the first, and other municipalities have followed suit. The restrictions ban a list of water uses that, taken together, describe a normal summer weekend in Luxembourg.[1]

Until further notice, individuals are prohibited from washing their cars, cleaning pavements and facades with a hose, filling or topping up private swimming pools and ponds, using jet cleaners or high-pressure cleaners, running fountains unless they use a closed water circuit, cooling food and drinks under running water, and watering green spaces, parks, cemeteries, and sports fields. Newly planted areas are exempt. Fines range from €25 to €250.[1]

From yellow to orange

The Meteolux heat alert has been yellow for five consecutive days. The drinking water alert is now orange. Yellow means moderate heat stress. Orange means the situation is serious enough to restrict access to a resource that people normally use without thinking about it. The escalation from advisory to prohibition happened in the space of a week.[1]

Last week, municipalities imposed water restrictions with fines of €25 to €250. The difference is that those were preventive measures. The orange alert is a reactive one. Drinking water is becoming increasingly scarce. The statement from the municipalities says so explicitly. The water supply to the playground at the Heringer Millen in the Mullerthal region has been cut off until restrictions are lifted.[1]

The list

The list of prohibitions is worth reading in full because it describes, by negation, what normal life looks like. Washing a car. Cleaning a pavement. Filling a paddling pool. Running a fountain. Cooling drinks under running water. Watering a park. Each of these activities uses water in a way that feels trivial. Together, in a drought, they use enough water to threaten the supply.[1]

The heatwave cascade started with discomfort, moved to infrastructure, reached the ecosystem, and has now arrived at the tap. Five days of yellow alert produced an orange alert. The question is what six days would have produced, and whether the orange alert will be enough.[1]
