On Friday 10 July 2026, Luxembourg’s Water Management Administration (AGE) announced the activation of a vigilance phase in response to the continued hot weather, below-average rainfall and rising drinking water consumption, and renewed the call for Luxembourg residents to conserve water.

The administration said the decision, taken in consultation with the country’s main drinking water suppliers, aims to preserve available water reserves and ensure the population’s drinking water supply in the coming weeks.

For several weeks, Luxembourg has experienced high temperatures and a lack of rainfall. This situation has led to a significant increase in drinking water consumption, and the administration advised that several suppliers are now facing increased pressure on drinking water supply infrastructure.

The activation of the national vigilance phase for drinking water supply is a preventive measure intended to avoid any further deterioration of the situation.

Reduce non-essential water use now

To preserve drinking water reserves, the AGE urges residents, businesses and local authorities to limit non-essential use of drinking water.

The move to the vigilance phase reinforces the appeal made during June to adopt everyday measures that reduce drinking water consumption. Everyone is encouraged to use water even more responsibly, particularly by avoiding watering lawns, limiting garden watering to what is strictly necessary and to the coolest times of the day, reducing the length of showers, repairing leaks promptly and using water-consuming household appliances only when they are fully loaded.

Preserving water resources for priority uses

The AGE stressed that drinking water is an essential resource and must, above all, be used to meet the population’s essential drinking water needs.

It said the efforts made by everyone help to reduce pressure on drinking water supply infrastructure and limit the risk of stricter restrictions being introduced if the current weather conditions continue.

Water suppliers mobilised

The AGE detailed that municipalities and drinking water syndicates are fully mobilised to monitor developments and implement the necessary measures at local level. Depending on how available water resources develop, some municipalities may introduce mandatory measures through municipal regulations. Residents are urged to follow the instructions issued by their municipality or risk a fine.

Protecting watercourses

The AGE highlighted that drought and high temperatures are also affecting watercourses, where water levels remain particularly low. To protect aquatic environments, the abstraction of water from rivers and surface water bodies throughout the Grand Duchy, with the exception of the Moselle and subject to any specific provisions laid down by ministerial orders, remains prohibited until further notice.
