📋 Tender Overview
The Ministry of Environment, Climate and Biodiversity, in collaboration with ALUSEAU - Luxembourg Association of Water Services - and the Water Management Administration, is launching this year the Wastewater - Wat leeft? campaign. This initiative aims to inform and raise awareness among the general public about the essential role of wastewater management in protecting the environment and water resources of the Grand Duchy. From March 2, 2026, a dedicated site (ofwaasser.lu) and a series of educational materials, communication and information tools will be distributed across the country in order to explain, in an accessible manner, the route of wastewater, the operation of sanitation networks and treatment plants, as well as the impact of daily actions on the quality of waterways and, ultimately, on drinking water. The campaign is financed by members of ALUSEAU (sanitation sector) and by the Ministry of the Environment, Climate and Biodiversity through the Environmental Protection Fund. Context Every day, wastewater from households, economic activities and public infrastructure is collected, transported and treated before being returned to the natural environment. Although Luxembourgs sanitation infrastructure is efficient, its proper functioning depends above all on the behavior of each individual. The campaign highlights this often invisible subject of everyday life and explains: how wastewater circulates in pipes, how sewage treatment plants work, how individual habits influence the quality of surface water and the protection of water resources. Improper use of the sanitation network can lead to obstructions, technical malfunctions, overloading of installations and increased pollution of aquatic environments. Raising public awareness of these issues is essential to guarantee sustainable water management in Luxembourg. Understanding the wastewater route The campaign emphasizes the need to better understand the wastewater route and the functioning of sanitation infrastructure. It aims to make visible a process that is often overlooked: what happens once the water disappears into the pipes, how it is transported, treated and finally returned to the natural environment. Through clear explanations and concrete examples, the campaign shows what can - and what should not - be discharged into the sanitation network. It shows that certain everyday behaviors, which may sometimes seem harmless, can nevertheless lead to obstructions, disrupt the operation of wastewater treatment plants or harm the quality of waterways. The objective is to raise public awareness of the importance of responsible actions and to emphasize that everyone has a role to play in the protection of water resources and the proper functioning of public infrastructure to support sustainable water management in Luxembourg.
