qualité-eau.lu is an independent information portal dedicated to the quality of tap water in the Grand Duchy of Luxembourg.
Our mission: to make the official public data of the Administration de la gestion de l'eau accessible to all residents, in French, German and English, municipality by municipality.
We cross-reference the official datasets (water hardness, Drëpsi certification, nitrate-vulnerable zones) to produce a readable Water Score and concrete recommendations to improve the quality of your water at home.
For equipment recommendations (water softeners, reverse osmosis systems), we work with two Luxembourg partners: adoucisseur-eau.lu and osmoseur.lu. This collaboration is transparent, disclosed at every CTA, and does not influence how the data is presented.
