Hard water in Normandie — 20-35°f hardness

In brief

  • • Normandie: typical hardness 20-35°f
  • • LIMPEO: scale reduction, works at any hardness

Water Hardness in Normandie

The Normandie region typically has a water hardness of 20–35°f (French degrees). This hardness is explained by the geology of the subsoil: chalk of the Pays de Caux.

The main cities affected: Rouen, Caen, Le Havre, Évreux.

To find the exact hardness for your municipality, visit qualite-eau.fr (French Ministry of Health portal) or consult our complete map of water hardness in France.

Impact of Limescale in Normandie

With a hardness of 20–35°f, water in Normandie is moderately to fairly hard. The consequences:

  • Scale deposits on pipes, water heaters and household appliances
  • Energy overconsumption of 7 to 25% depending on deposit thickness
  • White marks on taps and shower walls
  • Dry skin and dull hair
  • Reduced lifespan of appliances by 30 to 50%
