Hard water in Nouvelle-Aquitaine — 15-30°f hardness

In brief

  • • Nouvelle-Aquitaine: typical hardness 15-30°f
  • • LIMPEO: scale reduction, works at any hardness

Water Hardness in Nouvelle-Aquitaine

The Nouvelle-Aquitaine region typically has a water hardness of 15–30°f (French degrees). This hardness is explained by the geology of the subsoil: limestones of the Aquitaine basin.

The main cities affected: Bordeaux, Limoges, Poitiers, La Rochelle.

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.

Soft Water in Nouvelle-Aquitaine: Should You Still Protect Your Home?

With a hardness of 15–30°f, water in Nouvelle-Aquitaine is soft to moderately hard. Limescale is less problematic than in Île-de-France or the North, but:

  • Some municipalities may have harder water than the regional average
  • Soft water can be aggressive (negative Langelier index), promoting corrosion
  • LIMPEO also protects against micro-deposits that accumulate over the long term

The LIMPEO Solution for Nouvelle-Aquitaine

The LIMPEO, designed by MAGIIC SAS, works regardless of water hardness. It transforms calcite into aragonite through electromagnetic waves:

  • scale reduction — scientifically validated
  • 0 chemicals, 0 salt — water retains its minerals
  • 0 maintenance for a minimum of 10 years
  • 10-minute installation with no plumber required

Frequently asked questions

Is the water hard in Nouvelle-Aquitaine?
It depends on your municipality. The region shows a typical hardness of 15 to 30°f, meaning soft to moderately hard water, explained by the limestones of the Aquitaine basin. Some municipalities, however, exceed this regional average. For your precise address, check qualite-eau.fr.
Should you protect your home if the water is soft in Nouvelle-Aquitaine?
Yes, vigilance is still recommended. Even when soft, water can be aggressive (negative Langelier index) and promote corrosion. Micro-deposits also accumulate over the long term. LIMPEO protects your appliances against both phenomena, regardless of hardness.
Does LIMPEO work with water at 15-30°f?
Yes. LIMPEO transforms calcite into aragonite regardless of calcium concentration, so it also acts on relatively soft water like that in Nouvelle-Aquitaine. Designed by MAGIIC SAS, it protects your appliances over the long term, with no chemicals or salt.
