The drinking water route between L’Hôpital and Freyming-Merlebach

What are the issues related to the preservation of drinking water resources and the fragility of biodiversity? Let’s follow our guides: Philippe Rouget, the director of the Winborn mixed water union and Mickaël Charpentier, water specialist engineer for SEE/SUEZ

“Although invisible, groundwater plays a major role for humans and the environment.. They contribute to the supply of watercourses, and allow the maintenance of aquatic life. Thanks to their quality and the natural stock they constitute, they are also the main source of drinking water supply in France, and are used in agriculture and industry.

“A water table is an underground water reserve located at shallow depth. In general, these aquifers are neither lakes nor underground streams: they are water contained in the pores or cracks of the rocks, saturated by the rainwater which has infiltrated”.

In the east of France

The water tables are found in a layer of sandstone, called Lower Triassic (GTI), which plunges down to around 200 meters.

The water stored in the groundwater comes from the Vosges mountains and extends to Luxembourg, Belgium and eastern France.. The water progresses a few centimeters per year in the Vosges to take on minerals and purify itself.

Between the Hospital and Freming-Merlebach

14 boreholes in operation for water distribution via 90,000 people to different municipalities. To obtain quality water, a whole team of engineers and technicians work in the field and at the Winborn water production plant. You will understand how a water tower works, that of the Hospital where everything happens about forty meters away with a reserve of water then distributed to the various municipalities.
