Treatment of surface water
For the exploitation of surface water resources, we have 9 production centres, each equipped with a treatment plant.

For the exploitation of surface water resources, we have 9 production centres, each equipped with a treatment plant.
When it comes to water treatment, we have developed cutting-edge know-how, using the most advanced techniques such as nanofiltration, which was implemented at the Gaurain-Ramecroix plant in 2002, and then at the Stembert and Eupen plants in 2009. We were the first Belgian company to use this process.
In operation since 2002, the Gaurain-Ramecroix (also known as Transhennuyère) production centre pumps and treats water from several surrounding quarries.
Processing capacity: 40,800 m³/day.
High-pressure pumps send the treated water to municipalities in Western Hainaut and Flanders.
The water is drawn from the nearby Restaumont quarry.
Processing capacity: 28,800 m³/day.
The water produced supplies the municipality of Ecaussines, the Feluy industrial estate, an important industrial player in the region, and several municipalities in West Flanders.
The facilities have been modernised and meet European standards. The plant treats water from the Vesdre dam.
Processing capacity: 65,000 m³/day.
It supplies drinking water to the municipality of Eupen and to the municipalities in the northern part of the Herve region.
Like the Eupen plant, it boasts upgraded facilities that meet European standards.
Processing capacity: 45,000 m³/day.
The plant serves the Verviers and Stavelot regions.
The plant is fed by water from the Nisramont dam.
Processing capacity: 24,000 m³/day.
The Nisramont dam complex serves the municipalities of Marche and the north of the province of Luxembourg, as well as the plateau of Bastogne (up to Martelange).
