Dunea: expert in dunes and water
Dunea stands for drinking water and nature conservancy
Dunea produces and distributes tap water of a drinking water quality that ranks amongst the best in the world. We supply 24 hours a day and with the least possible leakage and service disruption. The Solleveld, Meijendel and Berkheide dunes are crucial for the purification proces. Furthermore, this function also helps conserve very unique and valuable habitats with one of the the largest biodiversity counts in the Netherlands.
Drinking water
Producing good and reliable drinking water in harmony with nature. That is what Dunea is committed to every day. Over 1.3 million people in the western part of South Holland can count on Dunea tapwater 24 hours a day. What does drinking water consist of? And what is the hardness of the water? Dutch drinking water is among the best in the world because it is purified so well. That doesn’t mean it holds no other substances. Drinking water contains minerals, salts, good bacteria etc.
Smart water use
The Freshman project
In coastal dunes, it is quite common to find brackish groundwater at greater depth in the soil profile. The origin of brackish groundwater is mixing of rainwater percolating from above, and seawater which intrudes into the aquifer. Can we use this brackish water as a new source for drinking water? And what would be the effect of abstracting brackish groundwater on the large freshwater stock that is present in the coastal dunes of The Hague? Could we even increase our freshwater storage in the dunes by extracting brackish groundwater?” These are the questions we are addressing in the Freshman project, a five-years research project co-financed by the EU LIFE Programme.“Producing good and reliable drinking water in harmony with nature. That is what Dunea is committed to every day.”
