The water extraction and treatment company Nordeifel mbH , short WAG Nordeifel, is a water supplier based in Roetgen in the northern Eifel. It is a joint subsidiary of the municipal energy and water supply companies enwor and STAWAG of the Aachen city region , whose shares each amount to 50%.
The water extracted and treated by WAG Nordeifel from wells and reservoirs is fed into the drinking water networks of the two parent companies, which are then responsible for further distribution to the customer. A smaller part of the drinking water is made available to the utilities Energie- und Wasserversorgung (EWV) and Waterleiding Maatschappij Limburg (WML), if necessary also to the water supply association Perlenbach and Stadtwerke Düren (SWD). Thus, in addition to the city of Aachen and the city region of Aachen ( Alsdorf , Baesweiler , Eschweiler , Herzogenrath , Stolberg , Würselen ), WAG Nordeifel also supplies part of the district of Heinsberg ( Übach-Palenberg ) and the Dutch cities of Vaals and Kerkrade with drinking water. That corresponds to about 600,000 inhabitants.
Apart from the two managing directors, WAG Nordeifel has no direct employees, as the two parent companies act as personnel service providers . WAG Nordeifel, on the other hand, is a service provider for the parent companies by providing the appropriate quantities of treated drinking water.
Waterworks and dams
WAG Nordeifel draws a large part of the drinking water made available from the Dreilägerbachtalsperre it operates and the Kalltalsperre , which is fed by the tributary of the Dreilägerbach , a transfer from the Kalltalsperre and a transfer from the Obersee .
In the attached drinking water treatment plant (TWA) Roetgen, the raw water taken from the barrier is treated accordingly on site. In 2006, enwor invested in an ultrafiltration system that replaces the usual sedimentation stage and represents one of the most advanced treatment technologies in Germany. On average, 2,500,000 m³ of drinking water were treated here per month in 2018. That corresponds to over 83 million liters per day.
Another source of supply is the Wehebachtalsperre dam , which is operated by WVER. In 2018, around 570,000 m³ of raw water per month were treated in the TWA in Schevenhütte .
A number of groundwater works are also used to obtain water, which make up around 15% of the total amount of drinking water distributed: The works in Binsfeldhammer (Stolberg), Hastenrath (Eschweiler), Hitfeld (Aachen-Brand), Schmithof (Kornelimünster / Wahlheim), Brandenburg and Reichswald (Verlautenheide) bring mineral-rich groundwater to the surface and thus mainly supply parts of Stolberg, Eschweiler and Aachen with harder drinking water.
Company laboratory
WAG has its own company laboratory, which ensures the quality of the drinking water at the factory exit through daily tests. In addition, random samples are regularly examined in the supply networks of the parent companies in order to ensure compliance with the requirements of the Drinking Water Ordinance through to the consumer.
Others
WAG Nordeifel is a partner in the ENERWA joint project, which deals with the energetic optimization of water extraction, treatment and distribution.
