Construction of the New Eiweiler Water Treatment Plant and Primstal Water Pressure Boosting Station

To ensure the supply of drinking water in the districts of St. Wendel and Birkenfeld, the Nonnweiler Dam Association (TVN) is planning to build a modern water treatment plant in Eiweiler and a supplementary pressure-boosting station in Primstal.

The Nonnweiler Dam, with a capacity of 20 million m³—the largest in Rhineland-Palatinate and the Saarland—supplies parts of the region with drinking and industrial water, helps maintain water levels during low-flow periods, provides flood protection, and generates hydroelectric power. The new treatment plant will have a capacity of 800 m³/h (5.2 million m³ annually). Existing pipelines totaling 10 km will be used to transport the raw water, and an additional 4 km of new supply lines will be laid. Since the site of the planned treatment plant is located approximately 70 meters above the dam, a high-capacity pressure-boosting station is being built in Primstal within an industrial park.

The project combines security of supply with sustainable water management.
