Eight Modern Drinking Water Treatment Plants Are Operated In Which The Water Obtained Is Processed Into Perfect Drinking Water. As Part Of The Weheüberleitung Project, An Approximately 5 Km Long Water Transfer Tunnel From The Hasselbach To The Wehebachtalsperre Is To Be Built In Cooperation With The Eifel-Rur Water Association (Wver). The Tunnel Begins On Jägerhausstrasse Above Zweifall, Where An Extraction Structure Is Planned In The Hasselbach, And Flows Into The Dam At The Root Of The Roter Wehebach Via An Inlet Structure. It Has A Gradient Of Around 0.25%. The Tunnel Should Transfer Up To 12 M³/S Of Water On A Free Gradient. From A Hydraulic Perspective, An Inner Diameter Of 2.8 M Would Be Sufficient For This. The Tunnel Is To Be Excavated Using A Tunnel Boring Machine. The Tunnel Construction Planning Currently Provides For An Internal Diameter Of 3.5 M - With The Exception Of The Zones Near The Portal. A Different Design By The Contractor Within An Inner Diameter Range Of 2.8 - 4.5 M Is Permitted. The Measure Is Expected To Begin In Mid-2027 And Is Expected To Be Completed By The End Of 2029.
