Cut And Fill – Expansion Of The Groundwater Measuring Point Network In The Area Of ​​The Scheidhof Catchment Facility: Construction Of 5 New Groundwater Measuring Points In The Central Area Of ​​The Wga Scheidhof. The Construction Of 5 New Groundwater Measuring Points In The Area Of ​​The Scheidhof Collection System In Full Service. There Are 3 Locations In The Area Of ​​The Luxembourg Sandstone Covered With The Layers Of The Middle Lias And The Lower Lias (Measuring Points 1, 3 And 4). Due To The Great Thickness Of The Cover Layers, These Measuring Point Structures Require Drilling Depths Of 100 To 130 M And Then Tap Into The Tense Pressurized Water Level Of The Target Horizon. At Locations 2 And 5 In Luxembourg Bonnevoie (Location 2) And In Sandweiler (Location 5), The Luxembourg Sandstone Is Under Thin Cover Layers, So That The Measuring Point Drillings Must Reach The Unconfined Groundwater Table In The Target Horizon At Each Location And Require Drilling Depths Of 45 To 60M.
