Description
The main scope of the construction work is the drilling and extension work for 11 drinking water wells. The wells are to be drilled using the cased dry drilling method with a drilling diameter of DN 900 and DN 1200. The maximum final depth of the wells is around 30 m. The wells will be constructed using stainless steel full and filter pipes (DN 400 and DN 600) with double-shell filter gravel packs (bulk piping DN 600 and DN 900). During the annular space filling in the filter area a bulk material consolidation (as an own contribution of the AG) is carried out. Finally, 8-hour clear pumping tests (4-stage) are to be carried out at each well and the dismantling of the old wells is also part of the construction work. The old wells are to be filled with filter gravel and spring clay.
