Water supply system WVA Krems – Well field Schlickendorf

Tasks definition

The municipality Krems was supplied solely from the groundwater supply plant Landersdorf. Additionally the second well field was to be connected.

  • Dimensioning for the purpose of guaranteed supply of needed water amounts also in extreme cases
  • Construction of wells, pumping stations, UV-disinfection facility and transmission pipeline
  • Determination of well protection area
  • Special attention was to be paid to amount of groundwater intake and consequent project demands in terms of technical and water law point of view
Solution
  • Preliminary investigation by survey drillings and short pumping tests, construction of well 1 and probe network
  • Long-term pumping test in well 1 with monitoring of groundwater level by probes
  • Evaluation of measurement for elaboration of groundwater layers drawings and depression cone design
  • Hydro-geological evaluation of investigations and determination of protection area
  • Pumping station and UV-disinfection unit
  • Construction of well 2 and 3
  • Laying of transmission pipeline DN 500
