Water supply system WVA Schrems - horizontal filter well

Tasks definition

The water supply system in Schrems is supplied by water from wells and springs. A total capacity from all sources is 20 l/s. During the dry periods a total capacity drops to 10 l/s.

  • An increase of the supply efficiency during the dry periods to be achieved by connection of additional water source.
  • Determination of the exact location of well, based on the geological and hydro-geological investigations.
  • Investigation of interaction between designed well and existing wells and ditch.
  • Determination of necessary protection area for a well.
  • Preliminary investigation by survey drillings and short pumping tests, Installation of probes network.
  • Pumping long-term test with monitoring of water level in probes.
  • Evaluation of measurement for elaboration of groundwater layers drawings, Determination of groundwater stream relations.
  • Hydro-geological evaluation of investigations and determination of protection area.
  • Construction of well as „horizontal filter well“.
  • Pumping tests after the construction of the well in order to determine the exact capacity of the well.
