Bank filtration

As a bank filtrate domestic or potable water is called, which is obtained from wells in the immediate vicinity of rivers or lakes and therefore there is a significant proportion of water from these surface waters.

The bank filtrate is therefore largely determined by the nature of the surface water used in terms of its quality. It will thus be necessary in most cases to apply appropriate methods of water treatment prior to feeding into the supply networks. This concerns in particular the aspects of sanitation. Next precaution shall be taken for the detection and handling of exceptional contamination of surface waters. These include:

  • Ongoing quality monitoring of surface water (monitoring) and
  • Emergency Planning (replacement supply, disabling the removal of bank filtrate in order to avoid possible contamination of surface water into the groundwater body )
