Water Catchment and Levels in the Soil

A catchment area or a part of a catchment area of a water gathering installation that is subject to the protection of water utility limitation.”

According to the DVGW working paper W 101 [DVGWW101], the water catchment area is usually divided into 3 protective zones:

  • Zone I : Collection region (Abschnitt 6.3)
  • Zone II : Inner protected zone (Abschnitt 6.4.1)
  • Zone III : Extended protected zone (Abschnitt 6.5.1)

The water catchment area is usually divided into 3 protective zones:

  • Zone I : Collection region (Abschnitt 6.3)
  • Zone II : Inner protected zone (Abschnitt 6.4.1)
  • Zone III : Extended protected zone (Abschnitt 6.5.1)

The limitation for particular types of utility and the protective measures for the water increase in the sequence zone III – zone II – zone I. Insofar as different requirements are applied within the protective zone III, they can be subdivided, for instance, into the zones III B, III A whereby A designates the inner and B the outer area.

Water Catchment and Levels in the Soil

The size of Zone I should in general extend 10 m from springs in all directions, for wells 20 m in the direction of the incoming groundwater and at least 30 m from karst groundwater inlets.

The zone II extends from zone I up to a line from which the groundwater requires approx. 50 days to reach the drinking water gathering installation. A zone II can be dispensed with if only deeper, sealed groundwater levels or such are used that from the 50 day line up to the collection point are sealed from the elements by impermeable layers.

The zone III extends from the limit of the catchment area up to the outer limit of zone II. When the catchment area extends more than 2 km, then a subdivision into a zone III A up to approx. 2 km from the collection region and a zone III B up to the border of the catchment area can be practicable.
