- In areas with a seperate sewer system the rainwater will be discharged into the waters.
From there for every block or partial block with a rain sewer system the water was defined,
into which the rain channel discharges, the so-called first absorb water. Totally there are about 180 of such waters or watersegments in Berlin.
For the map at hand these first absorb waters were combined to first absorb waters or
groups to get a clear description. Portrayed are the catchment areas of the accordant waters.
- It is assumed that green and open spaces, which have in all probability no sewer system, are not pictured and so they are not a part of the catchment area.
- The blocks and partial blocks of the map are always assigned to one of the first absorb
waters as a whole, even if in individual cases possibly several properties or a part of the block drains at the peripherie of two catchments into another water than others.
- Areas, in which the rain water will be leaded in local infiltration plants
(troughs- rigolsystems etc.) and which have only an overflow in a sewer system or a water for events of intense rain, are anyway assigned to those waters (e.g. Karow-Nord).
