Management of Rain and Waste Water 2012

Statistical Base

The sewerage network maps of the BWB provided the primary base to ascertain the type of drainage as well as the various catchment areas of rainwater drainage. With the aid of the current digital drainage network maps as of 2012, the map “Management of Rainwater and Waste Water”, developed as part of the Environmental Atlas as early as 1992, was again updated; it had already been digitized in the late ‘90s.
