Sewage Farms 1992
The sewage farm districts in the map are based on maps (scale: 1:10,000 or 1:25,000) produced in the 60’s in commission of the Berlin Water Supply and Waste Water Treatment (WAB). These borders were drawn on the basis of older basic map data from the WAB Berlin archives, the Berlin State Library and the Berlin Waterworks. Sewage farms discontinued before 1960 could thus be defined.
Further information on length of operations, type and intensity of use, and special-use areas are derived from written information or information from employees of WAB Berlin, the Berlin Waterworks, WAB Potsdam and Königs-Wusterhausen.
