Abstract

In the German Democratic Republic, the annually available mean recovered water resource per inhabitant is significantly less than in other European states. Approximately half of this quantity is actually available for utilization. Thus, the natural yield of water is very limited and an extensive expansion of water supply is impossible. About 75% is taken from surface waters and 25% from ground water. During dry months the multiple use of water increases to a factor of 3 to 4 in areas where industry and population agglomerate. The growing demand for water by population, agriculture and industry can be met only by an intensification of the utilization of water resources. But we cannot hope to manage water resources in a rational way unless we understand the relationships between the amount of water used by man, the input from man into ground and surface water and the resulting ecosystem response, especially the resulting water quality of rivers, lakes, reservoirs and aquifers.
