"To the Berliner Wasserbetriebe, ecological aspects are as important as economic and social issues. This especially refers to the sustainable use of our water resources. Moreover, we are anxious to contribute to the environmental protection by taking a stand for more energy efficiency and an increasing amount of energy supply through renewable energy resources. Therefore, we are glad to join the network "NetzwerkE", launched by the Berliner Energieagentur. Using the networks platform as a place of knowledge transfer we, together with other partners of the NetzwerkE, elaborate on innovative solutions for energy-efficient utilization of sewage."
