GREENTECH! - Sustainable Water Management

Global water consumption is growing faster than the population. That’s why a sustainable use of the limited water resources on earth is critically important. Saxony’s companies are developing new technologies particularly for the ecological purification of wastewater – both at a private and an industrial scale.

The competences of the Stadtentwässerung Dresden GmbH in the field of wastewater treatment and disposal are also in great demand around the globe. For example, wastewater projects in Vietnam and the Ukraine have already benefitted from the extensive knowledge and expertise provided by the Dresden- based firm. In both countries, pilot projects were realized within the scope of the International Water Research Alliance Saxony (IWAS), a network project that includes the Helmholtz Center for Environmental Research (UFZ), Dresden University of Technology, and other partners, with the objective of improving the water quality and/or developing a sustainable wastewater management system. The company seeks to install an energy self-sufficient sewage system at its corporate site Dresden.


The BUSSE Innovative Systeme GmbH from Leipzig specializes in the development, construction, and distribution of decentralized wastewater treatment and water recovery systems. Its most popular product is the BUSSE-MF sewage treatment system – a fully biological, small-sized sewage system which treats and purifies domestic wastewater up to the quality of industrial water. In a current research project, the BUSSE IS GmbH is cooperating with the Fraunhofer IKTS Dresden in order to investigate how such organic trace substances as hormone and pharmaceutical residues can also be removed almost completely from municipal wastewater. Towards this end, the BUSSE procedure is to be expanded by a hybrid membrane system.
