Decentralized Water Supply and Disposal Systems

This research program was mainly designed to combine and to improve existing components (i.e. membrane technology). Apart from the reduction of the drinking water consumption key aspects are to decouple materials and water flows (i.e. separation toilets; waterless urinals) such that recovery of nutrients and energy will be possible and economically efficient.

The BMBF research program is mainly designed to combine and to improve existing components (i.e. membrane technology). Apart from the reduction of the drinking water consumption key aspects are to decouple materials and water flows (i.e. separation toilets; waterless urinals) such that recovery of nutrients and energy will be possible and economically efficient.

Subjects of investigation are: Anaerobic waste water treatment, membrane filtration, processes close to nature, reuse of gray water and rainwater, separation vacuum and compost toilets, winning of biogas and decentralized power stations, production of compost and fertilizers, economic, socio-cultural, and legal aspects.

Concerning the implementation and dissemination of the research results, an adequate contribution from German private companies as well as from the foreign partners is required.

Especially with the international BMBF research projects, we wish to contribute to a more conscious and sustainable use of water, a resource that cannot be replaced. Accordingly, these projects contribute to the ambitious aims of the Sustainability Summit of Johannesburg, which was to halve, by the year 2015, the proportion of people who are unable to reach or afford safe drinking water and do not have access to basic sanitation.
