Semi-decentralized water and wastewater management
For more than a hundred years now, industrialized countries have been used to flushing feces together with valuable drinking water over long distances from urban areas to central wastewater treatment plants. This scheme has two costly drawbacks. It is expensive to build and maintain large sewer networks, and drinking water is a scarce resource, much too valuable to use for transporting waste.
In the DEUS 21 project (Decentralized Urban Water Infrastructure Systems), the Fraunhofer IGB was looking for more sensible alternatives to established water management systems – in order to save both resources and costs.
