摘要
Structurally weak rural areas in Germany partially are confronted with enormous challenges. It is becoming increasingly difficult to provide these regions with an adequate infrastructure to secure equivalent living conditions. Alternative concepts such as New Sanitation Systems (NASS) can offer an essential contribution. The main idea of NASS is the driving of resources within urban water circular paths. Therefore a separated collection of waste water flows through a technical re-design of infrastructure systems becomes necessary. Winning and utilizing resources offers a new perspective of value adding for urban water management. The paper addresses the organizational problems regarding the background and deficits of conventional sewage systems. Especially in the context of important changes, such as demographic development and climate change, new framework requirements for planning need to be taken into account. Therefore it is investigated which constraints and challenges influence the implementation of new technical and organizational solutions for sanitation systems.
