Do we need New Alternative Sanitation Systems in Germany?
New alternative sanitation systems (NASS) are based on the separate collection, conveyance, treatment and reuse of source separated flows. The aim of implementing NASS is the reuse of water and the utilisation of useful substances extracted from wastewater (especially nutrients and organic matter).
The high adaptability and the potential for cost efficiency of NASS lead to long-term benefits. In order for decision makers to consider NASS, incentive mechanisms should be created for the transition period.
Incentives for the introduction of NASS are also sensible when considering the potential of NASS for the international market (for example, 2.6 billion people worldwide live without adequate sanitation, often under conditions of water, energy and fertiliser scarcity).
The propagation and implementation of NASS in Germany can be beneficial for entering new emerging markets abroad. This is particularly relevant in relationship to those countries that see Germany as a model for technical and sustainable development.
