Within this project component, the investment costs of the system and the running costs for its operation (personnel, maintenance, water & wastewater, electricity) as well as the reinvestment costs and the amortisation point will be determined.  Additionally, comparative calculations will be done with other projects/locations having source separation sanitation systems as well as with conventional systems.

Moreover, the two ways of urine reuse that are being investigated in the project (direct application of urine vs MAP precipitation and utilisation of the product)  will be analysed by a direct comparison.

The principal lead of this focus point is GIZ.  GIZ will work together with the University of Bonn in assessing the feasibility of urine reuse.
