Modelling the next generation of sanitation systems To develop an easy-to-apply simulation tool set up to enable local city managers to assess the implications of adopting alternative sanitation strategies at scale.
The project develops a simulator for sanitation systems. The novelty of this project lies in the adaptation of an existing resource-flux simulation methodology used on networked systems to calculate nutrient and energy fluxes specifically for on-site sanitation systems. The simulation methodology has been already applied successfully by ifak in several networked sanitation contexts in developing countries. However, the concept is currently being extended to cater for non-networked sanitation systems. The model outputs are the main fluxes of energy and nutrients and, thus, their available amount for recovery, volume/quality of treated waste for reuse; and monetary value of the waste reuse. Demonstration of systems which have increasing commercial viability due to waste reuse/nutrients recovery can be used to explore business opportunities for sanitation. The flexibility of the simulator also allows to include in the future modules for sanitation technologies developed in the future. Once further developed, the model will have the potential to aid city-managers to evaluate alternative sanitation technologies and to select the most sustainable and cost-effective solution. Significant cost-savings and improved utilization of resource streams, thus increasing revenue, are expected by application of this simulator.
Mission
The main aim of Phase-I is to develop a simulation tool to model flux of residual wastes from streams in the sanitation service delivery chain, focusing on nutrient and energy fluxes.Approach
Research or implementation partners: UCL is working in collaboration with ifak which is a non-profit institute for applied research at Otto-von-Guericke University in Magdeburg/Germany that develops simulation models for water and wastewater applications.Answer questions about the project
