June 2011 – September 2012
Phase I of the Reinvent the Toilet Challenge resulted in the development of a prototype pedestal for the segregation of excreta streams and processing of the individual wastes. Theoretical models were developed for the handling and treatment of urine, faecal matter and washwater. In order to develop the prototype and the models, an extensive sampling and analyses programme was undertaken to generate data on faecal matter. However at the end of this Phase, the final design could not be manufactured.
The main outcomes from Phase I highlighted the strengths of the UKZN team (through the PRG) and the importance of collaboration with EWS. This includes:
- Access to various on-site sanitation systems to obtain different excreta streams
- Sampling of these on-site systems
- Laboratory analysis to determine mechanical, chemical and biological properties of the various excreta streams
- Undertaking detailed investigations into the processing of segregated streams
Phase II of the project, therefore aims to build on the lessons learnt, knowledge, strengths and experience gained by the team during Phase I implementation
