Hi Miriam, I work with the Future Water Institute and do research on resource recovery from wastes, which has brought me closer to sanitation.

On a personal note I have a UD compost toilet in my house to test it as a viable alternative and to learn about bioprocessing of the solid product.
There is also the Water Hub that aims to test innovations in real world context: https://www.thewaterhub.org.za/
Isidima has been mentioned, they do good work on multiple scales/aspects and is one of the partners at the Hub: https://www.isidima.net/
Other innovations may be available through the WADER programme: http://wader.org.za/
A recent conference brought many of the people working in this field together: http://periurbanconference2017.org.za/programme/
Then, we are working with Sanergy in Kenya that seems to have a very good approach to the whole system: http://saner.gy/
Chris Buckley's group is also doing great work: http://prg.ukzn.ac.za/
Lastly, I agree with the comments from Barry Jackson.
I am also based in Cape Town and would be keen for an interview, and look forward to following your work :)
