Scaling up low-water sanitation in South Africa
The technology is clearly out there for South Africa and the world to rethink
sanitation systems.
In South Africa, one of the most important questions that needs to be addressed
for a sustainable future is how to scale up low-water sanitation (where water is
scarce). The Council for Scientific and Industrial Research (CSIR) and the Water
Research Commission have established that social franchising partnerships for the
maintenance of infrastructure could alleviate and address many challenges in the
management of water services.
As the recent 2015 drought has shown, there is an urgent need for new and
disruptive technologies that can combine South Africa’s sanitation needs with social,
environmental and financial sustainability. The technologies are available and there
could not be a better time to make use of them.
