This prefeasibility study will apply an integrated Water-Energy-Food (WEF) Nexus approach to examine appropriate nature-based technologies that can expand the scope of the current activities at the Franschhoek Water Hub to treat wastewater and recover reclaimed water and other resources from informal settlements in Western Cape. It will support to ensure the improvement in water, energy and food security in the Western Cape Province while protecting the environment and regenerating ecosystem services, hence helping to achieve the UN SDGs. As such the project’s Nexus approach will take WEF as the starting point, but explicitly includes other relevant sectors such as waste and ecosystem services as a basis for a just transition to a Circular Economy.
