Nature-Based Solutions for Water in the ...

A brief description of the case study on green infrastructure to improve wastewater management in an informal settlement (slum) named Langrug near Franschhoek, in South Africa.. Wastewater and solid waste accumulate in its streets, due to lack of service provision and sewerage. Surface hardening contributes to localised flooding. The Genius of SPACE (Systems for People’s Access to a Clean Environment) was a pilot project implemented in Langrug which applied NBS with the following aims in mind: 1) treat and manage wastewater and greywater entering the stormwater system; 2) manage solid waste; 3) empower local community members; 4) improve living conditions and promote social upliftment. The NBS involved installation of 27 greywater disposal points, inserting underground wastewater pipes, laying permeable paving, road grading, pavement construction and establishing 15 tree gardens for water infiltration. This case study aimed to assess the project in terms of the benefits and co-benefits produced, along the 3 sustainability dimensions. It also aimed to understand the major barriers and challenges, besides the contexts that would be most favorable for the project.
