    Adoption of constructed wetlands in informal settlement
    (University of the Witwatersrand, Johannesburg, 2023-08) Jetha, Hemal Girish; Thatcher, Andrew
    The study aimed to assess the effectiveness of constructed wetlands as a solution to greywater treatment in the context of water use in Setswetla, Alexandra, an informal settlement in Johannesburg that is characterized by makeshift housing, poor sanitation, and a lack of proper greywater treatment facilities. The lack of such facilities has resulted in the disposal of contaminated greywater across the settlement, which poses serious health risks to its people. The installation of constructed wetlands was considered a feasible solution, given that they can be built without displacing the population. However, the successful implementation of this solution would require a change in the behaviour of the population regarding greywater disposal. Therefore, this study aimed to evaluate the adoption of constructed wetlands which were installed in one portion of Setswetla, Silvertown to gain a better understanding of whether installing constructed wetlands helps with greywater disposal. The study also sought to determine if there was any difference in water use behaviour before and after the installation of the constructed wetlands. The research revealed that there was not much behaviour change pre- and post-installation of the constructed wetlands. Some of the significant differences found was that more people reported that they do collect the same amount of water during both summer and winter. More participants indicated that they do not collect the same amount of water during the week and weekend. Less participants reported that they could collect water during the day and night.
