Water sanitation programmes in Soweto, Johannesburg have been implemented to improve public health outcomes. However, community feedback surveys and their impact on programme evaluations are not well-documented. A comprehensive search strategy was employed using databases such as PubMed, Cochrane Library, and Google Scholar. Studies published between and were included based on predefined inclusion criteria. Community feedback surveys report mixed results regarding programme impact on health improvement. A notable theme suggests that regular survey reporting leads to better community engagement and support for programmes. Current literature highlights the importance of transparent and consistent communication through feedback surveys in sustaining water sanitation programmes' success. Future evaluations should incorporate more frequent and structured community feedback mechanisms to enhance programme sustainability and impact. Treatment effect was estimated with $\text{logit}(p_i)=\beta_0+\beta^\top X_i$, and uncertainty reported using confidence-interval based inference.
