User perceptions and acceptance of treated greywater reuse in low-income communities: a narrative review

Abstract This research output established that a significant proportion of the global population lives in low-income communities mostly in the Global South. These communities face severe water scarcity and persistent sanitation challenges. It emerged that greywater reuse has the potential to improve the access to sufficient clean water in low-income communities. The study sought to ascertain user perceptions and acceptance of treated greywater reuse in low-income communities. To anchor this research, a comprehensive consultation of literature was done, and key sources of data were drawn from various secondary sources of data such as bibliographic databases. This was followed by the snowballing of obtained papers. The research employed a narrative review approach in methodology. The findings of this study indicate that people living in low-income communities have a positive perception regarding reusing treated greywater. Furthermore, it was established that the majority of persons living in low-income communities accept reuse for non-potable purposes including vegetable irrigation, laundry, toilet flushing, and car washing.
