Population growth and industrial expansion across Africa have led to increased wastewater generation, reducing water quality across the region. Existing treatment methods fall short of safeguarding public health, aquatic ecosystems, and water resources, which leads to inadequate sanitation and safe water access. These shortcomings pose severe risks, especially to vulnerable groups such as children, women, and disabled individuals in remote and rural areas with limited healthcare. Based on a review of recent literature and international health data, key interventions are identified to address these challenges. These include developing indigenous innovative technologies, establishing treatment infrastructure in rural locations, training personnel, enhancing operation and maintenance, and improving electrical power supply. Progress also depends on establishing local water quality benchmarks, boosting public involvement, and securing governmental and international technical and financial support to meet clean water goals.
Poor wastewater management compromises aquatic ecosystems and public health, especially in communities with limited healthcare infrastructure. Clarifying the operational and systemic deficits across African wastewater systems helps policy makers, funders, and environmental organisations direct resources effectively. Adopting targeted solutions is vital for protecting essential water reserves and advancing international sustainable development targets for clean water and sanitation.
The findings point to opportunities for technology developers and engineering enterprises to introduce indigenous treatment innovations and rural infrastructure adapted to local requirements. Opportunities also exist for commercial providers in technical training, operations, and facility maintenance. However, because the abstract outlines broad recommendations from a literature review rather than a specific tested device or process, direct commercial deployment pathways remain at a conceptual and strategic stage.

In Africa, the growing population and industrial growth have resulted in a notable increase in wastewater generation, affecting the quality of water in the region. Wastewater treatment plays a crucial role in safeguarding the environment, public health, aquatic organisms, and water resources, reducing environmental impact, and adhering to regulations. However, the current methods for treating wastewater in Africa fall short of these goals, resulting in substantially poor environmental and health outcomes and inadequate provision of safe water and essential sanitation. Poor wastewater management in several African countries has led to severe health risks for humans, animals, and aquatic ecosystems. This poses a particular threat to vulnerable groups like children, women, and the disabled residing in rural and remote areas with limited access to healthcare. Hence, this article aims to shine a spotlight on the difficulties in managing wastewater in Africa and to recommend several plausible strategies to tackle this issue. A literature search to find the most recent and relevant research papers from various databases, such as Scopus, Web of Science, PubMed, and Google Scholar, along with resources from the World Health Organization, was conducted. The selection criteria focused on including the most recent and relevant publications published in English to facilitate comprehension, analysis, and interpretation of the secondary data. Essentially, addressing the challenge of wastewater management in Africa requires developing indigenous innovative technologies, transitioning to a sustainable economy, establishing wastewater treatment infrastructures in rural and remote areas, enhancing operation and maintenance practices, training treatment facility workers, improving electricity supply, strengthening government participation and support, encouraging public involvement, setting local water quality benchmarks, and international financial and technical support. By tackling the problem of insufficient wastewater treatment in Africa, it is possible to achieve Sustainable Development Goal 6, which centers on ensuring clean water and sanitation for all.
