Sustainable Wastewater Management in Nigeria: A Case Study of Port Harcourt

Abstract

Wastewater management is a critical challenge facing rapidly urbanizing cities in developing countries, with significant implications for public health, environmental sustainability, and socio-economic development. This study investigates the complex challenges and opportunities for sustainable wastewater management in Port Harcourt, Nigeria, through a quantitative survey of government officials, experts, and community residents. The research addresses four central questions related to current practices and challenges, the effectiveness of existing systems, key sustainability issues and concerns, and potential improvements to integrate sustainability principles. The study employs a correlational design and an online questionnaire to collect data from 80 participants, comprising 66 government officials, experts, and 14 community residents. The findings reveal significant associations between various aspects of wastewater management and sustainability, highlighting the multi-dimensional nature of the problems facing Port Harcourt's wastewater systems. The results suggest that improving the sufficiency of collection methods, adequacy of treatment, and enforcement of regulations could enhance the effectiveness of wastewater management and mitigate public health risks. The study also underscores the importance of addressing infrastructure gaps, social and cultural barriers, and policy gaps to enable transitions towards more sustainable wastewater practices. The discussion of the findings links the results to the existing literature and theoretical frameworks on sustainable wastewater management in developing urban contexts. The study contributes to the body of knowledge by providing empirical evidence, applying a sustainability lens, employing quantitative methods, and emphasizing stakeholder engagement in the specific context of Port Harcourt. The study highlighted the urgent need for a comprehensive, sustainability-oriented approach that addresses wastewater systems' interrelated technical, environmental, social, economic, and governance dimensions.
