South African municipalities have been plagued by poor service delivery, with many communities experiencing inadequate access to basic services such as clean water, sanitation, electricity, and waste removal. Despite the country’s progressive constitutional and legislative frameworks, the root causes of poor service delivery are complex and multifaceted. This study aims to explore the underlying reasons for service delivery challenges in South African municipalities, specifically focusing on the interplay between poor governance and structural and systematic factors. In other words, the study aims to identify and unpack the complex interplay between governance factors (such as corruption, political interference, and lack of accountability); structural factors (such as resource constraints, inadequate infrastructure, and capacity challenges); and systematic factors (such as historical legacies of apartheid, urban-rural divides, and socio-economic inequalities). The study employs a qualitative research approach, using document analysis to gather data. The data were analysed using thematic content analysis to identify the key themes and patterns that emerged from the data. The study draws on the New Public Management and Public Choice Theories to gain insights into the factors affecting service delivery. The findings highlight poor governance, urbanisation, corruption, political-administrative interference, political instability, and internal conflicts as major contributors to service delivery challenges in South African municipalities. Lastly, the study puts forth several recommendations to address these issues, including strengthening good governance and leadership, enhancing citizen participation, improving financial management, enhancing human resource capacity, fostering intergovernmental collaboration, reducing political-administrative interference, combating corruption, and addressing the impact of rapid urbanisation to promote sustainable service delivery.
