South Africa’s major metropolitan areas are grappling with a systemic collapse of wastewater treatment infrastructure, resulting in the regular discharge of raw sewage into urban rivers, coastal waters, and community drainage systems. The Department of Water and Sanitation has documented this decline through its Green Drop and Blue Drop reporting cycles, noting that persistent underinvestment and the loss of skilled technical staff have brought many municipal plants to a standstill.
The crisis is particularly visible across metros including eThekwini, the City of Johannesburg, and the City of Ekurhuleni, where aging infrastructure is unable to process current waste loads. According to the South African Human Rights Commission (SAHRC), which released detailed findings on these failures on 15 March 2024, the situation extends beyond mere operational inefficiency. The commission argues that the ongoing pollution of public water sources represents a direct infringement on the rights of citizens to live in a healthy and dignified environment.
The failure to maintain wastewater treatment works is not just a service delivery issue; it is a fundamental violation of constitutional rights to dignity and a healthy environment.
The SAHRC report follows earlier warnings in the 2022-2023 Green Drop progress reports, which showed a significant downturn in the performance of municipal facilities. Researchers noting the environmental impact indicate that the discharge of untreated effluent into the environment introduces severe health risks, particularly for informal settlements and residential areas situated downstream from treatment outlets. The potential for waterborne diseases and the degradation of local biodiversity remain major concerns as municipalities struggle to secure both the capital budgets and the specialised personnel required to restore functionality to these plants.
While specific figures regarding the total volume of untreated discharge remain unverified—as they are currently based on local observations and regional environmental reports that require a nationwide audit to confirm—the impact on local economies and community health is becoming increasingly difficult to ignore. The failure of these systems forces communities to contend with regular flooding of sewage into streets and the contamination of recreational coastal waters, often limiting economic activities like fishing and tourism in affected regions.
We are currently checking with the Department of Water and Sanitation for the latest status on planned infrastructure interventions in the Western Cape. Further reporting will follow as the SAHRC evaluates municipal responses to their most recent findings.
