Pollution Persists: Milnerton Lagoon's Lingering Sewage Crisis Despite Cleanup Orders

The picturesque setting of Milnerton Lagoon in Cape Town is marred by a persistent sewage stench, leaving residents demanding action and accountability. Four years have elapsed since the Western Cape environmental inspectorate mandated the City of Cape Town to undertake comprehensive cleanup efforts. Despite these directives, the situation appears to have deteriorated, posing significant environmental and public health risks.

The pollution primarily stems from the malfunctioning Potsdam Wastewater Treatment Works (WWTW), which discharges over 40 million liters of sewage daily into the Diep River, feeding into Milnerton Lagoon. Despite claims from city officials that the issues do not originate from the Potsdam facility, data from the Department of Water and Sanitation contradict these assertions, highlighting ongoing compliance failures in effluent quality tests.

Residents like Caroline Marx, an environmental activist, express their frustration as the foul odors intensify, indicating severe pollution levels that make outdoor activities near the lagoon unbearable. The dire situation underscores the urgent need for the city to enhance its management and treatment processes, especially since the lagoon serves as a crucial nursery for various fish species.

Indeed, the City has initiated a R5.2 billion upgrade of the Potsdam WWTW, intended to substantially improve the situation by its expected completion in 2027. Short-term measures have also been expedited, aiming for noticeable improvements by mid-2025. However, the community remains skeptical, having witnessed only minimal progress in the water quality, which continues to violate national health standards.

Moreover, recent water quality tests reveal exceedingly high levels of E. coli downstream from the treatment plant, emphasizing the severe health risks and the plant’s role in the lagoon’s pollution. The City has made its inland water quality test results publicly available, attempting transparency, but the ongoing pollution raises questions about the effectiveness of current interventions and the pace of the promised upgrades.

Legal enforcement continues as the Western Cape Department of Environmental Affairs and Development Planning rigorously monitors the situation, ensuring that the city adheres to the cleanup directive. However, as the lagoon’s condition worsens, local entities like the Milnerton Canoe Club have ceased activities, reflecting the broader community's diminishing hope for a swift resolution.

In conclusion, the Milnerton Lagoon crisis symbolizes a critical environmental management challenge, requiring immediate and effective action to rectify the ongoing sewage issues. As the local government, environmental agencies, and the community grapple with these challenges, the resolution of this pollution crisis will undoubtedly serve as a benchmark for environmental accountability and governance in South Africa.
