South Africa's Top Court Orders Major Polluter to Protect Public Water and Land

Contaminated groundwater, polluted wetlands, and streams running near one of South Africa’s largest power stations: these are the conditions that prompted a landmark ruling on August 14, 2026, when the Supreme Court of Appeal found that Eskom and senior government officials had both failed in their duties to protect the public and the environment around the Kusile coal power station in Mpumalanga province.

The stakes for ordinary South Africans are considerable. Coal-fired stations generate about 74 percent of the nation’s electricity, and Kusile alone produces enough power to supply more than three million homes. Yet the same facility had been discharging pollution into groundwater, wetlands, and nearby rivers in violation of its own environmental authorisations and water-use licences. Those licences are legally binding requirements, not administrative suggestions. Water tests repeatedly showed pollution levels exceeding permitted limits, monitoring reports arrived late or incomplete, and promised remedial steps went unexecuted.

The case reached the courts after Topigs Norsvin, a pig-breeding company operating downstream of Kusile, found that polluted water from the station had entered local water sources and threatened its farming operations. The company joined Kusile’s environmental monitoring committee and raised its concerns there. When those concerns went unaddressed, Topigs Norsvin filed legal action in 2023. The High Court dismissed the application in June 2024. On appeal, the Supreme Court reversed that decision entirely.

What changed with this ruling is the clarity it brings to public accountability. The court found that senior officials at the Department of Water and Sanitation and the Department of Forestry, Fisheries and the Environment had acted unlawfully by choosing inaction when environmental rules were breached. Both the National Environmental Management Act and the National Water Act give regulators specific powers to respond to violations. The court rejected the argument that judicial oversight would encroach on government authority, ruling instead that courts can order regulators to exercise the enforcement powers they already hold, without dictating the precise form that enforcement must take.

The judgment also settles a question that matters well beyond Kusile: environmental approval does not exempt a developer from the conditions attached to that approval. Permission to build is not permission to pollute.

The court set a concrete accountability timeline. Eskom must submit a sworn remedial plan within 30 days and report on progress within 60 days. Senior officials responsible for water and environmental affairs must report within 75 days on what enforcement action should be taken against the company. Eskom retains the option to seek leave to appeal to the Constitutional Court, though such leave is not automatic.

Meanwhile, the practical value of the ruling depends entirely on what follows. A court order cannot clean contaminated water by itself. Whether pollution levels actually fall and water quality downstream of Kusile genuinely improves will depend on whether Eskom’s plan addresses root causes, whether the company executes it on schedule, and whether regulators act if violations continue. The officials now required to report on enforcement are the same officials the court found had already failed to act. That tension sits at the heart of what comes next.

For citizens living near coal infrastructure across South Africa, the ruling offers a precedent: that environmental protections remain enforceable after a project is built and operating, and that both the companies running those projects and the officials charged with oversight can be held to account when those protections are ignored. Whether this case becomes a turning point or a footnote will be determined not in court, but in the months of implementation ahead.
