PRETORIA, Gauteng — The escalating South Africa water crisis has been laid bare by new revelations that only 14 of the country’s 848 municipal wastewater treatment plants discharging into waterways are fully functional. This stark assessment from the Department of Water and Sanitation follows a severe contamination event at the Bronkhorstspruit Water Treatment Works, which left over 400 residents ill after three weeks of unchlorinated water.
The recent crisis in Bronkhorstspruit was attributed by the city to a contractual deadlock with a single chlorine supplier, raising questions about the fragility of the national water ecosystem. Dr. Murendeni Ravele, a researcher at North West University, argues that such vulnerabilities stem from a lack of proper maintenance and poor fund management rather than isolated supplier disputes.
According to Dr. Ravele, sustainable water treatment requires scheduled maintenance and appropriate financial allocation, which must be tailored to the age and technology of the facilities. For instance, older infrastructure like the Rustenburg plant, established in 1920, requires significant systemic management changes, whereas newer facilities like Hammanskraal require funding directed toward staff skills development.
The systemic nature of the crisis is further highlighted by the latest Green Drop Report, which indicates that less than 2% of municipal wastewater treatment plants discharging into rivers are up to standard. Dr. Ravele notes that the contamination does not begin at the tap but is heavily influenced by human behavior, such as the improper disposal of diapers into raw water systems, combined with a general lack of public awareness regarding water infrastructure.
Beyond municipal failures, industrial pollution poses a severe threat. Dr. Ravele warns that thermal, agricultural, textile, and pharmaceutical industries are leeching unaccounted contaminants into the environment. Recent findings of endocrine disruptors in the water system highlight the danger of “contaminants of emerging concern.” Because current treatment methods are already failing to manage standard pollutants, the country lacks the advanced, costly technologies required to treat these emerging chemical threats.
While the Department of Water and Sanitation has laid over 100 criminal charges against municipalities for water pollution, Dr. Ravele emphasizes that fines alone are insufficient. She advocates for a collaborative approach involving policymakers, researchers, and the public to scale up lab-tested water treatment technologies.
A critical component of this solution is data transparency. Following communication failures regarding chlorine shortages in municipalities like Tshwane and recent contamination issues involving Johannesburg Water, Dr. Ravele stresses that municipalities must stop hiding data. Transparent sharing of contamination reports would allow neighboring municipalities to implement preventative measures before a localized issue becomes a regional crisis.
With local government elections just 10 days away, water security is expected to be a primary grievance for millions of voters. When asked about the readiness of the country’s systems, Dr. Ravele delivered a sobering verdict: South Africa is currently not ready to provide safe drinking water to its people. With existing treatment methods failing and the financial burden of adopting advanced technologies looming, the nation faces a monumental task in securing its water future.
