Open to Letter Panyaza Lesufi: An Early Warning on the Imminent Collapse of Gauteng’s Wastewater Systems

Dear Panyaza,

I am writing to you today not to react to a tragedy that has already passed, but to issue a critical early warning about a looming catastrophe that threatens the economic and environmental future of our province. Gauteng is the industrial and economic heart of South Africa, but beneath our feet, the arteries that sustain us are failing.

We currently treat nearly 1.9 million kilolitres of wastewater every single day, which is the highest volume in the country. However, our province is currently operating on the edge of a precipice. Eight of our wastewater systems have already exceeded their design capacity. Furthermore, 14 systems have surged past their available capacity.

This is not merely a technical bottleneck; it is a hard ceiling on our socio-economic growth. We cannot build new houses, attract new factories, or expand our cities when the pipes intended to carry waste are already overflowing.

Before this situation devolves into an unsalvageable crisis, I must urgently draw your attention to the R2.14 billion required just to restore our wastewater infrastructure to a functional state.

Over half of that cost is driven by the urgent need for mechanical refurbishment of pumps, motors, and processors. These critical components have been run into the ground through poor maintenance and the relentless shocks of load-shedding and vandalism.

We are already seeing early indicators of cascading failure in municipalities like Johannesburg and Mogale City. When power goes out or a pump is stolen, the system backups, often spilling raw sewage into our streets and rivers.

The most damning evidence of this impending failure is that 57% of Gauteng’s wastewater systems are now in the “critical bracket” for effluent compliance. This means that more than half of the water being discharged back into our rivers is substandard, polluted, and dangerous.

We must act proactively to prevent a repeat of the human cost seen in the Emfuleni Local Municipality. Sebokeng system’s failure led to long-term, high-volume spills that were so severe they required intervention from the South African Human Rights Commission. This is a violation of the basic right to a healthy environment.

While Gauteng still possesses a relatively strong base of technical supervisors and process controllers, their expertise is being wasted by severe engineering shortfalls in areas like Merafong and Rand West. We cannot afford to sit idly by while our rivers are poisoned.

To avert this silent collapse, I urge your office to proactively implement the following immediate measures:

• Immediate Infrastructure Audit: Conduct a transparent, province-wide assessment to close data gaps.
• Emergency Funding Realignment: Prioritise the R2.14 billion required for mechanical refurbishment before the systems become unsalvageable.
• Ring-fenced Security: Institute dedicated protection for high-risk pump stations to prevent the vandalism that triggers major spillages.
• Accountability for Polluters: Hold municipal managers personally liable for the discharge of substandard effluent into our water sources.

We have the skills, and we have the technology. What we require now is a government that treats our water security with the proactive urgency it deserves, rather than waiting for the system to entirely break down. Let us ensure that Gauteng remains a province where life and the environment can thrive.
