Concrete block blamed for decade-long sewage crisis at Johannesburg school

A concrete block — likely construction debris — has been identified as the root cause of a terrifying sewage overflow at Laerskool Esperanza Primary School in Newlands, Johannesburg, according to Johannesburg Water spokesperson Nombuso Shabalala on November 16, 2025. But this isn’t a new problem. It’s the latest chapter in a sewage nightmare that residents say has been festering since 2009. Children play beside pools of raw sewage. The stench is so thick, teachers say they can’t open windows. And the water? Contaminated. E. coli and coliform levels have been off the charts since May 2025. This isn’t just a broken pipe. It’s a broken promise.

A Decade of Silence, Then a Blockage

Dawid van der Merwe, a former community liaison officer for Ward 86, spent years sending emails to Johannesburg Water — from 2009 through 2023 — begging for action. "The sewage leaks are not getting fixed," he wrote in one of many overlooked messages. "They’re popping up all over, especially near Esperanza. Nothing has changed. It’s only gotten worse." His emails weren’t anomalies. Residents reported overflowing manholes, sewage seeping into driveways, and children coming home with rashes. But the city’s response? Silence. Or, worse, promises that evaporated. Then, in May 2025, it got unbearable. Large pools of raw sewage formed beside the school’s playing fields. Toilet paper. Used sanitary products. The kind of debris you’d expect in a landfill, not a children’s playground. Parents stopped sending kids to school. Teachers took photos. Local conservationists, including Dr. Teresa Dirsuweit from UNISA’s Geography Department, traced the flow back to the decommissioned Waterval dump site, where sewage runs downhill like a dirty river — straight onto Stonewall Road and into the school grounds.

"A Health Disaster We Cannot Allow to Unfold"

By October 20, 2025, Chantelle Fourie-Shawe, the Ward 86 councillor, had had enough. She called for an online public meeting, inviting Johannesburg Water and environmental health experts. "This," she said, "is a health disaster we cannot allow to unfold." The evidence was undeniable. A WaterCAN.org.za report on November 4, 2025, confirmed over 37 formal complaints lodged since May. Johannesburg Water admitted they’d tried to clear the blockage themselves — but failed. The pipe was clogged with something too dense, too large. Then, on November 16, they revealed the culprit: a single, massive concrete block. Probably dumped during a nearby construction project years ago. It’s not a natural obstruction. It’s human negligence. And it’s been there long enough to become part of the system.

Why Did It Take So Long to Fix?

Here’s the twist: Johannesburg Water says they’ve been trying. But contractors won’t bid. Why? Because of unpaid bills. "Many service providers did not want to bid," Shabalala admitted. "The paperwork is currently being finalised with a new contractor." So the city couldn’t afford to fix a problem it had ignored for 16 years. A temporary trench was dug to divert sewage away from the schoolyard — a band-aid on a hemorrhage. Work could begin within days. But the real fix? A full sewer upgrade. That’s stuck in the city’s budgetary black hole. "The project depends on capital expenditure funding from the City of Johannesburg," Shabalala said. Meanwhile, the crisis is spreading. In Albertsville, residents report similar blockages. The Westdene Spruit, which flows through the Johannesburg Botanical Gardens, is choked with effluent. The Pampoen Spruit in Randburg? Grey, stinking, littered with toilet paper. And in Newlands East, a broken pipeline has been spilling into a stream since May 1, 2025 — a fact confirmed by IOL.co.za in August.

What’s the Real Cost?

The Bill of Rights guarantees every South African "an environment that is not harmful to their health or wellbeing." Yet here, children are exposed to fecal matter daily. Schools are being turned into biohazard zones. The long-term health impact? Unknown. But we know E. coli can cause kidney failure. Coliforms signal fecal contamination. This isn’t just a sewage issue. It’s a violation of basic human rights.

What’s Next?

The temporary trench is working — for now. But it’s not a solution. It’s a delay tactic. The new contractor is expected to begin removing the concrete block by November 20, 2025. But without funding for a full system overhaul, this will happen again. And again. And again.

Residents are now organizing. A community watchdog group has formed. They’re demanding independent water testing. They want CCTV installed in manholes. And they’re asking: if a concrete block can shut down a school for 16 years, what else is buried — literally — in this city’s neglected infrastructure?
