Winter is nearly over, and most Johannesburg homeowners are looking forward to it.
They probably shouldn’t relax just yet. August has been one of the more disruptive months of the year for the city’s water supply, and the timing could not be worse. Just as demand starts climbing into spring, the network delivering that water is showing exactly how strained it has become.
The Fire That Cut Water to Half the City
On 24 August, an underground fire in tunnels carrying high-voltage cables forced the shutdown of the Fordsburg electricity substation. Because so much of Johannesburg’s water system depends on electrically powered pump stations, the knock-on effect reached far beyond Fordsburg itself, triggering water supply problems across large parts of the city alongside the traffic chaos.
It is the same pattern we saw in July, when a substation failure at Eikenhof turned a planned maintenance shutdown into days without water for thousands of homes. Power and water in this city are now tied together in a way that means an electrical fault on one side of Johannesburg can leave taps dry on the other.
The Randpark Ridge Burst That Wouldn’t Cooperate
A few days earlier, on 19 August, a major pipe burst at the corner of Dale Lace Avenue and Knoppiesdoring Street left thousands of households across Randburg without water. Johannesburg Water’s teams reached the site and excavated the burst, but ran into technical difficulties completing the repair, leaving residents waiting longer than expected.
This is not an isolated bad week. Johannesburg is currently losing an estimated 655 million litres of water a day to burst pipes – more than a third of the water entering the system. Large sections of the network are up to 80 years old, and the city only managed to replace 17km of pipe in the last financial year. Underneath all of it sits a funding problem: National Treasury withheld funding from the metro in July over financial management failures, and the city’s own R97.1 billion budget has been described as unfunded. None of that gets resolved quickly, which means more bursts like Randpark Ridge should be expected, not treated as surprises.
Why Spring Changes the Rules for Your Plumbing
August in Johannesburg is dry, windy and warming up fast – daytime temperatures are already climbing while nights stay cool, with barely any rain to speak of. That combination matters more for your plumbing than most homeowners realise.
As the ground dries out after winter, clay-heavy Johannesburg soil contracts. Pipes and joints that were sitting comfortably in damp ground during the wetter months can be left with less support than they had a few weeks ago, which is part of why burst reports tend to climb through August and September. Wind is a factor too, it loosens debris into gutters and downpipes, and can work at already-weakened external fittings without you noticing until a leak shows up.
Then there’s demand. As soon as temperatures rise, irrigation, pool filling and general water use all climb sharply, right as Gauteng’s utilities are warning residents to cut back rather than ramp up. A system already losing a third of its supply to leaks has very little slack left to absorb a spring demand surge.
The Best Time to Deal With Your Solar Geyser Is Before Summer, Not During It
We still get asked constantly whether a solar geyser rebate exists. It doesn’t – Eskom’s old programme ended years ago, nothing municipal or national has replaced it for homeowners, and SARS Section 12B (the tax incentive people keep confusing it with) only ever applied to business-owned solar PV, never to residential geysers.
What has not changed is the maths. A 150l solar geyser installed today typically costs in the region of R22,500 to R42,500 and saves roughly R765 to R900 a month against a standard electric geyser at current tariffs – a payback period of under three years, followed by well over a decade of near-free hot water. Spring is the practical window to act on that: installers are less booked up than they will be once summer demand peaks, and a system going in now gets the benefit of lengthening days and a higher sun angle almost immediately.

What We’d Check Going Into Spring
A few practical steps matter more right now than at almost any other point in the year. Have your geyser’s insulation, anode rod and expansion valve checked before the heavier spring and summer usage begins – a unit that limped through winter is not necessarily ready for what’s coming. If you’re on a backup tank or borehole system, get it serviced and confirmed leak-free before demand spikes make it your primary supply on more days than you’d like. And if you’ve noticed any new dampness, cracking, or a shifting path in your garden since winter, have it looked at, ground movement after the dry season is a common, and often missed, cause of underground pipe failure.
Not sure whether your geyser, tank or pump setup made it through winter in good shape? We can check it properly before spring puts it to the test.
The Bottom Line
August gave Johannesburg two clear warnings: a substation fire that cut water across the city, and a burst pipe that engineers struggled to repair quickly. They’re what an ageing, underfunded network does more often as it comes under more pressure, and spring is about to bring more pressure, not less.
The homes that get through the next few months comfortably are the ones that dealt with their plumbing before the demand surge arrived, not after. If winter left you wondering about the state of your geyser, pipes or backup water supply, now is the moment to find out.
