OUR CITY NEWS: Joburg power, water outages put medically vulnerable residents at risk

When the electricity goes off at John Gahle’s Johannesburg home, he does not simply wait for the lights to come back on. He starts calculating how long his oxygen will last.Gahle relies on an electrically powered oxygen concentrator and keeps cylinders as backup. He has spent more than R20,000 on backup arrangements. A 10-litre cylinder lasts about four hours. “That’s when I start to get panics... because I don’t know,” he said of outages whose duration is uncertain.For medically vulnerable residents, that uncertainty turns a municipal service failure into something more immediate. Electricity may be needed for oxygen concentrators, nebulisers, Continuous Positive Airway Pressure machines or refrigeration. Water is necessary for wound care, continence care and basic hygiene.John Gahle at his home in Katlehong, east of Johannesburg.

Caregivers may have to find water elsewhere, wait for tankers and transport containers home while still dealing with bedding and personal hygiene.Majoni pointed out that in some households people depended on refrigerated medication, prepared food or powered medical support. When electricity fails, “The food will definitely go off.” He said the practical and financial burden could shift to families and caregivers, who may have to arrange transport, find water or rely on community assistance when ordinary support systems failed.A registered nurse, who asked to be identified by professional role only, said prolonged outages could create serious risks for people who depended on electrically powered medical equipment.“Prolonged electricity outages can significantly affect patients who are dependent on home Continuous Positive Airway Pressure ventilation,” she wrote. “These machines do have batteries, but can only run for a certain period before needing to be charged.” She also identified patients who require home suctioning and nebulisation.A street vendor sits beneath overhead electricity cables during lunchtime in an industrial area outside Katlehong, in the East Rand. Despite efforts to improve service delivery, residents in Katlehong continue to experience electricity cutoffs.

Mark Rundle, the national president of the South African Association of Homes for the Aged, described similar problems in frail-care settings.Rundle described bedbound or chairbound residents who depended on staff for continence care and personal hygiene. “If you don’t have water for a couple of hours and days, it’s a serious situation,” he said.Care-home residents who rely on oxygen machines are also at risk during power outages.Rundle said that those with chronic respiratory conditions who depended on electrically powered oxygen equipment needed to be given bottled oxygen or may have to be transferred to hospital if the electricity remained off for too long.Better-resourced facilities may have water tanks, generators and solar systems, while poorer homes may have none. At the lower end of the sector, Rundle said, “you have no solar power, you have no diesel generators, you have no big tanks with pumps to keep water flowing”.The same outage could therefore have very different consequences depending on how much money the facility had.Drastic improvisationIn communities where care organisations already operate with limited resources, service delivery failures mean drastic improvisation.In Tshepisong, volunteers at the Power of Women and Children and Ithemba Labantwana Children’s Home must find firewood or paraffin to cook outside when there is no electricity. Children do homework by candlelight.Water shortages also affect the vulnerable. For those with disabilities, carrying containers or walking long distances to collect water is not possible. Volunteers must assist.Irene Molefe, founder and house mother at Power of Women and Children, and their liaison officer, Tom Fikiri, at the organisation’s premises in Tshepisong on Tuesday, 13 October 2026.

We can’t survive without water,” she said.Money gives people more options. A generator gives a household more time if there is fuel. Solar and batteries can keep essential appliances running. Water tanks can help during a temporary water interruption. Private transport can move someone to another place. Backup oxygen can keep someone going when the power is off. But all these things cost money.Those who can afford it are increasingly buying their own systems because they no longer trust municipal power to be reliable.Prince Jonah Jordan, owner of Lesiah Electrical Services, said his company saw a 35% to 45% increase in backup power and solar enquiries from 2024 to 2025.“Customers are also asking for larger hybrid systems with solar instead of small backup-only systems,” he said.According to Jordan, typical installation prices in Johannesburg and Pretoria could range from about R28,000 to R45,000 for smaller backup systems, R50,000 to R80,000 for mid-range systems and about R95,000 to R160,000 for fuller hybrid solar systems.Irene Molefe at Power of Women and Children.

One household may switch automatically to batteries. Another may be trying to decide whether there is enough power left to keep a medical device working. One facility may have a generator and water tanks. Another may be sending volunteers to collect water or buy paraffin.That is where the service-delivery problem becomes a healthcare issue, and it needs to be addressed.Responding to questions on this matter, Isaac Mangena, City Power’s General Manager for Public Relations and Communication, said medically vulnerable households must use the normal fault-reporting channels and that City Power did not maintain household medical-condition records.“City Power is not mandated to maintain records of individual customers’ or households’ medical conditions,” Mangena said.City Power also said it “does not provide specialised or preferential assistance to individual medically vulnerable residents or households”. The utility said generators could not be deployed to individual households, while identified medical facilities may receive alternative supply where operationally feasible and resources were available.If City Power does not know that a household contains someone who depends on electrically powered medical equipment, that information is not part of the response when there is a prolonged outage. While the ordinary fault-reporting system may tell the utility that the electricity is off, it does not tell them what the outage means inside any particular home.Johannesburg Water spokesperson Nombuso Shabalala said the entity’s mandate was to provide water and sanitation services and to deploy alternative water supplies during qualifying interruptions. She said the identification and coordination of broader social or medical support for vulnerable residents fell within the mandates of the relevant municipal and provincial health or social-service structures.No municipality can prevent every substation fire, burst pipe, cable fault, theft incident or infrastructure failure. The question is what happens when the failure continues and the people affected cannot simply wait. Those who can afford alternatives have more choices. Those who cannot are left relying on ordinary response systems even when the consequences inside the home are anything but ordinary.
