Residents across several South London postcodes have been left without water or facing low pressure for four days after a burst pipe in Dulwich disrupted supply to thousands of homes.
The issue, which began on Tuesday evening (February 11), has affected properties in SE19, SE20, SE23, SE26, SE27, and SW16, including Crystal Palace, Sydenham, and surrounding areas.

Thames Water Fixes Leak but Disruptions Continue
While Thames Water has confirmed that the burst pipe has now been repaired, some customers may still experience low water pressure or intermittent supply, particularly during high-demand periods.

A bottled water station has been set up at Sainsbury’s in Southend Lane, SE26 4PU, for those still without running water.
Frustration Grows Among Residents
Locals have expressed frustration over the prolonged outage, with many making multiple trips to collect bottled water for themselves and their neighbours.
Sydenham resident Martin Webb, 47, spoke at the emergency water station:
“It’s the first time I’ve been today, but I’m coming back as I’m assisting other people. The water is off and on at the moment. Since I’ve been living in the area, there has been a big problem with the water.”
Catford resident Fiona Morrison added:
“We’ve had no water for three days. At first, I thought it had frozen, but when it continued, I realised it was more serious. I didn’t know there was bottled water here—I just saw it on my way to work.
Thames Water’s Response
A Thames Water spokesperson apologized for the disruption, stating:
“We have now fixed the leak and are working hard to flush the system and do final checks to fully restore supplies.
Some additional customers may experience no water overnight, but we’re working to limit the time you’ll be out of supply.”
Thames Water has also:
- Diverted water from other areas to restore supply
- Ensured that schools and hospitals have alternative water supplies
- Contacted vulnerable customers who are medically reliant on water to provide support
Ongoing Concerns
Despite reassurances, many residents remain concerned about ongoing supply issues, with some reporting that the area has had longstanding water pressure problems.
