Homes across south-east London are facing a fourth day without proper water supply as Thames Water struggles to repair a series of burst pipes in Dulwich and Sydenham.
Customers in parts of both areas have dealt with low water pressure or complete supply interruptions since Saturday, October 11, with the utility company warning that repairs are likely to take several more days.
What is happening
Thames Water said its teams worked through the night into today (October 14) and have installed additional equipment in an effort to stabilise the water network. Water tankers are also being used to pump extra water into the system.
However, several bursts and leaks remain to be fixed. Crews are currently repairing burst pipes on Sydenham Rise, near the Horniman Museum. Once those repairs are complete, traffic management will move to Dulwich Common so another repair can be carried out. Teams will then tackle a leak at the junction of Lordship Lane and London Road, at Wood Vale, for the final repair. One burst on Lordship Lane has already been fixed.
In an update at 7.33am today, Thames Water said: “Our teams have been working through the night to make significant progress. We were made aware that some customers were potentially still affected with supply interruption. We’ve managed to install additional assets in the area to ensure that the network is more stable.”
Who is affected
The problems centre on Dulwich and Sydenham in south-east London — affluent, densely populated suburbs where thousands of households depend on the same ageing Victorian-era pipe network. Thames Water said customers in high-rise buildings may continue to experience lower water pressure during periods of high demand while the work continues.
For residents, four days of intermittent supply is more than an inconvenience. It disrupts everything from morning showers and school runs to cooking, cleaning and caring for elderly relatives. Those with medical needs that depend on a reliable water supply face particular difficulties.
Traffic disruption
The repair work is also causing significant disruption on the roads. Temporary three-way traffic lights and pedestrian crossing arrangements are in place on Sydenham Rise, opposite the Horniman Museum. Thames Water has warned people travelling through the area to allow extra time for their journeys.
As crews move between repair sites — from Sydenham Rise to Dulwich Common, then to the Lordship Lane and London Road junction — the traffic management will shift with them, meaning drivers in the wider Dulwich and Sydenham area should expect ongoing delays.
Thames Water under pressure
The extended outage adds to the mounting scrutiny on Thames Water, the UK’s largest water company, which has faced criticism over its infrastructure investment, leakage rates and financial health. Burst pipes are a symptom of an ageing network, and critics argue that years of underinvestment have left London’s water mains vulnerable to exactly this kind of cascading failure.
The company has not said when full normal service will resume, beyond warning that repairs will take “a few days to complete.” For residents now entering a fourth day of disruption, that timeline offers limited comfort.
What to do if you’re affected
Thames Water advises customers experiencing supply issues to check its website for the latest updates on their postcode. Those with additional needs — including medical requirements — should contact the company directly to register for priority support during outages.
If you have no water at all, check whether your neighbours are affected too (which suggests a network issue rather than a problem with your own plumbing), and report it to Thames Water. Keep some bottled water on hand for drinking and cooking until the supply stabilises.
London Streets has been tracking disruption across the capital today, from road closures to police operations. We will update this article as Thames Water completes its repairs.
