Residents in Wandsworth have been suffering with low water pressure for more than two weeks after a huge leak on Wandsworth High Street.

Thames Water has issued an apology to the affected people in the Putney and Wandsworth areas, specifically SW11, SW15, and SW18.

Engineers have been “working round-the-clock” to resolve the issue, but the company says the repair has been complex, and full water pressure is yet to be restored.

Road closures on Wandsworth High Street are still in place and Thames Water claims the closures have been put in place with input local authorities to minimise traffic disruptions.

The issue was first reported on October 20, when Thames Water engineers noticed water emerging on Wandsworth High Street.

Thames Water explained that there are four water pipes running along the street, including a large 36-inch trunk main, which made it hard to identify the source of the leak.

Over the following 48 hours, crews isolated each pipe by shutting off water flow, eventually confirming that the leak originated from the trunk main on October 22.

Due to the size and location of the pipe, they needed to coordinate alternative water supply routes across their network, using tankers and diverting water to sustain local demand.

Once the water supply to the damaged main was shut off on October 24, it took three days for the pipe to drain sufficiently for repair work to begin.

By October 28, Thames Water engineers gained full access to the damaged section, allowing them to assess the situation and outline repair steps.

Since then, Thames Water claims its teams have been working nonstop to solve the problem.

Low water pressure remains an issue for some residents, particularly those in multi-storey buildings requiring additional pressure for water to reach higher floors.

Thames Water is sourcing water from other parts of their network and using tankers to pump additional water into local pipes.

Even now customers are still experiencing lower pressure during peak times – typically in the early mornings and evenings on weekdays.

Thames Water estimates that the repair will be completed within the coming week and pressure will gradually return to normal as they reintroduce water flow.

Thames Water has also been in regular communication with local councillors, residents, and businesses, sending letters and providing support where needed.

For those requiring further assistance, Thames Water advises customers to call 0800 316 9800, referencing BB 00833577 for any water supply concerns related to this incident.

Thames Water has apologised for the prolonged inconvenience and assures residents that their teams are committed to restoring full service as soon as possible.
