Repair teams make headway after widespread burst mains left thousands without water
Engineers working for Thames Water reported significant progress overnight after multiple burst mains caused large-scale water outages across east London and parts of Essex. Around 10,000 customers were affected by no supply or low pressure since the weekend, and many residents queued for hours to collect bottled water amid high temperatures this week.
In an update posted on its website on Thursday morning, Thames Water said its teams had completed three repairs and had begun carefully reintroducing water into the network. The company said higher pressures and restored supplies reached "further customers overnight" as the network stabilised.
“Good progress continues to be made in the area, with teams continuing to work on repairing the broken pipes and introducing water into the area where possible... We’re continuing to work towards all customers being back in supply by tomorrow (Friday), many will return sooner and this will depend on how quickly the network recovers.” — Thames Water (website statement)
The utility confirmed repairs had been completed on the following roads:
- High Road
- Daisy Road
- Chigwell Road
Thames Water said its engineers carefully reintroduced water to the network after the repairs, which resulted in increased pressure and restored service to a growing number of customers. The company added that tankers and crews remained on site to ensure the recovery proceeded "as quickly and safely as possible."
Support measures for vulnerable customers
The statement emphasised support for customers most affected by the outage. Thames Water said bottled water deliveries were being prioritised for those registered on its Priority Services Register and that bottled water stations would be available to the public. The company pledged to advise on opening times via its website.
Local residents who had been without supply for extended periods were explicitly acknowledged in the update: Thames Water said it recognised some customers "have been without water for a long time" and confirmed continued efforts to provide support while repairs were under way.
| Item | Detail |
|---|---|
| Estimated customers affected | ~10,000 |
| Completed repairs | High Road, Daisy Road, Chigwell Road |
| Expected full restoration | By Friday (subject to network recovery) |
| Support provided | Bottled water deliveries and bottled water stations; tankers on site |
While the company’s update offered a short-term timetable, it also made clear that the timeline depended on how quickly pressures and flow stabilised across the affected network. The rolling reintroduction of water means some households would have supply before others, determined by local recovery rates.
The outage highlights the operational challenges water companies face when several mains fail in a concentrated area, particularly during periods of hot weather when demand rises and residents rely on bottled water for drinking and cooling. Thames Water’s use of tankers and bottled water stations follows common contingency measures for major supply interruptions.
Residents affected by ongoing low pressure or no supply were advised to consult Thames Water’s website for the latest updates on bottled water station locations and timings, and to check whether they are on the Priority Services Register for direct assistance.
Thames Water’s update did not provide a cause for the multiple bursts in the statement published on Thursday morning, nor did it specify the number of engineers or tankers deployed. The company focused on the progress of repairs and the commitment to restoring supplies to all customers as quickly as the network allows.
Local authorities and emergency services often monitor such incidents to assess broader community impacts, especially where hospitals, care facilities and other critical services may be affected. Thames Water’s message underlined their operational priority — repair the mains, reintroduce water carefully, and keep vulnerable customers supplied while restoration continues.
