A major burst water main in Canonbury, Islington, sent water pouring into several streets on the evening of Sunday 10 July, forcing around 30 residents to leave their homes and prompting a multi-agency emergency response. According to the original report, houses on Canonbury Street, Essex Road, Elmore Street, Halliford Street and Ecclesbourne Road were affected, with floodwaters reaching roughly 40 cm deep in places and disruption expected to continue into the following day.

The London Fire Brigade described the event as a protracted incident and mobilised a substantial response. “Ten fire engines and around 70 firefighters are dealing with flooding in the area around Canonbury Street in Islington,” a brigade spokesperson said, noting crews used flood barriers and sandbags to protect properties. Firefighters came from a number of local stations and worked through the night to limit damage and make properties safe, with video footage showing doorsteps and vehicles partially submerged.

Emergency services said the pipe involved was large — reported as a 36‑inch main — and the scale of the failure generated more than 20 emergency calls after 10pm. The Metropolitan Police and Islington Council joined the response, closing roads and urging drivers and pedestrians to avoid the area while crews carried out safety checks and traffic management.

Thames Water confirmed engineers were on site to locate the damaged section and work to stop the flow. The company said in a statement that crews were investigating the fault and would remain at the scene to repair the pipe and restore services; editorially, that is Thames Water’s account of progress while repairs are ongoing. Some addresses reported no water or low pressure as crews isolated supplies to protect the network while work continued.

Islington Council said it was providing assistance to those displaced, including temporary accommodation where needed, and public-health and safety messages were issued to residents. Council officers and emergency workers advised people not to drive through floodwater, to avoid the cordoned area and to follow instructions from on-scene crews as recovery proceeded.

Local roads and services were expected to face continued disruption into Monday as engineers excavated to reach the damaged pipe and make permanent repairs. Industry experience suggests work on a large trunk main can take many hours or longer depending on the extent of the damage, reinstatement needs and any associated utilities impacted by the repair works.

Investigations into the cause of the failure were under way while recovery teams prioritised getting homes and roads back to normal. Authorities said they would update residents as repairs progressed and urged anyone affected to contact Islington Council or Thames Water for help with housing or water-supply issues.
