The UK is currently experiencing its third heatwave of the year, with temperatures across the country soaring. While many are contending with hosepipe bans, an additional challenge has emerged in recent weeks: a notable increase in burst water pipes, particularly evident in Suffolk. Areas such as Ipswich, Framlingham, and Stutton have reported significant incidents, leading to localised flooding and disruption to water supplies.
The extreme weather conditions are playing a crucial role in this surge. Dr Geoff Darch, Anglian Water's head of strategic asset planning, explained that the high demand for water combined with the drying of soil is a primary cause. As the ground dries out, it shifts and moves, placing considerable stress on the underground pipe network. This movement can cause pipes to crack or fittings to fail, resulting in leaks and bursts.
One dramatic example occurred on Monday when Essex & Suffolk Water responded to reports of low water pressure on Saxstead Road in Framlingham. A video from the scene showed the severity of the leak, which had caused the road surface to crack and lift. A week prior, emergency services were called to Crown Street in Ipswich after a burst pipe led to extensive flooding, affecting a local burger bar and leaving nearby homes without water or with significantly reduced pressure. Similar issues were reported in Stutton, near Holbrook, leading to the closure of Manningtree Road for repairs.
A spokesperson for Essex & Suffolk Water confirmed that similar issues can arise during extreme cold in winter, as the ground hardens and shifts. However, they acknowledged an increased number of bursts recently due to the sustained hot temperatures. Cath Jones, head of household relationship management at the Consumer Council for Water, highlighted that the changing climate is putting greater pressure on water companies' infrastructure, exposing weaknesses during prolonged periods of hot weather. She stressed the importance of companies preventing bursts and fixing them promptly, especially given the significant investment from customers through bill increases.
Beyond the immediate impact of the heat, ageing infrastructure is also a contributing factor. Malcolm Owers, a 65-year-old farmer from Pettaugh, near Stonham Aspal, recounted how his village has suffered from a burst pipe along the A1120 for the past three months, a section that also burst in 2022. An Anglian Water spokesperson confirmed they are working to replace pipes in the area that are nearing the end of their 'useful life', acknowledging that this old pipework has led to ten bursts in the last five years, causing intermittent low pressure or loss of supply for residents.
