A collapsed 19th century culvert that has caused a significant sinkhole in a south Wales village, and which was previously damaged in 2009, has raised questions over the resilience of ageing infrastructure in the face of climate change.

The culvert in Pant, Merthyr Tydfil, is believed to have collapsed after two landslides triggered by Storm Bert last month sent debris crashing through it.

Following its collapse, a large ground collapse on the estate was reported to emergency services on Sunday (1st December 2024).

Emergency work to stabilise the ground collapse has included forming a dam on the brook so the council’s engineering team can install pumps to over-pump the water and stop it flowing through the culvert. The council has appointed Edwards Diving Services to carry out the stabilisation work. Sprayed concrete lining works by GSSL Gunite and Shotcrete Services Ltd.
