Residents of Gwaelod‑y‑Garth woke to scenes of devastation after a torrent of mud and floodwater swept through the village yesterday evening, leaving several homes damaged and prompting multiple evacuations.
Emergency response and investigations under way
South Wales Police, the fire service and Cardiff Council deployed teams to support people affected by the incident. Officers from several council departments — including highways, flood risk management, transport, waste management and housing — attended the scene to assist with immediate needs and begin clean‑up work.
The Health and Safety Executive (HSE) has confirmed it is carrying out an investigation and is working alongside South Wales Police. In a statement the regulator said a notification was received the previous evening and inspectors have visited the site to begin enquiries.
"We were made aware of the incident yesterday evening and liaised with South Wales Police and the emergency response team. We have attended the site and investigations into the incident have begun. We are working with South Wales Police in commencing an investigation."
Extent of damage and support for residents
Cardiff Council has provided figures on the immediate human impact:
- 15 properties affected by flooding;
- 13 homes evacuated by the fire service;
- Temporary accommodation arranged for at least one family, with support being arranged for another household.
Council housing officers continue to liaise with those displaced and some families have made private arrangements. Local cleanup teams remain on site this morning as the cause of the flood is probed.

Questions remain over cause
A number of agencies have been contacted as part of the inquiry into what triggered the flooding. Journalists have sought comment from the quarry operator Breedon, Natural Resources Wales, the Mining Remediation Authority and the Welsh Government, and several of these bodies are reported to have representatives in Gwaelod‑y‑Garth this morning.
Images from the scene show gardens and driveways under thick layers of mud, and residents have described the emotional and material toll of the event. Local officials say cleanup and recovery work will continue while investigators attempt to establish the sequence of events that led to the sudden inundation.
For residents seeking assistance, the council advises contacting its housing team. Anyone with information that might assist the ongoing investigation is asked to make contact with South Wales Police.
The situation remains fluid and InfoRadar will publish updates as more details become available from the investigating authorities.
