Cardiff Bay Sewer Blocked by Fatberg
Repairs to a sewer damaged by a fatberg in Cardiff Bay are set to begin.
Dŵr Cymru (Welsh Water) said the £2m work was needed after the sewer was blocked by a build-up of fat, grease and oils. It said disruption would be “kept to a minimum” during the five-month repairs.
Bosses said they will liaise with businesses to ensure they have the right equipment to dispose of waste correctly to avoid similar problems in the future.
Footage of the fatberg, filmed in June, shows how substances poured down drains have hardened to line the sides of the sewer. It will be removed as part of a “deep excavation” at Mermaid Quay, between Salt Bar and The Dock pub, ahead of repairs on the Victorian sewer.
Welsh Water warned there could be issues with “odour” during removal of the blockages. The sewer, which runs under Bute Street and Stuart Street in Mermaid Quay, was previously a large-capacity tidal sewer intercepted by the Bute Town Road Tunnels in the 1990s.
Steve Wilson, Welsh Water’s director of wastewater services, said:
“We always ask our customers to be careful about what they dispose of down the drains so that our sewers continue to operate effectively.”
He said work would be carried out in phases and put on hold during busy periods such as the autumn school holidays and run-up to Christmas.
