800 ton fatberg removed from sewer in Cardiff Bay

A fatberg weighing the equivalent of 133 African bull elephants has been removed from a sewer in Cardiff Bay.

The blockage was caused by a buildup of fat, oil, grease and other items which Welsh Water say have been "illegally put into the sewer". Specialist equipment had to be brought in to remove the fat from a sewer beneath Mermaid Quay.

The fat clean up is part of a £2 million investment project to repair the sewer running under Stuart Street and Bute Street.

Welsh Water's Managing Director of Wastewater Services said the work had been "challenging" and that they had been working with businesses in Mermaid Quay to make sure fat was being disposed of properly.

With 800 tons of fat removed so far, the work is yet to be finished. The project continues in the New Year.
