The blockage is thought to be more than a metre high and weigh about 300 tonnes. It is expected to take over a month to remove.
Fatbergs are caused by non-biodegradable waste, such as wet wipes and cooking oils, being flushed into the waste system, creating a solid, immovable mass.
Authorities stated: “The problem is that unlike toilet paper, wipes and other unflushables, including nappies and sanitary products, don't break up or dissolve, so they easily get stuck in drains and sewers and then attach on to cooking oil and grease to create a fatberg.
Our advice is to always leave leftover cooking fat to cool, before disposing of it in the bin and to stick to only flushing the three P's (pee, poo and toilet paper) and bin anything else.”
