What is a "fatberg"? What causes it to form? How is it
eliminated?

a very large mass of solid waste in a sewerage system, consisting especially of congealed fat and personal hygiene products that have been flushed down toilets.

They are caused by oil, grease and fat being poured down sinks, where they congeal and stick to sewer walls. Once this build-up has occurred, other waste that enters the sewer can often stick to the fat

The broken up fatberg pieces are then removed from the pipe by manual excavation, powerful vacuumation tanker units
