Residents of Perth, Australia, have an unusual culprit to blame for their Sunday evening plans getting canceled: a dreaded “fatberg” causing wastewater to overflow.

Three things to know:

1. Fatbergs are massive globs of congealed cooking fat, grease and other waste often held together by wet wipes and rags that create huge water blockages in sewer systems and can be tedious and expensive to remove.
2. The blockage was detected near a Perth arena mere hours before Canadian musician Bryan Adams’ sold-out show was set to take place.
3. Workers were called to help clear up the fatberg, but were unable to resolve it before the start of the show. Water authorities warned of wastewater flowing into the venue, forcing organizers to cancel the show and upsetting the many fans who had received no communication and had been waiting for entry.

Why do fatbergs happen?

Waste management workers have been dealing with people using their toilets like trashcans for decades. But the booming wipes industry has posed a new challenge in keeping pipes and waterways clean.

And it can cost taxpayers. NPR reporting from 2017 found that fatbergs were costing London’s water provider more than $1.3 million a month to remove.

Sewer managers say it’s best to throw wet wipes in the garbage. And Australia’s Water Corporation says cooking oils and fats can harden in pipes — instead of pouring down the drain, put it in a container and freeze it until trash day.
