The "best" was found in a pumping station that handles wastewater.

- It is not uncommon for grease to stop due to grease, but it is because of a lump of this size is not common, says Per-Arne Hermansson, acting press contact at Mälarenergi.

How did it "arise"?

- It is fat that comes from when people, for example, flush the frying pan straight down the sink. When you rinse it out, the fat is hot, but it solidifies quickly down the drain and so these lumps build on everything because, says Per-Arne Hermansson.

One million at the fat stop

He has not seen the lump with his own eyes, but was told that it was almost a meter in diameter.

- We put a million SEK each year on stoppages in sewers that are due to fat. This is significant money, so we wish that more wipes from food grease from the frying pan with paper towels and tosses in the household garbage instead or if you have a deep fryer, that you pour the frying oil on a pet bottle and hand it in for recycling.

What happened to the lump now?

- You, the only thing I know is that it is not left, but exactly where it was taken I do not know, says Per-Arne Hermansson.
