This applies to the stretch from the Nygårdsforsen power station to the Jäxbo bridge. According to Jenny Holmberg, press officer for Mälarenergi, staying at the site can be life-threatening.
– You can get stuck in the mud, which is like quicksand. You can fall and hit yourself and you can get stuffing material all over you. It is a place that should be avoided at the moment, she says.
When filling material collapsed on one long side at the power station during the strengthening work on Friday, Mälarenergi chose to empty the dam of water. When the dam was emptied on Monday, material collapsed on the other long side without any excavation work having been carried out.
That the danger is real, an expert on earth fill dams found out when he was going to do tests in the area.
Hear about when the expert got stuck in the quicksand-like mud in the clip.
