This decision has been made after a number of suspected arson attacks recently in Sweden, on facilities which were planned to accommodate refugees.
"Our focus now is a feeling of security, and safety. But I understand that it won't be possible to keep this a secret forever. But we want the people getting these accomodations ready to be able to do so in peace," social director Ewa Klingefors-Hedlund, told the station.
Umeå is preparing to receive 150 refugees at the moment.
Meanwhile, Halima, who has lived in housing for asylum seekers in Vänersborg, for nearly a year, is scared of fire there.
She told Radio Sweden's Somali department, "Of course, I'm worried that this will mean that refugees who have come to Sweden to gain sanctuary, and who don't have any resources whatsoever, will suffer in the future and be burned to death."
There are currently more than 8,000 accomodation facilities for refugees. Last week, three places which had been planned to house refugees temporarily were completely destroyed.
