About 10 properties in the G&M trailer park, near Highway 5 and Shuswap Road, are being surrounded by water coming up from the park's underground septic field, turning Mario Milanese's yard into a swamp of sewage.
"It's kinda of greenish, slimy, with kinda a skim of oil on top," said Mario Milanese.
He says the sewage has turned his yard into a swamp and is seeping under his mobile home.
Residents first started noticing a problem three weeks ago, says neighbour Natasha Araneda.
"It's pretty terrible. It smells," said Araneda.
She and her 3-year-old daughter have moved out and are now staying with relatives.
Residents say Health Canada told them to leave
Milanese says on Monday, the owner of the trailer park finally brought in trucks to drain the septic field — but not before an official from Health Canada knocked on his door and said his home isn't safe to live in.
"They are saying we have to leave. We should get out of here. It's not safe to be here."
Milanese says he wants to leave, but doesn't have a place to go. He says the owner has refused to pay for hotels for residents.
"I don't know what to do, this is the problem, I don't know where to go. I don't know if I should go to hotel and hopefully get reimbursed," he said.
The manager of the trailer park did not return repeated calls from CBC News.
