Heavy rains and flooding on Pasqua First Nation northeast of Regina are making a long-standing mould problem worse.

Some people who live on the reserve say basement flooding is now presenting a health hazard and they should be eligible for disaster assistance.

Richard DuBois's home is one of 26 on the reserve that have taken in water and have been damaged.

He's pulled furniture, mattresses and household items out of his flooded basement and while cleaning up, he's found mould.

DuBois said he's worried other people on the reserve may suffer health effects.

"You know I just feel sorry for the little ones and the elder people who can't get around that well and they have to breathe that in," he said. 

DuBois wants the community declared a disaster zone, so people can apply for assistance.

Band councillor Todd Peigan, who is in charge of the housing portfolio, said even before the recent heavy rains, there were 92 houses on the reserve that had mould problems.

After several weeks of rain, there are now 110 problem houses, he said.

"The dollars that we get every year just cannot resolve the expenses that are going to be incurred," he said.

If the federal government doesn't step in, offering disaster assistance, the problem will only get worse, Peigan said.

Pasqua First Nation is about 80 kilometres northeast of Regina.
