As clean water once again flows from taps in the city of Winnipeg, members of a nearby First Nation community say they remain under a boil water advisory that's been in effect for nearly two decades.

Some members of the Shoal Lake 40 First Nation were in Winnipeg earlier this week to protest their plight. Winnipeg recently lifted its three-day warning after water tests turned up negative for E.coli. But Shoal Lake residents say their water troubles have yet to be addressed.

Chief Erwin Redsky, of the Shoal Lake 40 First Nation, says his people are no closer to turning on their taps now than they were when their water supply was found to be contaminated in 1996.

Residents in the Shoal Lake community have been boiling their water or importing it from other towns on a weekly basis, even as a nearby aqueduct pumps drinkable water out to Winnipeg.

"It's very difficult," Redsky told CTV New Channel on Sunday. He added that there has been "no progress to date" with clearing up the issue.

The Shoal Lake 40 First Nation sits on a man-made island established in the early 1900s during the construction of the Winnipeg aqueduct.

Erwin says experts have examined the Shoal Lake water problem, but it's been deemed too expensive to fix.

"This should not be happening in (2015)," Redsky said. "All Canadians should have clean water to drink."

Winnipeg's boil water advisory lasted only a few days after a handful of tests showed possible traces of E.coli in the water supply. Later tests came back negative.
