Residents in the remote Arctic community of Sachs Harbour, N.W.T., are still having to boil their water seven months after chlorination pumps failed at the local water treatment plant, which continues to be plagued by problems.

Nunakput MLA Jackie Jacobson has called on the territorial government to fix the water plant so that the boil-water advisory can finally be lifted in the hamlet of 122, located on Banks Island.

"I don't care who's to blame," Jacobson told CBC News on Tuesday.

"I just want to ... address this issue, to get it servicing the people of Sachs for safe drinking water."

Sachs Harbour's boil-water advisory was issued July 10 by territorial health officials, who said there were problems with the water plant's chlorination pumps.

Jacobson said the $5-million water treatment plant could not cope with the harsh northern environment, resulting in a number of breakdowns since the facility was installed in 2005.

"[There have been] steady problems with the plant: either the power, or the piping freezing up," he said.

Duane Fleming, the N.W.T.'s chief environmental health officer, said while the plant has had problems, the chlorination pump issue has since been fixed.

It's now up to hamlet officials to use the facility and test the water before the advisory can be lifted, Fleming said.

"We need the community to be using the water treatment plant and for the community to be complying with the required sampling and testing requirements," he said.

But Raymond Kaslak, Sachs Harbour's senior administrative officer, has said the hamlet still has problems with faulty intake pipes at the plant.

After Jacobson brought his concerns to the N.W.T. legislature on Monday, Municipal and Community Affairs Minister Robert McLeod said his department is working on problems at the water plant.

"Right now, we're working with our partners at Public Works and Services … [on] identifying a solution for the intake pipe to the water treatment plant," McLeod told the legislative assembly on Monday.

"We're at the design-approval stage right now, and hopefully, I'll be able to provide the member [Jacobson] with more information when that becomes available."

Jacobson said the territorial government has pledged $1 million to fix the faulty intake pipes, adding that he wants the repairs done by this summer.
