Saskatchewan city of Prince Albert to lift boil water order after six weeks

PRINCE ALBERT, Sask. - The days of residents in Prince Albert, Sask., having to boil their drinking water are coming to an end.

Mayor Jim Scarrow told a business crowd Thursday that the boil water order would be lifted on Friday.

He said information on how residents can flush out their own water systems would also be arriving in mail boxes soon.

The flushing is recommended by the Prince Albert Parkland Health Region before residents drink from the tap again.

The order began almost six weeks ago when testing revealed harmful parasites in the drinking water.

Traces of giardia and cryptosporidium got into the water supply when a mechanical failure allowed untreated water from the North Saskatchewan River to enter the water treatment plant.

Once the plant began producing clean water again, the province approved the city to begin cleaning the entire system.

The flushing began late last month and was completed this week ahead of schedule.

The city plans a news conference Friday morning to make the official announcement.
