A boil water advisory for the West Park and West Lake neighbourhoods was lifted Wednesday after several clear samples were produced and consultation with Alberta Health Services.
Residents in many neighbourhoods reported little or no water pressure at approximately 9:30 p.m. Tuesday. Service was restored by 10:35 p.m. to all the affected areas, and crews flushed the lines and took samples to ensure water quality.
The city’s environmental services department has determined a power failure in the control system resulted in a total shut down. Pumps at the booster station and water treatment plant were manually turned on, and water pressure was restored within 20 minutes.
After a disruption of this nature, lines can contain sediment. Though the water is safe, residents are encouraged to run their taps for five minutes to flush their lines.
