The Boil Water Notice for the Sunnybrae Water System issued on April 11, 2019 has been rescinded effective May 23, 2019.
Recent water quality tests have confirmed that turbidity levels in the Sunnybrae Water System's drinking water supply have returned to acceptable levels.
As required by Interior Health, the precautionary notice was issued to users of the system due to higher than normal concentration of particles in the water. This is known as turbidity, which makes the water appear murky. It can also cause interference with the water treatment plant's disinfection process. Particles in the water can potentially shield bacteria from the ultraviolet (UV) and chlorination processes used to ensure the supply is safe for public consumption.
Turbidity is dictated by external conditions, including how fast the snow melts, how fast the water is flowing and how much sediment is being picked up. As a result, higher levels of turbidity are more common during spring freshet.
Turbidity is measured in units known as NTU and when the turbidity of the water exceeds 5 NTU, a Boil Water Notice must be issued. The Sunnybrae Water Treatment System monitors turbidity levels continuously, 24 hours a day. Testing of the Sunnybrae Water System has confirmed turbidity levels have returned to levels below 5 NTU.
