For Immediate Release
November 10, 2016
The City of West Kelowna has lifted the Water Quality Advisory for the Lakeview System as testing has indicated the turbidity level has returned to below 1.0 NTU.
Flushing of the system is still underway and some users may notice discoloration. Signs will be posted in areas where water mains are being flushed; and residents are asked to minimize their water consumption if possible when signs are posted. Should residents notice discoloration after flushing is completed in an area, they are advised to turn on their cold water tap until it runs clear.
Flushing will continue for several weeks, weather permitting, and will be resumed in the spring if necessary.
Free water will continue to be offered at the Bulk Water Station at Asquith and Shannon Lake Roads until Friday, November 18.
The Water Quality Advisory, affecting approximately 4,000 connections in areas including Lakeview Heights, Boucherie Centre, Rose Valley, Shannon Woods, Tallus Ridge and Shannon Lake, was put in place in August due to higher than normal turbidity in the Rose Valley Reservoir, the supply source for Lakeview System.
The City of West Kelowna reminds Lakeview water customers that this system is unfiltered; and the provincial recommendation is that newborns and people with weakened immune systems consume water that has been brought to a running boil for one minute, or use a safe alternative source.
Provided For Reference Purposes
Originally issued: August 4 and 8 (re-posted August 15) and August 18 (updated August 25 and 30 and September 7, 9, 15, 16, 19 and 21 and October 6, 19 and 27)
WATER QUALITY ADVISORY FOR
LAKEVIEW SYSTEM IN WEST KELOWNA
Ongoing testing showed turbidity ranging between 0.8 and 2.2 NTU, between August 4 and November 10, 2016 and a Water Quality Advisory for West Kelowna’s Lakeview Water System continued during that time.
The advisory affected approximately 4,000 connections (11,000 customers) in neighbourhoods including: Lakeview Heights, Rose Valley, Boucherie Centre, Shannon Woods, Tallus Ridge and Shannon Lake. The City of West Kelowna continued to monitor daily, and advised the public that they would be informed as soon as the advisory could be lifted. An interactive map was provided to help customers determine if they were living in the water quality advisory area.
Residents living in the Westbank, West Kelowna Estates, Pritchard and Sunnyside Water Systems were not affected. Neighbourhoods not affected by the Water Quality Advisory included: Glenrosa, Westbank, Smith Creek, Gellatly, Green Bay, South Boucherie/Mission Hill/Sunnyside, Pritchard Drive/Jennings and Hitchner Roads, West Kelowna Estates/Bear Creek, those on the Casa Loma System, and areas of Westside Road within the municipal boundary.
Due to higher than normal turbidity, it was recommended that children, the elderly and people with weakened immune systems were to bring water to a rolling boil for at least 1 minute, or use an alternate, safe source of water. People in these categories were to boil water for uses such as: Drinking, brushing teeth, washing fruits and vegetables that were to be eaten raw, preparing food, mixing baby formula and making ice.
What Is Turbidity?
Turbidity guidelines are nationally established standards and are as follows:
Good (Less than 1 NTU) – No water restrictions are recommended.
Fair (1-5 NTU) - It is recommended that children, the elderly, people with compromised immune systems, and anyone seeking additional protection, use water that is brought to a running boil for one minute, or a safe alternative.
Poor (>5 NTU) - It is recommended that all users bring water to a running boil for one minute, or use a safe alternative.
As turbidity increases, bacteria, viruses and microorganisms can attach themselves to the suspended particles in water. These particles can interfere with disinfection by shielding the microorganisms from the chlorine.

What Caused the Turbidity?
Algae growth in Rose Valley Reservoir was greater than normal due to unusual weather in 2016, contributing to the higher turbidity levels. NTU levels had not been that high in the Lakeview System since 2008.
