Update

Greater Vernon Water will be rescinding it’s water source change.

GVW said the lake water quality had improved, and the Kalamalka Lake water source would be turned back on Thursday, April 17.

People who usually receive their water from Kalamala Lake had been supplied by the Duteau Crtreek source, and GVW said the people may notice a return to harder water with high alkalinity and pH when they return to the lake source.

GVW noted people may have see some cloudiness or sediment in the water after the source change. Anyone who experiences this was advised to run a cold water tap closes to where the water enters their house before reaching the hot water tank, home filtration systems, or aps with aerators. it was added that it was best to do this process using an outside tap.

— Original Story —

People that usually receive their water from the Mission Hill Water Treatment Plant are being supplied from a different source.

Greater Vernon Water shut down the Mission Hill plant Tuesday, April 8, as the rain and spring run-off in the Coldstream Creek watershed resulted in increased turbidity in Kalamalka Lake.

People usually supplied by the Mission Hill system were instead getting their water from the Duteau Creek Water Treatment Plant.

GVW noted water from Duteau Creek has lower alkalinity and pH when compared to the lake water, which may impact in-home water treatment systems or aquariums.

Water service from Kalamalka Lake would be restored once sample testing showed it was appropriate to get the system back online.

GVW and the Regional District of North Okanagan noted making the service change was “not ideal” as the storage levels in the Aberdeen Plateau reservoirs were already low.

GVW was on Stage 1 water restrictions as of Tuesday, and people were asked to conserve water as much as possible.
