Penticton drinking water path

• Source & supply

  Okanagan Lake

  Penticton Creek

  Treated water feeds the municipal distribution system. Ellis Creek is used for agricultural/irrigation supply, not the potable plant blend.

  A 1986 Giardia outbreak traced to Penticton Creek drove the dual-source filtration plant that returned creek water to service only after full treatment.
