Drinking Water Quality and Supply

From source to sink

Where Penticton water comes from

A plain-language tour of the lakes, rivers, or wells that feed Penticton, the plants that clean the water, and how it reaches kitchen taps. Lab grades for hardness, lead, and pH live on the water quality page.

Deep dive for households

Penticton drinking water starts as surface water (rivers, lakes, or reservoirs). The named sources on the utility record are Okanagan Lake, Penticton Creek. That is the water that eventually reaches kitchen taps after treatment, not a separate bottled brand.

Water is cleaned at Penticton Water Treatment Plant before it enters city pipes. Dual-source plant (commissioned mid-1990s) beside Penticton Creek. Blends Okanagan Lake (pumped) and Penticton Creek (gravity) in variable proportions; lake water typically dominates (~90% in city drought-planning averages).

After treatment, water moves through pumps, storage, and underground mains to reach streets and buildings. Treated water feeds the municipal distribution system. Ellis Creek is used for agricultural/irrigation supply, not the potable plant blend.

One detail that makes Penticton water feel local: A 1986 Giardia outbreak traced to Penticton Creek drove the dual-source filtration plant that returned creek water to service only after full treatment. Lab grades for hardness, lead, and pH sit on the city water quality page; this overview is about the route the water travels.

Where it starts

Surface water

Rivers, lakes, or reservoirs, not underground wells as the main draw.

Named source waters

  • Okanagan Lake
  • Penticton Creek

Treatment plants

These are the buildings that filter and disinfect water before it enters city pipes.
