Supply and treatment

How Prince George draws, treats, and distributes drinking water, from municipal and utility publications. Chemistry grades above come from separate parameter records; this section does not invent plant lab figures.

Source type

Groundwater

Research confidence: high

Source waters

  • Nechako River valley aquifers (GUDI wells)
  • Fraser River valley aquifers (GUDI wells)

Treatment plants

  • Distributed well chlorination facilities (no central filtration plant)

    Multiple groundwater wellfields (including major Nechako radial-collector wells such as PW605/PW601/PW660) disinfect with on-site generated sodium hypochlorite before distribution; soil/gravel provides natural filtration.

Distribution

Seven well locations, nine booster stations, and about fifteen reservoirs serve the main city system covering most developed areas. Seasonal Fraser-bank wells add summer capacity; one southwest well serves a separate local system.

Health parameters meet Health Canada limits; turbidity above the 1 NTU typical target.

Health parameters meet Health Canada limits; turbidity exceeds the typical 1 NTU aesthetic target.
