Deep dive for households

Nelson drinking water starts as surface water (rivers, lakes, or reservoirs). The named sources on the utility record are Five Mile Creek, Anderson Creek (incl. Fell Creek), Selous Creek. That is the water that eventually reaches kitchen taps after treatment, not a separate bottled brand.

Water is cleaned at Mountain Station Water Treatment Facility before it enters city pipes. As of 2023 all sources consolidate here: sedimentation in historic reservoir, UV, and chlorination (sodium hypochlorite).

After treatment, water moves through pumps, storage, and underground mains to reach streets and buildings. Five Mile supplies ~88% via a 1927 pipeline; Anderson and Selous supplement peak summer demand. Anderson booster lifts water ~100 m to Mountain Station.

One detail that makes Nelson water feel local: Five Mile Creek is named for CPR paddle-wheeler mile markers on Kootenay Lake; its 1927 French-steel supply main still anchors the system. Lab grades for hardness, lead, and pH sit on the city water quality page; this overview is about the route the water travels.
