Deep dive for households

Whitehorse drinking water starts as groundwater from wells. The named sources on the utility record are Riverdale / Selkirk Aquifer (Yukon River-recharged groundwater), Schwatka Lake (historic primary source; potential future backup after treatment upgrades). That is the water that eventually reaches kitchen taps after treatment, not a separate bottled brand.

Water is cleaned at Selkirk Pumphouse before it enters city pipes. Central Riverdale facility where production-well water receives sodium hypochlorite disinfection before distribution; currently the sole municipal treatment step.

After treatment, water moves through pumps, storage, and underground mains to reach streets and buildings. Municipal piped system is supplied from roughly seven Riverdale Aquifer production wells. Water is chlorinated at Selkirk Pumphouse and monitored continuously there plus weekly at many distribution sites. Some residents use private wells or trucked tank water outside the piped system.

One detail that makes Whitehorse water feel local: City switched from Schwatka Lake surface water to exclusive groundwater by 2010. Recent GUDI (groundwater under direct influence of surface water) findings are driving multi-barrier treatment upgrades that could again allow Schwatka Lake use as a redundant source. Lab grades for hardness, lead, and pH sit on the city water quality page; this overview is about the route the water travels.
