Iqaluit Water Treatment Plant
City plant receiving gravity-fed Lake Geraldine raw water; UV and chlorination disinfection (filtration as designed); after 2021 hydrocarbon emergency events, plant has used tank-bypass operations while maintaining disinfection and real-time hydrocarbon monitoring.
Treated water is stored in above-ground reservoir cells and distributed by piped utilidor network plus trucked potable-water delivery to unpiped buildings. Arctic utilidors keep distribution lines above permafrost.
Health parameters meet Health Canada limits; turbidity above the 1 NTU typical target.
One or more parameters exceed a Health Canada drinking water guideline or turbidity target.
