Lake Geraldine (Geraldine Lake)
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.
Single-lake arctic capital supply: Lake Geraldine sits about 1 km north of the city behind a dam that stores meltwater/precipitation. 2021 fuel-related taste/odour emergencies drove permanent monitoring and bypass upgrades; city posts ongoing water-quality updates.
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.
