What Makes Coquitlam Town Centre's Water Unique?
Local geology and source profile
Coquitlam Town Centre (the commercial and residential hub of Coquitlam, centred on the Coquitlam Centre shopping mall and Lincoln SkyTrain station — one of the Metro Vancouver region's fastest-growing transit-oriented development corridors with extensive new high-rise condominium construction) receives its drinking water from the City of Coquitlam, drawing from Metro Vancouver (GVWD) — with the Town Centre sub-zone receiving predominantly the softer western Metro Vancouver supply via the Burnaby transmission corridor. Water is treated at the Seymour-Capilano Filtration Plant using ozonation, biofiltration, UV disinfection, and chloramination, fully meeting the Guidelines for Canadian Drinking Water Quality (GCDWQ). Hardness in the Coquitlam Town Centre zone is 32.5 mg/L (1.9 gpg) — classified as soft by Health Canada.
Coquitlam Town Centre's 32.5 mg/L — matching the adjacent Coquitlam West sub-zone (31.5 mg/L from batch 15) — confirms the western Coquitlam supply corridor's predominantly soft Capilano and Seymour watershed character. This stands in contrast to the eastern Coquitlam and Tri-Cities corridor (Port Moody 90.5 mg/L, Coquitlam City 87.5 mg/L from batch 4) which draws more from the harder Coquitlam Lake reservoir. The Town Centre's position on the western side of the Lincoln SkyTrain corridor places it within the softer western supply distribution zone.
With 32.5 mg/L of hardness, Coquitlam Town Centre residents — particularly in the area's rapidly expanding condominium towers — are essentially scale-free. Appliances, kettles, and plumbing require almost no descaling maintenance. The City of Coquitlam provides water quality information at coquitlam.ca.
Geology & Source: Supplied by City of Coquitlam from Metro Vancouver (GVWD) via the western distribution network — the Coquitlam Town Centre sub-zone near Lincoln Station receives very soft supply at 32.5 mg/L (1.9 gpg), consistent with the western Coquitlam soft-water corridor.
