Burquitlam Water Hardness & Quality Report (2026)

Burquitlam's drinking water is supplied through the Metro Vancouver (GVWD) regional network — drawing from the Capilano, Seymour, and Coquitlam Lake watersheds through the Burnaby–Coquitlam transmission infrastructure. Water is treated and distributed fully meeting the Guidelines for Canadian Drinking Water Quality (GCDWQ). Hardness in the Burquitlam sub-zone is 55 mg/L (3.2 gpg) — classified as soft by Health Canada, consistent with the Metro Vancouver soft mountain supply with some Coquitlam Lake blending in the Burnaby–Coquitlam boundary distribution.

Burquitlam (a rapidly intensifying transit-oriented neighbourhood at the Burnaby–Coquitlam border near Clarke Road and Austin Avenue — the area around the Burquitlam SkyTrain station on the Evergreen Extension, experiencing dramatic densification with new high-rise towers and mixed-use development along the Como Lake corridor, centred on the historic Burquitlam community at the junction of Burnaby North and Coquitlam west) sits in a Metro Vancouver distribution sub-zone that appears to receive a blend of the soft Seymour-Capilano supply (15–35 mg/L range) and the harder Coquitlam Lake supply (87–94 mg/L). The 55 mg/L at Burquitlam is consistent with a mixed supply, harder than the Maillardville (54.5 mg/L) and softer than the eastern Coquitlam zones (87–94 mg/L).

With 55 mg/L, Burquitlam homes are essentially scale-free — occasional kettle cleaning every three months is adequate. Hot water tanks have an excellent operational lifespan. The City of Coquitlam and City of Burnaby provide water quality information through their municipal websites. Health Canada lead precautionary guidance applies to pre-1975 properties in the established Burquitlam residential area; new condo and apartment towers in the rapidly redeveloping Burquitlam SkyTrain district feature modern plumbing.
