Maywood Water Hardness & Quality Report (2026)

Maywood's drinking water is managed by the City of Burnaby, purchasing bulk supply from Metro Vancouver (GVWD) — sourced from the protected Capilano, Seymour, and Coquitlam mountain watersheds. 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 Maywood distribution sub-zone is 18.5 mg/L (1.1 gpg) — classified as soft by Health Canada, with a TDS of only 30.5 mg/L — among the lowest hardness and TDS readings recorded in the Metro Vancouver distribution system.

Maywood (a southeast Burnaby residential area near Byrne Road and the BCIT Burnaby campus corridor) records the 18.5 mg/L hardness — significantly softer than other Metro Vancouver south-side zones (Edmonds 47 mg/L, Riley Park 44.5 mg/L) — reflecting a specific distribution sub-zone characteristic. The very low TDS of 30.5 mg/L (approaching the source watershed's near-distilled water character of 4–6 mg/L) suggests that the Maywood sub-zone receives supply through a distribution branch with particularly short transmission distance and minimal pipeline mineral accumulation from the Seymour-Capilano treatment facility, retaining the fundamental softness of the Coast Mountain granodiorite mountain watershed supply.

With 18.5 mg/L of hardness, Maywood homes are almost completely mineral-free in their water — appliances and plumbing are fully scale-free. The very soft, very low TDS supply has virtually no scale risk whatsoever. The City of Burnaby provides water quality information at burnaby.ca. At this extreme softness, Health Canada lead and copper precautionary guidance is particularly relevant: very soft, low-TDS water is mildly corrosive and can leach metals from older plumbing; pre-1975 Burnaby properties should verify lead and copper service line status.
