What Makes South Slope's Water Unique?
Local geology and source profile
South Slope's drinking water is managed by the City of Burnaby, purchasing bulk supply from Metro Vancouver (GVWD) — sourced from the 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 South Slope distribution sub-zone is 70 mg/L (4.1 gpg) — classified as moderately hard by Health Canada, one of the harder Metro Vancouver outer distribution sub-zone readings in the south Burnaby corridor.
South Slope (a residential neighbourhood on the south flank of Burnaby's Central Park ridge, near the Edmonds SkyTrain station and the New Westminster-Burnaby boundary on Kingsway — a diverse mixed community of South Asian, Filipino, and established Burnaby families on the south slope below the Central Park forest, with access to the Edmonds Community Centre and the Burnaby-New Westminster commercial corridor) shows 70 mg/L — consistent with the pattern of harder Metro Vancouver outer distribution sub-zones observed at Kerrisdale (90.5 mg/L), Davie Village (81 mg/L), and Seafair (86 mg/L in Richmond). The south Burnaby corridor at the New Westminster boundary may receive supply through a pipeline routing that accumulates mineral content from the longer distribution distance and specific infrastructure of the Edmonds-area supply grid.
At 70 mg/L, South Slope homes experience light scale deposits — cleaning every two months is adequate. The City of Burnaby provides water quality information at burnaby.ca. Health Canada lead precautionary guidance applies to older pre-1975 residential properties in the established South Slope and Edmonds streets.
Geology & Source: Supplied by the City of Burnaby from Metro Vancouver (GVWD) reservoir water — the South Slope Burnaby distribution sub-zone records moderately hard supply at 70 mg/L (4.1 gpg), one of the harder Metro Vancouver outer distribution sub-zone readings in the Burnaby-New Westminster corridor.
