What Makes New Westminster's Water Unique?
Local geology and source profile
New Westminster receives its drinking water through the City of New Westminster, drawing primarily from Metro Vancouver (GVWD) bulk supply sourced from the Capilano, Seymour, and Coquitlam mountain reservoirs, supplemented by local groundwater wells tapping the Fraser Valley Aquifer system beneath the Fraser River delta plain. Water is treated at the Seymour-Capilano Filtration Plant and local New Westminster facilities using ozonation, biofiltration, UV disinfection, and chloramination, meeting all Guidelines for Canadian Drinking Water Quality (GCDWQ) requirements. Hardness is 62 mg/L (3.6 gpg) — classified as moderately hard by Health Canada, substantially above Metro Vancouver's characteristic 4–6 mg/L due to the local aquifer blending.
New Westminster sits on a bluff above the Fraser River, where the Fraser Valley Quaternary Aquifer — a deep system of glaciofluvial sand and gravel deposits containing calcareous material from Cretaceous and Carboniferous rock clasts — contributes groundwater with moderate dissolved mineral load. As this local aquifer water blends with Metro Vancouver's soft mountain reservoir supply in New Westminster's distribution zone, the combined hardness rises to 62 mg/L — reflecting the aquifer's modest calcium contribution.
At 62 mg/L, New Westminster residents experience light scale deposits on tap aerators and kettle elements — occasional descaling every two to three months is sufficient. Hot water tanks operate reliably at this hardness without dedicated treatment. New Westminster's historic city centre — one of BC's oldest — includes many pre-1970 buildings where Health Canada precautionary guidance on lead is particularly relevant; the City of New Westminster provides water quality information and lead testing services at newwestcity.ca.
Geology & Source: Supplied by City of New Westminster from Metro Vancouver (GVWD) mountain reservoir water supplemented by local Fraser Valley aquifer groundwater — blending produces moderately soft water at 62 mg/L (3.6 gpg), elevated above the Metro Vancouver 4 mg/L baseline.
