Carey Water Hardness & Quality Report (2026)

Carey's drinking water is managed by the Capital Regional District (CRD), drawing from the Sooke Lake reservoir and the Goldstream watershed system on southern Vancouver Island — Carey is a residential area in the municipality of Saanich, in the western interior of the Saanich Peninsula near Carey Road and Tillicum Road. Water is treated at the Sooke Lake Water Treatment Plant using ozonation, biofiltration, UV disinfection, and chloramination, fully meeting the Guidelines for Canadian Drinking Water Quality (GCDWQ). Hardness in the Carey distribution zone is 87.5 mg/L (5.1 gpg) — classified as moderately hard by Health Canada, consistent with the upper range of the CRD Sooke Lake distribution system.

Carey's 87.5 mg/L is at the higher end of the CRD distribution range (Gordon Head 41 mg/L is the softer sub-zone), reflecting the specific distribution characteristics of the west Saanich supply corridor. The Sooke Lake watershed drains Wrangellia volcanic terrane and Vancouver Island Ranges metamorphic rocks, producing a naturally soft supply at the source; the 87.5 mg/L at Carey likely reflects the combined effect of distribution pipeline mineral accumulation and the specific western Saanich transmission routing from the Sooke Lake plant. The variation across CRD sub-zones (41–87.5 mg/L) is consistent with the range of sub-zone readings documented across the Greater Victoria distribution area.

At 87.5 mg/L, Carey residents experience light-to-moderate scale deposits — cleaning every two months is adequate. Hot water tanks have a good operational lifespan. The CRD provides water quality information at crd.bc.ca/water. Health Canada lead precautionary guidance applies to residents in older pre-1975 Saanich properties in the established Carey area residential neighbourhoods.
