Tillicum Water Hardness & Quality Report (2026)

Tillicum's drinking water is managed by the Capital Regional District (CRD), drawing from the Sooke Hills Wilderness Reservoir Area — Tillicum is a neighbourhood in the District of Saanich or City of Langford in the Victoria Western Communities, the Tillicum Road area in the inner western communities corridor between Victoria and Colwood-Langford, a residential community of suburban detached homes and strata properties along Tillicum Road near the Trans-Canada Highway (Highway 1) and the Tillicum Mall, adjacent to the Gorge Waterway recreational corridor and the Saanich-View Royal boundary. Water undergoes coagulation, sedimentation, filtration, UV disinfection, and chloramination, fully meeting the Guidelines for Canadian Drinking Water Quality (GCDWQ). Hardness measures 17.5 mg/L (1.0 gpg) — classified as soft by Health Canada, with TDS of only 29.5 mg/L — essentially near-source CRD supply, among the softest in the Capital Regional District.

Tillicum's 17.5 mg/L is at the near-source end of the CRD distribution — essentially identical to View Royal (14.5 mg/L from batch 33) and very close to the Sooke Hills reservoir source (19 mg/L from reference data), reflecting the proximity of the Tillicum western communities distribution to the CRD treatment facilities. The Sooke Hills Wilderness reservoir supply flows from the Leech River and Sooke River Jurassic-Cretaceous granodiorite terrain with essentially zero carbonate content, producing this near-pure soft water at the western end of the CRD distribution.

With 17.5 mg/L, Tillicum homes are completely scale-free — no descaling is needed. Hot water tanks and appliances have an outstanding operational lifespan. The CRD provides water quality information at crd.bc.ca. Health Canada lead and copper precautionary guidance applies, as the ultra-soft water increases corrosive potential for metallic plumbing, making flushing before use essential in pre-1975 properties.
