Brow of the Hill Water Hardness & Quality Report (2026)

Brow of the Hill's drinking water is managed by the City of New Westminster or City of Coquitlam, purchasing bulk supply from Metro Vancouver (GVWD) — sourced from the Coquitlam Lake watershed in the Coast Mountains. Water is treated at Metro Vancouver facilities using ozonation, biofiltration, UV disinfection, and chloramination, fully meeting the Guidelines for Canadian Drinking Water Quality (GCDWQ). Hardness in the Brow of the Hill distribution sub-zone is 32 mg/L (1.9 gpg) — classified as soft by Health Canada, consistent with the Metro Vancouver inner Tri-Cities soft supply.

Brow of the Hill (a residential neighbourhood on the south slopes of the New Westminster–Coquitlam boundary — the 'brow' of the hill overlooking New Westminster and the Fraser River, a community of detached homes on the hillside above the New Westminster Brow of the Hill area at the transition between the New Westminster plateau and the Coquitlam uplands, with dramatic views across the Fraser Valley) shows 32 mg/L — consistent with the Metro Vancouver Coquitlam Lake soft supply at the inner south slopes of the Port Coquitlam–New Westminster distribution zone, adjacent to Champlain Heights (30.5 mg/L from batch 32) and Eagle Ridge Port Moody (30.5 mg/L from batch 34) in the same Metro Vancouver inner ring. The Coquitlam Lake reservoir supply reaches this south-slope neighbourhood at near-source soft character.

With 32 mg/L, Brow of the Hill homes are essentially scale-free — occasional kettle cleaning every three months is adequate. Hot water tanks have an excellent operational lifespan. Health Canada lead precautionary guidance applies to pre-1975 properties in the established Brow of the Hill hillside neighbourhood.
