Clayburn Water Hardness & Quality Report (2026)

Clayburn's drinking water is managed by the City of Abbotsford, drawing from a local Fraser Valley watershed reservoir or groundwater source — Clayburn is a unique heritage community in east Abbotsford, the site of one of Canada's best-preserved early 20th-century industrial company towns, built by the Clayburn Company brick manufacturing operation in 1905 using the distinctive yellow-beige Sumas Mountain brick that built many of BC's historic buildings, a National Historic Site heritage community of original worker cottages and the Clayburn Village Store in the Matsqui Prairie east of Abbotsford. Water undergoes coagulation, sedimentation, filtration, UV disinfection, and chloramination, fully meeting the Guidelines for Canadian Drinking Water Quality (GCDWQ). Hardness measures 92 mg/L (5.4 gpg) — classified as moderately hard by Health Canada, consistent with the upper Fraser Valley local watershed character.

Clayburn's 92 mg/L reflects a local Abbotsford distribution sub-zone in the upper Fraser Valley, drawing from the watershed terrain east of the Metro Vancouver supply area. The Matsqui-Abbotsford area of the eastern Fraser Valley draws from local reservoir and groundwater sources in the Sumas Mountain and Vedder Mountain watershed terrain — Jurassic and Cretaceous volcanic and sedimentary rocks of the Cascades foothills, producing moderately hard water at the 90–100 mg/L range in the Abbotsford eastern distribution corridor, distinctly harder than the Metro Vancouver soft supply to the west.

At 92 mg/L, Clayburn homes experience light to moderate scale deposits — cleaning every two months is adequate. The City of Abbotsford provides water quality information at abbotsford.ca. Health Canada lead precautionary guidance applies to pre-1975 properties in the historic Clayburn Village heritage community.
