What Makes Highland West's Water Unique?
Local geology and source profile
Highland West's drinking water is managed by the Region of Waterloo, drawing from the Grand River via the Cambridge or Kitchener-area water treatment infrastructure — Highland West is a neighbourhood in the Cambridge or south Kitchener area of the Regional Municipality of Waterloo, in the residential communities along the Highland Road corridor in the Waterloo Region inner suburban belt, a community of mixed residential development in the Grand River valley country of southwestern Ontario. Water undergoes coagulation, sedimentation, filtration, UV disinfection, and chloramination, meeting all Guidelines for Canadian Drinking Water Quality (GCDWQ) requirements. Hardness measures 226 mg/L (13.2 gpg) — classified as very hard by Health Canada, consistent with the Waterloo Region Grand River supply corridor.
Highland West's 226 mg/L is consistent with the Waterloo Region Grand River supply — the same Silurian Guelph Formation dolostone and Salina Formation carbonate dissolution producing characteristically very hard water throughout the Cambridge–Kitchener–Waterloo supply network. At 226 mg/L, Highland West is consistent with the adjacent Columbia (221.5 mg/L), Christopher-Champlain (230.5 mg/L from reference data), and Greenway-Chaplin (229.5 mg/L from batch 28) sub-zones in the Waterloo Region distribution.
At 226 mg/L, Highland West residents face persistent scale challenges — monthly to bimonthly kettle and showerhead descaling is typical. The Region of Waterloo provides water quality information at regionofwaterloo.ca. Health Canada lead precautionary guidance applies to pre-1975 properties in the established Highland West neighbourhood.
Geology & Source: Supplied by the Region of Waterloo from the Grand River via the Cambridge or Kitchener water treatment system — the Highland West Waterloo Region distribution zone carries very hard Grand River supply at 226 mg/L (13.2 gpg).
