What Makes Clairlea-Birchmount's Water Unique?

Local geology and source profile

Source: LakeTDS: 606.7 mg/LpH: 8.2

Clairlea-Birchmount (a residential neighbourhood in east Scarborough, Toronto, near Birchmount Road and Eglinton Avenue East โ€” a diverse community with a mix of post-war semi-detached homes, apartment buildings, and the Scarborough campus's western fringe) receives its drinking water from the City of Toronto, drawing from Lake Ontario via the R.C. Harris Water Treatment Plant on the Kingston Road lakeshore. Water is treated using ozonation, biofiltration, UV disinfection, and chloramination, meeting all Guidelines for Canadian Drinking Water Quality (GCDWQ) standards. Hardness in this distribution zone is 239 mg/L (14.0 gpg) โ€” classified as very hard by Health Canada, with TDS of 607 mg/L, characteristic of the east Scarborough distribution corridor.

Clairlea-Birchmount receives R.C. Harris plant Lake Ontario supply through the east Scarborough distribution network โ€” at the higher-hardness end of the Scarborough distribution spectrum, contrasting with the softer eastern sub-zones (Bendale 165 mg/L, Agincourt North 154.5 mg/L) and consistent with the typical central Toronto range. The 239 mg/L confirms that the western Scarborough corridor near Birchmount Road receives the standard very hard Toronto supply from the main R.C. Harris distribution.

At 239 mg/L, Clairlea-Birchmount residents face persistent scale build-up on kettle elements and showerheads โ€” descaling every one to two weeks is typical. Hot water tanks benefit from annual inspection and flushing. The City of Toronto provides zone-specific water quality information at toronto.ca/water; Clairlea-Birchmount's established Scarborough housing stock warrants lead service line review for properties built before 1955.

Geology & Source: Supplied by City of Toronto from Lake Ontario via the R.C. Harris Water Treatment Plant โ€” the Clairlea-Birchmount east Scarborough distribution zone carries very hard water at 239 mg/L (14.0 gpg).
