Mahogany Water Hardness & Quality Report (2026)

Mahogany's drinking water is managed by the City of Calgary, drawing from the Elbow River at the Glenmore Water Treatment Plant — Calgary's southeast water treatment facility. Water undergoes coagulation, sedimentation, filtration, UV disinfection, and chloramination, fully meeting the Guidelines for Canadian Drinking Water Quality (GCDWQ). Hardness in Mahogany is 194.5 mg/L (11.4 gpg) — classified as very hard by Health Canada, consistent with the outer southeast Calgary Glenmore plant distribution, similar to the adjacent Copperfield (193.5 mg/L).

Mahogany (a premier master-planned lakefront community in far southeast Calgary — one of Calgary's most award-winning new developments, centred on the 63-acre Mahogany Lake (a private community lake with lifeguarded beach and boathouse facilities), ringed with single-family homes and multi-family residences, and named North America's best-selling master-planned community multiple times by Avid Ratings) draws from the Elbow River Glenmore plant supply. The 194.5 mg/L is at the softer end of the Glenmore plant distribution range (213–249 mg/L from reference data), consistent with the far southeast distribution extremity similar to the adjacent Copperfield sub-zone.

At 194.5 mg/L, Mahogany homeowners face persistent scale challenges — monthly to bimonthly kettle and showerhead descaling is typical. Hot water tanks benefit from periodic inspection and flushing, and the private Mahogany Beach Club water features require active scale management. The City of Calgary provides water quality information at calgary.ca/water. Health Canada lead precautionary guidance applies, though Mahogany's entirely post-2010 construction features modern plumbing throughout.
