Treatment plants
Powerhouse Springs Well Field
Seven groundwater wells supplying north and south distribution networks with disinfection. Stawamus River and Mashiter Creek retained as emergency surface backups only (not normal potable supply).
How it reaches your street
District-operated reservoirs and mains serve residential and industrial customers. Surface creek sources would need capital upgrades to resume as primary supply.

Lab water test for Squamish taps
Municipal reports cover the plant. A Tap Score kit tests the water at a Squamish tap for a broader contaminant panel.

Reading this page
Squamish's most recent drinking water sample (2026-07-22) reports hardness of 139 mg/L, classified as hard, and pH 7.7, drawn from a surface water source and treated at Squamish Water Treatment Plant. Lead measured 0.3 μg/L and fluoride 0.5 mg/L.
Free chlorine measured 0.8 mg/L in this sample. No E. coli was detected in this sample.
Squamish's hardness of 139 mg/L is below the British Columbia average of 139 mg/L across 31 tracked municipalities, with a provincial average pH of 7.5.
These readings summarize a single compliance snapshot, not a certification of the water reaching your tap. Test your own water periodically, especially on a private well, and consider a softener if hardness is classified hard or very hard.
How to use this page: read the headline metrics first, then where the water comes from (map and tap story), then the parameter table and source footer.
Health parameters meet Health Canada limits; turbidity above the 1 NTU typical target.
Health parameters meet Health Canada limits; turbidity exceeds the typical 1 NTU aesthetic target.
