Watershed to tap
Supply and treatment
How Amos draws, treats, and distributes drinking water, from municipal and utility publications. Chemistry grades above come from separate parameter records; this section does not invent plant lab figures.
Source type
Groundwater
Research confidence: high
Source waters
- Esker Saint-Mathieu–Berry (municipal drains / wells)
Treatment plants
Amos esker supply / booster reservoir (historically untreated; preventive chlorination)
Exceptionally pure esker groundwater historically distributed without treatment. Preventive chlorination added after bacterial infiltration at booster reservoir; reservoir rehab underway aiming to reduce/stop chlorination.
Distribution
~98.8 km aqueduct; capture ~7.5 km SW of downtown via branched drains in the esker.
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.
