Supply and treatment
How Chilliwack 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
- Sardis-Vedder Aquifer
- Marble Hill Aquifer
Treatment plants
Chilliwack production wells (chlorination)
Ten production wells (eight Sardis-Vedder, two Marble Hill). City states source water quality meets guidelines without filtration; sodium hypochlorite is added at wells for distribution residual protection.
Distribution
Fourteen booster stations, seventeen reservoirs, and roughly 483 km of watermains. Groundwater Protection Plan enforced through zoning in the Groundwater Protection Area.
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.
