Chilliwack is a rare larger BC city whose municipal potable supply is essentially unfiltered high-quality groundwater with only disinfection—not Fraser River surface treatment.
Treatment
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.
