Williams Lake aquifer (deep wells on Scout Island and North Lakeside)
Five deep wells (four Scout Island, one north shore), nine reservoirs (~20,000 m³), booster pumps between zones.
Taps draw from an aquifer beneath the lake valley—not from Williams Lake surface water—yet manganese still triggers a water-quality advisory for infants.
Treatment
Scout Island / Lakeside chlorination (pressure media filtration WTP funded for manganese)
Sodium hypochlorite disinfection at source today. Funded pressure-media filtration plant will add manganese removal and filtration.
Treatment on record: chlorination · filtration
