Deep dive for households
Chilliwack drinking water starts as groundwater from wells. The named sources on the utility record are Sardis-Vedder Aquifer, Marble Hill Aquifer. That is the water that eventually reaches kitchen taps after treatment, not a separate bottled brand.
Water is cleaned at Chilliwack production wells (chlorination) before it enters city pipes. 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.
After treatment, water moves through pumps, storage, and underground mains to reach streets and buildings. Fourteen booster stations, seventeen reservoirs, and roughly 483 km of watermains. Groundwater Protection Plan enforced through zoning in the Groundwater Protection Area.
One detail that makes Chilliwack water feel local: 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. Lab grades for hardness, lead, and pH sit on the city water quality page; this overview is about the route the water travels.
