Deep dive for households
Grand Falls-Windsor drinking water starts as surface water (rivers, lakes, or reservoirs). The named source on the utility record is Northern Arm Pond / Exploits regional surface system. That is the water that eventually reaches kitchen taps after treatment, not a separate bottled brand.
Water is cleaned at Exploits Regional Water Treatment Plant (New Bay Road) before it enters city pipes. Conventional plant (1995): hydrated lime pre-treatment, alum coagulation, plate settlers, multi-media filters, gas chlorination, lime post-pH. Design ~27.5 ML/d; orthophosphate corrosion control added ~2025.
After treatment, water moves through pumps, storage, and underground mains to reach streets and buildings. GFW operates plant for region serving GFW, Bishop's Falls, Botwood, Peterview, Northern Arm (~23,000 people).
One detail that makes Grand Falls-Windsor water feel local: One regional plant and dam on Northern Arm Pond feed five Exploits communities under a shared water-supply committee. Lab grades for hardness, lead, and pH sit on the city water quality page; this overview is about the route the water travels.
