Deep dive for households

Hawkesbury drinking water starts as surface water (rivers, lakes, or reservoirs). The named source on the utility record is Ottawa River. That is the water that eventually reaches kitchen taps after treatment, not a separate bottled brand.

Water is cleaned at Hawkesbury Water Treatment Plant (670 Main Street West) before it enters city pipes. Conventional: coagulation/flocculation, Ultrapulsator and microsand ballasted clarifiers, high-rate sand/anthracite filters, clearwell, high-lift. Intake ~40 m offshore, ~4.5 m depth.

After treatment, water moves through pumps, storage, and underground mains to reach streets and buildings. Also pipelines to Vankleek Hill, L'Orignal, and Laurentian Park (Champlain). Standpipe ~5,400-5,450 m³; ~55 km watermains in Hawkesbury.

One detail that makes Hawkesbury water feel local: Town notes it takes about two days for Ottawa River water to reach the tap after treatment and distribution travel time. Lab grades for hardness, lead, and pH sit on the city water quality page; this overview is about the route the water travels.
