Deep dive for households

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

Water is cleaned at Petawawa Water Treatment Plant (OCWA-operated) before it enters city pipes. Upgraded 1993: coagulation, flocculation, sedimentation/clarification, filtration, chlorination. Rated 21,500 m³/d. Intake 760 mm, 490 m into river.

After treatment, water moves through pumps, storage, and underground mains to reach streets and buildings. Plant sits on southern Ottawa River shore surrounded by Garrison Petawawa; serves 11,000+ on municipal system.

One detail that makes Petawawa water feel local: The municipal plant is physically nestled against the army garrison that shares the town's name and riverfront. Lab grades for hardness, lead, and pH sit on the city water quality page; this overview is about the route the water travels.
