Deep dive for households

Stratford drinking water starts as groundwater from wells. The named source on the utility record is Local aquifers (Stratford wells). That is the water that eventually reaches kitchen taps after treatment, not a separate bottled brand.

Water is cleaned at Stratford municipal well supplies before it enters city pipes. City groundwater wells with disinfection feeding the urban distribution system; no Great Lakes intake.

After treatment, water moves through pumps, storage, and underground mains to reach streets and buildings. City-operated reservoirs, towers, and watermains across Stratford’s urban area.

One detail that makes Stratford water feel local: Stratford’s groundwater hardness is a common reason local households run softeners even though the municipal supply meets Ontario drinking-water standards. Lab grades for hardness, lead, and pH sit on the city water quality page; this overview is about the route the water travels.
