Deep dive for households

Charlottetown drinking water starts as groundwater from wells. The named source on the utility record is Winter River watershed groundwater (municipal wellfields). That is the water that eventually reaches kitchen taps after treatment, not a separate bottled brand.

Water is cleaned at Charlottetown Water Utility disinfection / fluoridation facilities before it enters city pipes. No conventional surface-water filtration plant; groundwater from multiple wellfields is disinfected and fluoridated before distribution.

After treatment, water moves through pumps, storage, and underground mains to reach streets and buildings. Charlottetown Water and Sewer Utility extracts from about thirteen wells across municipal wellfields in the Winter River watershed (city materials variously describe three or four wellfields) and distributes citywide. PEI as a province is entirely dependent on groundwater for drinking water.

One detail that makes Charlottetown water feel local: Fluoridation continues because of a 1967 plebiscite. Utility emphasizes wellfield protection and land-use risk management north of the city where wells sit amid farmland. Lab grades for hardness, lead, and pH sit on the city water quality page; this overview is about the route the water travels.
