St. Catharines Water: Niagara Region Supply Facts
St. Catharines receives water drawn from Lake Ontario, treated at the DeCew Water Treatment Facility. The Niagara Peninsula's limestone geology results in consistently hard water, often above 12 GPG — one of the harder municipal supplies in Ontario. Chloramines are used as a disinfectant, which many residents notice as a taste issue.
Water Source
Lake Ontario via the Niagara Peninsula Water Supply System — Hardness: 10–14 GPG (Hard)
Common St. Catharines Water Issues
Hard Water (10–14 GPG): Severe scale buildup on faucets, showerheads, kettles, and appliances is the number one complaint in St. Catharines. Calcium and magnesium levels are high throughout the city.
Chloramine Taste & Odour: St. Catharines uses chloramines for disinfection, which are harder to remove than chlorine alone and leave a stronger chemical aftertaste in drinking water.
Seasonal Taste Changes: Lake Ontario intake conditions vary seasonally, occasionally causing taste and odour variations that a whole-home filter or under-sink RO system eliminates completely.
PureFlow's free in-home water test identifies your exact water issues and recommends the right solution — with transparent, fixed pricing and no pressure.
