Niagara Region Service Area
PureFlow now serves all of the Niagara Region — from St. Catharines to Fort Erie, Grimsby to Wainfleet. Niagara's limestone geology produces some of Ontario's hardest water, and many rural properties rely on private wells requiring comprehensive treatment.
St. Catharines
Niagara's largest city. DeCew-treated water with 10–14 GPG hardness and chloramine disinfection. Water softeners and RO systems are the top requests from St. Catharines homeowners.
View pageNiagara Falls
Some of Ontario's hardest municipal water at 11–15 GPG. Niagara Falls homeowners deal with rapid scale accumulation, iron staining, and chlorine taste issues year-round.
View pageGrimsby
Rapidly growing community on Lake Ontario's edge. New home buyers and long-term residents alike benefit from water softeners to protect their investment from Niagara Escarpment hard water.
