Guelph is one of the few Ontario cities that relies entirely on groundwater wells — no surface water at all. That means consistent hardness at 22-34 GPG year-round, along with unique mineral characteristics that surface-water cities don't deal with. Our systems are designed specifically for Guelph's aquifer-fed water supply.

Unlike most Ontario cities that draw from rivers or lakes, Guelph sources all its drinking water from deep underground wells spread across the city. This means your water has been filtering through limestone and dolostone for thousands of years, picking up high concentrations of calcium, magnesium, and other dissolved minerals. The upside is consistency — Guelph's water hardness doesn't fluctuate with seasons. The downside is that it's hard all the time, and the deep aquifer minerals create challenges that surface water doesn't.
Guelph's groundwater minerals deposit steadily on every surface they touch — faucets, pipes, heating elements, and appliances — without the seasonal variation that gives other cities occasional relief.
While Guelph avoids the heavy chloramine treatment that surface-water cities need, groundwater carries its own distinct mineral taste that many residents notice in drinking water and beverages.
Constant hard water means constant scale on water heater elements, reducing efficiency year-round and increasing energy costs by up to 30%.
Hard groundwater minerals bind to fabric fibres, making clothes feel rough, colours look dull, and towels lose their absorbency.
Daily showers in 22-34 GPG water strip natural oils from your skin and hair, causing dryness, irritation, and a residue that moisturizers struggle to overcome.
Hard water forces you to use significantly more soap, shampoo, and detergent to get the same cleaning results — adding up to hundreds of extra dollars per year.
