What Makes Forest Heights's Water Unique?

Local geology and source profile

Source: LakeTDS: 765.8 mg/LpH: 8.6

Forest Heights receives its water from the Region of Waterloo water utility. This utility draws from groundwater sources, specifically wells tapping into regional aquifers. Treated at facilities such as the Ida Street Water Treatment Plant in Kitchener, this supply serves over 600,000 residents across Waterloo Region, including Kitchener, Waterloo, and Cambridge. The groundwater originates within the Grand River watershed, where recharge occurs through porous soils and fractured bedrock.

The region's groundwater is notably hard due to its geological underpinnings. The Ordovician-Silurian bedrock, characterized by limestone and dolomite formations like the Guelph Formation, is rich in dissolved carbonates. As water slowly percolates through these mineral-laden layers and fractured bedrock, it picks up a significant mineral content, leading to the characteristic hardness of this groundwater supply. This contrasts with the softer surface waters found elsewhere.

Homeowners will likely notice significant scale buildup in appliances and plumbing, which can reduce the efficiency of water heaters and dishwashers and increase energy consumption. Kettles and coffee makers tend to develop visible deposits quickly, and you might find that soap doesn't lather as easily. To combat these effects and prolong the life of your fixtures, regular descaling with vinegar, annual appliance maintenance, and the installation of a whole-house water softener are often recommended.
