Angus Water Hardness & Quality Report (2026)

The Angus Drinking Water System, managed by Essa Township, supplies about 12,000 residents in Angus, Simcoe County, Ontario, with groundwater. Its supply comes from three main facilities: Mill Street Pumphouse, McGeorge Pumphouse, and Brownley storage works. These sites draw water from local aquifers, which is then treated through filtration, chlorination, and pH adjustment before reaching homes. Notably, the system does not utilize any surface water from the Nottawasaga River or Lake Simcoe; it relies exclusively on groundwater.

Angus's water originates from groundwater aquifers situated within Simcoe County's bedrock. This geology is characterized by Paleozoic limestone and dolomite formations, part of the Ordovician-Silurian sequence common in central Ontario. As groundwater percolates through these carbonate rocks, it dissolves minerals like calcium and magnesium, leading to a characteristically hard water supply. The aquifer system here is confined, meaning it's protected by layers of glacial till, which limits the influence of softer surface water and preserves the mineral content leached from the bedrock over time.

Homeowners in Angus may notice scale buildup on appliances like water heaters, dishwashers, and faucets, which can reduce their efficiency and lifespan. You might also find that soap doesn't lather as easily, potentially leaving residue. To combat scale, regularly descale appliances with vinegar and consider flushing your hot water tank annually. Given the naturally hard water, installing a water softener is often recommended to protect your plumbing and improve cleaning. The system aims for a pH of 7.5-8.0 for corrosion control and meets all Ontario Drinking Water Standards.
