Water Quality in Oakville, Ontario

Oakville’s municipal water comes from Lake Ontario and undergoes full treatment before reaching your tap. However, residents commonly experience issues related to water hardness, which typically ranges between 120–140 mg/L, hard enough to cause limescale buildup in pipes and appliances, spotting on dishes, and dryness in skin and hair. Trace chlorine and disinfection byproducts can also affect taste and odour.

While the water meets provincial safety standards, these issues are fully manageable with the right filtration system. WaterMart offers free professional water testing for Oakville residents, with tailored filtration recommendations costing you nothing.

What Filtered Water Can Do for You?

The right water filtration system is a profitable investment that repays you in terms of better health, softer skin, shinier hair, cleaner appliances, tastier food, and fresher water. Filtered water by WaterMart’s systems brings the following improvements in your life.

Health Benefits

Better Health & Taste

Filtered water is clear of lead, chlorine, bacteria, and several other harmful substances that carry health risks. It is healthier and safer to consume and has a refreshing and crisp taste that makes every sip a memorable experience.

Cost Efficiency

Healthier Skin & Hair

Hard minerals and chemicals like chlorine strip natural oils from your hair and skin, leaving your skin dry and itchy and your hair brittle and lifeless. Filtered water is gentle on your skin and hair, restoring their shine, softness, and life.

Increased Convenience

Longer-Lasting Appliances

Sediment and hard water minerals lead to scale buildup on your appliances, showers, floors, and sinks. Soft and filtered water protects your appliances, increases their lifespan, improves their efficiency, and lowers energy bills.

Environmental Benefits

Environmental Benefits

When you get an endless supply of clean water right at your tap, your dependency on single-use plastic bottles automatically reduces. As a result, you control your carbon footprint, keeping the environment clean and green.

Revitalize Your Life with Clean Water

Frequently Asked Questions

Check out common questions we get below.

Oakville’s tap water, sourced from Lake Ontario, is treated to meet provincial standards but can still contain chlorine and chloramines used in disinfection, trace amounts of lead (from older plumbing), sediment, and disinfection byproducts. The water is also moderately hard, meaning elevated levels of calcium and magnesium are present. A free WaterMart water test will give you a precise picture of what’s in your specific supply.

Most customers notice a significant improvement in taste and odour immediately after installation. For systems targeting hardness or dissolved solids, you’ll notice softer skin, improved water feel, and reduced scale on fixtures typically within the first week. Reverse osmosis systems may take a day or two to fully charge the storage tank before delivering peak-quality water.

Given Oakville’s moderately hard water and chlorine-treated municipal supply, most households benefit from a combination approach. A whole-home water softener addresses hardness and scale, while a reverse osmosis system at the kitchen tap provides premium-quality drinking water. WaterMart can assess your specific water chemistry and recommend the most effective combination for your property.

Yes. A water softening system is specifically designed to reduce hardness caused by calcium and magnesium minerals. With Oakville’s hardness levels averaging 120–140 mg/L, a softener can significantly reduce limescale buildup in pipes and appliances, extend the life of water-using equipment, and improve the feel of water on skin and hair. WaterMart offers several softening solutions suited to different household sizes and water usage levels.

In most cases, the impact on your water bill is minimal. Reverse osmosis systems do produce some reject water during filtration, but modern high-efficiency models have significantly reduced this. The long-term financial benefits, reduced bottled water purchases, extended appliance lifespans, and fewer plumbing repairs caused by scale typically outweigh any marginal increase in water consumption.

While some countertop or pitcher-style filters require no installation, most under-sink, whole-home, and reverse osmosis systems involve plumbing connections that are best handled by a certified professional. Improper installation can void warranties, cause leaks, or compromise system performance. WaterMart’s trained technicians handle all installations in Oakville, ensuring your system is set up correctly, efficiently, and backed by our full service warranty.
