Where our water comes from
Wrenford's drinking water is drawn from the Tamsin River and treated at the Tamsin River Water Treatment Plant. The plant removes sediment and bacteria, and adds the right amount of chlorine to keep your water safe as it travels through the pipes to your tap. The result is clear, odourless water that meets or exceeds all of Ontario's drinking water standards.
What is hard water?
Water hardness refers to the amount of dissolved minerals, mainly calcium and magnesium, in your tap water. Wrenford's water is naturally hard, usually measuring between 160 and 190 milligrams per litre. This is considered hard water and is common in Southwestern Ontario. The minerals wash down from the surrounding bedrock and soil before reaching the river.
How does hard water affect your home?
Hard water is perfectly safe to drink and does not cause health problems. However, the minerals can build up inside your pipes and appliances. You might notice:
- White crusty deposits (limescale) on faucets, showerheads, and dishes
- Soap scum that makes it harder to wash hands, clothes, or dishes
- Dry skin or frizzy hair after showering
- Higher energy bills, because scale builds up inside water heaters and makes them work harder
If you own a dishwasher or washing machine, hard water can shorten their lifespan. Using a water softener can help, but it adds sodium to the water. If you have a water softener, you may want to keep an unsoftened tap for cooking and drinking.
Managing scale and saving money
You do not need to soften your water to drink it. Here are simple ways to deal with hard water at home:
- Run hot water through a new faucet or showerhead for a minute before use to clear out loose scale.
- Clean showerheads and faucets with white vinegar or a lemon juice solution once a month.
- Use less hot water when washing clothes or dishes to reduce mineral buildup.
- Consider a descaling product for your water heater every few years.
If you are planning a renovation or buying a new home, ask the seller about the age of your water heater and whether a softener is installed. Replacing an old water heater can save a lot of energy if your water is hard.
Water quality reports
The City tests your water every day for bacteria and checks it weekly for minerals and other quality markers. We publish a full water quality report every year. You can read the report online or pick up a printed copy at Wrenford City Hall or any Wrenford Public Library branch.
