Reverse osmosis in Milton

Milton has two separate supplies. Halton pipes treated Lake Ontario water to the Steeles Avenue water tower, and the Milton well system supplies the rest. Under normal operation the two don't mix. In 2025 the lake-based system averaged 126 mg/L hardness, but the well-based system averaged 318 mg/L, which is very hard. The well side also has no added fluoride (0.10 mg/L) and higher sodium (45.6 mg/L).

A reverse osmosis system under the kitchen sink removes chlorine taste, most dissolved solids, sodium, lead and fluoride from drinking and cooking water. In very hard, high-mineral water like parts of Milton's supply, it's the biggest taste difference you can make.

• Better-tasting water, coffee, tea and ice
• Removes most dissolved solids, sodium and fluoride
• Its own faucet under the sink
• Usually cheaper than bottled water
