How hard is Bowmanville water?
Durham doesn't publish a hardness figure, but Lake Ontario water measured elsewhere in the GTA runs 119 to 130 mg/L (about 7 to 7.6 grains per gallon), which is hard. Expect similar water here, and confirm it with a free in-home test.
At 7 grains per gallon and up you'll see white scale on taps and shower glass, spots on dishes, a crusty kettle, and water heaters that lose efficiency over time.
Why Bowmanville homeowners install softeners
Clarington is where Durham's lake towns meet moraine farmland. That mix is why one Clarington street needs a softener and the next concession road needs well treatment.
- Stops scale in water heaters, dishwashers and washing machines
- Spot-free glassware and shower doors
- Less soap and detergent
- Softer-feeling skin and hair
Which softener fits a Bowmanville home?
Bowmanville water is chlorinated (free chlorine of 0.32 to 3.70 mg/L in Bowmanville and 0.44 to 3.60 mg/L in Newcastle in 2025), so most homes are best served by the Enhanced Water Softener, which softens and removes chlorine in one tank. If chlorine doesn't bother you, SoftBlu is a straight, high-capacity softener.

Softens hard water and removes chlorine and chloramine in one system.

SoftBlu Water Softener
High-capacity softener that stops scale on fixtures, kettles and appliances.
See SoftBlu Water SoftenerWatching your sodium? Bowmanville's 2025 report shows sodium of 13.8 to 17.3 mg/L in Bowmanville and 15.5 to 40 mg/L in Newcastle. A salt-based softener adds a little more, so we can run yours on potassium chloride instead, and an RO tap at the kitchen sink removes most sodium from drinking water.
On a private well in Hampton, Enniskillen, Tyrone, Burketon, Kendal? Iron usually needs to come out before the softener. See well water treatment in Bowmanville.
