Durham Region Water Context
Start with published local data, then confirm the property.
Municipal reporting is useful for an initial comparison. It cannot identify a problem caused by one fixture, a water heater, private plumbing, or a private well.
Hardness Reference
7.3 gpg
HardPlanning reference only. A supply zone or private source can produce a different result at the address.
Durham Region municipal supply
Hardness can affect comfort and equipment
Durham Region reports about 125 mg/L as calcium carbonate for the Pickering, Ajax, Whitby, Brooklin, and Oshawa municipal system—about 7.3 grains per gallon.
Scale and spotting may support a softener assessment. Taste, odour, or discolouration can point to a different issue and should not be diagnosed from hardness alone.

Water Doctor review:
3 checks before choosing equipment
- Check whether the symptom appears at every tap or only at one fixture.
- Compare hot and cold water; a hot-side issue may start at the water heater.
- Review the Durham Region source, then confirm property-specific conditions if the result will affect a purchase.

Water treatment in Oshawa
Does Water Doctor serve Oshawa?
Water Doctor reviews residential and business requests across Oshawa and the GTA. Submit the property address or postal code so the team can confirm coverage, timing, and the appropriate next step.
What does 7.3 gpg mean for my property?
7.3 gpg is a municipal planning reference. Scale and spotting may support a softener assessment, but taste, odour, discolouration, and hot-water-only symptoms can require a different diagnosis.
What information helps with a water-system recommendation?
Share the address, municipal or well-water source, the symptoms you notice, household or facility demand, and any photos of the available installation area. Those details help narrow the category and size without guessing.
Is the published hardness number the same at every Oshawa property?
No. 7.3 gpg is a planning reference for the municipal context, not an in-home lab result. Supply zones, private wells, premise plumbing, and water heaters can change what you experience at the tap.
When should I check the municipal report instead of booking an assessment?
Use the Durham Region source for system-wide reporting, advisories, and published averages. Request an assessment when you need to connect those facts to a specific address, symptom, flow requirement, or installation.
