Quick summary
Dallas water questions are usually less about whether a single citywide number exists and more about which part of the regional system serves the address. Dallas Water Utilities publishes annual drinking-water reports, but hardness is not always easy to use as a simple consumer number from the public report alone.
For Dallas, use the public report for system-level context and a home test for address-specific questions like scale, taste, staining, or older plumbing.

Water hardness in Dallas
I could not safely verify a clear official Dallas hardness value from the accessible city report materials from the reviewed public sources. Treat hardness as address/provider-specific until confirmed by Dallas Water Utilities, a current report table, or a direct hardness test.
For scale, spots, or appliance buildup, treat published hardness as a planning clue and test at the home before sizing equipment.
Water quality reports
Use the Dallas report for system-level regulated contaminant results and source/treatment context. Do not use it as a faucet-level test for a specific home, apartment, building, service line, or fixture.
What Dallas homeowners should know
Dallas homeowners should separate citywide public report context from building-level questions. Public reports are useful for system-level quality, source-water context, and compliance. They do not test a specific building’s plumbing, fixtures, or service line.
Should you test your water?
A local test is most useful when the question is about the property itself: plumbing age, taste, odor, staining, sediment, private-well context, or treatment-equipment sizing.
For Dallas, testing is most useful when the provider is uncertain, the building is older, or you are making a treatment-equipment decision based on hardness, scale, or taste.
