Where the water comes fromSurface water in Westminster

This is a surface water supply, which matters for hardness: the water has not spent years in an aquifer dissolving calcium out of stone. Expect a lower figure than a neighboring town on wells.

Westminster City of serves 33,619 service connections. The number is self-reported to the EPA and current to 2026 Q2.

What to do with thatGet your hardness figure

Westminster City of publishes an annual water quality report and the hardness figure is in it, so this costs you nothing but the time to look. It will be given in milligrams per liter. Softeners are sized in grains per gallon, and one grain is about 17 mg/L.

Put it through the sizing calculation and you will know what to accept and what to refuse. If your fixtures also stain orange, iron has to be settled first — oxidized iron clogs softener resin.
