Where the water comes fromGround water in Sun City

A ground water system on this scale is usually pulling from a well field rather than a single bore, and the hardness of what it delivers reflects the aquifer underneath it rather than anything the treatment plant does.

EPCOR - Sun City serves 23,082 service connections. The number is self-reported to the EPA and current to 2026 Q2.

What to do with thatGet your hardness figure

EPCOR - Sun City reports its hardness every year. Reading that one line takes a minute and it is the step most households skip. Whatever it reads in milligrams per liter, divide by seventeen before comparing it with anything a softener is rated at.

Then run the arithmetic: it tells you the capacity you need rather than the capacity you are offered. If your fixtures also stain orange, iron has to be settled first — oxidized iron clogs softener resin.
