Where the water comes fromSurface water in Sandy

A surface water system takes from a river, lake or reservoir. The contact with mineral-bearing rock is brief compared with an aquifer, which is why surface supplies generally test softer.

Sandy, City of serves 4,100 service connections. Figures are what the system filed with the EPA, refreshed for the second quarter of 2026.

What to do with thatGet your hardness figure

The figure you need is already published: Sandy, City of issues an annual water quality report, and hardness is one of the lines on it. 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.
