Water Softener Installation in Griffith, IN

Griffith is supplied by Griffith Water Department, which draws surface water. That one fact does more to predict whether a softener is worth it here than anything a salesperson will ask you on the phone.

Where the water comes fromSurface water in Griffith

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.

Griffith Water Department serves 5,749 service connections and is one of 2 community systems in the town. Figures are what the system filed with the EPA, refreshed for the second quarter of 2026.

EPA lists 2 community water systems here. They do not all draw from the same place, so hardness at one address in town can differ from hardness at another. Check which one bills you before you act on anyone else's figure.

What to do with thatGet your hardness figure

Griffith Water Department publishes an annual water quality report and the hardness figure is in it, so this costs you nothing but the time to look. Expect it in milligrams per liter; equipment is sized in grains per gallon. The conversion is roughly 17 to one.

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.

NearbyWhat other towns near Griffith draw

Source type is not uniform across a region. Four of the nearby towns we route are on ground water while Griffith is on surface, which is why a hardness figure borrowed from a neighbor is worth very little.
