Water Softener Installation in Montpelier, IN
Montpelier is supplied by Montpelier Water Works, which draws ground 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.
The short version
The water reaching Montpelier comes from Montpelier Water Works, and its source is ground. Groundwater has been in contact with rock, which is where calcium and magnesium come from, so hardness is the likelier finding. The annual water quality report carries the hardness figure, and that number settles the question before any equipment is sized.

Where the water comes fromGround water in Montpelier
Ground water has spent time in contact with rock, and that contact is what puts calcium and magnesium into it. How much depends on what the rock is made of — limestone country produces the hardest water in the country.
Montpelier Water Works serves 700 service connections. That is drawn from the EPA's Safe Drinking Water Act file, 2026 Q2 refresh.

What to do with thatGet your hardness figure
Ask Montpelier Water Works for its water quality report, or find it online — hardness is on it, and it is the number the rest of this turns on. It will be given in milligrams per liter. Softeners are sized in grains per gallon, and one grain is about 17 mg/L.
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.
