Water Softener Installation in Lafayette, CO

Where the water comes fromSurface water in Lafayette

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.

Lafayette City of serves 9,666 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

Start with the published figure. Lafayette City of reports hardness annually, and that number is what any honest quote gets built on. It will be given in milligrams per liter. Softeners are sized in grains per gallon, and one grain is about 17 mg/L.

From there, the sizing math takes a minute and tells you what capacity actually fits the household. If your fixtures also stain orange, iron has to be settled first — oxidized iron clogs softener resin.
