Where the water comes fromSurface water in Corvallis

Corvallis, City of serves 17,489 service connections. The system reports that figure to the EPA itself; this is the 2026 Q2 data.

What to do with thatGet your hardness figure

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