Water Softener Installation in Riverside, IL
Riverside is supplied by Riverside, 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.
The short version
The water reaching Riverside comes from Riverside, and its source is surface. Surface water has had far less contact with rock, so it is more often soft enough to leave alone. The annual water quality report carries the hardness figure, and that number settles the question before any equipment is sized.

Where the water comes fromSurface water in Riverside
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.
Riverside serves 3,034 service connections. The number is self-reported to the EPA and current to 2026 Q2.

What to do with thatGet your hardness figure
The annual water quality report from Riverside carries the hardness figure. Get it first, because everything downstream depends on it. It will be given in milligrams per liter. Softeners are sized in grains per gallon, and one grain is about 17 mg/L.
With the figure in hand, sizing is one multiplication — water per person, times hardness, times people. If your fixtures also stain orange, iron has to be settled first — oxidized iron clogs softener resin.
