Water Softener Installation in Dover, MA

Dover is supplied by Aquarion Water Company (Dover), 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.

Where the water comes fromGround water in Dover

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.

Aquarion Water Company (Dover) serves 647 service connections and is one of 5 community systems in the town. That is the system's own return to the EPA, as of the second quarter of 2026.

What to do with thatGet your hardness figure

You do not need a test kit to start. Aquarion Water Company (Dover) publishes hardness in its annual water quality report, free to read. Expect it in milligrams per liter; equipment is sized in grains per gallon. The conversion is roughly 17 to one.

Work out your grains per day before anyone quotes you. Oversizing is the common and expensive mistake. If your fixtures also stain orange, iron has to be settled first — oxidized iron clogs softener resin.

NearbyWhat other towns near Dover draw

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