Where the water comes fromGround water in Lewes

Water drawn from below ground has had time to dissolve whatever the rock will give it. Calcium and magnesium are the two that matter here, because together they are what the word hardness means.

Lewes Board of Public Works serves 3,800 service connections and is one of 8 community systems in the town. The number is self-reported to the EPA and current to 2026 Q2.

What to do with thatGet your hardness figure

Start with the published figure. Lewes Board of Public Works reports hardness annually, and that number is what any honest quote gets built on. Reports use milligrams per liter, installers use grains per gallon, and mixing the two up is how people end up oversized.

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.
