Water Softeners in Miramar

Why Miramar is different from lime-softening cities

Until 2019, Miramar's East plant used lime softening, a chemical process. The city then converted it to nanofiltration, a pressure-driven membrane process. The West plant, built in the late 1990s, already used nanofiltration and reverse osmosis. Membranes like these are commonly used to soften water, so city water in Miramar tends to arrive with less hardness than raw groundwater would have.

The city's report does not publish a hardness figure, so the honest answer for your home is a test at the tap.

Where a softener earns its place

• Private wells. Groundwater that skips plant treatment can carry hardness and iron. Some properties in areas like Country Club Ranches have used wells. See well water treatment.
• Businesses with constant water use. Living Water installs ion-exchange softening plants for restaurants, gyms, laundries, car washes, offices, schools and hotels, where scale in water heaters, dishwashers, ice machines and washers adds up.
• A test that shows scale-forming hardness at your fixtures.

How an ion-exchange softener works

Resin beads hold calcium and magnesium and release sodium or potassium in their place. When the resin is full, the unit regenerates with brine from a salt tank and rinses to a drain. It needs a drain, power and floor space, usually in the garage. A softener does not filter chlorine; for taste and odor you need a filter. Compare in softener vs. filter in Miramar.

Salt-free conditioners

Salt-free conditioners change how minerals behave so they are less likely to form scale, but they do not remove hardness. Which one fits depends on what the test shows and what you want to protect. See salt-free conditioner vs. ion-exchange softener.

East of Palm Avenue or west of it

Miramar is one of the few South Florida cities where the plant serving you depends on which side of Palm Avenue you live on. Homes east of Palm Avenue to State Road 7 are normally on the East plant's nanofiltration water; homes to the west are on the West plant's nanofiltration and reverse osmosis water. Both are membrane processes, but blends and conditions in the pipes are not identical, which is another reason Jorge measures hardness at your tap instead of quoting a citywide number.
