What the plant already does
Weston's 2025 Water Quality Report says treatment at the Sawgrass plant "includes a membrane softening process followed by disinfection." Membrane softening uses pressure to push water through membranes that hold back much of the calcium and magnesium responsible for scale. The result is that the water entering most Weston homes has already been softened at a large scale.
The report does not publish a hardness number, which is why the honest first step is measuring it at your own tap.
Bonaventure is a different plant question
Homes in the Bonaventure area are serviced by the City of Sunrise directly. Sunrise runs three service areas, and its reports describe different processes: Sawgrass uses membrane softening, while the Southwest plant uses lime softening. Sunrise's service area map shows which applies to an address. Either way, test before buying.
When a softener is the right call
- Your tap test shows hardness high enough to build scale.
- You are on a private well, where water skips plant treatment.
- You run a business: Living Water installs ion-exchange softening plants for restaurants, gyms, offices, schools, laundries and car washes, where water heaters, dishwashers, ice machines and washers run all day.
Ion exchange in plain words
A softener's resin beads trade calcium and magnesium for sodium or potassium. When the resin is loaded, it regenerates with brine and rinses to a drain. You need floor space, a drain and power near the main line. A softener does not remove chloramine, so if taste and smell are the concern, you need a filter instead. See softener vs. filter in Weston and salt-free conditioner vs. ion exchange.
Sodium and potassium
Weston's 2025 report already lists sodium at 38.8 parts per million in the water. Ion-exchange softening adds more sodium in proportion to the hardness removed. Potassium is an alternative regenerant. Since Weston's water is membrane-softened, the amount added in a typical city-water home would be small, but it is a fair question to ask with your test numbers in hand.
