Water softeners in Brandon

Brandon's city water changed when its treatment plant expanded. Here's what that means for your softener.

Brandon sits about five miles east of Sioux Falls along the Big Sioux River and Split Rock Creek, and had 11,048 residents in 2020. It's home to the Big Sioux Recreation Area and a lot of newer housing. If you live in town, the biggest softener question right now is whether your settings still match the water coming out of the tap.

What changed at Brandon's water plant

Brandon's water is groundwater from city wells, averaging about 967,000 gallons a day in the city's 2024 drinking water report. The engineering firm on the plant expansion, AE2S, describes doubling capacity with a 2,000 gallon-per-minute addition that includes reverse osmosis softening on half of the water, aiming to cut hardness by 50 percent, plus aeration for iron removal and filtration for radium removal. A Water Conditioning and Purification article in 2025 reported that the RO system lowers hardness from about 24 grains to about 12, and quoted a local water treatment business owner saying most equipment in town would need to be recalibrated.

Why recalibration matters

A softener set for 24 grains on 12-grain water regenerates far more often than it needs to. That means more salt, more water down the drain and more wear. Twelve grains is still hard, so softeners still make sense in Brandon, but the setting should match a current test.

Outside city limits

Rural homes around Brandon may be on Minnehaha Community Water Corp, which blends its own well water with water bought from Lewis and Clark, or on a private well. Each has different water, so test before you set or size anything.

Common questions

Do I still need a softener in Brandon?

Probably, but at a lower setting. Reports on the plant expansion put treated water at about 12 grains, which is still hard.

Should I change my softener settings?

If your softener was set before the plant expansion, have the water tested and the unit reset to the current hardness.
