Who we help

Homeowners in Sioux Falls, Brandon, Harrisburg, Tea, Hartford and the rural parts of Minnehaha and Lincoln counties who are dealing with hard water. That covers buyers of a first softener in a new house, owners of a basement unit that has quit, families whose city changed its water treatment, and acreage owners with iron or sulfur in their wells.

How hard is the water here?

It depends on who supplies it, and the Sioux Falls area has several suppliers. The City of Sioux Falls 2025 annual water report lists city water at 250 ppm total hardness with a recommended water softener setting of 15 grains per gallon. The same report lists water bought from the Lewis and Clark Regional Water System at 168 ppm and 10 grains. Harrisburg buys all of its water from Lewis and Clark. Brandon treats water from its own wells and recently added reverse osmosis softening that, according to a 2025 trade article, cut hardness from about 24 grains to about 12. Rural water systems and private wells have their own numbers.

Why that matters for your softener

A softener should be set to the water it's actually treating. Set too low, hard water slips through. Set too high, it regenerates more than needed and wastes salt and water. If you moved, if your water system changed its treatment, or if nobody has checked the settings since the unit went in, a quick test and reset is often the cheapest improvement you can make. Some homes also have outdoor lines plumbed through the softener, which wastes salt on the lawn.

Signs your water is hard or the softener has stopped

  • White crust on faucets and showerheads
  • Spots on glasses and dishes
  • Soap that doesn't lather
  • A noisy or slow water heater
  • Salt in the brine tank that never drops
  • Scale coming back after it had stopped

Wells and rural water

Outside the cities, many homes are on Minnehaha Community Water Corp, which produces water from local wells and buys about a third of its supply from Lewis and Clark, or on private wells. Private wells don't come with a water report. The U.S. EPA notes that owners are responsible for their well water's safety. Iron, manganese and a rotten-egg smell from hydrogen sulfide are common enough that a softener alone often isn't the answer. More on iron and sulfur filters.

Drinking water

Salt-based softeners add sodium to the water they treat, and Lewis and Clark water already carries 82 ppm sodium according to the Sioux Falls report. Many households add an under-sink reverse osmosis faucet for drinking and cooking. More on reverse osmosis.
