Water softeners in Harrisburg
Softener help for a fast-growing Lincoln County town served entirely by Lewis and Clark water.
Harrisburg, in Lincoln County just south of Sioux Falls, has grown quickly. The town had 958 residents in 2000, 4,089 in 2010 and 6,732 in 2020, and local officials estimated about 12,000 by early 2026. That means a lot of new homes, and a lot of first-time softener purchases.
Where Harrisburg's water comes from
The City of Harrisburg's 2025 water report says it buys 100 percent of its water from the Lewis and Clark Regional Water System. Lewis and Clark pumps from eleven wells in an aquifer recharged by the Missouri River near Vermillion, and the Minnesota Department of Health describes its lime softening process cutting hardness from about 300 ppm to about 160 ppm, followed by filters that remove iron and manganese.
What that means for your softener
Lewis and Clark water is softer than City of Sioux Falls water but still hard. The Sioux Falls 2025 report, which lists Lewis and Clark separately, shows 168 ppm total hardness and a 10-grain softener setting, along with 82 ppm sodium. Set your unit to a test at your own tap. Since Lewis and Clark already filters out iron and manganese, in-town homes usually need a softener sized for hardness alone; a test confirms it.
New construction
Many Harrisburg homes were built with a softener loop and a drain in the basement or utility room. If yours was, installation is mostly a matter of picking the right size, setting it correctly and making sure outdoor spigots bypass the softener.
