If you live in Sioux Falls, you’ve probably noticed the effects of hard water — spots on dishes, buildup on faucets, and soap that just doesn’t lather the way it should. Sioux Falls water averages approximately 15 grains per gallon (gpg), which places it firmly in the “very hard” category according to U.S. Geological Survey standards.
What Is Water Hardness?
Water hardness is determined by the concentration of dissolved minerals — primarily calcium and magnesium — in your water supply. The higher the mineral content, the harder the water. Here’s how water hardness is classified: Soft: 0–3.5 gpg Moderately Hard: 3.5–7 gpg Hard: 7–10.5 gpg Very Hard: Over 10.5 gpg At 15 gpg, Sioux Falls water is well into the very hard range.What Does Hard Water Do to Your Home?
Hard water might look clean, but it causes real problems over time:- Scale buildup in pipes — Mineral deposits restrict water flow and shorten the life of your plumbing
- Appliance damage — Water heaters, dishwashers, and washing machines lose efficiency and wear out faster
- Higher energy bills — Scale-coated heating elements work harder, driving up costs
- Spots and streaks — Calcium deposits leave white residue on dishes, glassware, and fixtures
- Dry skin and brittle hair — Hard water makes it harder to fully rinse soap and shampoo
- Soap and detergent waste — Hard water requires more product to get the same clean
