Highlands Ranch's water, straight from the source
The utility describes a combined surface-water and groundwater supply, averaging 85% surface water annually. Its 2026 report covers 2025 monitoring, with older sampling where noted. Hardness is an equipment and household preference question; public-system results do not replace a tap measurement. Read the official supply explanation and our filter-versus-softener comparison.

Explore the grain load before choosing a softener
Use measured hardness and indoor water use to explore daily and seven-day grain load. The default 12 GPG is the utility range midpoint, not a tap test; no equipment size or price is selected.
60 is an illustrative starting assumption, not measured local household use. Use indoor meter data when available. Exclude irrigation.
Daily load = people × indoor gallons/person/day × hardness. Seven-day load = daily load × 7. These loads are not a rated softener capacity, price, salt setting or flow specification. See the water softener page. Confirm actual hardness, peak flow and usable capacity at the chosen salt dose before equipment selection.
