A straightforward local referral service, built around one idea: give Highlands Ranch homeowners accurate information about their own water before recommending anything.
Highlands Ranch Water Systems is a local referral service. We connect Highlands Ranch homeowners with licensed, insured water treatment specialists in the Douglas County area for water softener, whole-house filtration, and reverse osmosis installation. We are not the installing contractor ourselves — every installation is carried out by a licensed local provider, and our role is matching homeowners with the right specialist and making sure that match starts with accurate information, not a generic sales pitch.
That starts with a free in-home water test. Highlands Ranch Water publishes a district-wide hardness range of 11–13 grains per gallon, and that number is the foundation for everything on this site — but it's a starting point, not a substitute for knowing what your specific home's water actually tests at. Every recommendation that follows a test is built around your household size, your fixtures, and your actual numbers.
Every hardness figure, source description, and treatment fact referenced on this site is drawn directly from Highlands Ranch Water's own published information — the utility's water hardness page, water quality FAQs, and annual water quality report. We link to those sources throughout the site rather than asking you to take our word for it. Where something is a general industry range rather than a district-specific fact — cost estimates, typical maintenance intervals — we say so plainly instead of presenting it as an official number.
A specialist tests your home's actual water for hardness, TDS, chlorine, and pH, and walks you through the results on the spot.
If treatment makes sense, you get a recommendation sized to your household and your actual numbers — not a one-size pitch.
A licensed, insured local specialist handles installation, typically within the same week.
Maintenance guidance — salt schedules, filter change intervals, membrane life — so the system keeps performing.
We serve homeowners throughout Highlands Ranch, including the Northridge, Southridge, Eastridge, and Westridge villages, newer communities like Backcountry, Firelight, and Canyon Ranch, and the broader ZIP codes 80126, 80129, and 80130, along with the surrounding Douglas County area.
Highlands Ranch's tap water meets or exceeds every EPA and CDPHE drinking water standard, as Highlands Ranch Water states directly. Nothing on this site is intended to suggest otherwise. The case for softening, filtration, or reverse osmosis in a Highlands Ranch home is about comfort, taste, and protecting the fixtures and appliances a nicer home tends to have more of — not about correcting an unsafe water supply. We'd rather be accurate about that distinction than oversell it.
Highlands Ranch Water Systems is an independent local referral service. We are not affiliated with, operated by, or endorsed by Highlands Ranch Water Metro District or the Highlands Ranch Community Association. Water quality data referenced throughout this site comes from Highlands Ranch Water's own public reporting, cited and linked wherever it's used.
No obligation, no pressure — just an accurate picture of your water before any recommendation.
