Highlands Ranch Water Treatment FAQ

Highlands Ranch Water publishes a typical range of 11 to 13 grains per gallon (188–222 mg/L), sourced primarily from the South Platte River. That places it firmly in the "hard" to "very hard" category on the standard water hardness scale used industry-wide. See our full water quality breakdown for the complete picture.

No. The district is explicit that it does not remove hardness during treatment, stating that hardness "is not a health hazard." Your water meets every EPA and CDPHE safety standard as delivered — softening is a decision made entirely at the home level, not something the utility handles for you.

Multiply household size by roughly 75–100 gallons per person per day, then by your water's hardness in grains per gallon. A family of four at 13 GPG lands around 4,000–5,200 grains of daily hardness load, which typically points toward a 32,000–40,000 grain softener. See our sizing guide for the full breakdown, or get an exact number with a free water test.

A softener removes calcium and magnesium hardness minerals through ion exchange. A whole-house filter removes sediment, chlorine, and taste/odor compounds — but it does not remove hardness. They solve different problems, and many Highlands Ranch homes run both. Compare softening and filtration side by side.

Most homes land between roughly $1,800 and $4,500 installed for a properly sized single-tank, metered softener — larger dual-tank systems or homes needing significant plumbing rework run higher. A free water test and in-home consultation gives you a number specific to your house rather than a rough estimate.

Yes, cumulatively. Scale buildup reduces water heater efficiency, contributes to earlier failure in dishwashers and washing machines, and is especially visible on frameless glass shower doors and matte or brushed-finish fixtures, which show mineral spotting more readily than polished chrome. Our protection guide covers this room by room.

Yes. Highlands Ranch Water states its supply meets or exceeds all applicable state and federal drinking water regulations. Everything on this site about softening, filtration, and reverse osmosis is about comfort, taste, and protecting your home — not correcting an unsafe supply.

No — it's optional. Reverse osmosis is a taste and quality upgrade, not a safety fix. It reduces dissolved solids and residual taste beyond what whole-house filtration covers, which is why many households choose it for drinking water, coffee, and ice specifically. Details on our reverse osmosis page.

Mostly keeping the brine tank filled with salt, checked roughly monthly. Resin beads typically last 10–15 years with consistent maintenance, and a demand-initiated (metered) system regenerates far less often — and uses less salt — than an older fixed-timer unit.

Most softener installations are entirely interior and don't require HOA or sub-association approval, since nothing about the home's exterior changes. Worth knowing: Highlands Ranch Water monitors chloride levels in the wastewater stream, partly influenced by softener regeneration discharge district-wide — a good reason to choose an efficient, demand-initiated system rather than an older fixed-timer unit that regenerates on a set schedule regardless of actual use.
