Water-treatment budget examples
Illustrative planning amounts help structure a written quote. These are not verified Highlands Ranch market rates or provider offers.
Hardness reduction
$1,800–$4,500Illustrative single-tank softener budget. Measured hardness, working capacity, flow and plumbing work must be specified.
Whole-home filtration
$2,000–$5,000Illustrative carbon/media system budget. These amounts do not imply softening or every contaminant reduction.
What must the final quote include?
Require exact equipment models, scope, labor, bypass, drain/electrical work, startup verification, permit requirements where applicable, warranty and exclusions. A second treatment stage, finished-wall access or substantial plumbing can change the total.
Compare recurring cost separately
Ask for salt, cartridges, media, membranes, service labor and replacement frequency. The calculator intentionally does not quote equipment: grain load is only one design input. Ask which consumables are proprietary and how parts will remain available.
Use the full quote checklist and compare the specific services.
Compare five-year ownership using your quotes
The planning examples above were reviewed October 18, 2026. They are illustrative allowances, with no local price survey or provider quote behind them. They are not evidence that your job will fall inside the range.
| Item | Softener | Carbon/media filter | Under-sink RO |
|---|---|---|---|
| Upfront scope | Tank, valve, bypass, drain and startup settings | Vessel, bypass, required drainage and commissioning | Unit, faucet, drain and any power or refrigerator line |
| Recurring items | Salt, regeneration water and model-specific service | Cartridges/media, backwash where used and service labor | Prefilters, membrane and sanitization; reject-water use |
| Quote evidence | Usable capacity at salt dose and peak flow | Target reduction claim, flow and media capacity | Exact certified claim, feed limits and replacement parts |
Worksheet: five-year total = installed quote + five years of your expected annual supplies/service + separately scheduled replacements. Example arithmetic only: $2,500 + (5 × $200) + $400 = $3,900. Taxes, financing and unexpected repairs need separate treatment; do not substitute these invented example inputs for a quote.
Request a replacement-cost schedule and use the full quote checklist.
