Whole House Reverse Osmosis in Lake Nona, FL
If you live in Lake Nona — Medical City, Laureate Park, Northlake, or any of the post-2010 master-planned villages — this page is for you. In short, a whole house reverse osmosis Lake Nona install solves OCU’s hard-water profile and the residual chlorine that affects taste at every fixture in the home, from the kitchen icemaker to the master shower. As a result, this page covers what’s in your tap water, why even brand-new Lake Nona homes benefit from an RO, and what we charge installed.
Moreover, Lake Nona sits in southeast Orange County, between the Orlando International Airport (north) and the Osceola County line (south). Specifically, ZIP 32827 covers Lake Nona Medical City, Laureate Park, Northlake, Eagle Creek, and the surrounding master-planned villages. Median household income runs about $132,000 per 2024 ACS data — solidly upper-middle, with one of the highest concentrations of post-2010 single-family homes and townhomes in Central Florida.
Furthermore, this page covers what’s actually in your Lake Nona water, why the OUC Southeast Reverse Osmosis Plant news doesn’t change anything for current Lake Nona homeowners, and our 4-step install process.
What’s actually in Lake Nona water?
Lake Nona is currently served by Orange County Utilities (OCU). The water comes from the Lower Floridan Aquifer through wells south and east of the city. Specifically, typical OCU system chemistry across the zones that serve Lake Nona looks like this:
- Hardness: 7 to 10 grains per gallon — moderately hard to hard. Anything above 7 gpg leaves visible scale on faucets and shortens appliance life.
- TDS: 280 to 360 ppm. A whole-house RO brings that under 20 ppm.
- Disinfection: OCU aerates and chlorinates the water (not chloramine). As a result, the carbon pre-filter on a whole-house RO removes residual chlorine before the membrane.
- pH: 7.6 to 8.0 — slightly alkaline.
- PFAS: OCU’s 2024 PFAS testing reports detection at multiple monitoring sites in Orange County. Whether your specific Lake Nona zone is above or below EPA’s 2024 MCL, a whole-house RO rejects PFAS at 95%+ efficiency.
- Lead: Non-detect at OCU’s distribution sample points. Importantly, Lake Nona’s post-2010 construction means no legacy lead service lines — but the water arriving at your tap still carries the same hardness and dissolved solids as any other Orange County zone.
About the OUC Southeast Reverse Osmosis Water Treatment Plant
You may have read about OUC’s $125-155M Southeast Reverse Osmosis Water Treatment Plant slated to begin operating in the Lake Nona area. Importantly, this is a municipal utility-scale RO plant — it treats raw water before distribution, not at your home. Furthermore, OUC’s plant treats brackish groundwater the city draws from deeper-aquifer wells; it does not change what flows out of your existing kitchen tap today, and it doesn’t replace the need for a whole-house alkaline RO inside your home.
In short: the OUC Southeast plant is excellent infrastructure news for the Lake Nona area in 5+ years. However, for a homeowner today, it changes nothing about what’s currently in your tap water or whether you’d benefit from a whole-house RO + softener combo.
Why a whole house reverse osmosis Lake Nona install pays off (even on new construction)
The most common pushback we hear from Lake Nona homeowners: “My home is brand new — why would I need this?”
A few specific Lake Nona reasons:
- Production builders don’t include water treatment. Specifically, premium Lake Nona builders (Toll Brothers, Pulte, Taylor Morrison, David Weekley, Tavistock) don’t include whole-house water treatment as standard. As a result, your brand-new Laureate Park or Northlake home gets the same 7-10 gpg hardness as any other Orange County home.
- Premium European appliances are common. Specifically, Sub-Zero, Wolf, Miele, Bosch, KitchenAid pro-grade appear in most Lake Nona kitchens. Manufacturer specs typically call for water under 7 gpg. Therefore, running them on OCU’s 7-10 gpg shortens heating elements and pump seals earlier than the spec.
- Glass shower enclosures and stone surfaces. Hard water etches glass and dulls travertine, marble, quartzite. Specifically, frameless shower enclosures and stone master baths are standard in Lake Nona master-planned communities.
- Coffee, tea, and ice taste. The chlorine residual is noticeable in cold water from the fridge dispenser. As a result, a whole-house RO removes the residual chlorine and the dissolved minerals.
The whole house reverse osmosis Lake Nona system we recommend
Almost every Lake Nona home is a good candidate for one of two options:
Option 1 — Whole-house alkaline reverse osmosis alone. $2,950. Specifically, if your home was built 2018 or later with high-efficiency appliances and you’re not seeing visible scale, this is usually the right call. The RO removes TDS, residual chlorine, PFAS, and trace contaminants.
Option 2 — Softener + whole-house RO combo. $4,150. However, if hardness scale is already a visible problem (white film on shower glass, spots on glassware, scale on faucets), add the softener. As a result, it removes calcium/magnesium before the RO, extending membrane life 3 to 5x.
Pricing — all-in, no surprises
| System | Price installed |
|---|---|
| Under-sink RO (kitchen only) | $495 – $895 |
| Whole-house alkaline RO | $2,950 |

FAQ — whole house reverse osmosis Lake Nona questions
Will the new OUC RO plant in Lake Nona change my home’s water?
The OUC Southeast Reverse Osmosis Water Treatment Plant treats raw water before distribution at the utility level. Importantly, it does not replace the need for a whole-house RO inside your home. Specifically, even after the OUC plant comes online, your tap water will still carry hardness and dissolved minerals — a whole-house alkaline RO is what removes those.
How hard is OCU water in Lake Nona?
Typical OCU system data shows 7 to 10 grains per gallon across the zones that serve Lake Nona. That’s moderately hard to hard — enough to leave visible scale on faucets, reduce appliance life, and build up in your water heater.
What disinfectant does OCU use?
Orange County Utilities aerates and chlorinates the water for disinfection (not chloramine). As a result, the carbon pre-filter stage on a whole-house RO removes residual chlorine before it reaches the membrane.
My Laureate Park home is brand new. Do I really need an RO?
Yes, in most cases. Specifically, Lake Nona production builders (Toll Brothers, Pulte, Taylor Morrison, Tavistock) don’t include whole-house water treatment as standard. As a result, your brand-new home gets the same 7-10 gpg hardness as any other Orange County home. Furthermore, premium appliances rated for water under 7 gpg will have shortened useful life.
Does the Lake Nona HOA require approval for an RO install?
Most Lake Nona HOAs (Laureate Park, Northlake, Eagle Creek) have architectural review boards. However, water treatment systems mount inside the garage or utility room — no exterior changes. As a result, ARB submission is typically not needed. Importantly, we’ll review your specific community’s covenants during the free consultation.
Can you install in a Lake Nona townhome?
Yes. Specifically, townhomes often don’t have garage utility space. As a result, we’ll do an in-home consultation to find the right mounting location — commonly under a utility sink, in a closet behind the master bathroom, or in a laundry room.
How often does the system need service?
Annually: pre-filter swap (10 minutes) and membrane flush. In addition, every 3 to 5 years: replace the RO membrane. We offer a $195/yr service plan that covers the annual.
