Huntersville Water Treatment
Water Treatment for Huntersville, NC Homes
Huntersville is where Charlotte Water takes its water out of Lake Norman. Here is what the utility's 2025 report says about that water, what it means for a newer lake-area home, and what a free in-home test adds at your own tap.
Is Huntersville, NC water treated any differently than Charlotte's?
It is the same utility and the same Consumer Confidence Report, but Huntersville is closer to the source than most of the county. Charlotte Water (NC0160010) takes water from Lake Norman at an intake in Huntersville and treats part of it at the Lee S. Dukes plant across the street. Because the three plants feed one connected system, the 2025 numbers are system-wide: zero violations, chlorine as the disinfectant, and soft water at 32 ppm hardness. For most Huntersville homes, the practical question is chlorine taste, and a free in-home test shows what your own pipes add.
Huntersville's water and housing by the numbers
System-wide figures from Charlotte Water's 2025 Consumer Confidence Report, plus the Census Bureau's 2019 to 2023 estimates for the town. None of these are measurements from a single home.
| Lake Norman plant | Lee S. Dukes, in Huntersville | 25 MGD capacity, about 19 MGD average; intake at Blythe Landing |
|---|---|---|
| Lake Norman susceptibility | Higher | NC DEQ source water assessment cited in the report; Mountain Island Lake is Moderate |
| Violations (2025) | 0 | Zero drinking water violations reported |
| Chlorine residual | 1.04 ppm average | Range 0.47 to 1.60 ppm; maximum allowed 4.0 ppm |
| Total dissolved solids | 59 ppm | Range 52 to 66 ppm; secondary guideline 500 ppm |
| Typical home built | 2004 (median) | Census ACS 2019 to 2023; 76.5% detached single-family |
| Population change | +11.6% since 2019 | About 62,500 residents in 2023 (ACS 5-year) |
Huntersville is where the Lake Norman intake sits
Huntersville's old town water system (NC0160025) is listed as inactive by EPA, and Charlotte Water (system NC0160010) serves the town today. The Lake Norman intake that feeds Charlotte Water's Lee S. Dukes plant is in Huntersville, at Blythe Landing, and the plant itself is across the street. Dukes is permitted for 25 million gallons a day and averages about 19 million, according to Charlotte Water. The plant opened in the late 1990s because north Mecklenburg was growing and the county's water until then came from Mountain Island Lake. The distribution system is interconnected, so a public report cannot say which of the three plants fills a particular Huntersville tap. What the 2025 report does say is that the system had zero violations and disinfects with chlorine, not chloramine.
Huntersville, Cowans Ford Dam and a fast-growing lake town
Duke Power finished Cowans Ford Dam in Huntersville in 1963 and the Catawba River backed up into Lake Norman, which now covers more than 32,000 acres with 520 miles of shoreline. Huntersville grew with it. The Census Bureau's 2019 to 2023 estimates count about 62,500 residents, up 11.6 percent from 2019, in a town where the median home was built in 2004 and 76.5 percent of homes are detached single-family houses. Birkdale Village and the neighborhoods toward Ramsey Creek Park sit inside that newer housing stock, and the town's water service is Charlotte Water.

The local contaminants most likely to get attention in Huntersville
Chlorine residual: the taste most Huntersville homes notice
Charlotte Water keeps a chlorine residual in its pipes. The 2025 report shows it averaging 1.04 ppm, ranging from 0.47 to 1.60 ppm, against a 4.0 ppm federal maximum. It is well within the limit, and it is also the thing people smell in a shower or taste in a glass. Standard activated carbon handles chlorine well.
Low dissolved solids from a lake source
Total dissolved solids averaged 59 ppm in the 2025 report (range 52 to 66 ppm), far under the 500 ppm secondary guideline. Lake-sourced water arriving this clean is one reason scale is rarely the complaint in Huntersville, and why an in-home test matters for what your own plumbing adds.
What a free Huntersville in-home test measures
Charlotte Water's report describes the lake and the plants. The in-home test describes the last few feet of plumbing before your glass.
- Hardness (calcium and magnesium)
- pH
- Chlorine
- Iron
- Total dissolved solids (TDS)
- Nitrates
Results are explained the same day. The test does not measure PFAS or disinfection byproducts, which need a certified lab; this page uses Charlotte Water's own lab results for those.
How HydroSmart approaches Huntersville
Whole-home carbon for a chlorine-treated lake supply
Because Charlotte Water uses chlorine, a carbon-based whole-home system is the usual starting point for Huntersville: it takes the chlorine taste and smell out of every shower and tap at the point of entry.
See whole-home options →Reverse osmosis at the kitchen sink
In a newer home, an under-sink reverse-osmosis unit is a simple add-on for drinking and cooking water, without touching the rest of the plumbing.
See drinking-water systems →Sized after the in-home visit
The right equipment depends on how many people live in the house and how much water they use. HydroSmart sizes it after the in-home visit, not before it.

Huntersville water treatment FAQ
Is Huntersville, NC tap water safe to drink?
By federal standards, yes. Charlotte Water, which serves Huntersville, reported zero drinking water violations in its 2025 report, and its chlorine residual averaged 1.04 ppm against a 4.0 ppm maximum. Many homeowners still filter for chlorine taste.
Does Huntersville's water come from Lake Norman?
Part of Charlotte Water's supply does. The utility has an intake on Lake Norman that feeds the Lee S. Dukes plant in Huntersville, and two more plants draw from Mountain Island Lake. The pipes are interconnected, so the report cannot tell you which plant serves one address.
How is Lake Norman's water rated for contamination risk?
In the state's source water assessment, as cited in Charlotte Water's report, Lake Norman has a susceptibility rating of Higher and Mountain Island Lake a rating of Moderate. A susceptibility rating describes how exposed a source is to possible contamination. It is not a measurement of what is in your tap.
Do newer Huntersville homes still need water treatment?
It depends on what you want to change. The typical Huntersville home was built around 2004, so plumbing is relatively recent. That does not change the chlorine in the supply, and the free in-home test will show what is actually reaching your fixtures.
Does Huntersville have its own water system?
Not anymore. EPA lists the town's system (NC0160025) as inactive, and Charlotte Water (NC0160010) serves Huntersville. The water figures on this page are Charlotte Water's own.
