The Chemistry Behind Your Municipal Tap: Charlotte Utility Facts
Source and disinfectant
Mountain Island Lake and Lake Norman on the Catawba River, with chlorine added at the plant and carried through thousands of miles of mains.
Byproducts
Charlotte Water reports THMs and HAA5 in its annual report.
The last mile
Older mains and household plumbing can add sediment after water leaves the plant.
Whole-House Carbon & Sediment vs. Pure Culinary RO for Charlotte Homes
Charlotte Water, the largest public water and wastewater utility in the Carolinas, treats lake water at three plants and says in its 2025 consumer confidence report that it adds chlorine to prevent bacterial growth. Its published mineral analysis shows total hardness of 32 ppm at the Franklin plant, so Charlotte water is relatively soft, and it reports monitoring for more than 70 PFAS compounds with low or undetectable levels.
Chlorine-rated carbon
Catalytic or activated carbon sized to Charlotte Water's chlorine residual.
Sediment stage
Captures main-break and flushing debris.
Culinary RO
RO for coffee, cooking and ice reduces many dissolved contaminants; your diagnostic shows what's in your water.
Appliance & Fixture Longevity: Protecting Charlotte's Older and Newer Homes
Older homes in established neighborhoods: original plumbing gains the most from a sediment stage at the main. High-rise and condo units: compact point-of-use RO protects coffee machines and fridge dispensers where whole-house space is limited. Tankless and steam appliances: chlorine is hard on seals, so carbon upstream extends their service life.
Elementa Care Plan & 2-Year Warranty for Charlotte Systems
2-Year Warranty + Elementa Care Plan
The 2-year manufacturer warranty begins the day you buy.
At 12 months, we perform your first annual maintenance free.
Then the Elementa Care Plan carries you forward: each annual service by certified Elementa NC technicians covers the next 12 months.
Coverage goes with the home: it transfers to a new owner who keeps the Care Plan.
Missed an annual visit? A more extensive restoration service reinstates coverage, priced at the time of service.
Had the system moved or reinstalled by a non-Elementa installer? The warranty pauses until an Elementa yearly check confirms it.
Charlotte Water FAQs
Does Charlotte use free chlorine or chloramine?
Charlotte Water's current consumer confidence report says it adds chlorine to prevent bacterial growth and lists a chlorine residual. We size a carbon stage to that and test the residual at your tap during the diagnostic.
Do you work in historic neighborhoods like Dilworth or Plaza Midwood?
Yes. Older homes often need a new shutoff or bypass before installation, and we spell that out in your blueprint before any work starts.
Will an RO system fit under a deep or farmhouse sink?
Usually. We measure the cabinet at the diagnostic and choose a layout that fits, or place the unit in an adjacent cabinet or basement.
