Water Treatment in Casselberry, FL
Your Casselberry water is safe to drink, but the city runs a higher chlorine average than the rest of Seminole County. That is what gives your tap that swimming pool taste, and it also forms byproducts the city has to keep an eye on. On top of that, the water is hard, so you see white buildup on your faucets and glasses. We test your water right at your home, show you the real Casselberry numbers, and install the right system so your family gets cleaner, softer water from every tap.
What is in Casselberry tap water?
Casselberry tap water comes from the Floridan Aquifer, pumped through the city's three water plants. It meets EPA safety standards, but Casselberry runs a higher chlorine average than Seminole County as a whole, about 1.71 ppm in 2025. That chlorine is what gives the water a pool taste, and it forms byproducts like TTHM. The water is also hard. A whole-house softener plus reverse osmosis fixes the taste and the hardness.
The real numbers
What is actually in Casselberry tap water?
Here are the real facts about your water, straight from the City of Casselberry's own 2025 report. No scare tactics. You can check every number yourself.
Sources: Provider, source, chlorine, TTHM, HAA5, treatment process, fluoride, and lead service line status from the City of Casselberry 2025 Consumer Confidence Report (casselberry.org). Seminole County chlorine average from the Seminole County 2024 Annual Drinking Water Quality Report. Hardness context from USGS. Casselberry does not publish a hardness figure, so no city number is claimed here. This report does not include PFAS testing, so we make no claim about PFAS in Casselberry water either way.

What city water does in your home
If you live here, you already know. These are the exact words Central Florida homeowners use about their tap water.
“Smells like a swimming pool as soon as you turn on the tap.”
“Tastes like chlorine, I can't even drink it straight.”
“Everything has that white chalky film, glasses, shower doors, you name it.”
“Hair feels like straw and my skin is constantly itchy after a shower.”
“We were spending forty to fifty dollars a week on bottled water from Publix.”
None of this means your water is dangerous. It means it is chlorinated, hard, and heavier on both than most Casselberry homeowners realize. The good news: all of it is fixable.
How we fix Casselberry water
Two systems that work together
Casselberry water has two jobs to do. Soften the whole house, and clean up the water you actually drink. One system handles the hardness in every faucet and shower. The other handles the chlorine taste and the byproducts at your kitchen sink.
Whole-house water softener
Removes the hardness that dries your skin, stiffens your hair, and leaves white buildup on your faucets and glasses. Soft water in every shower and every faucet.
See water softenersReverse osmosis for drinking
Installs under your kitchen sink. Takes out the chlorine taste and the disinfection byproducts the city measures in Casselberry water, so you get clean water straight from the tap and stop buying bottles.

Casselberry water, explained
Casselberry water questions, answered
Who provides the water in Casselberry?
The City of Casselberry runs its own water through its Water Production Division, not Seminole County. It comes from three city plants: the North Plant, the South Plant, and Howell Park. All of it is pulled from deep wells in the Floridan Aquifer. We test your home directly, so you know exactly what is coming out of your tap.
Why is Casselberry's water more chlorinated than the rest of the county?
Casselberry averaged about 1.71 ppm of chlorine in 2025, higher than the Seminole County average of 1.29 ppm, with some readings as high as 2.90 ppm. Chlorine keeps the water safe, but at these levels it gives the water a pool taste and smell. A carbon and reverse osmosis system removes it from the water you drink.
What is TTHM, and should I worry about it in Casselberry water?
TTHM stands for trihalomethanes, byproducts that form when chlorine mixes with natural matter in the water. Casselberry measured 57.63 ppb, under the legal limit of 80. The city stays within the rules and even runs its South Plant water through carbon to keep it down. If you want it lower than that at your own tap, reverse osmosis and carbon filtration handle it.
Does Casselberry add fluoride to the water?
No. The fluoride in Casselberry water is natural, about 0.19 ppm, and the city did not add more to reach the old optimal level of 0.7 ppm. What is in your water is only what the Floridan Aquifer already carries.
Does Casselberry have lead pipes in the water system?
The City of Casselberry confirms it has no lead service lines feeding homes. That means the city mains are not a lead source. Any remaining lead risk would come from older plumbing inside a home, and reverse osmosis at the kitchen sink removes lead from your drinking water.
Is Casselberry tap water safe to drink?
Yes. It meets EPA safety standards. But safe does not mean it tastes good or feels good. The higher chlorine, the disinfection byproducts, and the hard water are all still there at your tap. That is a taste, comfort, and skin issue, and that is the part we fix.
