Water Treatment in Tampa, Florida

Where does Tampa's tap water come from?

The Hillsborough River supplies most of it. The city's David L. Tippin Water Treatment Facility pulls from the river reservoir and can produce up to 120 million gallons a day at peak.

River water carries natural organic matter, so the plant runs it through several stages. Ferric sulfate pulls the organics out, ozone handles the primary disinfection, and biological filters polish the water. Chlorine goes in last, and the plant converts it to chloramine so it holds up across more than 2,200 miles of water mains.

One recent change: under a 2025 Florida law, the Tampa Water Department no longer adds fluoride.

What does hard water do inside a Tampa home?

It leaves calcium and magnesium behind wherever the water heats up or dries. You see it on glass first:

• White spots on dishes that come back after every rinse

• Crust on faucet aerators and shower heads

• Film on the shower door a few days after you clean it

• Soap and shampoo that need twice the amount to lather

You don't see the scale building inside the water heater, the dishwasher and the washing machine. It coats the heating surfaces, so the equipment runs longer for the same result and wears out sooner. Tankless water heaters push water through narrow heat exchangers, and their installation manuals list water quality limits for that reason.

Why does Tampa water smell like a pool for three weeks at a time?

The Tampa Water Department switches from chloramine to chlorine for about three weeks, several times a year, usually in winter and summer. The stronger disinfectant cleans out the distribution system. The water stays safe to drink, and you will smell the difference.

The city's advice for anyone bothered by it: run the tap for a few minutes, let a pitcher sit so the chlorine can escape, or use a carbon filter. A whole-house carbon system does the last one at every faucet and shower, so the switch weeks pass without you noticing.

The city tells dialysis centers and aquarium owners to keep using the chloramine removal they already run, because it removes chlorine too.

Is chloramine harder to filter than chlorine?

Yes. Utilities use chloramine because it lasts in the pipes, and that same stability makes it slower to remove.

A pitcher or refrigerator filter holds a small cartridge of carbon, and the water passes through it in seconds. For a whole house on Tampa water, we use catalytic carbon, which breaks chloramine down faster than standard carbon, in a tank sized for enough contact time.

Paired with a softener, that is our most-recommended Tampa setup: dual-media city water treatment.

Is there PFAS in Tampa's water?

Yes, at low levels. When the Tampa Water Department sampled the Tippin plant for the EPA's UCMR 5 study in 2023, PFOS results ranged from 4.0 to 6.9 parts per trillion, and PFOA from not detected to 4.6.

The EPA set a limit of 4.0 parts per trillion for PFOA and PFOS in 2024, with utilities due to comply by 2029. Those were single study samples, and compliance is judged on running annual averages. The city says it plans to build a suspended ion exchange treatment facility in the coming years.

If you want to reduce PFAS at your own tap before then, a reverse osmosis system is the most common option we install.

Do older Tampa homes need a closer look at their water?

Often, yes, because the city's water quality report describes water leaving the treatment plant. It can't describe what your service line and plumbing add before the water reaches your kitchen faucet.

The EPA says lead in drinking water comes mainly from service lines and household plumbing. Parts of Tampa were built long before Congress banned lead pipe and lead solder in 1986.

If your water tastes metallic, or you see staining your neighbors don't have, test at the tap. When you need documented results, we arrange certified lab testing.

What happens during a free water test?

We test at your kitchen sink, walk you through each reading, and explain what it means for your home. The visit takes about 45 to 60 minutes and costs nothing.

If the water only needs a softener, that is the quote. If it needs nothing, we tell you.
