Why Your Water Tastes Like Chlorine in Tampa and Pinellas (Fall 2026)

Why does my water taste like chlorine in Tampa right now?

In fall 2026, your water tasted like chlorine in Tampa because the Tampa Water Department changed its disinfectant from chloramine to free chlorine on September 14, 2026. Pinellas County Utilities started the same change on September 21. Free chlorine is the disinfectant you smell at a swimming pool, and you notice it most in a hot shower.

If you are on Pinellas County water, the chlorine taste ran from September 21 to October 10, 2026, and it reached Clearwater, Pinellas Park, Safety Harbor and Belleair too, because those four cities buy county water.

The rest of the year, both utilities disinfect with chloramine, a mix of chlorine and a small amount of ammonia. The City of Tampa calls the temporary switch a routine measure practiced throughout the Tampa Bay region and by other public water systems around the country, in its September 2026 notice. Pinellas County runs its version as the Water System Maintenance Program, once or twice a year. Both 2026 windows are over, and the next dates come from each utility's own notice page. Both 2026 windows are over, and the next dates come from each utility's own notice page.

The two windows overlapped from September 21 to October 5. Tampa ran its previous switch from May 29 to June 19, which we covered in why your Tampa water suddenly smells like a pool.

Is my address part of the chlorine conversion?

Your address is part of the chlorine conversion if the City of Tampa or Pinellas County Utilities supplies your water. That includes New Tampa neighborhoods such as Tampa Palms and K-Bar Ranch, a few Hillsborough County neighborhoods on City of Tampa water, and the four Pinellas cities that buy county water. St. Petersburg is not part of either program.

Hillsborough County said the Tampa switch reached its customers in East Lake, Fairview Mobile Home Park, Hershel Heights, Pebble Creek and Seaboard, with chloramine back by October 6. Town 'N' Country is split between Tampa and county water, so check your water bill.

City of Tampa customers can read more on our Tampa water treatment page, and the New Tampa water guide explains why that part of the city tastes different through the year.

Why is St. Petersburg not part of the Pinellas conversion?

St. Petersburg runs its own water utility, so the Pinellas County program does not cover it. The City of St. Petersburg says it disinfects all of its drinking water with chloramines, and it has not announced a chlorine switch for fall 2026 on its drinking water page.

St. Petersburg has its own change underway, and it is easy to blame on the conversion. On September 4, 2026, the city warned of harder water, more deposits in filters and occasional rust-colored water while softening equipment at its Cosme Water Treatment Plant is offline for rehabilitation. The city began adding an orthophosphate and polyphosphate blend on September 8.

If your St. Petersburg water looks or tastes different this month, chlorine is not the cause. Our St. Petersburg water quality guide walks through the city's report, and St. Petersburg Water Resources takes questions at (727) 893-7261.

Why do Tampa and Pinellas switch to free chlorine on purpose?

Tampa and Pinellas switch to free chlorine for a few weeks to keep bacteria in check inside their water mains. Pinellas County says it designed the switch to reduce the potential for coliform and other bacteria forming in the water delivery system. The City of Tampa says chlorine helps maintain water quality throughout its mains and service lines.

Chloramine lasts longer in the pipes, which is why both utilities use it most of the year. Pinellas County also calls the switch an alternative to flushing millions of gallons of drinking water, and Tampa has been under extreme water shortage restrictions since April 3, 2026.

What will I notice during the chlorine conversion, week by week?

You will notice a chlorine or swimming-pool smell, strongest in hot water and the shower, and a sharper taste in drinking water, coffee, tea and ice. The timing depends on your utility, and the two 2026 windows only lined up between September 21 and October 5. Commuters across the bay tasted it at both ends for those two weeks.

Who needs to do something during the chlorine switch?

Most households only need to put up with the taste. Three groups should check their setup during a switch: home dialysis patients, anyone keeping fish, reptiles or a pond, and homes that already run a water filter.

If you dialyze at home, call your dialysis care provider. Pinellas County says dialysis machine users should not see an impact but should ask their provider about water testing and chlorine removal precautions. The City of Tampa has asked dialysis centers and medical facilities to take the same precautions they use for chloramine.

If you keep fish, reptiles or a pond, keep using your water conditioner. Pinellas County says the switch should not affect fish owners who already remove chloramine, and the City of Tampa asks aquatic pet owners to keep taking the same precautions. If your conditioner only lists chlorine on the label, check the dose with your pet supplier.

If your home already runs a water filter, the City of Tampa says to replace it with a new one. A refrigerator or faucet cartridge near the end of its life lets the chlorine taste straight through.

What removes the chlorine taste for good?

Carbon removes the chlorine taste for good. A whole-home dual-media system puts catalytic carbon in front of every tap, including the shower, and an under-sink reverse osmosis (RO) system handles the water you drink and cook with. A water softener on its own will not help, because softener resin does nothing for chlorine.

The City of Tampa's own tips include a carbon filter on kitchen or bathroom faucets and showerheads. Our most-recommended setup for city water homes is dual-media city water treatment, which pairs catalytic carbon with a water softener and covers every faucet and the shower at once.

The softener side handles Tampa Bay's hard water at the same time, since hardness and disinfectant taste are the two complaints we hear most from city water homes here. Homes that already run catalytic carbon get through a conversion without the pool smell.

For drinking water, a reverse osmosis system under the kitchen sink takes the chlorine taste out at the tap. RO systems run water through carbon first, partly because chlorine damages RO membranes, and the membrane then removes a wider range of dissolved solids than carbon can. We include an RO system free with a qualifying whole-home city water installation.

Bottom line: Most city water homes in Tampa Bay end up with both, because the two systems solve different problems.

How did one landlord handle three chlorine calls at once?

Thuy Pham manages three rentals on both sides of the bay. During one conversion season, her Tampa Heights tenant texted about a pool smell, then her Pinellas Park tenant sent the same message, and Thuy assumed the utilities explained both.

Then her St. Petersburg tenant said the water tasted off too. St. Petersburg was not converting, so we tested that tap. The water tested normal, and the real problem was a refrigerator filter two years past its change date.

Thuy replaced the filters in all three units and sent each tenant their utility's dates. She added whole-home catalytic carbon to the Tampa Heights duplex she plans to keep, and that building has not sent her a chlorine text since.

Is the water safe to drink during the chlorine conversion?

The water is safe to drink during the chlorine conversion. The City of Tampa says its water remains safe to drink and use throughout the switch. Pinellas County says its water continues to meet federal and state standards for safe drinking water and that boiling is not necessary. The change affects taste and smell, not safety.

Chlorine questions usually lead to disinfection byproducts, the TTHMs and HAA5s. Pinellas County says those health concerns relate to long-term exposure, not short-term maintenance, and the EPA sets both limits as running annual averages. Our city water quality guides cover them.

What can I do for free until the conversion ends?

You can cut most of the chlorine taste for free. The City of Tampa suggests filling a pitcher and letting it sit for several hours so the chlorine can dissipate. Free chlorine leaves standing water faster than chloramine does, so the pitcher trick works better during a conversion than the rest of the year.

The city also suggests running the tap for a few minutes first. Tampa is under water shortage restrictions, so catch that water for houseplants. Keep the pitcher in the fridge, since chilling dulls the smell, and swap any fridge or faucet filter that has been in service a while.
