If your Pinellas County tap water smells or tastes more like chlorine than usual this fall, there may be a timely reason. Pinellas County Utilities is temporarily switching its disinfection process from chloramine to chlorine from September 21 through October 10, 2026. The county says customers may notice a slight difference in taste or smell during this routine maintenance period. For homeowners who simply prefer water with less noticeable chlorine taste or odor, properly selected carbon filtration or reverse osmosis may help.
If you’ve noticed a stronger chlorine smell in water coming from your Pinellas County tap, you aren’t necessarily imagining it. Pinellas County Utilities is conducting its fall 2026 Water System Maintenance Program from September 21 through October 10.
During this period, the utility temporarily changes its drinking-water disinfection process from chloramine to chlorine. According to Pinellas County, customers may temporarily notice a slight difference in their water’s taste or smell.
The change affects Pinellas County Utilities drinking-water customers as well as the Belleair, Clearwater, Safety Harbor, and Pinellas Park drinking-water systems.
The chlorine smell may be more noticeable when filling a glass, taking a shower, brewing coffee, or cooking. While that sensory change can be frustrating, it does not automatically mean something is wrong with the water.
Quick Facts About Pinellas County’s Fall Water Maintenance
Pinellas County Utilities temporarily switches from chloramine to chlorine during this period.
Customers may notice a slightly different chlorine taste or odor while the temporary treatment process is underway.
The program helps reduce the potential for coliform and other bacteria to form in the water distribution system.
For homeowners sensitive to chlorine taste or smell, properly selected filtration can make tap water more enjoyable.
Why Does My Tap Water Smell Like Chlorine?
Your tap water can smell like chlorine because chlorine is used to disinfect drinking water and protect it as it moves through the water distribution system.
In Pinellas County, the smell may be particularly noticeable during the current maintenance period because the utility has temporarily changed its secondary disinfection method.
Pinellas County normally uses chloramine, a disinfectant created by combining chlorine and ammonia. From September 21 through October 10, 2026, the utility is temporarily using chlorine instead.
This periodic process is part of Pinellas County’s routine water-system maintenance program and is designed to maintain water quality within the distribution system.
If your water suddenly seems more “pool-like” than usual during the current maintenance period, that does not necessarily indicate a problem inside your home. The temporary utility treatment change itself can affect the way tap water tastes and smells.
What Is the Difference Between Chlorine and Chloramine?
Chlorine and chloramine are both drinking-water disinfectants, but they behave differently in the water distribution system.
Chlorine is widely used because it is effective at killing potentially harmful microorganisms. Chloramine is formed when ammonia is added to chlorine and provides longer-lasting secondary disinfection as treated water moves through pipes.
Pinellas County normally uses chloramine as its secondary disinfectant. Periodically, the utility switches to free chlorine as part of its maintenance program.
According to the EPA, chloramines have been used by water utilities for decades and are commonly used to provide longer-lasting disinfection in water distribution systems.
Why Does Pinellas County Temporarily Switch to Chlorine?
Pinellas County temporarily switches from chloramine to chlorine to help maintain water quality and reduce the potential for bacterial growth in the water delivery system.
The county conducts the maintenance program once or twice a year depending on water-quality monitoring and sampling data.
For fall 2026, the temporary switch began September 21 and is scheduled to continue through October 10.
Pinellas County has stated that there are no indications of significant bacteriological contamination problems prompting this maintenance. Instead, the temporary treatment change is preventative and part of its regular water-quality program.
Is Chlorine in Tap Water Safe?
Chlorine is an established drinking-water disinfectant, and public water systems are required to comply with federal and state drinking-water standards.
The EPA regulates residual disinfectant levels in public drinking water. For chlorine and chloramine, the federal maximum residual disinfectant level is 4.0 milligrams per liter as chlorine.
Pinellas County says water will continue to meet federal and state standards during its fall maintenance program.
A noticeable smell alone also does not tell you the concentration of chlorine in the water. Human sensitivity to taste and odor varies considerably, so some homeowners may notice the temporary change more than others.
A chlorine smell during Pinellas County’s announced maintenance period may be expected. However, a sudden water-quality change accompanied by unusual discoloration, loss of pressure, a boil-water notice, or another unexpected condition should be checked against current utility notices rather than automatically attributed to routine chlorine maintenance.
Can a Water Filter Reduce Chlorine Taste and Odor?
Yes. Carbon-based water filtration is commonly used to reduce chlorine taste and odor in household water.
Activated carbon works through adsorption. As water passes through the media, chlorine and certain other substances interact with the carbon’s porous surface.
This can make a noticeable difference for homeowners who dislike chlorine taste or odor when:
- Drinking tap water
- Making coffee or tea
- Cooking
- Taking showers
- Washing fruits and vegetables
For homeowners who want treatment beyond a single drinking-water faucet, a whole-home filtration system can be designed to address water as it enters the home.
The appropriate filter depends on the disinfectant being used, water conditions, household flow requirements, and the homeowner’s treatment goals.
What About Chloramine Filtration?
Chloramine can require different filtration considerations than free chlorine because it is more chemically stable and designed to remain in the distribution system longer.
Standard activated carbon may reduce chloramine, but contact time and filter design become especially important. Catalytic carbon is commonly considered when chloramine reduction is a primary treatment goal.
This distinction matters in Pinellas County because the normal disinfectant and the disinfectant used during temporary maintenance are not the same.
A treatment system should therefore be selected with the home’s normal water conditions in mind, not only the temporary chlorine smell experienced during a maintenance period.
Can Reverse Osmosis Reduce Chlorine Taste?
Reverse osmosis systems can improve drinking-water taste, and residential RO systems commonly use carbon prefilters that reduce chlorine before water reaches the RO membrane.
RO is generally a point-of-use solution installed near a kitchen sink. Rather than treating every gallon entering the home, it provides filtered water primarily for drinking and cooking.
This can be useful for homeowners whose main goal is improving water used for:
- Drinking
- Cooking
- Coffee and tea
- Ice
- Pet water
Sayler’s reverse osmosis drinking water systems can provide targeted filtration when an RO system matches the household’s water conditions and goals.
Does a Water Softener Remove Chlorine?
A traditional water softener is not designed to be the primary treatment for chlorine taste and odor.
This is an important distinction because water softening and water filtration solve different problems.
A traditional softener primarily reduces calcium and magnesium, the minerals responsible for hard water. These minerals contribute to scale, water spots, soap scum, and mineral buildup inside water-using appliances.
Carbon filtration, on the other hand, can be used to address chlorine taste and odor.
A home can have both hard water and noticeable chlorine. In that situation, the homeowner may benefit from separate treatment technologies rather than expecting one system to solve both problems.
Understanding the difference between hardness, disinfectant taste and odor, sediment, iron, sulfur, and other common water problems helps homeowners avoid choosing equipment that does not match the issue.
When Should You Have Your Water Checked?
A professional water evaluation can be helpful when taste, odor, hardness, staining, sediment, or other water-quality concerns persist beyond a known temporary utility change.
During Pinellas County’s September 21 through October 10 maintenance period, a slight change in chlorine taste or smell may be expected.
But homeowners may want to investigate further when:
- An unusual taste or odor continues after maintenance ends
- Water suddenly changes color
- Scale repeatedly forms on fixtures
- Rust-colored staining appears
- Sediment is visible in the water
- Water pressure changes unexpectedly
- A private well develops a new taste or odor
Testing or evaluation can help separate a temporary municipal treatment change from a household plumbing issue or another water-quality concern.
If your municipal water suddenly changes, check current utility notices first. If the issue is not explained by a utility event or continues afterward, a professional water evaluation can help identify what to investigate next.
How Can You Improve Chlorine Taste and Odor at Home?
The right solution depends on whether you want to improve drinking water at one faucet or address chlorine taste and odor throughout the home.
A point-of-use system such as reverse osmosis may make sense when drinking and cooking water are the priority. Whole-home carbon filtration may be more appropriate when the goal is to treat water throughout the property.
Before choosing equipment, consider:
- Your normal municipal disinfectant
- Whether chlorine or chloramine is the concern
- Other water-quality problems in the home
- Household water usage
- Required flow rate
- Filter replacement requirements
- Whether you want point-of-use or whole-home treatment

For homeowners in Pinellas Park, Clearwater, Largo, Seminole, Dunedin, Palm Harbor, Safety Harbor, and surrounding Pinellas County communities, changes in municipal treatment can make water quality much more noticeable at certain times of year.
The current fall 2026 maintenance period is a good example. A temporary chlorine smell may be related to the utility’s planned switch from chloramine to chlorine rather than a problem with the home’s plumbing or water treatment equipment.
At the same time, every household has different preferences and water-quality concerns. Some homeowners simply dislike chlorine taste. Others may also be dealing with hardness, sediment, staining, or drinking-water concerns that require a different approach.
Sayler’s Suncoast Water helps Tampa Bay homeowners understand those differences and choose treatment based on the actual problem rather than relying on a one-size-fits-all system.
