A faint chlorine smell from the tap is common around Houston, and at certain times of year it can get stronger. Here is why.
Chloramine is the everyday disinfectant
The City of Houston’s 2025 water report lists chloramine, a combination of chlorine and ammonia, as the disinfectant in its main system, with an average of 2.8 ppm. That is under the 4 ppm limit, but some people still notice the taste or smell.
Temporary switches to free chlorine
Some area cities temporarily switch from chloramine to free chlorine as routine maintenance. Sugar Land, for example, ran its 2026 conversion from April 8 to May 6. During a switch, you may notice:
- A stronger chlorine smell
- Taste changes in drinking water and ice
- Slight discoloration or cloudiness while lines are flushed
Check with your own city or utility district for its schedule.
If taste and odor bother you
- Reverse osmosis: A reverse osmosis system under the sink treats the water you drink and cook with.
- Whole house filtration: Treats water at every faucet and shower. Chloramine can be harder to remove than chlorine, so choose a filter designed for it.
A water softener handles hardness, but it will not remove chlorine or chloramine.
