Does Your Tap Water Have A Chlorine Smell?
Chlorine is commonly used in municipal water systems to disinfect drinking water and eliminate harmful bacteria and viruses. In Detroit, water is treated by the Great Lakes Water Authority using a combination of filtration, ozone, and chlorine disinfection before being distributed throughout the system.
According to the most recent water quality data, Detroit maintains a total chlorine residual averaging around 0.84 ppm, which helps ensure water remains safe as it travels through miles of distribution pipes.
Chlorine can sometimes create a noticeable smell or taste, especially when water is first turned on or after sitting in plumbing.
Why Does Your Water Smell Like Chlorine?
A chlorine smell in your tap water is usually a result of the disinfectant doing its job. As water travels from treatment facilities through the distribution system, chlorine remains in the water to prevent microbial growth.
In Detroit, this can be more noticeable because:
- Water travels long distances from treatment plants to homes
- Chlorine residual levels are maintained for safety throughout the system
- Water may sit in household plumbing, allowing the smell to become more concentrated
Temperature, seasonal changes, and water usage patterns can also impact how noticeable the smell is at different times.
Chlorines vs. Chloramines: What’s The Difference?
Chlorine and chloramines are both disinfectants used to treat drinking water, but they behave differently.
Chlorine is a fast-acting disinfectant that effectively kills bacteria and viruses.
Chloramines are formed by combining chlorine with ammonia and are more stable over long distances in some water systems.
In Detroit, the system primarily uses chlorine-based disinfection, not chloramines, which means:
- Disinfection occurs quickly during treatment
- A measurable chlorine residual is maintained in the distribution system
- Some taste or odor may be more noticeable compared to chloramine systems
Both methods are approved and widely used across the country to ensure safe drinking water.
Why Is Chloramine Added To Water?
While Detroit primarily relies on chlorine, many cities use chloramine as a secondary disinfectant because it lasts longer in large or complex distribution systems.
Chloramine is added to:
- Maintain disinfection over longer distances
- Reduce the formation of certain disinfection byproducts
- Provide a more stable residual in systems where water travels far
Even in systems that use chloramine, some taste and odor concerns can still occur depending on individual sensitivity and plumbing conditions.
How To Remove Chloramine From Your Tap Water
If you notice a chlorine-like smell or taste in your water, you may want to consider filtration options designed to reduce chloramines.
This is a common concern in Detroit homes, especially for those sensitive to disinfectant taste or odor.
Effective solutions include:
- Reverse osmosis systems for drinking water
- Whole-house carbon filtration systems for broader treatment
These systems are designed to reduce chloramines and improve overall water quality throughout your home.

Does Detroit Use Chlorine or Chloramines?
Detroit’s drinking water system primarily uses chlorine as its disinfectant.
Water is sourced from the Detroit River and Lake Huron, treated at regional facilities operated by the Great Lakes Water Authority, and distributed across the system with a maintained chlorine residual for safety.
Current testing shows:
- Average chlorine residual: ~0.84 ppm
- Range: ~0.52 to 0.88 ppm
