Water Conversion

Latest Update: 

City staff has been working on a comprehensive water main flushing program throughout the City in preparation for chloramine disinfectant conversion. For more information, please contact the Customer Service Department at 832-595-3400.


On January 31st, 2018, The City of Rosenberg  changed the water disinfectant from chlorine to chloramine. This change is intended to benefit our customers by reducing the levels of disinfection byproducts in the system, while still providing protection from waterborne disease.

While this is a positive change overall; persons dependent on dialysis machines will need to adjust the settings on their treatments to avoid a condition known as hemolytic anemia. This can occur if the disinfectant is not completely removed from the water that is used for the dialysate. Consequently, the pretreatment scheme used for the dialysis units must include some means, such as a charcoal filter, for removing the chloramine prior to this date. Medical facilities should also determine if additional precautions are required for other medical equipment.

In addition, chloraminated water may be toxic to fish. If you have a fish tank, please make sure that the chemicals or filters that you are using are designed for use in water that has been treated with chloramines. You may also need to change the type of filter that you use for fish tanks.
