Dear Harris County MUD #489 Resident,
The Harris County MUD 418 public water system, (PWS) ID 1013329, will convert the disinfectant used in the distribution system from free chlorine to chloramines in specific sections of Harris County MUD 489. The conversion will take place on Friday, November 11, 2022, and is meant to provide relief on the demand at Water Plant #2, as Bridgeland continues to expand on both sides of Highway 99. During this period, you may experience taste and odor changes associated with this type of disinfectant conversion.
Public water systems are required to properly disinfect their water and maintain an adequate disinfectant residual in the distribution system. Chloramines are widely used as a disinfectant because it persists for long periods, while also limiting the formation of disinfection by-product contaminants.
Please be advised, the change to chloramines can cause problems to persons dependent on dialysis machines. A condition known ad hemolytic anemia 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 the fish tank.
The sections that will be affected include:
- Mission Tejas
- Goose Island
