PUBLIC NOTIFICATION

HARRIS COUNTY MUD 222 Public Water System ID# 1013054

Dear valued customer, on March 11, 2026, Harris County MUD 222 will be changing the disinfectant that we use from chlorine to chloramines. When the chloraminated water first flushes out the chlorine disinfectant water there may be a slight taste and odor, and possibly discoloration for a short period of time. This will not compromise the safety of the water.

The change to chloramines can cause problems to persons dependent on dialysis machines. A condition known as hemolytic anemia can occur if the disinfectant is not completely removed from the water that is issued 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.
