Harris County Municipal Utility District No. 504 began a temporary conversion in the disinfectant used in its water distribution system, from chloramine to free chlorine, on October 15, 2026. This service is expected to be completed on November 16, 2026. During this period, you may experience taste and odor changes associated with this type of temporary disinfectant conversion. These taste and odor changes are to be expected, however the water will continue to meet or exceed all state and federal drinking water standards and is safe to drink.
Why is this conversion performed?
Chloramine, formed by combining free chlorine and ammonia, provides long-lasting disinfection as water travels through the distribution system. Water utilities may temporarily switch to free chlorine to help control the buildup of microorganisms in pipes and maintain effective disinfection. This process can also help control nitrification, a biological process that can reduce disinfectant levels. A temporary conversion is a water-system maintenance practice and does not mean the water is unsafe to drink.
How does the process work?
During a typical temporary conversion, the water operator adjusts treatment so that free chlorine replaces chloramine as the distribution-system disinfectant. Crews flush water mains through hydrants or other flushing points to move treated water throughout the system and help clear loosened material. The operator monitors disinfectant levels and water quality during the conversion. Once the temporary maintenance period is complete, treatment is returned to chloramine. This work is performed on the public water system and customers don’t need to do anything on their side.
What might I notice in my water?
- Smell or taste: You may notice a stronger chlorine or swimming-pool-like smell or taste as the disinfectant changes. These changes can occur even when water meets drinking-water standards.
- Appearance: Flushing and changes in water chemistry may loosen mineral deposits or sediment, causing temporary discoloration. Minor discoloration does not mean the water is not suitable for drinking.
Is the water safe to use? Do I need to boil it?
Water treated with chlorine or chloramine that meets drinking-water standards is safe for drinking, cooking, bathing, and normal household use. A temporary disinfectant conversion alone does not require customers to take any action on their part.
