Annual Water System Maintenance Planned March 3 – 31, 2025

Rose Hill SUD purchases water from The North Texas Municipal Water District (NTMWD). NTMWD will temporarily change the disinfectant in its water treatment process from March 3 through 31, 2025. The annual, routine change is necessary to maintain the regional system and year-round water quality.
 
Disinfection is a critical part of the water treatment process that keeps drinking water free of harmful microorganisms, such as parasites and viruses. NTMWD’s water treatment plants use a two-step disinfection process where the water is treated, and then chloramine disinfectant (chlorine + ammonia) is added to maintain the water quality as it journeys through miles of pipes to homes and businesses. During the temporary change, NTMWD suspends adding ammonia and uses chlorine only to keep the water disinfected. This temporary change helps prepare the pipes for summer, when hotter temperatures can increase the potential for bacterial growth.

According to the U.S. Environmental Protection Agency, this temporary conversion is a common practice for many water providers using chloramines for disinfection. NTMWD follows the specified guidelines set forth by the Texas Commission on Environmental Quality (TCEQ) on how public water systems disinfect drinking water.

NTMWD has conducted the temporary change in water disinfectant for over fifteen years and continues to meet safe drinking water standards, earning recognition from the Texas Commission on Environmental Quality (TCEQ) as a Superior Public Water System.

During the change, the communities served by NTMWD may help move the chlorine-disinfected water through the system faster by flushing water from fire hydrants. The combination of converting to chlorine disinfectant and flushing the pipes helps maintain the system and safe water year-round.

NTMWD conducts hundreds of tests daily in a state-certified laboratory to ensure water safety. Monthly and annual water quality reports are posted online, including results of tests conducted during the annual system maintenance. Customers can view this information at www.NTMWD.com/water-testing/. The TCEQ also conducts routine sampling and testing in NTMWD and city distribution systems through an independent laboratory to confirm water quality compliance with state and federal standards.

NTMWD has posted resources at www.NTMWD.com/SafeWater, including fact sheets, frequently asked questions, infographics, videos, and guidelines for questions about water quality.
