Temporary change in water disinfectant

Annual Water System Maintenance Planned March 2 – 30, 2026
Temporary change in water disinfectant is essential for safe drinking water

WYLIE, TX – Jan. 30, 2026 -- The North Texas Municipal Water District (NTMWD) will temporarily
change the disinfectant in its water treatment process from March 2 through 30, 2026. The annual,
routine change is necessary to maintain the regional system and year-round water quality.

“Safeguarding public health and ensuring safe water is our highest priority,” said Zeke Campbell,
NTMWD Director of Water Treatment and Conveyance. “Our advanced treatment processes are among the
most effective available, providing the communities we serve with safe and reliable drinking
water.”

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.

“This routine, temporary adjustment in water disinfectant is essential for maintaining optimal
conditions within our pipelines and ensuring year-round water quality,” said Campbell. “This
standard maintenance practice does not increase chlorine levels, and the water remains safe to
drink, consistently meeting or exceeding safe drinking water
andards.”
