Temporary Changes in North Texas Municipal Water District (NTMWD) disinfectant processes.

Beginning on March 6, 2023, NTMWD will temporarily change their disinfectant process from Chloramine (Chlorine plus Ammonia) to straight Chlorine.  This change happens each spring for one month to help maintain the system throughout the year.

What does this mean for our customers?

Ammonia, which is normally added to extend the life of chlorine, will be temporarily suspended so the smell and taste of chorine may intensify.  Those with sensitive skin may experience redness or itching.

Is the water safe to drink?

Absolutely.  The amount of chlorine used to disinfect the water has not changed.

Why is this change important?

Chlorine is a stronger disinfectant than chloramine and is used for one month each spring to help maintain the system through the year.  This is a preventative measure to ensure the system is free of microorganisms and prepared for summer demands.

Why is the District flushing so much water?

Out with the old, in with the new.  Moving water through the system helps draw in the new, Chlorine treated water.  It’s also necessary to maintain state required chlorine residuals by Texas Commission of Environmental Quality (TCEQ).
