Recent Events

You may have seen some misinformation on social media and various news media outlets about our routine chlorine maintenance period which ended March 26. We want to assure consumers that our disinfection process is specifically developed and tested for our water source. The process used eliminates bacteria and viruses in the supply and distribution system. NTMWD uses common disinfectants: chlorine, chloramine (chlorine + ammonia) and ozone. Chlorine maintenance is a safe and scientifically proven preventive method to ensure that treated water remains safe as it moves throughout the pipes that distribute water to the local communities we serve.

The EPA, TCEQ, CDC and Water Research Foundation all indicate that the use of chloramines and free chlorine maintenance are safe, common, accepted and proven practices for maintaining water quality. Forty-five percent of the U.S. population is served by public water supplies using chloramine.

Our Water Treatment Process

NTMWD uses a proven, state-of-the art multi-step process to treat drinking water.
It’s not the least expensive system out there, but it is one that creates a disinfection process that eliminates bacteria, parasites and viruses through the combination of ozone, chlorine and chloramine (chlorine + ammonia).

About 45 percent of the U.S. population is served by public water supplies using chloramine, a proven and effective method of disinfection.

Because we use chloramine as a secondary disinfectant, it is a necessary and industry accepted practice to conduct routine chlorine maintenance. You can learn more about this process by clicking here.

NTMWD has been recognized for the superior performance of its treatment facilities in exceeding state and federal drinking water standards by the TCEQ’s Texas Optimization Program (TOP). More information on the TOP program can be found here.
