North Texas residents may notice an abnormal taste and smell in their tap water during March due to routine maintenance by the region’s water district.

The North Texas Municipal Water District announced it would temporarily change its disinfection process by removing ammonia as part of its annual routine maintenance work. The water district is made up of 13 member cities, including Plano, McKinney, Frisco and Richardson.

According to the district, chlorine in water may be more noticeable throughout the month as maintenance is slated to continue through March 29. The water district has made details of the process available on its website.

“Protection of public health and keeping our water safe is a top priority,” said Zeke Campbell, the district's assistant director of water treatment and conveyance, in a statement. “This common maintenance practice is an essential step in our advanced year-round treatment and disinfection process and does not increase the amount of chlorine in the system. The water remains safe to drink and use every day, and we continue to meet or surpass safe drinking water standards.”

A district news release states customers can minimize taste, odor or skin sensitivities by placing a pitcher of water in the refrigerator overnight or adding a slice of citrus to the water. A crushed 1,000-milligram vitamin C tablet can also be added to bath water to neutralize the chlorine, according to the release.


The water district has conducted the temporary disinfectant change annually for more than a decade, the release states.
