August 29 Update: The maintenance at our ozone facility is ongoing and is now expected to take several weeks. We're continuing to adjust to our water treatment operations to lessen the likelihood of noticeable changes in the taste of your water.
Our Environmental Services team tests our water for compounds that may impact taste and odor as part of our daily water quality testing. Sampling results from our latest tests indicate those compounds remain within normal levels.

Original Story
While some residents in the cities we serve may have noticed a slight change in the taste of their water recently, the water remains safe to drink and use. As part of our normal water treatment operations, NTMWD employs a process called ozonation. Ozonation helps mitigate the earthy taste that occurs naturally in the water from our lakes. Most of the water at our Wylie Water Treatment Plant is ozonated.
At our Wylie plant, we’ve had to perform some unplanned maintenance on one of our ozone systems after a recent overheating issue caused damage to the system. While this maintenance is occurring, some may notice a slight change in the taste of their water. So far, we’ve only received a limited number of reports of a change in taste from people in Wylie, Murphy, Richardson, Plano and Rowlett.
During this time, NTMWD is temporarily adjusting its water treatment operations to lessen the likelihood that people might notice the change in taste.
