Annual Chlorine Maintenance March 4 - April 1

Request email notification when page changes E-Notify

You might notice a slight change to the taste or smell of your tap water March 4 - April 1. This is due to a temporary change in disinfectant by Wylie’s water supplier, North Texas Municipal Water District. Though your water might taste or smell different, it is safe for drinking and bathing.

Visit NTMWD.com/safewater for more details.

What it is and why we need it:
Water suppliers must maintain a high level of quality throughout the water system to ensure drinking water is free of disease-causing microorganisms. This requires ongoing maintenance of the pipes that deliver water from NTMWD and tanks and towers that carry and store our drinking water.

Wylie’s water supplier, NTMWD, uses a mixture of chorine and ammonia to keep the distribution system clean and disinfected. For four weeks each year, NTMWD removes the added ammonia and uses chlorine only. This temporary change in disinfectant takes advantage of chlorine’s effectiveness at eliminating microorganisms and gives our water system a “deep cleaning.”

Our water is safe. Here’s how we know:
The Environmental Protection Agency creates federal water quality guidelines based on thorough, peer-reviewed research. Every treatment process used by NTMWD meets EPA safety criteria.

Thousands of water quality tests are performed annually by the City of Wylie, the NTMWD, and the Texas Commission on Environmental Quality. These tests verify that Wylie’s water meets all federal and state requirements for health and safety. Wylie is rated a “Superior Water System,” the highest standard. 

TCEQ QA: Facts about Drinking Water Disinfection and the Free Chlorine Conversion Process

Water may taste or smell different because:
For most of the year, NTMWD uses a combination of chlorine and ammonia to guard against bacteria in the water system. When ammonia is temporarily removed from the mixture, a chlorine taste and odor can become more prominent. Outdoor temperatures and overall water use also influence the reaction of chlorine to other materials in the water supply. This may cause smell and taste to fluctuate year to year.

NTMWD does not increase the amount of chlorine in the water during its four-week change in disinfectant; its taste and smell are more pronounced due to the absence of the ammonia.

Steps to reduce the taste or odor:
Not everyone notices a change in the water during this period. However, those who are sensitive to the changes can reduce chlorine taste and odor by running tap water a few minutes before using; refrigerating water in an open pitcher for several hours; or installing filters on faucets. While not required to meet safety standards, whole-home filtration systems can also help reduce taste and odors.

The City of Wylie is committed to water safety. More details about the annual maintenance can be found at www.ntmwd.com/safewater.
