Taste & Odor Issues

Water Sources


The Town of Little Elm purchases water from the North Texas Municipal Water District (NTMWD), which supplies us with water drawn from area lakes. The NTMWD utilizes Lavon Lake for its primary raw water source with additional raw water coming from Lake Texoma and Lake Chapman.

The annual chlorine maintenance began 03/13/2017 at 8:00 a.m. at the Wylie, Tawakoni, and Bonham WTPs and will continue for the next 28 days.

Residents may experience a stronger odor or taste of chlorine to the water supply; however, the water remains safe for use and consumption.

On the NTMWD website is a Chlorine Maintenance Fact Sheet at the following link: FACT SHEET: North Texas Municipal Water District

Additionally, the Town issued its own press release last week to prepare residents for the changes. CLICK HERE to download, print and read further details.


Algal Blooms


As with all surface water systems, algal blooms are possible during the summer and winter months. Algal blooms may cause taste and odor issues for some residents who are more sensitive to these changes. The taste and odor is a palatability issue only. The palatability change that results from a naturally occurring algal bloom does not alter the quality of the water provided to the cities and the communities served by the NTMWD. The water supply remains safe for use with no health risks created by these events.

Below are links to fact sheets about what algal blooms are and the steps the NTMWD is taking to minimize taste and odor issues caused by algal blooms:
  • Ozonation – Includes brief information about ozonation benefits and the NTMWD ozonation implementation plan at the Wylie Water Treatment Plants.
  • Summer Algal Blooms (specific) – A general fact sheet about summer algal blooms.
  • Taste and Odor (general) - Includes a general fact sheet about taste and odor, a summer bloom information page, and a winter bloom information page.
  • Winter Algal Blooms (specific) - A general fact sheet about winter algal blooms.
