Water IQ: Know Your Water

The North Texas Municipal Water District (NTMWD) was the first in Texas to implement the state’s recognized water-awareness campaign, “Water IQ: Know Your Water.” Water IQ is your source for easy, everyday water-saving tips, resources, and information.

Learn easy ways to manage your water bill. Also, test your water and turf savvy with the Water IQ Quiz and Turf IQ Quiz.

You may already be doing your part to conserve water — now it’s time to challenge yourself to do more to extend and conserve your water supply.

WaterIQ research indicates a direct correlation between knowing one’s water source and their willingness to implement water wise habits.*   Thanks in part to the NTMWD’s implementation of Water IQ over the last 10 years, 61 percent of consumers surveyed are able to name Lavon Lake as their primary source of water.**

Otis the Otter is the hero of the new water conservation campaign that the NTMWD debuted in 30 elementary schools in late 2014. The program was created with conservation funds awarded by the Texas Water Development Board, and is intended to serve as a statewide model.

History shows engaging kids in issues like recycling and protecting animals is very effective in elevating household discussion of cause-related issues. However, statewide research indicates only 28 percent of Texans know the natural source of their drinking water, and parents and children aren’t talking about water use at home. (2)

Water4Otter’s goal is to get Texas children to talk to their parents about water, and it’s already seeing success: Post-campaign surveys of 3,233 children show 78 percent of students went home and reminded their parents to save water.

The NTMWD’s water conservation program is being aggressively implemented to manage water use in order to meet short- and long-term water needs. The NTMWD will diligently protect, preserve, and extend the water supply to ensure that water is available to all its customers for use.


Water My Yard is a program of Texas A&M AgriLife Extension Service. It is under the direction of Dr. Guy Fipps and conducted in partnership with water districts, cities, and public utilities.

Current WMY partners include the following:

  1. Bryan/College Station
  2. City of Irving
  3. Lower Colorado River Authority
  4. North Texas Municipal Water District
  5. Park Cities Municipal Utility District
  6. Upper Trinity Regional Water District

A little about the science behind the recommendations:

The term evapotranspiration (ET) comes from the words evaporation and transpiration. This natural process can be used as a tool to provide irrigation and is used to measure the amount of water needed to grow different plants. Different types of plants will have different daily ET rates. This tool provides irrigation recommendations for warm season turf grasses such as St. Augustine, Bermuda, Zoysia, and Buffalo.

The precipitation rate is required in order to calculate watering run times. Please measure your sprinkler system's precipitation rate with catch cans, or inspect your system for the type, manufacturer and spacing.

Development of Water Conservation

Meeting state requirements, the NTMWD updates the NTMWD Water Conservation Plan, the NTMWD Member City, and Customers Model Water Conservation Plans every five years. The purpose of a water conservation plan is to ensure water use efficiency. The Water Conservation Plan strategies are implemented year round.
