RE: Watering Restrictions Update
July 2nd, 2019


Thank you to all of our valued customers for helping to conserve water over these past few days as Upper Trinity works to repair their lines. Because of your cooperation, and the partnership between all the local water utilities and Upper Trinity, we are now able to lift the ban on all non-essential watering.

However, we will still have water restrictions in place until further notice. Outside watering will be restricted to one time per week as outlined below, and only between the hours of 7:00 pm – 10:00 am.

  • If your street address is an even number, your days to water will be Wednesdays between 7:00 pm and 10:00 am.
  • If your street address is an odd number, your days to water will be Fridays between the hours of 7:00 pm and 10:00 am.

Irrigation of flower beds, trees and foundations is permitted any day IF it’s by means of a hand-held hose, drip irrigation or soaker hose systems.Residents and businesses should be reminded to turn off their irrigation system after watering or adjust the controller to once per week! We appreciate your continued cooperation and working together as a community to help conserve water during this time.

Re: Mandatory Water Restrictions
June 28, 2019

Upper Trinity Regional Water District (UTRWD), one of the providers of water for Mustang SUD, has discovered a leak in its primary treated water transmission pipeline that serves a portion of its northeast Denton County water customers. The leak reduces Mustang SUD’s ability to fully serve the impacted customers and warrants mandatory temporary water restrictions. UTRWD is working diligently to assess the situation, repair the leak as quickly as possible and restore full service. During this time, the following water conservation measures are required:

Water Use Restrictions:

• Water customers are restricted from outdoor watering including irrigation systems until further notice.
• Limit water use to essential purposes only such as bathing, cooking, drinking, etc.
• Practice conservation and minimize or discontinue water use for non-essential purposes.

Thank you all, for being such valued customers and being mindful of water conservation. Mustang will inform customers when restrictions are removed. Please check our website and social media for updates. If you have any questions, please call our office at 940-440-9561.
