Water Smart, Outside

Being Water Smart outdoors is all about following water conservation methods, choosing landscaping that performs beautifully in North Texas, and then applying only the water you need with an efficient irrigation system. The best way to be Water Smart outside is to know when to water.

Weekly Watering Advice

Sign up for weekly watering advice tailored to your location provided by our water district, Tarrant Regional Water District. You'll get a weekly alert that tells you just how much you should be watering due to recent rainfall and temperature!

Watering Schedule

Residents, businesses, and Homeowners Associations are required to follow this lawn watering schedule, and watering must be carried out between the hours of 6:00 p.m. and 10:00 a.m. on your designated days only. This watering schedule was adopted under the current Southlake 5-Year Water Conservation Plan.

Stage 1 Water Conservation Schedule


Southlake has adopted a permanent twice-per-week watering schedule (City's Code of Ordinances) to restrict the watering of landscapes and lawns using automatic irrigation systems between the hours of 6:00 p.m. and 10:00 a.m. every day, regardless of rainfall conditions. The purpose of this year-round restriction is to prevent the unnecessary loss of water to evaporation during the hottest hours of the day. Watering during these hours is permitted only if using a hand-held hose.

 The guidelines which the City of Southlake follows are in line with regional conservation efforts promoted by the Tarrant Regional Water District and the city's direct wholesale water supplier, the City of Fort Worth

Getting the Most Out of Your Irrigation System 

  • Start with an efficient irrigation system. Thoroughly check your system every 1 to 3 years for leaks, broken heads, etc. Try our W.I.S.E. Guys Program to get you started.
  • Each irrigation system is different. You will have to measure your irrigation system to determine how much to water when you water. 
  • Water with the weather. Your irrigation system is best if used as a supplement to natural rainfall. And, please remember to follow the twice-per-week schedule.
