Irrigation

Can I design, install, or repair my own irrigation system?

Yes, but you should contact the district's office for any questions regarding requirements for irrigation systems. The District does not have permits for irrigation systems being installed.  However, a copy of the layout for the irrigation system must be submitted for approval.  This is to verify that the home and the District will be safegaurded against the irrigaiton system.

  • Recommended: a licensed irrigator, installer (installers work under the direct supervision of an irrigator), or plumber connect you irrigation system to the public water supply.
  • Required: all irrigation system installed after 2009 on the same property as an OSSF system (septic/aerobic) are required to have a Reduced Pressure Principal Backflow Prevention Assembly (RP) installed. Required testing is: upon installation and annually thereafter. All tests must be submitted to the District's office.

What are the minimum state requirements my system must meet?

  • Sprinkler heads according to the manufacturer's recommendations.
  • Water pressure - your irrigation should not operate below or above the manufacturer's published specifications for the equipment being used.
  • Spray water only on landscaped areas - no water should spray over impervious surfaces.
  • Use a rain or moisture shutoff device or another technology (required in most Texas counties).
  • Install an isolation valve to turn off the water in case your irrigation system leaks.
  • Use an appropiate backflow prevention device (Reduced Pressure Backflow Prevention Assembly (RP)).

What are the steps I can take to conserve water?

  • Discuss your landscaping needs and plans with a licensed irrigator.
  • Discuss with the irrigator how long your irrigation system should run.
  • Remember newly established landscaping will require more water than an established area.
  • Ensure that your irrigation system does not spray water on concrete, wood, stone, brick, or other hard surfaces such as sidwalks, streets, driveways, fences, or walls.
  • Use drip irrigation systems in small areas.
  • Grassy areas typically use more water than landscaped beds, so you should plan seperate irrigation zones for those areas.
  • Make sure that there is correct water pressure for your irrigation system to produce large drops of water. Mist will evaporate.  Follow manufacturer's recommendations on pressures.  Understand how a rain or moisture sensor works to conserve water.

What should I do once my irrigation system is installed?

  • Water only after the top 2 inches of the soil has dried out.  You can use a soil probe to determine soil wetness.
  • Water 1 inch of water or more every 5 to 7 days to promote deep roots.  Grasses and shrubs will become more drought resistant.
  • Adjust the run time and frequency on the automatic controller monthly, based on changing rainfall and temperatures.  Trim overgrown shrubs or grass that may obstrucct the spray pattern.
  • Check sprinkler heads to remove dirt or debris that may clog nozzle heads.
