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.
- 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: a test of the backflow prevention device upon installation and annually thereafter.
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.
