Among in-ground clock-controlled systems, rotor spray heads, which rotate as they spray a jet of water, are more efficient than pop-up sprinklers which can spray up to 4 times more water than some lawns can absorb, leading to run-off and water waste.
Proper Irrigation and Lawn Maintenance
Which irrigation systems work best?
Among hose-end attachments, impact sprinklers, which spin slowly around or from side to side, apply water at a slower rate than oscillating sprinklers, which roll back and forth, and therefore lose less to evaporation.
- Use Denver Water's Run-time Scheduler to determine the exact watering duration for different irrigation zones.
- Mature fruit trees respond to deep watering; saturate the soil to a depth of 2-3 feet.
- Mulches will help conserve moisture. Use organic mulch, such as straw or bark chips, 6 inches thick; keep the mulch away from the tree trunk to lessen crown rot.
- Learn about different types of turf grass and their water needs
- Water deeply but not frequently. Do not overwater. Too much water can contribute to disease problems, runoff issues and leaching of nutrients. It's also a big waste of water.
- Use repeat cycle programming with pop-up heads to reduce runoff. Schedule each sprinkler to water for a portion of the time required, then "rest" while the water is soaking into the ground, then repeat.
- Have different watering zones that require different amounts of water.
- Consider installing a rain sensor which reduces water flow to the irrigation system during rainy weather.
- Consider installing a wind sensor that will shut down your irrigation system when winds get too high.
- Realign any heads that are spraying too high in the air, across pavement, or into the wrong zone.
- Consider non-spray irrigation for your flower and shrub beds. This includes soaker hoses, sub-surface piping, and drip irrigation.
- Add compost to your soil to increase its water retention.
