Smart Irrigation

Outdoor water use is estimated to account for roughly 30% of all residential water use, and landscape irrigation (lawn and garden watering) accounts for over 50% of that. Smart irrigation practices use less water and reduce water bills while promoting healthy lawns. Follow the smart watering tips below to help keep your grass green as you save some green.

Smart Lawn Watering Tips

  • Check irrigation systems for leaks and broken parts. Replace spray sprinklers with high-efficiency nozzles that produce droplets, not a mist that can evaporate or blow away.
  • When watering is needed, water early in the morning, between 4:00 a.m. and 8:00 a.m., to reduce evaporation.
  • Be aware that established lawns and landscapes need only about one inch of water each week.
  • Install a rain sensor and remember to adjust automatic sprinkler systems following rain events.
  • Switch to drip irrigation, which applies water directly to the roots of shrubs and trees.
  • Use a rain barrel or underground rainwater harvesting system for your landscape watering needs.
  • Reduce your lawn area and replace grass with native plants, groundcover or hardscape to reduce watering needs.
  • Set your mower blade to a higher setting to help shade roots and hold soil moisture longer.
  • Add mulch to help plants retain moisture.
  • Adjust sprinklers so they aren't watering the sidewalk or street.
