Top Ways to Reduce Water Use Now


  • Adjust sprinklers to water only the landscape - not pavement.
  • Adjust lawn mower height to 3 inches - longer lawns use less water.
  • Water in the early morning when winds and temperatures are low to reduce evaporation and over spray.
  • Check irrigation systems regularly for leaks and broken heads - then repair.
  • Convert a portion of your lawn to low-water-use Mediterranean plants on drip irrigation. 
  • Use 2 to 3 inches of mulch around plants to reduce evaporation loss from the soil.
  • Limiting outdoor watering to no more than 3 days per week and avoid watering between 9 a.m. and 7 p.m.
