Denver Water’s summer watering rules are in effect May 1 to Oct. 1. There are no assigned watering days, but customers may water no more than three days per week. Lawn watering is not allowed between 10 a.m. and 6 p.m. to prevent losing water to evaporation.
Remember that each lawn is different, depending on the soil, amount of sunlight it receives and other landscaping factors. Use the watering times chart as a guideline, but experiment with your lawn. Try watering your lawn in cycles — five minutes on, five minutes off — to allow water to penetrate the soil and create a healthier lawn with less water. And try taking two minutes off the watering times for each zone. If that works and your lawn stays green, take off another two minutes.
