To achieve this goal most spray head zones (sprinklers that do not rotate) need to run approximately 15 minutes and rotor zones (sprinklers that do rotate) need to run approximately 45 minutes. If you have much slope on your lawn areas you may need to run 2 cycles but with shorter run times on the zones.
Your lawn needs about 1 inch to 1 Â½ inch of water per week. It can be difficult to say accurately how long it will take you as that depends on your sprinkler. Most systems will take about an hour. One creative way to judge is to take an empty container about an inch deep (like a tuna fish can) and leave it in the grass.
