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.
The correct way to determine this is to set out coffee cans or cups in the lawn and see how long it takes to fill the containers with 3/4 inch to 1 inch of water. Then set the sprinklers in that zone to run for that length of time. You can generally set the sprinkler times in the following way.
