The old rule of thumb is an inch of water a week either from the sky or from the garden hose/sprinkler system. In reality, it depends on the weather, the soil and the overall growing conditions. To know if you need to water, dig into the soil with your finger. If it is still damp, do not water yet. When you do water, apply it slowly so it soaks in rather than runs off. You need to water enough that it soaks down about six inches to the bottom of the lawn's root system. Then do not water again until it begins to dry out as judged by checking the soil. I hope this helps.
