1 Based on this number (inches per hour), you can determine how long the sprinkler must run to provide your lawn with the amount of water it needs. 2  For example, in June, a typical Kentucky bluegrass lawn needs about 1.5 inches of water a week, which means you should water your lawn about a half inch three times a week. Pour all the water into one can, which equals the amount of water your sprinkler system delivers in one hour. 2  Based on this number (inches per hour), you can determine how long the sprinkler must run to provide your lawn with the amount of water it needs.
