Oklahomans know all about using water during the state's summer months, but many might not be monitoring exactly how much they're using.
Oklahoma State University horticulture professor John Haase says using measuring cups to catch water from sprinkler systems can serve as a cheap, easy way to record water usage.
Haase suggests placing nine cups in a square roughly three steps away from each other. Then -- if equipped with a 360-degree sprinkler -- place it in the middle of the cups and let it run for 20 minutes.

Then, Haase says to gather the cups and pour the water into a single measuring cup. The total can then be divided by nine for the average amount of output and multiplied by three to get the output per hour.
