The only way to know how much water your lawn is getting when you turn on your sprinkler system is to measure it. You can do this by conducting an irrigation audit. First, make sure all sections of your lawn are getting coverage from your sprinkler system. If not, make adjustments.
Next, set out small containers throughout your lawn (tuna cans, water bottles or soda cans cut in half, etc.), let your irrigation run for 20 minutes, and measure how much water collects in each.
With this data, you can determine if you need to add or adjust sprinkler heads as well as how long you need to water to dispense one inch of water.
