Look at her previous usage. She should be fairly stable once the sprinkler system was turned off at the end of last Summer.
What was her average usage, and what is it now? That should also indicate WHEN the break happened, and/or got worse. Once you know the current excess consumption, compare it to the baseline average, and voila, that's how much you'r leaking. Divide by 30 and find out approx how much is leaking a day.
That's all interesting, but doesn't really solve your problem. To solve the problem, you have to find the pipe, dig it up, look for clues about which way the water is flowing, then proceed in that direction.
Unless the lawn slopes DOWN to the house, I doubt the leak is close to the meter, instead, probably closer to the house side somewhat near the demarcation line where there's dry ground.
