So here's the situation:
This customer hasn't turned on her sprinklers in weeks, and we get very little rain around here. This time of year, we're getting between 1/4" to 1/2" per week. Even with this little bit of rain, the lawn is still soaking wet literally all the time. It was even like this during the summer months when they'd only run the sprinklers for 5 minutes. It's so wet and muddy that my 21" Honda is leaving trench-like tracks across the yard when I've attempted to mow through it.

Ground conditions: There's no hills of any sort. It's completely flat/level ground. I'm not sure what the exact term is for its soil type. It's not sand or clay though. Not sure if that helps at all. Also, there doesn't appear to be a problem with run-off coming from any of the neighbors' yards.

The only thing I can think of is maybe there's a broken water line under the lawn somewhere, but the moisture problem isn't confined to one area of the lawn, so more than likely that isn't the case here. Anyhow, what's your take on this? Is there something I can do to relieve the lawn of some of this water? Fortunately it hasn't caused root rot in the turf, but I'm afraid it might since we're in cooler weather now.
Pardon me for jumpin in but i do leak detection.
To find a leak, verify the existence of the leak first.

Make a list of potential sources first.

1) House.
2) Yard.
3) Pool.
4) Pond.
5) Irrigation system.

1) Close all ISO valves, water stops for toilets, sinks, washing machines.
2) Close all ISO valves, close HBs and garden valves and ISO outbuildings.
3) Turn the autofill off and do a bucket test of the pool to see if the pool is leaking.
4) Turn autofill off, check pond for leaks.
5) Turn supply off at ISO valve or BFA, check for weeping valves, low head drainage and check the programming on the controller, there could be a buried runtime in the middle of the night.

Now that you know a bit about where to look and what to shut off, here's the next step.

Your supply will either a well or municipal.

If you are on a well the well will be running all the time or cycling a lot.

If on a meter take a pic of the dial with all the water on but not in use. Wait 5 mins and take another pic, compare the pics for dial movement.

Now the work begins.

1) If yov choose to close as you go, work to the meter or well.
2) If you choose to open as you go, work from the meter or well.
3) Have someone help you so you don't waste time running back and forth.
4) Pics are quicker than writing and much more accurate.
5) Gather all the info yov can before you do any digging.

The irrigation forum has a thread on this topic going right now.


Hope i helped some
