Water-use clue
A higher water bill and wet ground outdoors
A higher bill and a wet patch may be connected, but neither proves the other. Start with the dates and your utility's meter guidance, then give a professional both pieces of evidence.
Evidence sequence
Check the use pattern before the ground
Compare like with like
Compare the current bill with the same period last year when possible. Check the start and end dates and whether the utility estimated a reading. Note occupancy changes, seasonal watering, pool filling, or other known outdoor use. A higher bill alone is not a location clue.
Observe the meter only if it is safe and accessible
EPA WaterSense suggests reading the meter during a period when no water is being used, then checking again two hours later. Do not interrupt essential water use or open a locked or unsafe meter enclosure; if a true no-use period is not practical, ask the utility for its recommended check. A changed reading can indicate a leak or unrecognized use somewhere on the metered system.
Pair readings with the outdoor pattern
Note whether the wet area changes after irrigation. Some properties meter outdoor water separately, so confirm what your reading covers with the utility. A stable reading during one check cannot rule out an intermittent leak, use outside that meter, or a bill-period change.

Prepare one clear summary
What to have ready for the utility
Keep the bill period and meter observation together so the dates can be compared. Record whether all expected water use was paused during the meter check, whether any irrigation system has a separate meter, and whether the outdoor patch changed during that same period. If you could not safely access the meter, leave that check to the utility.
Bill
Billing dates, usage units, and whether the comparison is against a similar season.
Meter
Start and end readings, times, and any use that could not be paused.
Yard
Photos, irrigation timing, and whether the wet patch appeared or grew.
Next contact
Ask the utility to interpret the account and meter
Have the bill in front of you and ask whether the usage is based on an actual or estimated reading, what the meter serves, whether an outdoor irrigation meter is separate, and whether the utility offers leak alerts or a meter check. Ask who is responsible for the service line at your property; that boundary varies by utility and location.
If the utility confirms unexplained use but cannot identify its source, a licensed plumber or irrigation professional can assess the relevant system. Share the dates, readings, irrigation schedule and dated yard photos. If usage looks normal but the rain-linked wet area keeps returning, use the rain-runoff guide instead of treating the bill as proof of a supply leak.
