IFrom the brief story I would think you have a leaking water service entrance.
Try shutting off the valve in the house and open the lowest faucet and when the water pressure goes away and there is no dripping see if the meter is moving. If there is no dripping then this rules out the bad shut off valve.
If it is constantly moving you should start to see the gound soft sometimes not. If you know how the entrance is run get a probing rod and probe sometimes you will be able to pull mud up on the rod sometimes not. I had an entrance at the meter 9' dt deep.
Something you might not rule out is that you have a bad meter..yes it happens. Ask the city to replace it. Might even lower you water bill.
More than likely it's the service line.
How old is the line and what is it? PVC, Copper, Galv ect
