If you suspect you have a leak, make sure no water is running inside (washers are off, etc.).  Go outside and locate your water meter, typically it's on the edge of your property in a box with a metal lid.  There are usually two meters inside, yours and your neighbors.  Yours is the one closest to your property.  If you are able to open the lid, look at the face of the meter, it is similar to a car's odometer.  Watch it for five minutes.  If the red, orange, or black triangle, or silver star (depending on the brand of meter you have, see picture to right) moves during this time, then water is going through the meter, which means something is using water on your property.  You will need to call a plumber to locate the leak and repair it. 

You can call the City at 218-5555 to request a leak check on your meter.
