First, make sure all valves are turned off and there are no leaking faucets or toilets. Then, you want to locate your meter box, which is typically located in front of your property near the street. Carefully remove the lid and raise the cap on the meter dial. The display dial is similar to a clock; locate the red triangle at the lower left side on the dial of meter. The triangle should not turn unless you are using water. If the triangle is turning, you may have a leak.
