Water Meter and Service Line Leaks:

The Warrenton Water and Sewer Department’s policy is that the customer is responsible for their own system. The amount of water that goes through the meter will be billed to the customer for water and sewer charges. The Customer can check for leaks in their own system. There is a small red triangle on the face of the meter that is called the leak indicator. You need to make sure every faucet/water supply in the house is off (washing machine, faucets inside and outside, toilets, etc.)   Then look on the face of the meter at the leak indicator. You will have to watch this for at least 10 minutes. If you see any movement in the leak indicator, or if the number changes on the register, you have a leak.   The customer is responsible for sewer service lines at the property line or easement line; where the stop box and cleanout should be located. If you should have problems with either water or sewer from that point in, it will be for you, or the property owner to repair. The Warrenton Water and Sewer Department only maintains from those points out, as well as water and sewer mains.   If the water meter breaks due to negligence such as freezing, you will be billed for the cost of a new meter.
