Not if the leaking pipe is on your business’s property. Your water meter/s will have been fitted at the boundary of your premises, and as soon as the water passes through the meter/s, the water supply, including the pipes, becomes your responsibility.
One of the best ways of assessing whether or not there’s an underground water leak is to understand your business’s normal water usage. The way to do this is to take regular meter readings so over time you’ll get to know how much water your business uses as a matter of course. This means that if your water meter reading shows a sudden increase in water usage that you can’t explain, it’s a good indication you need to investigate whether or not you have an underground leak.
If you have AMR (Automatic Meter Reading) installed on your premises, you will be alerted as soon as it detects high water usage, speeding up the process of leak detection even further.
There is also another, simple way using your water meter to help you double check your suspicions before calling in specialists to help you find leaks:
Out of hours meter readings
If you suspect you have a water leak, you can do a simple test outside working hours. Wait until there is no-one left in the building, and take a meter reading. Turn the water off at the stopcock and wait for half an hour. Then take another meter reading. If the reading is higher even though no-one was in the building and the water was off anyway, there’s a high likelihood that there’s a leaking pipe. The higher the meter reading, of course, the bigger the leak.
