Irish Water meters feature Automatic Meter Reading (AMR) technology and are fitted with a transmitter that periodically sends water meter readings to a receiver unit in one of our meter reading vehicles. This means we can conduct water meter readings remotely using scheduled ‘drive by’ technology. The water meter for your property will usually be read every three months in this way and the readings will be provided to you as part of your bill. AS such, there is no requirement for you to read the water meter for your property, however, should you wish to read your water meter, please ensure that it is safe for you to do so or ask a friend or family member to help you.


Please read our safety guidelines on accessing and reading your water meter.

To take a meter reading:

How to take a water meter reading:
  1. The serial number on your meter will match the serial number on your bill. The meter serial number is a combination of both letters and numbers of either 10 or 11 characters depending on the type of water meter that you have. There are two types of water meters, namely Diehl and Itron. Please refer to the images below for the location of the serial number on each of these meters. The serial number on your bill will be referred to as the ‘Meter no.’ in the ‘Bill detail’ section. By matching the serial number on your meter to the serial number on your bill will help you to read the correct water meter.
  2. You will see that the dials are divided into two sections - a black and red section. Read the dials from left to right taking note of all the digits in the black dials and the first two digits in the red dials.

Note: The Diehl water meter has a clear lid which covers the dials. You must lift the lid in order to see the dials. The red dials may be difficult to read on the Diehl meter, in particular, the last digit is obscured.
