A water meter is a device which measures the amount of water supplied to your home. Meters will be placed in a meter box, which will be fitted underground on public land outside your property. These water meters will feature Automated Meter Reading (AMR) technology.

Find out more about Irish Water meters and AMR technology here.

These water meters can be read by a 'drive by' method rather than by an individual visit by a meter reader. This means we won't need to enter your property to take a reading and we can read them more efficiently. AMR water meters also provide information about the household's water usage so we are able to show you how much water you have used. By knowing a bit more about how much you use it will hopefully make it easier to manage your water usage.

Water meter installation:

  1. At least 14 days before the work begins you will receive a booklet by post that explains our work and what to expect when we install your water meter. 
  2. At least two days before the installation we will notify you of the date when the water meter will be fitted.
  3. The installation process may restrict access to your driveway and will cause disruption to the public road or footpath outside your home and in your area which may last for a few days. This is unavoidable but we will try to keep disruption to a minimum and make sure that you have safe pedestrian access to and from your home while work is being carried out. Protective barriers will be used throughout the installation process for your safety. Typically, works will take place between 7.30am and 7.30pm Monday to Friday and between 8am to 1pm on Saturday.
  4. During the actual fitting of the water meter and/or meter box (which may take up to two hours) your water supply will be interrupted from time to time. While your water supply is off please:
    • don't use the kitchen cold water tap, or any other tap that is fed directly off the mains, as this could cause the sink to overflow if it is left on when supply is restored
    • don't drink water from your hot water tap
    • don't use household appliances such as washing machines and dishwashers, which rely on a constant supply of water
    • don't use other devices running on mains water pressure
  5. You do not need to be at home while your meter box or water meter is being fitted and there is no direct charge for the fitting of a water meter.

Accessing your water meter:

When accessing your water meter please be aware of your surroundings, your personal safety and the safety of others. We try to locate water meter boxes out of the way of traffic, however, please remain aware of cyclists, pedestrians and other road users. If you have mobility concerns we recommend that you ask a neighbour or family member to help you access your water meter. Do not try to read the water meter yourself as it may involve bending, crouching and kneeling on the ground. If your meter has a metal lid, please contact Irish Water

To take a water meter reading:

  1. The serial number on your water meter will match the serial number on your bill. The water meter serial number is a combination of both letters and numbers of either 10 or 11 characters depending on the type of 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 water 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 water meter to the serial number on your bill will help you to read the correct meter for your property.
  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 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 as the last digit is obscured. However, you will not be billed on single litres so you do not need to take note of the last digit in the red dials.
