A water meter is a device which measures the amount of water supplied to your property. Approximately 1 million domestic customers have had meters installed by Irish Water while the vast majority of non-domestic customers are also metered.

Domestic Metering

Meters for people’s homes are placed in a meter box, which is located underground on public land. These meters will feature Automated Meter Reading (AMR) technology. This means that the meter can be read by Irish Water on a drive by/walk by basis and will not require the customer to be present to read the meter.

The current metering programme has been completed, but if there is a need to install or replace a new meter, customers can expect that the work may disrupt water supply to the property for a few hours. Property owners do not need to be present during meter installation and Irish Water will keep disruption to a minimum.

Irish Water will provide information on the process involved in installation to households at least 2 weeks before, and will then notify of the date of installation at least 2 days beforehand.

Reading your meter

If you wish to read your own meter, it is possible to do so. When accessing your water meter please be aware of your surroundings, your personal safety and the safety of others.

If you have mobility concerns you may wish to 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.

There are two types of water meters that have been installed by Irish Water and these are called Diehl and Itron. There are images below which show the two meters and where to locate the serial (or meter) number on each.

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 and red sections. The black digits indicate the number of cubic litres used (a cubic litre is equal to 1,000 litres). The red digits show the number of litres used (fractions of a cubic litre).

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, in particular, the last digit is obscured.

There is more information on metering available on the Irish Water website. This includes instructional videos on how to read your meter. To view this information, go to the metering section of the Irish Water website.

Non-Domestic Metering

The vast majority of non-domestic premises have already had water meters installed. Approximately only 10% of non-domestic customers are unmetered at this time.
