Drinking water quality

Report water quality issues

We work hard to ensure that the water you receive is of the highest standard and have consistently improved the quality of water in Northern Ireland over the last few years.

However, if you are concerned about the water we supply to your home, please contact us on Waterline: 0345 744 0088 so we can investigate the problem.

If appropriate, we will take samples for analysis and let you know as soon as possible, depending on the nature of test carried out.

If you complain of illness which you believe may be related to water quality, we will visit you to take a sample and we will let you know the results as soon as possible.

Where we find a problem that might affect your health, we will advise everyone in the affected area what to do. This may mean boiling water before use, or in exceptional cases, not using it until we have carried out further tests. This advice will come to you through notices posted to you, local media news bulletins, personal visits or by phone – whichever is the quickest and most effective way to get the message to you.

Lead in water

There is virtually no lead in drinking water as it leaves our treatment works or our mains. Any lead in drinking water usually comes from lead service pipes or domestic plumbing, mainly found in older properties.

If you are concerned about lead in your drinking water, we can test a sample of your water supply. Please contact us on Waterline: 0345 744 0088 for advice about replacing lead pipes.
