A boil water notice has been issued for parts of County Waterford following an issue at a water treatment plant supplying drinking water to around 11,000 customers.

Uisce Éireann says the notice affects customers supplied by the Glenary Public Water Supply after a problem overnight impacted the plant’s ability to adequately disinfect the water supply.

The notice covers parts of Clonmel and surrounding areas, including the Kilcomma and Fingerpost areas of County Waterford.

Customers are being advised to boil water before drinking it, making drinks, preparing food that will not be cooked, brushing their teeth or making ice.

The notice was issued following consultation with the HSE to protect public health.

Uisce Éireann says drinking water experts are working to resolve the issue at the treatment plant and lift the notice as quickly and safely as possible.

Customers can check if their property is affected through the Water Quality section of water.ie by entering their Eircode or by calling Uisce Éireann’s customer care helpline on 1800 278 278.

The utility says water remains safe to consume once it has been boiled.
